  • If you Google , GREENLAND HOCKEY STICKS , (it's the first link) you can see what the ice really says about Temps. over a much longer time. Not just 1800....

  • Yes, in GREENLAND. But no conclusions can be drawn from a temperature reconstruction in any single site which is not shown to be for some reason representative of the global pattern.

  • Favorite quote... "trees are very common on land." Haha who made this?

  • @strattgatt So they are not common?

  • Isn't is interesting that they don't say who or what organization published the graph. Just that it was published in 1999. Hmmmm.

    I know. I have a graph that was published in 2007 that says we are in the middle of an ice age. Don't ask me for a source or citation.

  • I think it's not graph of 2007 that says we are in the middle of an ice age, but some people interprets it this way.

  • AGW is a SCAM!

  • tree ring data is soo dumb idea...

  • @essayetee

    Glaciologically, ice age implies the presence of extensive ice sheets in the northern and southern hemispheres; by this definition we are still in the ice age that began at the start of the Pleistocene (because the Greenland and Antarctic ice sheets still exist).

  • WHAT COOLING? LOL!!!

    March was the HOTTEST March in the UAH 32 year satellite record.

    UAH (Univ. of Alabama, Huntsville) is run by Dr. Christy, the well known AGW denier.

    Global temperatures for February = 2nd WARMEST February in 32 years.

    Global Temperatures for JANUARY = the HOTTEST January for UAH in 32 years.
