Climate (Part 3 from March 2008)

Sahara Became Dry Slowly, Not Abruptly

Jennifer Marohasey - May 9, 2008 - 11:24pm
The once-green Sahara turned to desert over thousands of years rather than in an abrupt shift as previously believed, according to a study on Thursday that may help understanding of future climate changes. And there are now signs of a tiny shift back towards greener conditions in parts of the Sahara, apparently because of global warming, said the lead author of the report about the desert's history published in the journal Science.

The Starck Truth about The Great Barrier Reef

Jennifer Marohasey - May 9, 2008 - 5:37am

Walter Starck has an excellent 4 page rebuttal of a greenhouse doom and gloom article by Charlie Vernon over at On Line Opinion entitled, 'The plight of the Great Barrier Reef:' "By 2050 the Great Barrier Reef will be unrecognisable. Bacterial slime, largely devoid of life, will be everywhere." Dr J.E.N. (Charlie) Veron is Former Chief Scientist at the Australian Institute of Marine Science and an author based in Townsville Queensland. Read more »

Measuring the Surface Air Temperature (Part 2)

Jennifer Marohasey - May 8, 2008 - 8:48pm

In part 1 of this series ‘Measuring the Surface Air Temperature’ I wrote that James Hansen of NASA’s Goddard Space Institute explains that it is not easy to measure surface air temperature particularly in the presence of vegetation because the temperature above the vegetation may be very different from the temperature below the vegetation.

Cyclone: Mangrove Loss Left Burma Exposed, but Gore Blames Global Warming

Jennifer Marohasey - May 7, 2008 - 8:53am

Destruction of mangrove forests in Burma left coastal areas exposed to the devastating force of the weekend's cyclone, a top politician suggests.

ASEAN secretary-general Surin Pitsuwan said coastal developments had resulted in mangroves, which act as a natural defence against storms, being lost.

Sea Ice Update: Unprecedented SH High, Rapid NH Recovery

Jennifer Marohasey - May 6, 2008 - 3:12am

There won't be much, if any, coverage in the media about the unprecedented high in the Southern Hemisphere sea ice anomaly, so a self-explanatory graphic is posted below of the 1979 to present anomaly from the 1979 to 2000 mean:

Cyclone Bandwagon Gains Another Passenger

Jennifer Marohasey - May 9, 2008 - 8:35pm
A TOP Indian advocacy group that monitors climate change in south Asia warned last night that the Nargis cyclone that devastated Burma was "a sign of things to come", as climate change caused extreme weather to increase in intensity. "Nargis is a sign of things to come. Last year, Bangladesh was devastated by the tropical cyclone Sidr," CSE director Sunita Narain said in a statement. "The victims of these cyclones are climate change victims and their plight should remind the rich world that it is doing too little to contain its greenhouse gas emissions." Read more »

New Study: Climate Models Overheat Antarctica

Jennifer Marohasey - May 8, 2008 - 11:39pm

BOULDER - Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at the National Center for Atmospheric Research (NCAR) and Ohio State University. The study can help scientists improve computer models and determine if Earth's southernmost continent will warm significantly this century, a major research question because of Antarctica's potential impact on global sea-level rise.

Latest Global Warming Scares: 'Grolar Bears' and CO2 Kills Koalas

Jennifer Marohasey - May 8, 2008 - 7:39pm

BOFFINS fear Arctic ice melting could see the rise of a polar bear and grizzly bear hybrid - dubbed the 'grolar bear.' The effects of climate change means the hybrid bears could become more common as their habitats increasingly overlap due to global warning. ...And he delivered a stark warning of what the future holds. He believes that by THIS summer there could be no ice at the North Pole. ...And Dr Divoky had a message for climate change sceptics, saying: "Having a polar bear show up in your front yard is one of the more compelling pieces of evidence that climate change is real."

Measuring the Surface Air Temperature (Part 1)

Jennifer Marohasey - May 6, 2008 - 11:40am

The orthodoxy has been that as a consequence of greenhouse gas emissions global temperatures will continue to increase. But what is really meant by global temperatures? According to James Hansen from NASA's Goddard Institute for Space Studies even defining surface air temperature is not easy: Read more »

William Connolley at Wikipedia - by Lawrence Solomon

Jennifer Marohasey - May 5, 2008 - 12:07pm

At Wikipedia, one man engineers the debate on global warming, and shapes it to his views:

Next to Al Gore, William Connolley may be the world's most influential person in the global warming debate. He has a PhD in mathematics and worked as a climate modeller, but those accomplishments don't explain his influence -- PhDs are not uncommon and, in any case, he comes from the mid-level ranks in the British Antarctic Survey, the agency for which he worked until recently.
