(OP source)Now the question is how has warming slowed and how much influence does human activity have?
"But if we don't understand what is natural, I don't think we can say much about what the humans are doing. So our interest is to understand -- first the natural variability of climate -- and then take it from there. So we were very excited when we realized a lot of changes in the past century from warmer to cooler and then back to warmer were all natural," Tsonis said.
IÂ’d say the OP is exaggerating what the study says. The guy isnÂ’t claiming all changes are natural, heÂ’s saying weÂ’d need to understand natural patterns before assessing human impact.
Climate is indeed complex. While global warming may imply an average temperature increase, that doesnÂ’t mean it would increase uniformly in all areas. The standard deviation would be expected to increase as well, i.e. more temperature extremes and stormy weather depending upon the area. How do we control for natural cycles when we donÂ’t even understand them? We canÂ’t. Perhaps a manmade process is being temporarily offset by a natural process.
It does, however, seem quite reasonable that releasing the CO2 locked in fossil fuels being released would increase the temperature. After all, the world was a lot warmer during the time when that carbon was in the atmosphere. Of course there were many factors involved in that.
For policy purposes, though, itÂ’s somewhat moot. We want to get off of foreign oil. We want cleaner air. So either way alternative energy (including nuclear) should be aggressively pursued. If coal really can be clean, then sure we can do that too. We donÂ’t need to wait for a verdict on global warming to act prophylactically as it has other purposes.
I think it will be a moot point anyway the way the world's pressure cooker is heating up. Say man made global warming is true....
what would a mushroom cloud do to global warming? seriously.
You're far too pessimistic. I don't think the world is in that bad shape.
You're talking about my grandkids.....which is about 30 years away, roughly.
the world is a lot more screwed up than it was in 1979.
How do you figure? Yesterday the Commies were supposed to blow us away, now it's supposed to be the Islamofascists. Same shit, different assholes. Time to focus on countermeasures to nukes.
