Brett Smith for redOrbit.com - Your Universe Online According to University of Hawaii at Manoa oceanographer Richard Zeebe, future warming due to the current burning of fossil fuels will cause the Earth's global temperatures to rise longer than expected. In his report, which was published in Proceedings of the National Academy of Sciences, Zeebe looked at the long-term climate effects of today's human activity thousands of years into the Earth's future. "When we talk about climate...

There is little doubt among scientists now that human carbon dioxide emissions are warming the planet. Another problem of rising atmospheric carbon dioxide (CO2) is that CO2 is being absorbed by the oceans, which increases seawater acidity (lowers the seawater pH). This process, termed 'ocean acidification', has received growing scientific and public interest because it threatens certain groups of marine organisms, including corals. Only recently have researchers realized that man-made carbon...

Scientists say long before mankind began burning fossil fuels, there was an eons-long balance between carbon dioxide emissions and Earth's ability to absorb them. But now the planet is having trouble keeping up.A report in the journal Nature Geoscience, is based on ancient Antarctic ice bubbles that contain air samples going back 610,000 years.For the last 25 years, climate scientists have suggested that our planet's temperature and the level of carbon dioxide in the atmosphere have been...
