NTNU Membrane-Based Technology Holds Promise for Full-Scale CO2 Capture in Cement Factories

The cement industry is one of the largest sources worldwide of carbon emissions, accounting for around five per cent of global emissions. New technologies being developed by the Norwegian University of Science and Technology may help substantially lower these emissions.

Atmospheric Oxygen Levels Have Significantly Altered Global Climate

Variations in the amount of oxygen in Earth’s atmosphere significantly altered global climate throughout the planet’s history. Efforts to reconstruct past climates must include this previously overlooked factor, a new University of Michigan-led study concludes.

Melting Glaciers Will Release Massive Amounts of Organic Carbon and Affect Aquatic Ecosystems

As the climate warms, glaciers and other terrestrial ice reservoirs will release massive amounts of organic carbon into the water circulation. Just how much and how quickly it will be released is the focus of a recent Nature Geoscience publication.

UK NERC Awards £3 Million Grant for Research into Accelerated Melting of Greenland Ice Sheet

Global warming alone is not enough to account for the increasingly rapid melting of the ice sheet. Other factors are darkening the ice sheet surface, which results in greater rates of melting.

Carbon Dioxide-Caused Warming Exceeds Amount of Heat Released by Combustion-Caused Warming

The heat generated by burning a fossil fuel is surpassed within a few months by the warming caused by the release of its carbon dioxide into the atmosphere, according to new work from Carnegie's Xiaochun Zhang and Ken Caldeira published in Geophysical Research Letters, a journal of the American Geophysical Union. The release of CO2 into the atmosphere contributes to the trapping of heat that would otherwise be emitted into outer space.

Research Predicts Broad-Scale Global Climate Change That Could Last For Years

A new study, by scientists from the University of Southampton and National Oceanography Centre (NOC), implies that the global climate is on the verge of broad-scale change that could last for a number of decades.

Climate Change May Cause More Powerful Hurricanes, Tropical Storms

Climate change may be the driving force behind fewer, yet more powerful hurricanes and tropical storms, says a Florida State geography professor.

New Light on Ice Sheet Evolution and Their Contribution to Sea Level Rise

ULB study sheds a new light on the stability of the Antarctic ice sheet. It shows for the first time that ice rises (pinning points that keep the floating parts of ice sheets in place) are formed during the transition between glacial and interglacial periods, which significantly slows down the response of the ice sheet to climate change.

Implementation of the Montreal Protocol Benefits the Ozone Layer

We are already reaping the rewards of the Montreal Protocol, with the ozone layer in much better shape than it would have been without the UN treaty, according to a new study in Nature Communications.

Scientists Use Mineral Cave Deposits to Find Clues about Prehistoric Climate Changes

When the conversation turns to the weather and the climate, most people's thoughts naturally drift upward toward the clouds, but Jessica Oster's sink down into the subterranean world of stalactites and stalagmites.
