A new study from McGill University finds higher incidence of lung cancer and brain tumors in people exposed to wildfires.

Scientists investigating the underside of the world’s largest ice sheet in East Antarctica have discovered a city-size lake whose sediments might contain a history of the ice sheet since its earliest beginnings.

Global warming can result in the spread of peatland vegetation in the Arctic. 

Ice shelves are floating extensions of glaciers. If Greenland’s second largest ice shelf breaks up, it may not recover unless Earth’s future climate cools considerably. 

As rising seas increase saltwater intrusion and soaring temperatures cause greater evaporation, scientists say that the mounting levels of salt in waters and in soils pose a major climate-related danger and could become a leading cause of climate migration globally.

A by-product released by use of fossil fuels has been increasing since 1974

A new survey of flying insects in Britain found their numbers have dropped nearly 60 percent since 2004, a “terrifying” decline given the vital role that insects play in pollinating crops, consuming organic waste, and killing pests, advocates say.

The world’s ocean is steadily losing its year-to-year memory due to global warming, according to a study published in Science Advances co-authored by a University of Hawai‘i at Mānoa atmospheric scientist. 

Earth system scientists at the University of California, Irvine and other institutions have drawn the clearest line yet connecting consumers of agricultural produce in wealthier countries in Asia, Europe and North America with a growth in greenhouse gas emissions in less-developed nations, mostly in the Southern Hemisphere.
