Superficial permafrost could (almost) disappear by 2100

,
By the end of the century, near-surface permafrost may exist only in the highlands of eastern Siberia, the High Arctic and northern Greenland. As was the case 3 million years ago

Climate change puts 40 percent of biodiversity in eastern Brazil at risk

,
In the Catinga forest rising temperatures threaten to destroy nearly half the biodiversity by 2060, a Brazilian study says. Ecosystem services are under threat

This is how climate change will alter U.S. agriculture

,
Climate change is set to impact agricultural yields in the U.S. Midwest, a study by the University of Connecticut says. "Data suggest a 12 percent decrease in corn yields by around 2050 and 40 percent by the end of the century"

Urbanization promotes increasing emissions from the soil

,
As a result of urbanization, soil nitrous oxide emissions increase 153%, according to a new study. At the same time, the ability to absorb methane is reduced

Here’s how drought stress alters soil function in the rainforest

,
Drought progressively reduces the ability of soil to consume biogenic volatile organic compounds according to a German study. The emission intensifies after soil rewetting
