In an unusual new study, scientists say they have detected a growing fingerprint of human-driven global warming on global drought conditions starting as far back as 1900.

A new book, the second in a series of primers with the Earth Institute imprint, provides an interdisciplinary overview drought, bringing together many fields including climate science, hydrology and ecology.

A new study suggests bacteria may respire more carbon dioxide from the shallow oceans to the air as seas warm, reducing the deep oceans’ ability to store carbon.

New research shows that the Larsen C ice shelf—the fourth largest ice shelf in Antarctica—experienced an unusual spike in late summer and early autumn surface melting in the years 2015 to 2017.

A million years ago, a longtime pattern of alternating glaciations and warm periods dramatically changed, when ice ages suddenly became longer and more intense. Scientists have long suspected that this was connected to the slowdown of a key Atlantic Ocean current system that today once again is slowing. A new study of sediments from the Atlantic bottom directly links this slowdown with a massive buildup of carbon dragged from the air into the abyss.

Scientists are sailing to remote areas of the Southern Ocean to drill cores from the bottom that they hope will contain clues to past rapid changes in the Antarctic ice, and how it may react to warming climate today.

Biodiversity could suffer as result, and more carbon could be added to the atmosphere.

Measurements of stable isotopes in tree rings may expand the climate information that scientists can get from old trees.

Wallace Broecker, a geochemist who initiated key research into the history of earth’s climate and humans’ influence upon it, died Feb. 18 in New York. He was 87.

Earth’s global surface temperatures in 2018 were the fourth warmest since modern record keeping began in the 1880s, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration.
