Continuing CO2 Emission Trends Would Leave Legacy of Heat and Acidity in Deep Ocean

Continuing current carbon dioxide (CO2) emission trends throughout this century and beyond would leave a legacy of heat and acidity in the deep ocean. These changes would linger even if the atmospheric carbon dioxide concentration were to be restored to pre-industrial levels at some point in the future, according to a new Nature Climate Change paper from an international team including Carnegie’s Ken Caldeira. This is due to the tremendous inertia of the ocean system.

China Must Reduce Dependency on Coal for Long Term Energy Security

China needs to reduce its dependence on coal and improve the range of fuels it uses if it is to have long term energy security, according to new research from the University of East Anglia (UEA).

New Study Addresses Accuracy of Climate Model Projections

A new study led by a University of York scientist addresses an important question in climate science: how accurate are climate model projections?

Soot Pollution on Himalayan-Tibetan Plateau Contributes to Earlier Snowmelt , Shrinking Glaciers

Using a climate model that can tag sources of soot from different global regions and can track where it lands on the Tibetan Plateau, researchers have determined which areas around the plateau contribute the most soot -- and where. The model can also suggest the most effective way to reduce soot on the plateau, easing the amount of warming the region undergoes.

Lichens, Mosses and Cyanobacteria Release Large Amounts of Greenhouse Gas

Inconspicuous creatures surprise with a property that is important for our climate: Lichens, mosses and cyanobacteria release large quantities of the greenhouse gas nitrous oxide (N2O), also known as laughing gas, and low quantities of methane (CH4) into the atmosphere.

Stronger Precipitation Extremes Observed Due to Ocean Warming

That the temperatures on our planet are rising is clear. In particular, the increasing emissions of greenhouse gases such as carbon dioxide continue to warm the atmosphere. The effects of global warming on the hydrological cycle, however, are still not fully understood. Particularly uncertain is how the strength of extreme summertime thunderstorms have changed, and how it may change in the future.

Pacific and Indian Oceans Trap Extra Heat from Greenhouse Gases

A new NASA study of ocean temperature measurements shows in recent years extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans.

Just Slight Global Warming has Led to Significant Rise in Global Sea Levels

A new review analyzing three decades of research on the historic effects of melting polar ice sheets found that global sea levels have risen at least six meters, or about 20 feet, above present levels on multiple occasions over the past three million years.

New Study Suggests Climate Change is Unlikely to Result in Widespread Interbreeding

One of the questions raised by climate change has been whether it could cause more species of animals to interbreed. Two species of flying squirrel have already produced mixed offspring because of climate change, and there have been reports of a hybrid polar bear and grizzly bear cub (known as a grolar bear, or a pizzly).

Researchers Explore Links Between Climate and Vegetation Change

Significant changes in one of the Earth's most important ecosystems are not only a symptom of climate change, but may fuel further warming, research suggests.
