Edinburgh study finds evidence that ocean acidification was to blame for the Permian-Trias...

In order to better understand how climate change will unfold over the coming decades, some scientists are looking to the remote past and specific climatic catastrophes to help shed light the so-called Anthropocene and its consequences for life on Earth. Recently, researchers at the University of Utah looked into the so-called Paleocene-Eocene thermal maximum for clues. Now, a study by the University of Edinburgh highlights evidence that the rapid acidification of oceans 252 million years ago caused the greatest extinction of all time.  Read More

Those who question the environmental benefits of electric vehicles over their gas-guzzling brethren often point out that the electricity powering EVs usually comes from fossil fuel-burning power plants. But a study conducted by researchers at Michigan State University (MSU) and Hunan University in China has revealed some hidden benefits of EVs, regardless of where the electricity originates.  Read More

The new method looks for specific isotopes that point to the origins of methane samples (I...

An MIT-led team of researchers has developed an instrument capable of quickly and accurately analyzing samples of methane, pinpointing how they were formed. The breakthrough could give scientists a greater understanding of the role the gas plays in global warming.  Read More

The National Oceanography Centre in the UK has used data on the Arctic Ocean gathered by Royal Navy submarines to study the effects of a possible future shrinking of the ice cap. This meeting of oceanography and military intelligence has seen declassified data from the 1990s analyzed to gain insights into how diminished ice cover affects turbulence in arctic waters.  Read More

Both the ESA’s Sentinel-1A and CryoSat satellites have detected a significant degree of ice loss in the Austfonna ice cap, located on Norway’s Nordaustlandet island in the Svalbard archipelago. Parts of the ice cap have thinned by as much as 50 m (164 ft) since 2012 – around a sixth of its total thickness, and the speed of the outer glacier has increased to 3.8 km (2.4 miles) per year.  Read More

The DC-8 airborne laboratory is one of several NASA aircraft that will fly in support the ...

With the goal of shedding more light on a number of Earth system processes whose effect on our climate is incompletely understood, NASA will this year launch five new airborne field campaigns. These studies will look at long-range air pollution, warming ocean waters, melting Greenland glaciers, greenhouse gas sources, fires in Africa and clouds over the Atlantic, with the captured data to complement satellite- and surface-based observations to help provide a better understanding of the interconnected systems that affect our climate and how it is changing.  Read More

The banded sedimentary rock layers of the Willwood formation in Wyoming provide clues as t...

There's an element of déjà vu in the most recent political news on climate change: UN-led talks, like the recent Lima summit, that end with disgruntled environmentalists and plans for yet another summit. At this point, our best hope is to mitigate the effects of global warming (which is occurring faster than previously thought) and, if possible, keep temperature rises to a maximum of 2° C (3.6° F). While the future of the planet looks uncertain with unpredictable climate patterns, U.S researchers looking to the past to gain a better understanding of modern climate change have found the rate of modern, human-caused global warming resembles that which occurred almost 56 million years ago much more closely than previously thought.  Read More

The new CryoSat measurements show a 6.4 percent decrease in the volume of Arctic sea ice (...

The European Space Agency’s CryoSat mission has returned its latest map of Arctic sea ice volumes, recording a slight decrease in thickness over previous measurements. The data flies in the face of the previous downward trend, which was much greater, but is unlikely to indicate a shift in the accepted pattern of degradation.  Read More

The collapse of the Atlantic Meridional Overturning Circulation would trigger cooling and ...

We could see early warning signs of the collapse of a key component of the global climate up to 250 years in advance, a new study has shown – ample time to either prevent or prepare for the consequences of abrupt climate change. The University of Exeter study analyzed the Atlantic Meridional Overturning Circulation (AMOC), sometimes referred to as the global ocean conveyor belt, in a highly-complex and realistic simulation model, and identified the likely mechanisms that would drive such a collapse.  Read More

New research suggests that it takes just 10 years for CO2 emissions to have maximum effect...

Any given CO2 emission will have its maximum warming effect just 10 years later, new research from the Carnegie Institution for Science shows. The Institute of Physics (IOP) says this research, published in full on the web today, has "dispelled a common misconception" that the warming effects of CO2 emissions aren't felt for decades.  Read More
