FROM OUR previous AUSTRALIAN CLIMATE SCEPTICS blog hidden from the public by the Google SS, This entry was on Saturday, 6 June 2015
The Cartoonist and PhD student (in cognitive psychology) John Cook runs a site misleadingly called Skeptical Science (SS). We prefer to call it UNSkeptical UNScience. It lacks both elements –
Scepticism and Science.
Cook and his conniving cronies have posted a page of, what they call:
Global Warming and Climate Change Myths
Continuing in Cook’s Comical Credentials the page is a catastrophe of chaotic confusion and contrived conclusions.
Let’s examine a few of the flawed feeble failed fallouts.
UNSkeptical UNScience:
“Climate’s changed before” Climate reacts to whatever forces it to change at the time; humans are now the dominant forcing.
This links to a page which erroneously states:
Greenhouse gasses – mainly CO2, but also methane – were involved in most of the climate changes in Earth’s past. When they were reduced, the global climate became colder. When they were increased, the global climate became warmer. When CO2 levels jumped rapidly, the global warming that resulted was highly disruptive and sometimes caused mass extinctions. Humans today are emitting prodigious quantities of CO2, at a rate faster than even the most destructive climate changes in earth’s past.
A recent peer reviewed paper (An Estimate of The Centennial Variability of Global Temperatures: Philip J. Lloyd) rebuts this:
This suggests that while some portion of the temperature change observed in the 20th century was probably caused by greenhouse gases, there is a strong likelihood that the major portion was due to natural variations.
Let’s examine the parts of SS’ flawed fabrication:
Greenhouse gasses – mainly CO2, but also methane – were involved in most of the climate changes in Earth’s past.
In fact, as agreed by ALL climate scientists, in the Earth’s past, temperature increased before rise in atmospheric CO2, (LINK: Jo Nova)
But, in 1999 it became clear that carbon dioxide rose and fell after temperatures did. By 2003, we had better data showing the lag was 800 ± 200 years. CO2 was in the back seat.
When CO2 levels jumped rapidly, the global warming that resulted was highly disruptive
As can be seen, temperature JUMPED before rise in CO2.
Humans today are emitting prodigious quantities of CO2, at a rate faster than even the most destructive climate changes in earth’s past.
That may and probably is true, however, for ~20 years atmospheric CO2 has risen unabated whilst global temperatures have plateaued.
