In a new study, scientists found that aerosol particles released into the atmosphere from the burning of fossil fuels are a primary driver of changes in rainfall patterns across the globe.

The results of the climate system-model simulations conducted by researchers Brian Soden and Eui-Seok Chung from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science revealed that changes in clouds, as a result of their interaction with these man-made aerosols in the atmosphere, are driving large-scale shifts in rainfall and temperature on Earth.

Marine scientists from Oxford’s, Department of Zoology, have presented a United Nations (UN) panel with an overview of the risks facing our oceans.The UN members were meeting for the latest round of negotiations towards a possible high seas treaty.

The Oxford report reveals the severe risk to the open ocean from climate change, over-fishing, deep-sea mining, farm and plastics pollution. The paper calls for immediate legal protection of the high seas.

A tiny sea snail, sometimes called a sea butterfly because of how it flutters about traveling the ocean currents, is part of the diet for such valuable fish as salmon and cod off the U.S West Coast.

A new study models the journey of this delicate plankton from offshore to nearshore waters, describing how changing ocean chemistry along this journey affects their condition.

Photosynthesis, which allows energy from the sun to be converted into life-sustaining sugars, can also be hazardous to green plants. If they absorb too much sunlight, the extra energy destroys their tissue.

To combat this, green plants have developed a defense mechanism known as photoprotection, which allows them to dissipate the extra energy. Researchers from MIT and the University of Verona have now discovered how the key protein in this process allows moss and green algae to protect themselves from too much sun.

The expansion of renewable energy has been widely criticised for increasing weather-dependent fluctuations in European electricity generation. A new study shows that this is due less to the variability of weather than from a failure to consider the large-scale weather conditions across the whole continent: many European countries are unilaterally following national strategies to expand wind energy capacities without looking beyond their own backyard.

It would be better, however, for individual countries to work together and to promote the expansion of wind capacity in other European regions that are currently making very little use of wind power.  Balancing capacity across the continent would effectively minimise the extreme fluctuations caused by the varied weather conditions that currently affect wind speeds. This is the conclusion reached by a group of weather and energy researchers from ETH Zürich and Imperial College London in a new study, which has just been published in the journal Nature Climate Change.

Just as one too many cocktails can lead a person to make bad choices, a few drops of oil can cause coral reef fish to make poor decisions, according to a paper published today in Nature Ecology & Evolution. A team of fisheries biologists led by Jacob Johansen and Andrew Esbaugh of The University of Texas Marine Science Institute have discovered that oil impacts the higher-order thinking of coral reef fish in a way that could prove dangerous for them—and for the coral reefs where they make their home.

A study in the Marcellus Shale region of western Pennsylvania has shown that even after being treated, wastewater from hydraulic fracturing operations left significant contamination in a waterway downstream of treatment plants. 

Researchers from Penn State University, Colorado State University, and Dartmouth College studied sediments from Conemaugh River Lake — a dammed reservoir east of Pittsburgh — and found that they were contaminated with endocrine-disrupting chemicals called nonylphenol ethoxylates; polycyclic aromatic hydrocarbons, which are carcinogens; and elevated levels of radium. 

Could the storms that once engulfed the Great Plains in clouds of black dust in the 1930’s once again wreak havoc in the U.S.? A new statistical model developed by researchers at Princeton University and the National Oceanic and Atmospheric Administration (NOAA) predicts that climate change will amplify dust activity in parts of the U.S. in the latter half of the 21st century, which may lead to the increased frequency of spectacular dust storms that have far-reaching impacts on public health and infrastructure.

Forest birds on the island of Hawaii are responding positively to being restored in one of the largest, ongoing reforestation projects at Hakalau Forest National Wildlife Refuge, according to a new study released July 10 in the journal Restoration Ecology.

Serving as pollinators and seed dispersers, birds have an important role in ecosystem function and their presence in restoration areas can be a measure of success for conservation efforts.

NOAA and its research partners predict that western Lake Erie will experience a significant harmful algal bloom this summer, potentially reaching levels last seen in 2013 and 2014, though smaller than the record bloom of 2015.

This year’s bloom is expected to measure 7.5 on the severity index, but could range between six and 9.5. An index above five indicates a potentially harmful bloom. The severity index is based on a bloom’s biomass – the amount of its harmful algae – over a sustained period. The largest blooms, 2011 and 2015, were 10 and 10.5, respectively.
