Last winter’s El Niño might have felt weak to residents of Southern California, but it was in fact one of the most powerful climate events of the past 145 years.

Researchers from University of Gothenburg and the Swedish University of Agricultural Sciences (SLU) show that both species diversity and habitat diversity are critical to understand the functioning of ecosystems.

Scientists from the University of East Anglia and Ocean University China have discovered that tiny marine bacteria can synthesise one of the Earth’s most abundant sulfur molecules, which affects atmospheric chemistry and potentially climate.

This molecule, dimethylsulfoniopropionate (DMSP) is an important nutrient for marine microorganisms and is the major precursor for the climate-cooling gas, dimethyl sulfide (DMS).

AMHERST, Mass – A new study of songbird dehydration and survival risk during heat waves in the United States desert Southwest suggests that some birds are at risk of lethal dehydration and mass die-offs when water is scarce, and the risk is expected to increase as climate change advances.  

A study, led by Newcastle University’s Dr Alan Jamieson has uncovered the first evidence that man-made pollutants have now reached the farthest corners of our earth.

A new international study has demonstrated that deep-sea nodule mining will cause long-lasting damage to deep-sea life. This study, led by scientists at the National Oceanography Centre (NOC), was the first to review all the available information on the impacts of small-scale sea-floor disturbances simulating mining activity. It found clear impacts on marine ecosystems from deep-sea nodule mining activities, which lasted at least for decades.

Bacteria in certain microbiomes appear to help corals adapt to higher water temperatures and protect against bleaching, as shown by a KAUST-led research team.

A recent interpretive review of scientific literature performed by the U.S. Geological Survey and the University of Rochester sheds light on the interactions of gas hydrates and climate.

The breakdown of methane hydrates due to warming climate is unlikely to lead to massive amounts of methane being released to the atmosphere, according to a recent interpretive review of scientific literature performed by the U.S. Geological Survey and the University of Rochester.

Methane hydrate, which is also referred to as gas hydrate, is a naturally-occurring, ice-like form of methane and water that is stable within a narrow range of pressure and temperature conditions.  These conditions are mostly found in undersea sediments at water depths greater than 1000 to 1650 ft and in and beneath permafrost (permanently frozen ground) at high latitudes. Methane hydrates are distinct from conventional natural gas, shale gas, and coalbed methane reservoirs and are not currently exploited for energy production, either in the United States or the rest of the world. 

For the 100 million people who live within 3 feet of sea level in East and Southeast Asia, the news that sea level in their region fluctuated wildly more than 6,000 years ago is important, according to research published by a team of ocean scientists and statisticians, including Rutgers professors Benjamin Horton and Robert Kopp and Rutgers Ph.D. student Erica Ashe. That’s because those fluctuations occurred without the assistance of human-influenced climate change.

In a paper published in Nature Communications, Horton, Kopp, Ashe, lead author Aron Meltzner and others report that the relative sea level around Belitung Island in Indonesia rose twice just under 2 feet in the period from 6,850 years ago to 6,500 years ago. That this oscillation took place without any human-assisted climate change suggests to Kopp, Horton and their co-authors that such a change in sea level could happen again now, on top of the rise in sea level that is already projected to result from climate change. This could be catastrophic for people living so close to the sea.

Less than a year after the first research flight kicked off NASA’s Oceans Melting Greenland campaign, data from the new program are providing a dramatic increase in knowledge of how Greenland’s ice sheet is melting from below. Two new research papers in the journal Oceanography, including one by UCI Earth system scientist Mathieu Morlighem, use OMG observations to document how meltwater and ocean currents are interacting along Greenland’s west coast and to improve seafloor maps used to predict future melting and sea level rise.
