19 October 2010
I was on a conference call with some climate experts yesterday when someone mentioned this graph from NOAA. Every decade from the 1950’s through 2000-2010 was warmer than the decade before it.
NOAA also has released the September temperature anomalies. Even with the strong La Nina of cool waters in the Pacific, it was the 8th warmest on record. January through September is now tied for the warmest year on record as well.
If someone tells you this is being caused by the sun, you can reply that the sun has been unusually quiet this year. It only recently began to get active as the next solar cycle starts.
The graph of the decadal temperatures smooths out the natural cycles like El Nino and the Pacific Decadal Oscillation. It also smooths out the slight rise and fall in the global temperatures from the solar cycle.
Oh, there is this:
It’s called the Keeling Curve in honor of Charles Keeling who started the carbon dioxide measurements at Mauna Loa. The reason 97.5%* of climate scientists are sure the planet is warming, and that it’s the greenhouse gases that are doing it is simply this.
Every other realistic possibility has been ruled out. Yes, there are natural cycles but the greenhouse gases will warm the Earth no matter
As Neil DeGrasse Tyson says: The laws of physics are real. Everything else is just politics.
* That number is based on peer reviewed science
