Climate change is already costing lives and dollars : Comments

By Barrie Pittock and Andrew Glikson, published 22/12/2009

Climate change impacts and costs are not merely something for future generations to bear, they are being experienced now.

Now they are all in climategate damage control,spinning the planet off it's axis with even more distortions and falsehoods.

Read basic text books in climate science and re-aquaint with the laws of physics and chemistry instead of raising conspiracy theories against the world's premier climate science organizations, including NASA/GISS, NSIDC, Hadley-Met, Tyndall, Potsdam, CSIRO, BOM, and thousands of peer-reviewed papers in scientific journals, not to mention direct observations around the globe of melting ice sheets and mountain glaciers, trippling sea level rise rates, intensifying hurricanes and long-term to semi-permanent droughts caused by migration of climate zones and the mid-latitude high pressure ridges toward the poles.

Since the industrial revolution in the mid-18th century, combustion of fossil fuel resulted in the emission of more than 320 billion tons of carbon (BtC) in the form of carbon dioxide (CO2). This is more than half the pre-industrial carbon content of the atmosphere of 590 BtC. About 200 BtC stayed in the atmosphere, raising CO2 concentration from 280 parts per million (ppm) to the current level of 388 ppm. When the effects of the gas methane (CH4) are included the total greenhouse effect (CO2-e), the total rise of greenhouse gases is equivalent to 460 ppm CO2.

Consistent with the basic laws of physics and chemistry, experimental evidence and direct observations in nature, greenhouse gases (water vapour [H2O], carbon dioxide [CO2], methane [CH4], Nitric oxide [N2O], ozone [O3] and other gases) possess heat-absorbing and heat-emitting capacity. This characteristic arises from the translation of heat into kinetic energy (internal vibration of gas molecules) and, conversely, of kinetic energy to heat. The concentration of greenhouse molecules in the atmosphere thus acts as a ‘warm blanket’ without which the mean temperature of the Earth surface would have been about 30oC lower than the present mean level of about 14oC.

Andy1 prefers conspiracy theories against skeptical people and people who are in the "don't know" category.

One of the premier climate organizations have just just seriously damaged not just themselves but that entire niche of science.

Give it up Andy1, after your attempt to prop up desmogblog as a reputable objective organization and flog a book, you certainly lack any credibility now to point the bone at any one else.

Anyone would think you're making a buck out of this Andy1?

Are you being paid in relation to AGW? Are you part of a group, PR group are you Andrew Glikson? Propping up your puff piece? If you are you should really state that, but of course, honesty is not expected with AGW believers, is it?

Odo your comment, just posted, is in great contrast to that by Andy1.
Andy 1 has appealed for some reading to be done. Your response was almost exclusively vituperation against his character; sure to be applauded by people of like mind to your own. However, any sane person reading this blogsite and wanting to be informed would find greater appeal in Andy1’s comment. However rational this statement of mine might be, I doubt if it will be well received.

Rapid climate change is happening in the present time, as manifested by polar ice melt, sea level rise, extensive droughts in Australia, China, Argentina and the US, extreme weather events, and acidification of the oceans. Climate scientists have projected the current trends since the 1980s, including authorities such as Professor James Hansen and his group (NASA), Professor Wally Broecker (Columbia University), Dr Barrie Pittock, Dr Graeme Pearman and Dr Ian Enting (CSIRO). The atmospheric energy rise exerted by the well-mixed greenhouse gases, mainly CO2 and methane, is consistent with the basic laws of physics and chemistry and with calculations and observations in nature and the laboratory. Measurements of solar radiation and cosmic rays rule out these factors as drivers of climate change since the mid-20th century. The fast rise in carbon emissions (41% since 1990) is driving global temperature, ice melt rates and sea levels. The zigzag nature of temperature rise since the mid-1970s results from the combination of the warming trend with (A) the natural El-Nino – La-Nina cycle (ENSO – El Nino Southern Oscillation) driven by ocean current pulsations, and (B) the 11 years-long sun spot cycle. This results in an overall rising zigzag pattern of temperature change. As temperature increase, reflecting the level of energy in the atmosphere-ocean-land system, the amplitude of climate variability and the likelihood of extreme weather events increase. This may involve periods of relative stability followed by abrupt tipping points, namely, sharp shifts in the state of the atmosphere.

Dear Barrie and Andrew, since the IPCC and their contributing authors are the only authorized international franchise on AGW, any science, from whatever source that is not submitted and accepted by the IPCC it is just more research and opinion, unofficial.

It seems like the two of you have been on the Christmas “tipple” a little early. Why don’t the two of you have a good festive season, chill out and come back in the New Year, then ask two questions of the IPCC. Please post any answers obtained.

Q1, please provide any evidence whatsoever, of global warming and Q2, if there is evidence, please explain any links to atmospheric carbon.

I fully accept that you will have to put your questions on hold until the conclusion of the various investigations taking place. That’s OK; it appears we can wait after all.

Jolly Hockey Sticks chaps.
