Here's a nice little chart for the boy who cried "wolf". <img src="http://www.edgeblog.net/wp-content/uploads/2009/10/globaltempchart.gif">
"It's global cooling that man needs to worry about. We are due for another ice age to start any time and the world won't support billions of people when that happens. If the earth goes snow-ball again, no one is going to survive. Scientists believe the change occurs over just a matter of a couple decades once it starts so don't think there are thousands of years to prepare. If only we really could warm the planet." Please explain how this chart supports your claim, made previously in this very thread.
could you show us the proof about this hockey graph being valid. I recently read a link on et saying the data shows no such thing. It was just a specious conclusion.
how do you know that Co2 would not be accumulating, just like it did in response to previous warming cycles?
He can't. The math used to fabricate the graph is beyond him. The Hockey Stick has been thoroughly discredited. Only the most fervent fanatics of the Church of the Global Warmists still cling to that graph.
The following sources prove the hockey stick is indeed still valid. It's sad how many of you don't know it. It's sad how brainwashed by right wing rhetoric you are, or are just plain science-dumb. Your grandchildren will wonder how you could have been so stupid as they battle the results of our pollution. Yeah 98% of the climate scientists are wrong and have no ethical or intellectual integrity. Sure. http://green.blogs.nytimes.com/2010/09/23/the-hockey-stick-lives/ http://www.scientificamerican.com/article.cfm?id=still-hotter-than-ever Details of the claims and counterclaims involve lengthy and arcane statistical arguments, so let's skip straight to the 2006 report of the US National Academy of Science (pdf). The academy was asked by Congress to assess the validity of temperature reconstructions, including the hockey stick. "Array of evidence" The report states: "The basic conclusion of Mann et al. (1998, 1999) was that the late 20th century warmth in the Northern Hemisphere was unprecedented during at least the last 1000 years. This conclusion has subsequently been supported by an array of evidence that includes both additional large-scale surface temperature reconstructions and pronounced changes in a variety of local proxy indicators, such as melting on ice caps and the retreat of glaciers around the world". Most researchers would agree that while the original hockey stick can - and has - been improved in a number of ways, it was not far off the mark. Most later temperature reconstructions fall within the error bars of the original hockey stick. Some show far more variability leading up to the 20th century than the hockey stick, but none suggest that it has been warmer at any time in the past 1000 years than in the last part of the 20th century. http://www.newscientist.com/article...hockey-stick-graph-has-been-proven-wrong.html
So are these "scientists" trying to argue that it's not warming that's alarming, but the rate of warming!? Crazy, who's afraid of "rates"? ; )
