Scientists have observed for years that the Earth's tropics are widening in connection with complex changes in climate and weather patterns.

More than 500 wildfires were still burning in B.C. in September, with the Yukon, Alberta, Ontario, Quebec, and parts of the Atlantic provinces all experiencing one of the worst fire seasons in history.

Subtropical gyres are huge, sustained currents spanning thousands of kilometers across the Pacific and Atlantic oceans, where very little grows.

University of British Columbia researchers studying the marine food web of the Northeast Pacific Ocean have found that the exposure and accumulation of chemical pollutants, such as polychlorinated biphenyls (PCBs) and organic mercury, will be exacerbated under climate change.

The number of insects species in Connecticut is climbing due to climate change.

Washington University researcher Karen DeMatteo and her scat-sniffing dog Train are on a mission to preserve jaguars, pumas, bush dogs and other carnivores in the forests of Northeastern Argentina.

Committed to addressing the country’s severe air pollution, China is attempting a shift from coal to natural gas and is considering a variety of sources, including domestic and imported gas options as well as creating its own synthetic gas from coal.  

Agriculture that appears to be more eco-friendly but uses more land may actually have greater environmental costs per unit of food than “high-yield” farming that uses less land, a new study has found.

In a first study of its kind study, researchers have found that a common chemical consumers are exposed to several times a day may be altering insulin release. Results of the study, led by scientists at the University of Missouri, indicate that the Food and Drug Administration-approved “safe” daily exposure amount of BPA may be enough to have implications for the development of Type 2 diabetes and other metabolic diseases.

For migrating birds, timing is everything. Showing up at breeding grounds at the right time can ensure a great nesting spot with plenty of food. But recent changes in the conditions and foods that birds depend on makes this timing harder to get right.
