Widespread forest management and protections against deforestation can help mitigate climate change - but will come with a steep cost if deployed as broadly as policymakers have discussed, new research suggests.
The continents will reunite again in the deep future. And a new study, presented today during an online poster session at the meeting of the American Geophysical Union, suggests that the future arrangement of this supercontinent could dramatically impact the habitability and climate stability of Earth. The findings also have implications for searching for life on other planets.
Planting trees and preventing deforestation are considered key climate change mitigation strategies, but a new analysis finds the cost of preserving and planting trees to hit certain global emissions reductions targets could accelerate quickly.
New international research by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) warns that green energy projects can be as socially and environmentally conflictive as fossil fuel projects. While renewable energies are often portrayed as being environmentally sustainable, this new study cautions about the risks associated with the green energy transition, arguing for an integrated approach that redesigns energy systems in favor of social equity and environmental sustainability.
The frozen permafrost in the Arctic is thawing on an alarming scale. By analysing an annual record of satellite images, researchers at the Alfred Wegener Institute have now confirmed these findings: thermokarst lakes in Alaska are draining one by one because warmer and wetter conditions cause deeper thaw, effectively weakening frozen ground as a barrier around lakes. In the season 2017/2018, lake drainage was observed on a scale that scientists didn't expect until the end of the century.
A group of experts from academic, governmental and international organisations have identified five large-scale 'megatrends' affecting forests and forest communities, published today in Nature Plants. These are likely to have major consequences - both positively and negatively - over the coming decade.
Groundwater reservoirs in Bavaria have warmed considerably over the past few decades. A new study by researchers at Martin Luther University Halle-Wittenberg (MLU) compares temperatures at 35 measuring stations, taken at different depths, with data from the 1990s. Water found at a depth of 20 metres was almost one degree warmer on average than 30 years ago. The findings were published in the journal 'Frontiers in Earth Science'.
New research found that wild cousins of sorghum, the fifth-most important cereal crop globally, are most concentrated in Australia, despite having been domesticated in Africa. But with 12 of the total 23 wild relative species possibly endangered, four vulnerable, and four near threatened, these economically important wild plants are in peril.
The number of wildfires and the amount of land they consume in the western US has substantially increased since the 1980s, a trend often attributed to ongoing climate change. Now, new research finds fires are not only becoming more common in the western US but the area burned at high severity is also increasing, a trend that may lead to long-term forest loss.
New University of Colorado Boulder research reveals that emissions are not growing as fast as the UN's Intergovernmental Panel on Climate Change's assessments have indicated--and that the IPCC is not using the most up-to-date climate scenarios in its planning and policy recommendations.
