@ seno, Do you have a reliable, verifiable source for that stat?
There are two camps here. Believers and doubters. Both, to an extent not worth differentiating, believe we should use our energy more efficiently, cut down on the crap we are spouting into the atmosphere and generally treat the planet a lot more kindly than we do at the moment.
I recycle. I've quadrupled the insulation in the loft. We're getting cavity wall insulation. We replaced our knackered boiler with a super-efficient condenser and added thermostatic valves to all our radiators. I drive a small, efficient car. We buy most of our food from local sources etc. I'm doing my bit. Whether we're causing the world to get warmer is, to my mind, utterly irrelevant when it comes to choosing to use energy more efficiently and generating it in ways that don't pump shit into the air.
But NOBODY, surely, can deny that we are, at the absolute minimum, being exaggerated to. There were the NASA temperature figures for last October that showed it was the warmest on record - until someone mentioned how cold it had been in October. At which point they admitted the figures had been copied and pasted from September. There is the nonsense with the selection of the tree samples from Siberia. There is the loss of the data from the University of Anglia etc. etc. etc.
Time and time and time again we are told the debate is over (always an alarm ringer in my head), "scientists" are in agreement and yet I have still NEVER seen any evidence that compels me to believe that the warming seen in the last 100 years is statistically significant when compared to all other similar periods for the last few thousand years.
Now, I'm not saying this would be an easy thing to prove. Reliable data for the last few thousand years is incredibly difficult to produce. Even reliable data for the last few decades seems hard enough. And yet we are told it's been done, it's conclusive but we don't need to see it because "scientists" have seen it and they "are all in agreement".
Something is rotten in the state of Denmark.
