Carbon Emissions ‘Will Threaten Crops and Human Nutrition’
Increasing carbon dioxide concentrations will threaten crops and levels of human nutrition around the world. That’s according to researchers from the Harvard Chan School, which examined the impact of the gas on iron, protein and zinc levels in 225 different…
Fast-Melting Lakes Could Increase Permafrost Emissions 118 Percent
Scientists may need to more than double their assessment of how much carbon dioxide and methane thawing Arctic permafrost will release into the atmosphere this century, according to a study published this month. The paper, published in Nature Communications Aug.…
Trees Are Migrating West to Escape Climate Change
An individual tree has roots and, of course, it doesn’t move. But trees, as a species, do move over time. They migrate in response to environmental challenges, especially climate change. Surprisingly, they don’t all go to the Poles, where it…
Indonesia’s Deforestation Dropped 60 Percent in 2017
In the midst of the second-worst year for tropical tree cover loss in 2017, Indonesia saw an encouraging sign: a 60 percent drop in tree cover loss in primary forests compared with 2016. That’s the difference in carbon dioxide emissions…
‘Turning CO2 into Useful Products Such As Concrete Will Incentivise Decarbonisation’
The University of Michigan says removing carbon dioxide from the air must be incentivised by turning the gas into a useful commodity. Its $4.5 million (£3.5m) ‘Global CO2 Initiative’ aims to reduce the equivalent of 10% of current atmospheric carbon…
Study Finds New Reason to Ban Plastic: It Emits Methane in the Sun
The proliferation of plastic pollution has led to concerns over its impact on marine life and human health as the toxins it absorbs and emits move up the food chain. Now, a new study reveals yet another potential plastic hazard:…
UK Government to Promote Green Alternatives to Inhaler F-Gases
The UK Government will continue to work to reduce harmful F-gas emissions, which are commonly found in fridges and asthma inhalers. That’s according to its response to a report from the Environmental Audit Committee, which examined progress on reducing the…
