Researchers analyzed an ice core from Greenland and found that fires in the North Atlantic region decreased over 4,500 years ago due to weaker summer insolation and expanding glaciers. Human interference, such as Viking colonization, also played a role in reducing fire frequency.
A new study reveals an invisible layer of biological compounds on the sea surface can reduce carbon dioxide gas exchange by up to 50 percent. This finding has major implications for predicting future climate, as it suggests slower removal of anthropogenic carbon dioxide from the atmosphere.
The American Meteorological Society (AMS) is showcasing recent advancements in hurricane forecasting, climate trends, and the long-term impact of CO2 emissions. A new study reveals improved forecast capabilities, while another paper examines the causes of seasonal and regional climate trends over the United States.
Researchers at the University of Iowa have developed a method to estimate photosynthetic uptake by plants over large regions, improving accuracy of global warming and land cover change estimates. By analyzing carbonyl sulfide levels, scientists can quantify human-generated CO2 emissions and develop better management strategies.
The global survey found that about half of anthropogenic CO2 is taken up by the upper 10% of the ocean. Rising CO2 levels may alter marine food webs and diversity, threatening calcifying organisms.
