We’ re marching for Science, Yippee!
Obama is gone. We are free
to explore what is true.
No more models will do.
The Climate has changed, totally!
The Climate doomsayers are out in force are out in force again. Here is a sign
So, let’s see what facts are in.
CO2 is a strong greenhouse gas, second only to water vapor in affecting the climate on earth. If CO2 were to double from pre-industrial times, which it will have done in 50 years or so, global temperatures on earth will increase about 0.9 degree Celsius from pre-industrial times, if that was the only factor affecting the greenhouse effect. This corresponds to a radiative forcing of 4.9 W/m2. But water vapor is a stronger greenhouse gas than CO2, and, this is important, they are not orthogonal as defined by chemometrics, that means, the responses from water vapor and CO2 are not independent, and they are only partly additive. Check this figure: The bottom line is the absorption of water vapor, the green line is for CO2. The area of interest is between 8 and 20 microns, where CO2 absorbs more than H20 and is at the maximum of outgoing black body emission at 0F. The CO2 concentration is on the order of 400 ppm, the average global H2O concentration at surface level is around 12,500 ppm. Since both H2O and CO2 absorb in the same area, if water vapor concentration is more than 30 times higher, the CO2 con- centration doesn’t matter, it is all absorbed by H2O, and this is the reason there is no hotspot in the equatorial troposphere. All climate models predict there must be one, so there must be something seriously wrong with all climate models.
What does IPCC do with this evidence?
IPCC ignores it, and claim the models are still correct.
This is not science, but politically correct science denial.
We are now in a nineteen year Climate “pause”, where increasing cloud cover with its strong negative feedback cancels out the potential temperature rise of rising CO2.
We are in the bog-building phase of the inter-glacial period, and the long term temperature trend is down, rising CO2 will delay the onset of the next ice age by maybe 2000 years.
The real debate has just started, and this time, let us talk real science, verified by observations, not fear-mongering political statements.
