Could you help me with the following?
1. "At the same time, there are new scientific studies showing that the earth is in a 20 year long cooling period. "
Could you tell me in which academic journals I can find these studies?
2. These quotes
"In 1998 (left side of the graph below) NASA and the satellite data sources RSS and UAH all agreed quite closely "
"The NASA temperature map for March above shows Alaska temperatures much above "normal", while the UAH map shows Alaska temperatures well below "normal"."
"Nevertheless, the difference between March UAH and GISS global is still 0.5 degrees."
strongly indicate that you were not aware that the NASA and satellite data series have different baselines when you wrote the piece. Is this the case? If not, can you explain how you came to these conclusions?
3. "Using set theory, it is impossible for a subset of size 30 to be near the median and the full set to be in the top three. Absolute worst case would be in the top 15 for the full set."
I think you are confusing your sets. We have (a) the set of NASA global temperatures, we have (b) the set of UAH Southern Hemisphere temperatures, Your observation was that March 08 is near the top of (a) but near the bottom of (b). So what? I propose a more relevant set (c) the set of UAH global temperatures. March 08 is 4th highest in (a) and 13th in (c).
A bit less newsworthy but statistically waaay more legitimate.
4. "Viewing the NASA 250-mile map for March below,"
Its actually the 250Km map isn't it? And NASA prefer a 1200km radius, this being closer to the distance over which temperatures actually correlate.
5 "A second important issue with NASA's presentation is that they use the time period of 1951-1980 as their choice of baseline. This was a well known cold spell, as can be seen in the 1999 version of the NASA US temperature graph below."
It may have been a well-known cold spell in the US, however the NASA baseline is global. Why do you show a US map to make a global point? continental US is maybe 2% of the global surface area. Please explain.
6. "Temperatures dropped enough during that period to trigger concern about the onset of an ice age. Newsweek magazine went so far as to mention a proposed "solution" of spreading soot in the Arctic to melt the polar ice caps. "
1970s Global Cooliing' was largely a media invention. Outside of Newsweek, can you steer me towards the explosion of concern about global cooling in the academic literature of the 1970's that corresponds to the contemporary >1000 papers on AGW? I am thinking of in particular this paper from the American Meteorological Society:
THE MYTH OF THE 1970S GLOBAL COOLING SCIENTIFIC CONSENSUS http://ams.confex.com/ams/pdfpapers/131047.pdf
which found "During the period 1965 through 1979, our literature survey found 7 cooling papers, 19 neutral and 42 warming. In no year were there more global cooling papers than global warming. "
Clutching at straws, me.
