#1 ...after enjoying relatively stable temperatures for 2,000 year...

This is just ignores the Little Ice Age around the start of the Dark Ages and the relapse around 1400 to 1850?

Or are they using two data points like in 'if your head is in the refrig and ass in the stove, you're relatively comfortable'?

#2 This is hilarious. If you read the actual press release, you see that it says almost none of this.

The press release says that the last 25 years of the 20th century were warmer than any comparable period (i.e., any other 25 years) of the last four centuries. Before then they can't say, because there are not enough "proxy" measurements available.

The Yahoo article says:

Their conclusions were meant to address, and they lent credibility to, a well-known graphic among climate researchers a "hockey-stick" chart that climate scientists Michael Mann, Raymond Bradley and Malcolm Hughes created in the late 1990s to show the Northern Hemisphere was the warmest it has been in 2,000 years.

The press release says the "hockey stick" chart is "plausible". That's as enthusiastic as it gets. It goes on to say:

The Research Council committee...had less confidence that the warming was unprecedented prior to 1600...even less confidence can be placed in the Mann team's conclusions about the 1990s, and 1998 in particular.

The NAS didn't ignore the medieval warm period; Yahoo did. The press release is not exactly difficult to understand. The "2000 years" thing is just bull.

#3 The "2000 years" thing is just bull.
Especially since Gallileo didn't invent a crude water thermometer until 1593. Fahrenheit invented the mercury thermometer in 1714.

#4 I just bought a shiny new thermometer and put it on my desk for the first time today. I can say with all confidence this is the hottest day I've recorded at my desk. Also the coldest. If Bush had only signed Kyoto...

#5 So what's the trend, Sea? How does it further validate swelling concerns about the irrepairable damage the Anti-Gorebots are continuing to do to our fragile ecosystem?

#6 Especially since Gallileo didn't invent a crude water thermometer until 1593.

That part's not entirely bull. That's what the whole "proxy measurement" thing's about: we don't have actual temperature measurement back much more than a century, so we have to use "proxy" measurements -- tree rings or summat. The press release does state that it's possible that environmental factors might have changed so that the proxies don't map to temperature the way they do today. Just one of those little caveats Yahoo overlooked.

#7 Is there anything nicer than a new thermometer?
