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.

Unsuitably Warm Temperatures Affecting Boreal Forest Growth in Interior Alaska

With warming summer temperatures across Alaska, white spruce tree growth in Interior Alaska has declined to record low levels, while the same species in Western Alaska is growing better than ever measured before.

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.

Warmer Water Temperatures May Push Marine Animals Away from the Equator

Modern mountain climbers typically carry tanks of oxygen to help them reach the summit. It's the combination of physical exertion and lack of oxygen at high altitudes that creates one of the biggest challenges for mountaineers.

Climate Change Causes Species Migration and Shrinking of Their Habitats

Many species are migrating toward Earth's poles in response to climate change, and their habitats are shrinking in the process, researchers say. Two new reports focusing on marine organisms, which have been moving pole-ward at higher rates than terrestrial creatures, show how factors, including those not directly related to climate change, are limiting the ranges of corals and fish.

Eemian Climate Evolution Could Serve as an Analogue for Future Warmer Climate

A new record of past climate change shows that a warm climate in northern Europe can be hit by a sudden cooling associated with an interruption of the North Atlantic Ocean circulation and the Gulf Stream. This is shown in a new study published in Quaternary Science Reviews, investigating the development of northern European climate about 120 thousand years ago.

World Can Avert Financial and Environmental Costs of Resource Depletion and Save Millions in Efficiency Gains – New UN Report Shows How

As the financial and environmental costs of resource depletion begin to affect economic growth worldwide, countries need to find ways to manage finite resources while meeting the needs of a growing and increasingly urban...

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.

Norwegian Climate Researchers and Ecologists Offer Insight on Impact of Climate Change on Seabirds

Collaboration between ecologists and climate researchers in Norway has generated fascinating new insight into how seabirds are affected by climate change.

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.
