Scientists from around the world argue that the suggested afforestation of large areas of Africa to mitigate climate change will destroy valuable ecological, agricultural, and tourist areas, while doing little to reduce global CO2 levels.
Read moreResearchers report that in order for a 90-meter ice cliff to collapse entirely, the ice shelves supporting the cliff would have to break apart extremely quickly, within a matter of hours — a rate of ice loss that has not been observed in the modern record.
Read moreResearchers describe the emerging role of ecophysiology in riparian flooding. As an adaptation to an overabundance of carbon dioxide in the atmosphere, trees, plants and grasses constrict their stomatal pores to regulate the amount of the gas they consume, a mechanism that limits the release of water from leaves through evaporation. This saturates soils and causes more efficient run off and river flooding.
Read moreSince the 1970s, insects in the warmer half of Britain have been flying, hopping and crawling northwards at an average rate of around five metres per day. However, a new study has analysed 25 million recorded sightings of 300 different insect species and found there is huge variation in the rates at which they are moving and that not all species are able to keep pace with the warming conditions.
Read moreThe ways climate scientists explain their predictions about the impact of global warming can either promote or limit their persuasiveness.
Read moreGeophysicists complete their analysis of a well-documented seismic event that held many surprises.
Read moreGreenhouse gases may get more attention, but aerosols — from car exhaust to volcanic eruptions — also have a major impact on the Earth's climate. Using a massive NASA dataset, researchers have created a framework that helps explain just how sensitive local temperatures are to aerosols.
Read moreDuring Earth's last glacial period, temperatures on the planet periodically spiked dramatically and rapidly. A new article suggests that mathematics from information theory could offer a powerful tool for analyzing and understanding these mysterious events.
Read moreAs global temperatures continue to rise, the thawing of permafrost is accelerated and mercury trapped in the frozen ground is now being released. The mercury is transforming into more mobile and potentially toxic forms that can lead to environmental and health concerns for wildlife, the fishing industry and people in the Arctic and beyond.
Read moreIn 2018, vast amounts of snow were spread across most of the Arctic region and did not melt fully until late summer, if at all. Researchers documented the consequences of this extreme weather event at Zackenberg, Northeast Greenland by extensively monitoring all components of the local ecosystem for more than 20 years, allowing them to compare life in the extreme year of 2018 to other, more 'normal,' years.
