Can biodiversity help protect ecosystems from extreme conditions? That question is much on the minds of scientists and policy makers as a changing climate brings more wildly swinging conditions at the same time human activities reduce the number of species available to produce food and oxygen and help keep our planet in balance.
Warming ocean temperatures a third of a mile below the surface, in a dark ocean in areas with little marine life, might attract scant attention. But this is precisely the depth where frozen pockets of methane 'ice' transition from a dormant solid to a powerful greenhouse gas.
A new study of the relationship between ocean currents and climate change has found that they are tightly linked, and that changes in the polar regions can affect the ocean and climate on the opposite side of the world within one to two hundred years, far quicker than previously thought.
Climate change is perhaps felt most acutely in the Arctic right now, but by the start of the next century, animal species in the Amazon basin region will be harder hit as the Earth warms.
As a new chairman is appointed to the Intergovernmental Panel on climate Change (IPCC) a University of Manchester climate expert has said headline projections from the organisation about future warming are ‘wildly over optimistic.’
Three leading Woods Hole Research Center (WHRC) experts on the threats of climate change in the Arctic will urge France's President Hollande and other political leaders to address the threat posed by thawing permafrost in the Arctic at the Arctic Circle Assembly in Reykjavik, Iceland on October 15.
While the U.S. Environmental Protection Agency (EPA) suggests there has been a decline in measurable atmospheric greenhouse gas emissions from fossil fuel use in the U.S. for the past seven years, a Cornell scientist says the EPA’s computation may be in error – by a wide margin – due to problematic accounting for natural gas, the so-called “bridge” fuel.
A new paper co-authored by WHRC scientists Philip Duffy and Paulo Brando evaluates the accuracy of current climate models and uses them to project future drought and wet periods in the Amazon. They conclude that the whole of the Amazon will confront more hydrological extremes, and that most of the region will experience much more frequent and extensive drought. These changes would have profound implications for forest structure, composition, biomass, and carbon emissions.
The Horn of Africa has become increasingly arid in sync with the global and regional warming of the last century and at a rate unprecedented in the last 2,000 years, according to new research led by a University of Arizona geoscientist.
Making predictions about climate variability often means looking to the past to find trends. Now paleoclimate researchers from the University of Missouri have found clues in exposed bedrock alongside an Alabama highway that could help forecast climate variability. In their study, the researchers verified evidence suggesting carbon dioxide decreased significantly at the end of the Ordovician Period, 450 million years ago, preceding an ice age and eventual mass extinction. These results will help climatologists better predict future environmental changes
