Earth is having a bad acid trip, study finds
Earth may be overdosing on acid - not the "turn on, tune in, drop out" kind, but the "kill fish, kill coral, kill crops" kind. And it's shaping up to be a very bad trip.
Shells slim down with CO2
Marine algae that turn carbon dissolved in seawater into shell will produce thinner and thinner shells as carbon dioxide levels increase.
Scientists study effects of rising carbon dioxide on rangelands
Rising carbon dioxide (CO2) levels can reverse the drying effects of predicted higher temperatures on semi-arid rangelands, according to a study published today in the scientific journal Nature by a team of U.S. Departmen ...
How hot did Earth get in the past? Scientists uncover new information
The question seems simple enough: What happens to the Earth's temperature when atmospheric carbon dioxide levels increase? The answer is elusive. However, clues are hidden in the fossil record. A new study ...
Curb soot and smog to keep Earth cool, says UN
Sharply reducing emissions of soot and smog could play a critical role in preventing Earth from overheating, according to a UN report released on Tuesday.
CO2 makes life difficult for algae
The acidification of the world's oceans could have major consequences for the marine environment. New research shows that coccoliths, which are an important part of the marine environment, dissolve when seawater acidifies.
Arctic studies show dire effect of ocean acidity
The icy Arctic waters around Norway's archipelago of Svalbard may seem pristine and clear, but like the rest of the world's oceans they are facing the threat of growing acidity.
Scientists identify freezing times for Cretaceous dinosaurs
Scientists studying fossils and minerals from Arctic Svalbard, in Norway, have discovered evidence that the ‘greenhouse’ climate of the Cretaceous period was punctuated by a sudden drop in global temperatures.
Governments 'misjudging' scale of CO2 emissions
Policy makers in Europe and United States are markedly underestimating the changes needed to mitigate CO2 emission required to prevent dangerous climate change because they work in 'silos', according to pioneering research. ...
USF Study Shows First Direct Evidence of Ocean Acidification
(PhysOrg.com) -- Seawater in a vast and deep section of the northeastern Pacific Ocean shows signs of increased acidity brought on by manmade carbon dioxide in the atmosphere -- a phenomenon that carries with ...
Climate scientists underwhelmed by Copenhagen Accord
Top climate scientists said Saturday that the eleventh-hour political deal hammered out at UN talks in Copenhagen falls perilously short of what is needed to stave off catastrophic global warming.
Koalas, penguins at risk of extinction: study
Climate change threatens the survival of dozens of animal species from the emperor penguin to Australian koalas, according to a report released Monday at the UN climate summit.
Long-Term Effects of Carbon Dioxide on Plants Studied
(PhysOrg.com) -- Long-term, open-top chamber studies of how rising carbon dioxide (CO2) could affect crops, forests, and pastures reveal a wide range of impacts, according to Agricultural Research Service ...
Elevated CO2 levels may mitigate losses of biodiversity from nitrogen pollution
Rising levels of carbon dioxide may overheat the planet and cause other environmental problems, but fears that rising CO2 levels could directly reduce plant biodiversity can be allayed, according to a new study by a University ...
