From providing habitat to food sources, to regulating water cycles, plants are the backbone of all life on Earth. What often goes unrecognized, but is equally as important are plants’ roles as climate controllers.
According to a new study conducted by (more…)

Wildlife may play a more important role in the global carbon cycle than researchers have previously given it credit for, according to a study from an international group of scientists.
Although models generally include carbon cycling by plants and microbes, they often ignore the ways (more…)

The rise in surface air temperatures in southern Africa over the past two decades may be due to the loss of upper atmospheric ozone over Antarctica, reports a paper published online this week in Nature Geoscience. The findings suggest that the closure of the Antarctic ozone hole could lead to a reduction in surface air temperatures in (more…)

Ammonia emissions from agricultural fertilizers are threatening sensitive ecosystems in U.S. national parks, a study led by Harvard researchers has found.
Thirty-eight national parks are seeing nitrogen deposition levels at or above the threshold for (more…)

Climate change could significantly transform up to 86 percent of the planet’s land ecosystems under worst-case global warming scenarios, according to researchers at Germany’s Potsdam Institute for Climate Impact Research. That estimate is based on a 4 to 5 degree C temperature increase by the year 2100 — a scenario that is plausible given many (more…)

Recently, I had reason to check out what some of the suppliers of industrial HVAC products in the UK are up to, for example, Heaters Wholesale – England’s largest independent distributor of heating products. I was impressed that the controllers they use maximize fuel savings through what they call “self-learning optimization”; the device varies the heating start-up (more…)

Climate models are evolving, and are getting more accurate, but they are still incomplete. Our atmosphere is very complex, and there are factors that even current models don’t address, or address with an in-complete knowledge of the physical processes involved. This leads to inaccuracies that create uncertainty in the results of climatic projections. (more…)

Saying it is 95 percent certain that humans have caused most of the global warming of the last half-century, scientists with the Intergovernmental Panel on Climate Change (IPCC) warned today that the world can afford to burn about 1 trillion more tons of carbon before facing extreme climate change. (more…)

Gains in air quality that would come from reducing greenhouse gas emissions could save up to three million lives per year by 2100, according to U.S. researchers.
Their findings, published in Nature Climate Change, come ahead of an important interim report by the Intergovernmental Panel (more…)

The U.S. Environmental Protection Agency will for the first time begin regulating carbon dioxide emissions from new coal- and natural gas-fired power plant sunder the Clean Air Act, EPA Administrator Gina McCarthy announced. Speaking in Washington, McCarthy said, “Climate change is real, human activities are fueling that change, and (more…)
