NOTE ON POPULAR POSTS

The reason some popular posts are tagged ‘no title’ is not because they have no title—they all do—but because the old Blogger embedded the title at the top of text, and the new software does not see that. You can see the titles in capitals at the start of each snippet. (It would be nice if Blogger introduced an upgrade program that could fix this little problem.)

CLIMATE-CHANGE EFFECTS UNDERESTIMATED

Charles H. Greene, Professor of Earth and Atmospheric Sciences at Cornell University, one of the authors of 'A Very Inconvenient Truth,' published in the peer-reviewed journal Oceanography (March 2010), says that he and his co-authors conclude that the United Nation's Intergovernmental Panel on Climate Change (IPCC) 2007 Fourth Assessment Report underestimates the potential dangerous effects that man-made climate change will have on society.

'Even if all man-made greenhouse gas emissions were stopped tomorrow and carbon-dioxide levels stabilized at today's concentration, by the end of this century the global average temperature would increase by about 2.4 degrees [Celsius] above pre-industrial levels, which is significantly above the level which scientists and policymakers agree is a threshold for dangerous climate change. Of course, greenhouse gas emissions will not stop tomorrow, so the actual temperature increase will likely be significantly larger, resulting in potentially catastrophic impacts to society unless other steps are taken to reduce the Earth's temperature.'

He also says that thermal inertia in the oceans means that the temperature rise this century will last for a thousand years.
