Warming global temperatures are changing life on every continent on Earth, including Antarctica, where more microbes are moving in to territory previously covered by ice. How these microbes respond to warming offers us clues about what future Antarctica will look like and who will thrive there. Microbial ecologist and PhD candidate Alicia Purcell from the Center for Ecosystem… Read more

The world’s oceans are getting hotter and acidifying under climate change at unprecedented rates, threatening coastal and high-mountain communities, marine ecosystems and global fishing stocks, according to a new Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) released this week by the United Nations Intergovernmental Panel on Climate Change. Ted Schuur, a researcher in the Center for Ecosystem Science and Society (Ecoss) at Northern Arizona University, was one of the lead authors on the… Read more
As the climate changes, extreme weather and flooding are intensifying and occurring more frequently worldwide. Scientists believe that by studying warming events in Earth’s past, they can better understand how the current warming trend is triggering other changes to the environment.
As part of a large, multidisciplinary study involving eight institutions and a multimillion-dollar National Science Foundation… Read more

The ancient Nasca civilization, which flourished hundreds of years before the Inca along the southern coast of Peru, could be considered one of the earliest examples of a culture adapting to climate change. The Nasca thrived in one of the driest deserts in the world by growing corn and potatoes to sustain them, building an impressive irrigation system of… Read more
The boreal forest is home to one-third of the Earth’s forest cover and stores 40 percent of the planet’s terrestrial carbon. North America’s boreal forest alone, which spans the northern portion of the continent from Alaska all the way to Newfoundland, covers an astounding 1.5 billion acres—more than 2.3 million square miles.
As mega-fires in the boreal forest become more frequent and more intense, scientists believe the burning of these… Read more
Findings of a new study organized by the Permafrost Carbon Network (PCN) suggest that putting more effective greenhouse gas controls in place for the rest of this century could help mitigate the effects of climate change on the release of carbon from thawing soils of the northern permafrost region.
