Tropical peatland carbon losses from oil palm plantations may be underestimated
Draining tropical peatlands for oil palm plantations may result in nearly twice as much carbon loss as official estimates, according to a new study by researchers from the University of Minnesota Institute on the Environment and the Union of Concerned Sci >

Amazon Absorbs Less Carbon Dioxide as Trees Die Off, Study Says
The Amazon rain forest has long absorbed more carbon than it releases and acted as a vital brake on climate change. An extensive study now suggests that it is losing its ability to suck up the excess carbon dioxide being emitted into the atmosphere by hum >

Emissions by Makers of Energy Level Off
Somebody tapped the brakes. Carbon dioxide emissions from the world’s energy producers stalled in 2014, the first time in 40 years of measurement that the level did not increase during a period of economic expansion, according to preliminary estimates... >

Hidden greenhouse emissions revealed in new report
Restoration of wetlands can reduce greenhouse gas emissions. This is shown in a report that has been written in part by researchers from the University of Gothenburg. >

February carbon dioxide levels average 400ppm for first time
The US government’s greenhouse gas monitoring site at Mauna Loa in Hawaii has confirmed that its average recorded carbon dioxide levels for February topped 400 parts per million (ppm) - the first time that this has been seen in a northern winter month. >

The Not So Brief History of Climate Change Science
It’s 2015, and climate change is one of the biggest challenges of our time. But while it may seem like all of this fuss over global warming is a recent phenomenon, concern over the role of atmospheric carbon dioxide in our planet’s climate has a long hist >
