If climate change in the form of global warming is caused by human activity and pollution then why from 1947 to 1980 was the world cooler than in the first half of the 20th century when pollution was less? What caused the great global drought of the 1930's?
Did human activity cause that 33-year cooling period that had greenies concluding that pollution had started a new ice age?
Or was it just cyclical?
Myself, I see that fact that sea levels have risen about 400 feet since the last ice age to be an ongoing process and not something that arbitrarily stopped....when?
When did the warming from the last ice age stop?
Ah, that's the question the whole GW thing gets hung up on.
If the post ice age warming is still continuing then how can you say what portion of warming is natural and what portion is induced?
The unspoken assumption being promulgated in our schools and in our media is that 100% of the warming trend is man-made - more specifically, it is Western pollution causing GW while the media and the educational elites are silent about Asian pollution.
Sorry, it's just BS to me.
You may as well say that volcanoes are caused by human activity.
I think that most warming is anthropogenic. I think it's going to be a problem. But we've got lots of other probelems too. Personally, I'm more worried about the fish. I think it's like seven of nine of teh world's fisheries are in decline. If they start to collapse like cod, as some predict may happen in about forty-fifty years, then we're going to have a way bigger problem. And of course, it's really just a matter of time before some kind of airborne ebola-like virus similar to the Spanish Influenza of 1918 comes around again and that will probably wipe out 10-60% of the world. And then there's rogue nations getting nukes. In fifty years, who WON'T have nukes?
I'm not being pessimistic. That's just the nature of things. I do believe, deeply, that we should more respect to the planet than we do now. Not so much because I'm an environmentalist, but because the planet is our life support system.
