Lots of opinions here, both scientific and lay.
There are those who believe strongly that the temperature of the world is increasing due to pollution and concomitant green house gases and their deleterious effects on the ozone layer (and other impacts).
There are others who believe equally as strongly that the change in temperature is natural and a part of the cyclic nature of global warming and cooling taking place normally over thousands of years.
In spite of both sides claiming absolute proof of their position. I believe the conclulsive case has not yet been established.
All of that said, as stewards of the planet, there is good reason to be sensible in its care and feeding. Arrogance is the biggest threat.
I think it's cyclic solar activity. Most people don't remember but back in the 1930's-1950's people were crying that we were on the verge of a new ice age and that half of the human population was going to be wiped out because there wouldn't be enough fuel to warm people's homes....that we'd be cutting down all the trees and stuff. Then there's be famine & pestilence in the tropical zones because everyone would move toward the equator and there's be too many people there. It was a real scare at that time. Now we're worried about exactly the opposite.
The problem is that in 25-50 years, when it begins to cool of as a natural part of the cycle, the people in power will claim that it's because of THEIR smart thinking in enslaving the world to some type of carbon tax that this disaster was averted, not because we'd crossed into the downside of the cycle. It will be reason for them to continue to suck the life out of the people in order to prevent the boogyman of climate change from coming back or whatever. Once taxes are in place, they don't tend to disappear until the government disappears.
I do not know. I do know, when I watch the TV weather reports, they give the historic highs and lows and the historic highs are back in the 1920s and 1930s.
Also, comparing temperatures with those of the past is almost like the apples and oranges comparison. In the early 1900s, the instrumentation for measuring temperature was not devices which gave digital readiouts to the 1/1000 degree. They were mercury thermometers that had to be viewed by the naked eye with a guess make about a half or fourth degree. Also, the protocols for measuring "official temperatures" have change. A thermometer surrounded by glass and facing west will probably have a higher temperature that one surrounded by concrete and facing east.

I came upon this news that a study showed majority of the Americans do not believe humans caused global warming / climate change. Any idea if this is true? What about the rest of the world, what do we believe?This is...

I'm confused. I've read and heard arguments that global warming is really just part of a natural temperature change process for the earth. I've also read that it's completely man-made? Is it one or both of these? Please...
