The strongest evidence yet that global warming has been triggered by human activity has emerged from a major study of rising temperatures in the world’s oceans. The present trend of warmer sea temperatures, which have risen by an average of half a degree Celsius (0.9F) over the past 40 years, can be explained only if greenhouse gas emissions are responsible, new research has revealed. The results are so compelling that they should end controversy about the causes of climate change, one of the scientists who led the study said yesterday. "The debate about whether there is a global warming signal now is over, at least for rational people," said Tim Barnett, of the Scripps Institution of Oceanography in La Jolla, California. "The models got it right. If a politician stands up and says the uncertainty is too great to believe these models, that is no longer tenable."Studies confirm global warming underway

Global warming approaching point of no return...
Climate change: report warns point of no return may be reached in 10 years, leading to droughts, agricultural failure and water shortages. The possibilities include reaching climatic tipping points leading, for example, to the loss of the West Antarctic and Greenland ice sheets (which, between them, could raise sea level more than 10 metres over the space of a few centuries), the shutdown of the thermohaline ocean circulation (and, with it, the Gulf Stream), and the transformation of the planet's forests and soils from a net sink of carbon to a net source of carbon.
