In a new paper, climate scientists at the University of Massachusetts Amherst and Woods Hole Oceanographic Institution propose that massive amounts of melting sea ice in the Arctic drained into the North Atlantic and disrupted climate-steering currents, thus playing an important role in causing past abrupt climate change after the last Ice Age, from about 8,000 to 13,000 years ago. Details of how they tested this idea for the first time are online now in Geology.
The atmospheric release of ancient stores of methane in thawing permafrost or from beneath Arctic ice may not impact future climate warming as strongly as previously believed, a new study finds.
As global temperatures rise, permafrost and methane hydrates -- large reservoirs of ancient carbon -- have the potential to break down, releasing enormous quantities of the potent greenhouse gas methane. But would this methane actually reach the atmosphere? University of Rochester researchers and their collaborators found that even if methane is released from these natural stores in response to warming, very little reaches the atmosphere; therefore, anthropogenic emissions should be more concerning than these natural feedbacks.
Rapid Arctic warming has not led to a 'wavier' jet stream around the mid-latitudes in recent decades, pioneering new research has shown.
University of Rochester researchers and their collaborators measured methane levels in ancient air samples and found that scientists have been vastly underestimating the amount of methane humans are emitting into the atmosphere via fossil fuels. In a paper published in Nature, the researchers indicate that reducing fossil fuel use is a key target in curbing climate change.
Institutional investors are factoring climate risks into their investment decisions, according to a first-ever survey conducted by the McCombs School of Business at The University of Texas at Austin.
Global schemes to fight climate change may miss their mark by ignoring the "fundamental connections" in how food is produced, supplied and consumed, say scientists in a new paper published in the journal Nature Food.
Winds outside of Tropical Storm Gabekile are ripping the storm apart. NASA's Aqua satellite provided a visible image of the storm that showed strong northwesterly wind shear was adversely affecting the storm.
A top ten of record-breaking US weather events of the last decade reveals Hurricane Harvey is the most extreme of the decade, and similar others were among the costliest and deadliest on record, according to magazine Weatherwise.
Aerosol emissions from burning coal and wood are dangerous to human health, but it turns out that by cooling the Earth they also diminish global economic inequality, according to a new study by Carnegie's Yixuan Zheng, Geeta Persad, and Ken Caldeira, along with UC Irvine's Steven Davis.
