The ice in Antarctica has melted before

Recent research by Norwegian University of Science and Technology revealed that East Antarctica's ice sheet melted rapidly along its margins between 9,000 to 5,000 years ago. The study suggests that the less stable, rapidly flowing parts of the ice sheet were broken up more easily, leading to the ice sheet becoming much thinner within ...

2021-like North American heat extremes: Increased impact of heat domes due to background warming and soil moisture feedback

The study found that heat domes over Western North America contributed 50% of the observed high temperatures in 2021-like heatwaves. The intensities of these extreme heat events are projected to increase by 40-fold by the end of the century, emphasizing the need for climate mitigation and adaptation activities.

Global warming undermines greenhouse gas sink function of pristine wetlands

A new study published in Nature Climate Change reveals that pristine wetlands are currently a greenhouse gas sink, but this function will be reduced by over half in response to a 1.5-2°C temperature increase. Warming promotes net methane and nitrous oxide emissions from these ecosystems, posing a positive feedback on global warming.

A viscious circle: Climate change affects greenhouse gas emissions from stream networks

A new study by Linköping University reveals that climate change alters natural greenhouse gas fluxes from streams and lakes, making landscape carbon sinks less effective. The researchers found that increased precipitation and temperature affect the amount of carbon washed into streams and lakes, leading to greater emissions.
