Climate risks for Gulf of Mexico coral reefs spelled out in study      (via sciencedaily.com) 

Ocean temperatures in the Gulf of Mexico and the Caribbean Sea are on pace to surpass critical thresholds for coral health by mid-century, but rapid action to significantly reduce emissions could slow warming, giving corals and coral conservation programs as much as 20 more years to adapt, according to new research.

Glass microspheres won't save Arctic sea ice      (via sciencedaily.com) 

A proposal to cover Arctic sea ice with layers of tiny hollow glass spheres about the thickness of one human hair would actually accelerate sea-ice loss and warm the climate rather than creating thick ice and lowering the temperature as proponents claim. Sea ice, by reflecting the majority of the sun's energy back to space, helps regulate ocean and air temperatures and influences ocean circulation. Its area and thickness is of critical importance to Earth's climate.

Coral select algae partnerships to ease environmental stress      (via sciencedaily.com) 

Corals live symbiotically with a variety of microscopic algae that provide most of the energy corals require, and some algae can make coral more resilient to heat stress. In assessing one of the main reef builders in Hawai'i, Montipora capitata or rice coral, researchers found that the symbiont community in those corals varied significantly in different parts of Kaneohe Bay.

Scientists find link between fast-melting Arctic ice and ocean acidification      (via sciencedaily.com) 

An international team of researchers has found acidity levels increasing three to four times faster than ocean waters elsewhere and a strong correlation between the accelerated rate of melting ice in the region and the rate of ocean acidification. This threatens the Earth's climate and the survival of plants, shellfish, coral reefs and other marine life.

Warming oceans are changing Australian reef fish populations      (via sciencedaily.com) 

Shallow reefs and the creatures that inhabit them are changing due to rising ocean temperatures, but these impacts have been obscured by a lack of comprehensive local data. A team of researchers has been tracking changes in the country's reefs for over a decade, and they now describe how they used fine-scale data to illustrate how warming waters impact tropical and temperate reef fish communities differently.

Anthropogenic air pollution more significant than desert dust      (via sciencedaily.com) 

At the beginning of the year, the World Health Organization (WHO) announced that the Middle East ranks among the regions with the worst air quality. There is a common misconception that desert dust is the most significant cause of air pollution from particulate matter in this region, but a new study has shown that more than 90 percent of the particulate matter that is detrimental to health originates from anthropogenic sources. This human-made fine particulate matter differs from the less harmful desert dust particles. Scientists determined this through ship borne measurements and verified it in elaborate modeling calculations. The anthropogenic particles are primarily caused by the production and use of fossil fuels such as oil and gas. They are generally smaller than desert dust and can penetrate deep into the lungs.

Hibernating bears' ability to regulate insulin narrowed down to eight proteins      (via sciencedaily.com) 

Feeding honey to hibernating bears helped researchers find the potential genetic keys to the bears' insulin control, an advance that could ultimately lead to a treatment for human diabetes. Every year, bears gain an enormous amount of weight, then barely move for months, behavior that would spell diabetes in humans, but not for bears whose bodies can turn insulin resistance on and off almost like a switch. In the hunt for the bears' secret, scientists observed thousands of changes in gene expression during hibernation, but now a research team has narrowed that down to eight proteins.
