Researchers Refine Estimates of Earth’s Deep Carbon Cycle

Over billions of years, the total carbon content of the outer part of the Earth — in its upper mantle, crust, oceans, and atmospheres — has gradually increased, scientists reported this month in the journal Proceedings of the National Academy of Sciences.

VCU Researchers to Use Newly Developed Metrics to Study Impact of Ecosystems on Climate

For decades, scientists have relied on an established formula to measure the impact of greenhouse gas emissions on climate change.

New Computations to Help Climate Scientists Monitor Evolution of CO2 in Atmosphere

How light of different colours is absorbed by carbon dioxide (CO2) can now be accurately predicted using new calculations developed by a UCL-led team of scientists. This will help climate scientists studying Earth's greenhouse gas emissions to better interpret data collected from satellites and ground stations measuring CO2.

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.
