Prime Minister Theresa May also pledged to share the UK’s expertise to help nations transition to cleaner and greener energy systems.

The UK Government has committed £169.5 million of funding to support developing countries affected by climate change.

Prime Minister Theresa May made the announcement at the UN General Assembly in New York this week and pledged to share the UK’s expertise to help nations transition to cleaner and greener energy systems.

She set out £94.5 million on mitigating the effects of climate change, which would provide support to families most affected by droughts in Northern Kenya and £60 million of technical assistance to share the UK’s expertise on energy market reform, green finance and climate legislation.

Around £15 million will be provided support companies buying food from farmers in Sub-Saharan Africa, helping to build resilience against rising food demand and climate shocks.

In addition, she said the UK would help gather evidence on the actions needed to adapt to climate change and join the Carbon Neutrality Coalition to support the ambitious action of global net zero emissions.

The UK also called for a third of the world’s oceans to be protected from damaging activity by 2030 at the UN General Assembly.

UN Environment conducted a five-day training workshop in Baghdad with officials from the Environment and Oil Ministries on practical aspects of sites, with a focus on sampling strategies and techniques.

It comes as Iraq has seen extensive destruction of infrastructure and looting – from oil resources to archaeological artefacts – by Islamic State in Iraq and the Levant (ISIL).

The officials have given portable oil contamination analysers and sampling tools as well as personnel protective equipment to support the assessment campaign.

They will carry out field surveys of oil contaminated sites in four areas – Nineveh, Salah El-Deen, Kirkuk and Diyala – after which UN Environment will review the findings and provide guidance on site prioritisation process.

The survey will aim to identify priority sites for clean-up that pose a serious risk to human health and the environment.

UN Environment is guiding the mapping campaign through an initial inventory of around 60 oil-contaminated sites, including satellite maps.

Dr Jassim Humadi, Iraq’s Deputy Environment Minister said: “I cannot overstate the need to strengthen the capacity of our environment experts in assessing contaminated site and oil activities and to develop polluting monitoring programmes which represent not only a threat to local communities but whose impacts will also extend for generations to come. During the past few years, Iraq has undergone a transformative leap in its oil production driven by large investments. This poses a major capacity challenge for environment staff to monitor and oversee the industry’s performance, assess the current situation and extrapolate future projections.

“We commend UN Environment’s contaminated site assessment training programme, which is assisting environmental institutions in Iraq to fulfil their responsibility in achieving environmental security in accordance with the objectives of sustainable development to protect the environment and the public health of citizens.”

Two-headed Copperhead

Earlier this month, a young two-headed Eastern Copperhead was found in Northern Virginia. The finder emailed the Virginia Herpetological Society for identification; DGIF was then alerted and the state herpetologist picked up the snake. This week, he brought it to the Wildlife Center for radiographs. Dr. Ernesto [who is a big fan of venomous snakes] examined the baby copperhead.

It appears as though the left head is more dominant – it’s generally more active and responsive to stimulus. Radiographs revealed that the two-headed snake has two tracheas [the left one is more developed], two esophaguses [the right one is more developed], and the two heads share one heart and one set of lungs. Based on the anatomy, it would be better for the right head to eat, but it may be a challenge since the left head appears more dominant.

Wild two-headed snakes are extremely rare – they just don’t live that long. The herpetologist will continue monitoring the snake; if it survives, it will likely be placed in an educational facility.

Judge Stops Bear Hunt and Returns Yellowstone Grizzlies to the Endangered List

The hunt for grizzlies in Yellowstone National Park is officially over. This week, a judge ordered that all grizzly bears living in or near the park to be put back on the list of endangered species. The ruling stops the attempts of wildlife officials to issue licenses for those want to hunt the bears, which have been protected from hunting for the past four decades.

According to The Guardian, the population of grizzly bears has increased in the last 30 years from around 135 to more than 700 today. While the numbers are improving, grizzlies are only present in four locations in the Rocky Mountains. This has raised concerns about the recovery of grizzlies, as the populations are still isolated from each other. This is one reason why Judge Dana Christensen, who put in a lot of research on the case, decided to put the bears back on the endangered list. As Judge Christensen explained, true recovery means expanding grizzly populations to regions outside of the Rocky Mountains.

While environmental groups and activists praised the ruling, wildlife officials were disappointed by the turn of events. Officials in Wyoming recently put in motion plans for a bear hunt later this year. Up to 22 individuals were granted licenses to hunt grizzlies when the season opened.

Luckily, citizens and conservationists launched a massive campaign — including the Shoot’em with a Camera, Not A Gun initiative — to stop the sport hunting of these beautiful creatures.

The fight to keep grizzly bears on the endangered list is sadly not over. Experts believe that state officials will attempt to repeal the ruling at a higher court. The pro-hunting organization Safari Club International is also expected to make a push toward making grizzly hunts legal once again.

We can only hope that Judge Christensen’s ruling stands the test of time, allowing grizzlies to make a true recovery in the wild.

Taller Plants Moving into Warmer Arctic

Photo-illustration: Pixabay

The low-lying shrubs, grasses and other plants growing in the Arctic are getting taller.

The finding comes from scientists who have analysed three decades of measurements. This data, gathered across Alaska, Canada, Iceland, Scandinavia and Russia, indicates that a warming climate is driving the change. The team of 180 researchers says the increase in height could ultimately work to push up temperatures further.

The international group reports its work in the journal Nature.

Co-lead author Isla Myers-Smith, from the University of Edinburgh, UK, predicted that, on their current trajectory, the centimetres-tall Arctic flora could double in size by the end of the century.

“That doesn’t seem like a very dramatic increase, but if you compare it to the ecosystems around your house like the forest nearby – if you imagined that forest getting twice as tall; that is a pretty dramatic change,” she told BBC News.

Plants have to be hardy to flourish in the far north or high up Alpine mountains.

The cold and short growing season precludes trees. Instead, this tundra landscape is populated by small species that hug the ground. But the Arctic is undergoing rapid change.

Recent decades have seen the region experience some of the fastest rates of warming on the planet. It is not simply that existing plants have increased their stature, although that is the case; it is more that taller species are now invading areas they never used to grow in large numbers.

As an example vernal sweetgrass, which is common in lowland Europe, has now moved into the research plots in Iceland and Sweden where long-term monitoring is undertaken.

Why Does Height Matter?

The re-profiling of plant communities is important because it could alter the way the tundra ecosystem functions.

Taller Arctic plants will trap more snow around them, insulating the ground from very cold air and preventing it from freezing quite so hard. This makes it easier for usually rock-solid soils to thaw out in summer months and release their carbon into the atmosphere. This would add to the warming.

Taller plants could also effect the same outcome because, by sticking their heads above the snow, they would present a darker surface, and that allows the ecosystem to trap more heat from the Sun.

“Although there are still many uncertainties, taller tundra plants could fuel climate change, both in the Arctic and for the planet as a whole,” said the study’s other co-lead investigator, Anne Bjorkman, from the Senckenberg Biodiversity and Climate Research Centre, Germany.

How Does This Study Stand Out?

It is remarkable because of its scale. It incorporates more than 60,000 data observations from hundreds of sites across the Arctic and in the European Alps and the American Rockies.

The information reaches back through the decades, enabling it to reliably catch real trends.

Scientists will revisit specific locations to take the same measurements over and over again. These measurements cover everything from plant height and leaf area to wood density, seed size, leaf chemistry, and more.

Those researchers who initiated the earliest data collections could never have known precisely how their persistence would eventually pay off. They would just have had the recognition that long observation series are invaluable.

“One of the goals of our project was to make this database publicly available so that future researchers can ask questions that we can’t anticipate right now either,” said Dr Myers-Smith.

Google, World Bank and EU Among Key Players Pledging Climate Action at One Planet Summit

Photo: YouTube (screenshot)

Political and business leaders met in New York Wednesday to reaffirm their commitment to fighting climate change at the second annual One Planet Summit

The summit was hosted as part of Climate Week NYC by French President Emmanuel Macron, United Nations Secretary General António Guterres, World Bank President Jim Yong Kim and UN Special Envoy for Climate Action Michael R. Bloomberg to mobilize finance behind climate action, according to a press release.

It also comes as world leaders are gathered in New York for the 73rd session of the UN General Assembly and follows a harsh UN address by Macron Tuesday during which he said he would refuse to negotiate commercial deals with any country that did not join the Paris agreement.

The U.S. is currently the only country not pledging to follow the agreement after President Donald Trumpannounced plans to withdraw last year.

Macron did not mention Trump by name Wednesday, but alluded to his actions during his remarks.

“The Paris agreement was supposed to be dead because of one decision,” Macron said, according to Bloomberg News.

But the summit wasn’t just to rally verbal support for Paris in defiance of Trump.

“We are not here just to speak but to be accountable,” Macron said. “Here we will see what is working and what is not working. What we need is action.”

Several business leaders announced pledges designed to help lower global greenhouse gas emissions, Reuters reported.

The world’s largest asset manager BlackRock promised to help craft an investment fund to finance renewable energy and low-carbon transport in Africa, Asia and Latin America.

The World Bank pledged to launch a $1 billion platform for developing battery storage technology.

Google, meanwhile, said it would launch a tool to measure greenhouse gas emissions from traffic and use Google Earth to measure the solar capacity of world cities.

Bloomberg announced that he would help organize a Wall Street Network on Sustainable Finance to encourage more climate and environment financing in U.S. markets, according to a press release provided by Bloomberg Philanthropies.

Political leaders also stepped up to the plate.

The European Commission promised 25 percent of the next EU budget, 320 billion euros, to climate initiatives, according to the same press release.

The EU also joined with France and New Zealand to launch the Joint Pacific Initiative for Biodiversity, Climate Change and Resilience to the tune of 20 million euros.

In total, more than 40 business and civic leaders gathered to report on the progress of 30 initiatives announced at the first One Planet Summit in December 2017, as well as to pledge new commitments.

“Cheesy” Solar Charger Kit Empowers Students in East Africa

Foto: YOLK

Playful in its design and highly functional, SunMade Cheese features a charger for flashlights, lighters, radios and even cellphones powered by mere sunlight. The device was developed by YOLK, the solar company applauded for its Kickstarter project ‘Solar Paper’ in 2015 that has sold millions of dollars worth of units worldwide. This time, it seems whimsy has struck the cutting-edge solar tech firm, which decided to express its love of cheese in this new project. Continuing its sun-charged aspirations, the group has debuted quirky, cheese-plate-shaped solar panels and cheese-shaped, solar-powered accessories with a meaningful mission to boot.

Photo: YOLK

YOLK is eager to attract current generations to solar energy, making it easy to incorporate the technology in their daily routines. The group also hopes to improve energy infrastructure and conservation in developing nations as well as put an end to child labor, instead empowering families to send children to school.

Rather than tackling these issues separately (as is common), YOLK decided to put its creativity to the test and develop the Solar Cow in conjunction with the new cheese chargers. The Solar Cow systems are much larger solar energy generators built with a portion of the revenue that YOLK receives from SunMade Cheese. The company is deploying the conductive cows in remote areas of East Africa that are burdened by poor energy infrastructure.

As many as one in every five children are prevented from attending school in East Africa. Families rely on child labor to supplement the household income. Besides providing power to local schools, the Solar Cow will provide an incentive for parents to send their children to school instead of sending them off to work. In the mornings, students are able to attach batteries to the “cow’s udders” for charging and take them home at night with a full supply of free, clean energy.

Photo: YOLK

“The SunMade Cheese project is more about enjoying solar power and promoting education for solar technology, but the Solar Cow is really a lifeline for people,” YOLK CEO Sen Chang explained. “They are two projects for two different perspectives, but combined in one initiative.” Families in rural areas commonly travel around four to six hours in order to reach a charging station to juice up their cellphones. The mobile phones are a necessity, because they facilitate communication to the rest of the world and a means to make payments and receive income. The cost of this process is astounding, with the average family spending approximately 10-20 percent of their total monthly earnings to simply charge their cellular devices an average of 10-12 times per month.

The SunMade Cheese charger is the perfect accessory to promote an environmentally friendly lifestyle at home while assisting YOLK’s efforts to help communities abroad. Stressing creativity and efficiency, the award-winning innovators deserve to bask in the sunlight for their life-changing technological designs. No doubt, many will join them — cheese plate in hand!

Air Pollution Fears Fuel Fight Against New London Cruise Ship Terminal

Photo-illustration: Pixabay

The River Thames has become a ‘wild west’ unbound by new laws to clean up the city’s roads, say campaigners.

A huge new cruise ship terminal planned for the River Thames would lead to a surge in dangerous levels of air pollution in the heart of the capital with unknown health consequences for hundreds of thousands of people, campaigners have warned.

Under the proposals, which have been given planning permission, up to 55 giant cruise ships would dock in London every year. Each ship would need to run its diesel engines round the clock to power onboard facilities, generating the same amount of toxic NO2 emissions as almost 700 continuously running lorries.

“As we find out more about the damage air pollution is doing to people’s health it is unthinkable that something like this can go ahead,” said local resident Laura Eyres, who is one of those leading the fight against the development.

Photo-illustration: Pixabay

“There is simply no justification for having these huge ships sitting here right next to busy residential areas and schools, belching out this level of pollution with all the associated damage to people’s health that have now been proven.”

Residents want it to be “zero emissions”, only allowing ships that can plug into an onshore power point so they can turn off their polluting diesel engines.

Eyres said: “With 55 cruise ships planned annually and each staying for three days we face huge amounts of sulphur dioxide, nitrogen dioxide and particulate matter being released into our homes every day of the summer with potentially devastating health implications.”

One of the big cruise ship companies, Viking, said its ships were already fitted with the “latest technology that meets the strictest environmental regulations”.

A spokesman added: “If shore side power were available then we would consider using it. In fact, we are already prepared to use shore power. Our newest ship, launched this year, has a built-in connection, and we are updating our other four ships to use shore power in order to have the capability fleetwide.”

Campaigners wrote to Morgan Stanley earlier this month raising their concerns again and arguing the current plans were at odds with the company’s stated commitment on environmental sustainability.

A spokesperson for the company said it had received the letter and was working on revised plans for the development.

“We acknowledge East Greenwich Residents Association’s concerns and can assure [them] that our new proposals will take these concerns into account.”

However, Eyres said local residents needed more than encouraging words. “We can’t rest until we see a concrete commitment from Morgan Stanley that their plans for a polluting cruise port are dead in the water.”

There has been growing concern about the scale of the air pollution crisis in recent months. A slew of new research has highlighted the health risks associated with toxic air – from reduced intelligence to a rise in asthma deaths; heart disease to spikes in alzheimer’s and dementia.

However, the River Thames does not fall under his jurisdiction and campaigners fear it has become a “wild west” in terms of air pollution.

“The fumes that are emitted on the river simply would not be allowed if they were coming from a road in London,” said Eyres. “It is really worrying to think what damage these fumes are causing local residents, and if the new terminal goes ahead that is only going to get a lot worse.”

The Port of London Authority (PLA) controls traffic on the Thames and admits the “marine sector” has lagged behind in terms of tackling air pollution.

However, it says it is catching up and earlier this year it produced its first air quality strategy. It points out that the Thames is only responsible for 1% of London’s air pollution and says emission levels will improve in the years ahead as clean marine technology comes into force.

Martin Garside from the PLA said it was working with the the mayor and local authorities to “to secure strong environmental standards”.

He added: “With a single barge carrying the loads of 50 lorries – the Thames helps reduce traffic and pollution on London’s congested roads. Over four million tonnes of cargo is transported between river terminals – removing about 300,000 lorry movements from the roads.”

The proposed new cruise terminal at Enderby Wharf in Greenwich is owned by Morgan Stanley, which was given planning permission for the terminal and wider residential development by Greenwich council in 2012 and updated permission in 2015.

Now the council has changed its mind and is backing campaigners’ calls for Morgan Stanley to come up with a greener alternative for the cruise terminal.

They aim to reduce emissions from upstream operations to below 0.25% by 2025.

Thirteen of the world’s biggest oil and gas companies have agreed a first collective target to reduce methane emissions.

They have announced a goal to cut methane intensity from their upstream oil and gas operations to below 0.25% by 2025.

The methane intensity refers to the methane that gets lost in the atmosphere when producing oil and gas.

The target was unveiled at the Oil and Gas Climate Initiative’s (OGCI) fourth annual meeting and could see emissions reduce by 350,000 tonnes every year.

The companies part of OGCI are BP, Chevron, CNPC, Eni, Equinor, ExxonMobil, Occidental Petroleum, Pemex, Petrobras, Repsol, Saudi Armaco, Shell and Total.

The heads of the OGCI firms said: “Our aim is to work towards near zero methane emissions from the full gas value chain in support of achieving the goals of the Paris Agreement. We have worked to make our ambition concrete, actionable and measurable, helping to ensure that natural gas can realise its full potential in a low emissions future.”

Vanishing Joshua Trees: Climate Change Will Ravage US National Parks, Study Says

Photo-illustration: Pixabay

Park lands have warmed twice as fast as the rest of the country.

America’s national parks have warmed twice as fast as the US average and could see some of the worst effects of climate change, according to a new study.

Most of Joshua Tree national park could become uninhabitable for its eponymous trees, glaciers will continue to melt away at Glacier national park, and many other of America’s most treasured beauty spots could be rendered virtually unrecognizable by climate change, Patrick Gonzalez, the lead author of the study, writes in the journal Environmental Research Letters.

Even the tiniest of creatures are at risk in the worst-case predictions: the American pika, a small alpine mammal, may no longer be able to survive on park land.

Photo-illustration: Pixabay

“We are preserving the most remarkable ecosystems, and they happen to be in extreme environments,” said Gonzalez, a climate scientist at the University of California, Berkeley. Gonzalez is also the principal climate change scientist for the US National Park Service but conducted and spoke about the research in his university capacity.

The study finds that temperatures in national parks could go up 3 to 9C by 2100, under the Intergovernmental Panel on Climate Change’s worst-case scenario, which shows what could happen without policies to decrease greenhouse gas pollution. With lower emissions, temperatures could still exceed 2C for 58% of park land, compared to 22% of the US as a whole, according to the study.

They are particularly vulnerable because most US park land is in areas that are heating up quicker: in the mountains, the Arctic and the dry south-west.

Alaska parks would see the most extreme heat increases, and the US Virgin Islands parks face 28% less rainfall by the end of the century. In Glacier Bay national park, the Muir Glacier melted 640 meters between 1948 and 2000.

In Yellowstone national park, trees are dying because bark beetles are thriving in warmer winters. Yellowstone will also become far more vulnerable to wildfires. The area burned could be up to three to 10 times higher by 2100. Joshua Tree national park in California could lose up to 90% of the habitat suitable for its namesake trees.

Gonzalez explained that parks at a higher elevation have a thinner atmosphere that warms faster. Hotter temperatures are also melting snow cover and making the ground darker so that it absorbs more heat. Parks in California and the south-west US have seen both high temperatures and record-low rainfall, he said.

The research is the first comprehensive look at climate change impacts on national parks, Gonzalez said. He said he has been using the climate impacts research to develop plans for parks to adapt and reduce the greenhouse gas pollution they contribute.

The Trump administration has rescinded government efforts to slow climate change. The interior department, where the National Park Service is housed, nixed a policy that would have urged management decisions based on science, including climate change research. Park officials in New England scrubbed references to climate change and flooding risks in a report this summer, according to Reveal. The National Park Service did not immediately respond to a request to comment on the study or climate change policies for parks.

Jonathan Jarvis, the National Park Service director under Barack Obama who now also works at UC Berkeley, said he relied on climate change projections to decide where to relocate and bolster structures in the Everglades national park in Florida, an area that has been hit by hurricanes and faces sea-level rise.

Jarvis said he worries that under Trump parks won’t be able to plan long-term for climate change.

“The park service manages these assets, these places, for the benefit of the American people, and they should be based on the best available sound science in the long-term public interest, not for some short-term political agenda,” Jarvis said.

URBIGO: Cherry Tomatoes and Chillies from a Green Cube

Gardening has always involved owning a piece of land, and garden plants would bear fruits as a result of time, effort and knowledge a man has invested in. If a city dweller wanted to grow his plants, he would have to own a cottage with a garden or at least strips of land around his house, and also to spend some time learning the gardening basics as well as practising techniques whose intensity varies depending on the season. The one who did not have a plot of land could only dream of sweet-smelling and fresh produces from his own crops.

By implementing the modern concept of urban gardening and vertical gardens all around the world, inhabitants at urban areas also got a chance to grow herbs, strawberries and cherry tomatoes on small land lots managing even to apply the main principles of organic production which means that no pesticides, artificial fertilizers, chemically treated seeds, etc are allowed.

Recently, a step forward has been made. Thanks to a local team of young experts, an urban gardener – by definition without a land – now doesn’t need to have any knowledge about agriculture, nor to worry about weather conditions, nor to spend much time to take care of his plants. All he needs is “Green Cube”.

A fledgeling company “UrbiGo”, founded by Anja Carapic, Aleksandar Varnicic, Predrag Gajic and Milan Trajkovic, made a portable smart garden and gave it a name “Green Cube”. Having witnessed the challenges of an intensive urbanization and overpopulation in cities that led to a gradual shrinkage of green areas, these young people wanted to find a solution for a new generation that is raised in “concrete jungle” and in an environment which is increasingly polluted. It appears that a small garden is an ideal choice for growing herbs or miniature vegetables throughout the year and at any place in a home.

Anja Carapic, an environmental engineer and the only lady in this team of four innovators, told us that they had a strong motive since there was a product missing from the market, the one designed to all urban residents who do not have enough space, time or knowledge to become owners of their own piece of greenery and to grow their own groceries.

“Many have tried, frequently with no success, to grow various plants at home. We noticed that they had been spending a lot of money on different solutions for urban gardening, but they were all too complicated, big or noisy. We wanted to make a product that will make the cultivation much easier”, says Anja. If we also take into account the fact that today people generally show interest, if not concern, about the quality of food which they keep buy- ing at the supermarkets, it’s not unusual that they want to grow plants and pick fresh produces.

Upon reflecting on the fact that most people in city do not have even a terrace suitable for cultivating at least certain types of fruits and vegetables, this team of innovators has realized that it is necessary to create an advanced and autonomous garden solution – plants must be provided with all that they need to grow in the conditions that were previously considered completely inadequate for cultivation and which posed an obstacle for any kind of “gardening”.

“With the ‘Green Cube’, you no longer need a terrace, garden or plenty of space. The garden has an automatic lighting and self-watering system so it informs you when it’s thirsty, that is to say when you need to water it (generally on 3 or 4 weeks), or when you should turn the light on or off, regardless of where you are at that moment. And here comes its main advantage. All of this you can actually do with one click on your mobile phone”, says Anja. Through the free application, the company UrbiGo developed, it is now possible to monitor vital factors of plants such as temperature, light and water level at any time and from any place, which enables the urban gardener to pick fresh spices or miniature vegetable produces in just 2.5 months. As the breeder moves forward in his gardening adventure, he unlocks new levels in the application, gets recipes and tips, and learns what are the benefits of cultivating different plants in his garden.

We Believe in Smart Gardens but also in Smart Gardeners

Photograph: URBIGO TEAM

According to Anja, the main users of “Green Cube” are primarily millennials, young business people aged from 23 to 36 years who have a hectic lifestyle, yet want to have a healthier diet. There are companies on the waiting list for this product who want to make their workspace greener and connect their employees with nature. Families with children are also interested in the “Green Cube” because parents believe it’s better for children to learn about nature while the children themselves are engaged taking care of plants, and to spend time on a phone in a more meaningful way by using this application instead of just playing the games.

Congress Poised to Act to Reduce Major Source of PFAS Chemicals in Drinking Water

Photo-Illustration: Pixabay

House and Senate leaders included a provision in legislation to fund the Federal Aviation Administration and strengthen disaster programs that will give commercial airports the option to switch to firefighting foams that do not include the highly toxic fluorinated chemicals known as PFAS.

Under current law, airports are required to use firefighting foams that contain these chemicals, which have been linked to cancer, kidney disease and other health issues.

Firefighting foams made with PFAS chemicals are a significant and widespread source of drinking water contamination.

In March, Washington became the first state to ban the use of PFAS chemicals in firefighting foams. Congress could vote later this week on the bill that includes the option for airports to switch to PFAS-free foam.

The bipartisan group of lawmakers from both chambers who lead negotiations of the final package were House Transportation and Infrastructure Committee Chairman Bill Shuster (R-Pa.); Senate Commerce, Science, and Transportation Committee Chairman John Thune (R-S.D.); House Transportation and Infrastructure Committee Ranking Member Peter DeFazio (D-Ore.); and Senate Commerce, Science, and Transportation Committee Ranking Member Bill Nelson (D-Fla.).

“EWG appreciates the bipartisan group of leaders who came together to tackle this serious and growing threat to the nation’s drinking water,” said EWG Legislative Attorney Melanie Benesh. “On behalf of communities grappling with PFAS-contaminated tap water, EWG applauds their leadership on this important issue. Safeguarding the public from the dangers posed by toxic chemicals in our tap water should be a top priority for all our elected leaders.”

New Study Reconciles a Dispute About How Fast Global Warming Will Happen

Photo-illustration: Pixabay

Unfortunately, mainstream climate scientists are still right, and we’re running out of time to avoid dangerous global warming.

We’re currently on pace to double the carbon dioxide-equivalent (including other greenhouse gases) in the atmosphere by around mid-century.  Since the late 1800s scientists have been trying to answer the question, how much global warming will that cause?

Photo-illustration: Pixabay

In 1979, top climate scientists led by Jule Charney published a reportestimating that if we double the amount of carbon dioxide in the atmosphere from pre-industrial levels of 280 ppm to 560 ppm, temperatures will warm by 3 ± 1.5°C.  Four decades later, ‘climate sensitivity’ estimates remain virtually unchanged, but some climate contrarians have argued that the number is at the low end of that range, around 2°C or less.

It’s an important question because if the contrarians are right, the 2°C resulting global warming would represent significantly less severe climate change consequences than if mainstream climate scientists are right and temperatures rise by 3°C.  It would also mean our remaining carbon budgetfor meeting the 2°C Paris target is about twice as large than if the mainstream consensus is right.  If the consensus is correct, we’re on pace to blow through the remaining Paris carbon budget by around 2030.

Another Nail in the Contrarian ‘Low Sensitivity’ Coffin

Studies published in March 2014, May 2014, and December 2015 identified two critical flaws in the contrarians’ preferred so-called ‘energy balance model’ approach: it doesn’t account for the fact that Earth’s sensitivity can change over time, for example as large ice sheets continue to melt, or that the planet responds differently to different climate ‘forcings’.

Last week, the journal Earth’s Future published a study by the University of Southampton’s Philip Goodwin that took both of these factors into account.  Goodwin ran climate model simulations treating every forcing separately, including changes in greenhouse gases, solar activity, particulates from volcanic eruptions, and from human fossil fuel combustion.  For each, he included feedbacks from changes in factors like atmospheric water vapor, clouds, snow, and sea ice, including how these factors change over different timescales, as Goodwin explained:

I ran 10 million simulations with a relatively simple climate model. These 10 million simulations each used different climate feedback strengths, and so the way that climate sensitivity responded over time was different in each simulation.  To check which of the 10 million simulations were most realistic, I checked each simulation against observations of warming in the atmosphere and ocean up to the present day. I kept only the simulations that agreed with the observations for the real world.

This left 4600 simulations, where the values of the climate sensitivity (and changes in climate sensitivity over different timescales) agree with the atmosphere and ocean warming observed so far. It is from these final 4600 simulations that evaluate how the climate sensitivity evolves over time.

Essentially, adding up all of the warming contributions from all of these factors at any given time tells us how sensitive the climate is on that timescale, whether it be a month, a year, a decade, or a century after atmospheric carbon dioxide levels have doubled.

Over the shortest timeframes of a year or less, Goodwin found that temperatures will rise by about 2°C once carbon dioxide levels have doubled, consistent with the conclusions of the contrarian studies.  That makes sense because those studies applied current climate measurements into energy balance models, but since carbon pollution is still rising, the climate still has a large energy imbalance.  Climate sensitivity, on the other hand, is usually evaluated at the point when the Earth reaches a new energy equilibrium, long after carbon dioxide levels have stopped rising.

Once our carbon pollution levels decline close to zero (hopefully by mid-to-late century), the planet will start to reach that new equilibrium.  The slower feedbacks like melting ice will continue to kick in, and Goodwin found that on timescales close to a century thereafter, temperatures will rise by 1.9–4.6°C, most likely 2.9°C, consistent with mainstream climate science estimates since the 1979 Charney report.

We Need to Hit the Brakes or Blow Past Paris

Climate contrarians want to gamble on the long shot that the climate sensitivity is on the low end of the possible range, which would give us a few extra decades before we burn past the Paris target.  But even that relatively rosy scenario would require more aggressive international climate policies than are in place today.  We still have to change course even to limit ourselves to a doubling of carbon dioxide-equivalent in the atmosphere.

And the body of scientific research keeps refuting the contrarian case.  If anything, recent research suggests the climate sensitivity is toward the high end of the possible range, but Goodwin’s study finds that it’s most likely right where climate scientists have expected for decades. As Goodwin concluded,

”some of the lowest estimates of climate sensitivity from before do not appear to hold on the long timescales.”

Co-Op to Replace Single-Use Plastic Bags with Compostable Ones

Co-op has announced plans to scrap single-use plastic bags at its stores and replace them with biodegradable ones.

The supermarket expects the move to eliminate around 60 million plastic bags as part of its phased rollout.

Lightweight compostable carrier bags, which can be reused as food waste caddy liners, will be rolled out to almost 1,400 Co-op stores across England, Scotland and Wales – initially in towns, cities and villages where the bags are accepted in food waste collections.

The initiative is part of Co-op’s plans to eliminate its own-brand black and dark plastic packaging, including ready meal trays, by 2020 and its own-brand packaging to become recyclable by 2023.

It has also pledged to use a minimum of 50% recycled plastic in bottles, pots and trays by 2021.

Retail Chief Executive Jo Whitfield said: “The price of food wrapped in plastic has become too much to swallow and from today, the Co-op will phase out any packaging which cannot be reused.

“The first step to remove single-use plastic will be to launch compostable carrier bags in our stores. They are a simple but ingenious way to provide an environmentally-friendly alternative to plastic shopping bags.”

The supermarket sources 100% renewable energy for its stores and claims to have reduced plastic use equivalent to taking out 125 million plastic water bottles from production so far.
