How can anyone draw a straight line through that mess of randomness? It looks like wishful thinking to me.
No, no, no.
That’s part of the problem - You’re TRYING to draw a straight line through the numbers, and the IPCC (even at this level, when ONLY it’s LEAST aggressive (slowest increasing!) temperature increase in being shown) IS CLAIMING a straight-line increase is DEMANDED by the linear CO2 increase of 1.1 percent each year).
Neither assumption is correct: Temperatures are cyclical, and show a sinusoidal variation with time: Globally, temps rose 1/2 of one degree the 27 years from 1908 through 1935, then fell 1/2 of one degree from 1935 to 1972, then rose 1/2 of one degree from 1972 through 1998.
Since 1998 (an El Nino year - which NONE of the AGW programs can predict!), they have randomly oscillated about the temperature corresponding to 1996-1997: Statistically, as you can see from that part of the chart from 2002 to 2007, they have stayed about the same. Later years indicate a very slight cooling - which is what IS EXPECTED if the next 27 year downward trend has begun.
Yes, CO2 has linearly increased from approximately the early 1940's - exact measurements exist ONLY since the Hawaii lab opened in the early 70's - AS A DELIBERATELY ATTEMPT TO DETERMINE THAT CO2 LEVELS AFFECT CLIMATE.
The ENTIRE purpose of that lab to to "verify" what it was funded for - nonetheless, its data shows a linear increase in CO2 at 1.1 percent year.
Unfortunately for the AGW extremists, temperatures have NOT followed that trend: 27 years they go up, 27 years they go down, 27 years they go up, 7 years they stay steady (and begin to go down) ....
For this, the enviro's DEMAND the destruction of America's economy!
My stock broker until his retirement used to draw straight lines through his stock charts and talk about moving averages. Maybe he still does, I don’t know. These charts look like stock charts, so the analysis was probably done by a stock broker.
