Undersea Earthquakes Shake up Climate Science

Despite climate change being most obvious to people as unseasonably warm winter days or melting glaciers, as much as 95 percent of the extra heat trapped on Earth by greenhouse gases is held in the world's oceans.

Climate Changed in Steps in the Past

An international study published in Science significantly improves the potential for understanding how the Earth's climate system evolved over the past 66 million years.

How Cold Was the Ice Age? Researchers Now Know

A University of Arizona-led team has nailed down the temperature of the last ice age - the Last Glacial Maximum of 20,000 years ago - to about 46 degrees Fahrenheit.

Historical Climate Changes Occurred Simultaneously in Several Parts of the World

A new study published by researchers from the University of Copenhagen and partner institutions has proven that repeated and abrupt climate changes during the last ice age occurred simultaneously in South America, Southeast Asia, Europe and Greenland.

Research Links Southeast Asia Megadrought to Drying in Africa

Physical evidence found in caves in Laos helps tell a story about a connection between the end of the Green Sahara, when once heavily vegetated Northern Africa became a hyper-arid landscape, and a previously unknown megadrought that crippled Southeast Asia 4,000 to 5,000 years ago.

Fossil Leaves Show High Atmospheric Carbon Spurred Ancient ‘Global Greening’

Scientists studying leaves from a 23-million-year-old forest have for the first time linked high levels of atmospheric carbon dioxide with increased plant growth, and the hot climate off the time.

Innovative Method Opens up New Perspectives for Reconstructing Climatic Conditions of Past Eras

Corals precipitate their calcareous skeletons (calcium carbonate) from seawater. Over thousands of years, vast coral reefs form due to the deposition of this calcium carbonate.

New Study Supports Predictions That the Arctic Could be Free of Sea Ice by 2035

A new study, published this week in the journal Nature Climate Change, supports predictions that the Arctic could be free of sea ice by 2035.

Volcanic Eruptions Responsible for Cooling of Earth Around 13,000 Years Ago

Ancient sediment found in a central Texas cave appears to solve the mystery of why the Earth cooled suddenly about 13,000 years ago, according to a research study co-authored by a Texas A&M University professor.

Biodiversity Surrounding the Tibetan Plateau Shows How Climate Change Can Affect Evolution

One of the big questions in biology is why certain plants and animals are found in some places and not others.

The Middle Holocene, a Plausible View of the Future

Global warming will modify the distribution and abundance of fish worldwide, with effects on the structure and dynamics of food networks.

Study Analyses 500 Years of Floods in Europe

An international research project coordinated by the Vienna University of Technology (TU Wien), with participation from researchers of the University of Barcelona, shows for the first time that flood pattern over the last decades in Europe have changed compared to past centuries.
