A new study of three ice cores from Greenland documents the warming of the large ice sheet at the end of the last ice age – resolving a long-standing paradox over when that warming occurred.
Geologists in the College of Arts and Sciences have discovered a new way to study oxygen levels in the Earth’s oldest oceans.
The impact of the greenhouse gas CO2 on the Earth's temperature is well established by climate models and temperature records over the past 100 years, as well as coupled records of carbon dioxide concentration and temperature throughout Earth history.
Using sediments from a remote lake, researchers from Brown University have assembled a 60,000-year record of rainfall in central Indonesia. The analysis reveals important new details about the climate history of a region that wields a substantial influence on the global climate as a whole.
Scientists have developed a new approach to analyzing paleo-climate reconstructions of the El Niño Southern Oscillation (ENSO) phenomenon. Their findings resolve disagreements and reveals that activity during the 20th century has been unusually high compared to the past 600 years.
A recent discovery about earthworm excrement could help scientists improve our models of future climate change.
Researchers are looking to events of the past to better understand how rainfall patterns across the Indo-Pacific warm pool – the massive pool of warm water stretching along the equator from Africa to the western Pacific Ocean – will change due to global warming.
Harvard researchers are adding statistical nuance to our understanding of how modern and historical temperatures compare.
Earth's tropical climate history has been revealed in unprecedented detail – year by year, for almost 1,800 years – by two annually dated ice cores drawn from the tropical Peruvian Andes.
In the next few centuries, Canada's Arctic Archipelago glaciers will melt faster than ever, according to a new study. Research has revealed that 20 percent of the Canadian Arctic glaciers may have disappeared by the end of our current century, leading to an additional sea level rise of 1.4 inches.
