David Appell tells of his correspondence with Tim Ball
The other day I challenged Tim Ball’s assertion that “the world is cooling.” I showed temperatures plots for the last several years, and of course it depends on how you want to define “climate” — do you consider it the last one year of temperatures, the last five years, the last ten years, etc.? Of course, none is inherently correct — there is no fundamental definition — but all are meaningful to consider.
As I noted, all moving averages over the last 25 years are increasing, though there is perhaps a small flattening in the last few months of the 5-yr moving average, which frankly doesn’t seem all that important.
I wrote Tim Ball and challenged him on these facts, and got back some answers that frankly don’t make a lot of sense to me.
The most remarkable of which is:
I am in agreement with Sherwood and Craig Idso that there is no warming evident in the record since 1930.
But last time around it was
Yes, it warmed from 1680 up to 1940, but since 1940 it’s been cooling down. The evidence for warming is because of distorted records. The satellite data, for example, shows cooling.
1940, 1930, the number seems to change as often as the number of years he reckons he was a professor.
