Acidifying oceans spell bleak marine biological future 'by end of century', Mediterranean research finds
A unique 'natural laboratory' in the Mediterranean Sea is revealing the effects of rising carbon dioxide levels on life in the oceans. The results show a bleak future for marine life as ocean acidity rises, and suggest that similar lowering of ocean pH levels may have been responsible for massive extinctions in the past.
A relatively new type of El Niño, which has its warmest waters in the central-equatorial Pacific Ocean, rather than in the eastern-equatorial Pacific, is becoming more common and progressively stronger, according to a new study by NASA and NOAA.
An unusual substance known as "dry water," which resembles powdered sugar, could provide a new way to absorb and store carbon dioxide, the major greenhouse gas that contributes to global warming, scientists report.
Sea level will likely be 30-70 centimeters higher by 2100 than at the start of the century, even if all but the most aggressive geo-engineering schemes are undertaken to mitigate the effects of global warming and greenhouse gas emissions are stringently controlled, according to new findings by international research group of scientists from England, China and Denmark.
A new study of the High Arctic climate roughly 50 million years ago helps to explain how ancient alligators and giant tortoises were able to thrive on Ellesmere Island well above the Arctic Circle, even as they endured six months of darkness each year.
A new study indicates extinct carnivorous mammals shrank in size during a global warming event that occurred 55 million years ago. The study describes a new species that evolved to half the size of its ancestors during this period of global warming.
Rain drops are fat and snowflakes are fluffy, but why does it matter in terms of predicting severe storms?
Some of the nation's most historic buildings and monuments may be better protected from decay in future, following a development by engineers. Researchers have devised a method of forecasting damage caused by the weather to stone buildings -- including statues, monuments and other historic sites, as well as modern masonry buildings.
The extent of the sea ice in the Arctic will reach its annual minimum in September. Forecasts indicate that it will not be as low as in 2007, the year of the smallest area covered by sea ice since satellites started recording such data. Nevertheless, sea ice physicists are concerned about the long-term equilibrium in the Arctic Ocean.
Emissions of carbon dioxide are causing ocean acidification as well as global warming. Scientists have previously used computer simulations to quantify how curbing of carbon dioxide emissions would mitigate climate impacts. New computer simulations have now examined the likely effects of mitigation scenarios on ocean acidification trends.
