Global Warming - From Inside the Globe
Bill Kendrick writes "The National Post reports that a team of American and Canadian researchers has found evidence of real global warming: the temperature of the Earth's crust is increasing at a remarkable rate. What's really interesting is that heat absorbed by rocks slowly permeates into the earth. By boring holes in the ground, they can tell how hot the earth was years ago, in a 'reading tree rings' fashion."
higher than they were in 1500
Well, duh, ever hear of the Little Ice Age? Circa 1400 to 1800, give or take a half century. Prior to that (about 1000 to 1300), temperatures were warmer than they are today. In England farmers raised wine grapes, the Norse had dairy farms in Greenland.
Climate change happens. Ten thousand years ago a good part of North America (and Europe) was under a mile of ice. I suppose humans take the blame for melting that?
Get a grip.

Also from the article:
"Dr. Beltrami and his colleagues from the University of Michigan found that more than half of the land's heat gain over the past 500 years came during the 20th century, and 30% since 1950."
Try to keep an open mind.
The National Post is not a reliable source of information.
Good thing Slashdot is here to give us unbiased journalism.

Drilling a hole generates heat. Sometimes harder substances generate more heat, sometimes less. While the "heat tree rings" may exist, as seems logical, the act of attempting to observe them corrupts your data.
Using extremely old holes could mitigate this somewhat, but then you have no measure of the geological composition, and therefore thermal properties, of the rock the hole was bored through.
This makes any measurements made of core earth temperature so speculative as to be worthless, except as a very "scientific" expensive way to spread fud. There are quit a few "scientific" methods to measure global warming that are in fact just pseudo scientific pawns in the politically charged arena of environmentalism.
To imagine that we have had no impact on global warming is obviously false. Any argument contrary to what should be painfully obvious to the most casual observer is pure political bullshit.
If voting were effective, it would be illegal by now.
We are not going to destroy the planet by global warming. The earth has endured a great deal of meteorological change and life goes on. The fact is that temperatures are going to change whether we like it or not. I almost think that whether we are making the planet warming by .01 degree is irrelavant because natural changes are probably making it warmer by .5 degrees anyway.
There are better reasons to not cut down forests and to reduce emissions. When people argue global warming, they just pollute the issue and reduce their credibility.

I am devoting my life to the continuation of global warming. I promise I will not rest until the North/East (my home) has Florida like weather conditions year round.
