Radical New Hypothesis on the Effect of Greenhouse Gases...

...Al Gore, in his (in)famous movie ‘An Inconvenient Truth’, explained that as the concentration of carbon dioxide increases in the atmosphere, more energy is trapped, warming the planet. This assumption is central to the General Circulation Models (GCMs) and the current consensus on climate change. Michael Hammer, an engineer who specializes in spectroscopy, is sceptical of the GCM but his criticism is more fundamental. In the following paper, using the basic laws of spectroscopy, he shows that a significant portion of energy loss from the Earth’s surface is by direction radiation to space at wavelengths not absorbed by carbon dioxide and other greenhouse gases. This is in direct contrast to the IPCC explanation that there is low radiation from the Earth’s surface to space and potentially high radiation from the atmosphere to space.
Science is a process of getting it wrong and hopefully learning
- on this single issue Michael Hammer and the IPCC can’t both be right.... more from Jennifer Marohasy, here...
...and this startling news too...
... It appears that global cooling recognition may be starting to make headway in the scientific community. We have this Discovery/MSNBC article about a NOAA scientist titled “Warming might be on hold, study finds
“It is possible that a fraction of the most recent rapid warming since the 1970’s was due to a free variation in climate,” Isaac Held of the National Oceanic and Atmospheric Administration in Princeton, New Jersey wrote in an email to Discovery News. “Suggesting that the warming might possibly slow down or even stagnate for a few years before rapid warming commences again.”
And Swanson thinks the trend could continue for up to 30 years...more, here... and here...
...Everybody knows it hasn’t been getting warmer, but it has been getting colder. So, are the climate models which predicted warmer and not colder wrong?
Well, Kyle Swanson of the University of Wisconsin-Milwaukee says, “temperatures should have gone up”. But nobody told the temperatures. Isaac Held of the National Oceanic and Atmospheric Administration in Princeton said, “warming might possibly slow down or even stagnate for a few years before rapid warming commences again.” Not to worry, “we’ll have explosive warming” Held says.
In other words, the models have been wrong up to now, they are still wrong, but we still believe them....
