Face it Barnacle the computer models were wrong.

So why should we pay through the nose for the free air that we breathe to the George Soros of this world.

You do have a link to climate change, I assume?

Which cities? All cities? Some cities?

IF doubling added say 1.5C since before the industrial revolution ( the LIA is before the industrial revolution, CO2 is postulated to have increased since the LIA), then according to theory doubling would take it to about 450ppm. A further doubling to 900ppm would increase temperatures by 3.0C over the pre-industrial period.

Are you now saying CO2 theory is incorrect?

You do realise of course that the latest projections use RCP 8.5 often cited as business-as-usual. But RCP 8.5 is worst-case scenario.

"RCP8.5 gets the most attention. It assumes the fastest population growth (a doubling of Earth’s population to 12 billion), the lowest rate of technology development, slow GDP growth, a massive increase in world poverty, plus high energy use and emissions."

AND? ...

It's not rocket science to put 2 and 2 together. 

CO₂ UP, Temperature UP, Arctic Ice cover DOWN, Ice-Sheets melting, Sea Level UP.

Is there any correlation between CO2 and temperature?

(1).....On a small time scale

(NO)

(11,000 years)

Showing from 200 to 11000 years ago, the subsequent graph is based on ice core data, readily visible in files hosted on the servers of the U.S. National Oceanic and Atmospheric Administration (NOAA):GISP 2 and EPICA Dome C

(2).....On a medium time scale YES???, (450,000 years)

(NO)

, It appears so because of the scale we are zoomed out at.

WARNING !

This is the scale that most global warming sites use to scare the unsuspecting.

Over the past few hundred thousand years of ice core data, a “medium” time scale in this sense, CO2 superficially appears to change in step with temperature if a graph is so zoomed out as to not show sub-millennial time
scales well

A record of temperature and atmospheric CO2 over the past 400,000 years is preserved in the Vostok Ice Core and is shown in the figure on the right.

It can be seen that there have been a series of large fluctuations in temperature (the Ice Ages), accompanied by large changes in atmospheric CO2.

It is thought that these large temperature fluctuations are triggered by Milankovitch cycles - variations in the earth's orbit that change the amount of energy from the sun that reaches us.

However, on their own, these cycles are not enough to explain the changes in temperature.

The full explanation seems to be that the small change in temperature caused by the changing orbit are amplified by natural processes on earth. These cause CO2 to be released from the oceans and the biosphere, causing an increased greenhouse effect.

This is described more fully in this article from the New Scientist (see also Shackleton 2000). For more details on the timing of changes in CO2 and temperature, click on the figure.
