A few problems have come to light with regard to the data used to make claims regarding climate change... particularly claims about global warming. Among the problems identified by Anthony Watts are:
- Poor quality of surface weather stations [nearly 70% of surface stations are placed where the temperature reading can be affected by extraneous heat sources]
- Fewer number of surface weather stations
- Questionable adjustments to data recorded by surface weather stations
- Inconsistencies between surface and satellite temperature monitoring
But what about all of those amphibians that are dying worldwide from global warming? Yeah, about those.... [HT Marc Morano]
ADDENDUM FROM CLIMATE AUDIT
I guess the September temperatures had to go somewhere.Now look closely at the two figures below and see what else you notice.
Left: NASA GISS as of Nov 10, 2008; right - as of Nov 12, 2008.
All of a sudden, a "hot spot" has developed over the Canadian Arctic Islands and the Arctic Ocean north of North America, that wasn't there on Monday (it was gray on Monday). A smaller hot spot also developed over Australia.
I had downloaded the GHCN file on Monday (and saved it). I downloaded the GHCN file once again and checked for stations that had October values today, but not on Monday. All but two were in Australia with the other two also in the SH.
I haven't crosschecked the Australian data but at least there's some new data to support this part of the change. There was no new information from GHCN on the Canadian Arctic Islands. So what accounted for the sudden hot spot in the Canadian Arctic Islands??
Why can Hansen obtain values for October in the Canadian Arctic Islands today when he couldn't on Monday?
Maybe NASA spokesman Schmidt can explain exactly how Hansen "fixed" the problem.
