Researchers visited Christmas Island, the world’s largest coral atoll, to measure the effects of El Nino. Eighty percent of the coral is dead, they report. Corals are communities of animals that have tiny photosynthetic algae living inside them in a mutually beneficial relationship. Corals are very temperature-sensitive. A rise of just 1-1.5 degrees Celsius can stress coral enough to evict … Read More
New heat wave formula can help public health agencies prepare for extreme temperatures
Extreme heat can pose several health risks, especially during sustained periods of high temperatures. However, a uniform definition of a heat wave doesn’t exist. As a result, public health agencies may be unsure of when to activate heat alerts, cooling centers and other protective measures. A University of Missouri School of Medicine researcher has developed a uniform definition of a … Read More

Assessing the impact of human-induced climate change
Researchers at the Lawrence Berkeley National Laboratory and Potsdam Institute for Climate Impact Research develop and apply new method to determine whether specific climate impacts can be traced to human-caused emissions.
Greenhouse gas can escape the deep ocean in surprising way
Carbon dioxide can emerge from the deep ocean in a surprising way — a new piece of the global carbon “puzzle” that researchers must solve to fully understand major issues like climate change.
Air pollution: a dark cloud of filth poisons the world’s cities
The number of annual deaths caused by pollution around the world is now greater than malaria and HIV combined, according to a recent study, with scientists warning that fatalities could reach 6 million a year by 2050.
