Global warming has been a hotly debated issue since long.?

Answer 1

Ever since the Y2K bug went away. That was the last issue that was going to cause doom and gloom around the planet.

Since that went bust, "global warming" is the next thing that the end of the earthers sees causing the end of days.

This should last for about two more years. Then there will be another scare of the end of mankind when the Mayan calendar shows the end f the Earth.

Answer 2

Research has been ongoing since the 50;s, I think the debate started seriously in the 1970's or '80's. It continues, but the focus of the argument has shifted as the public, industry and government has acknowledged human impacts on our world and is seeking to identify and fund viable solutions.

Answer 3

I just watched a Global Warming program on the Hist. Channel. This same thing has happened before and they say that we are just in a cycle.
They also mentioned that there are a LOT of Green House gasses being generated by China and I was thinking, "Oh, Cr*P." Are we supporting this by being on "tight budgets?" What I mean is, are we selling ourselves out to buy things made in China...I've also seen their training facilities online...

Answer 4

bholeshankar07's answer is right on.

There's a lot less controversy about this is the real world than there is on Yahoo answers:

http://www.worldpublicopinion.org/pipa/articles/home_page/412.php?lb=hmpg1&pnt=412&nid=&id=

And vastly less controversy in the scientific community than you might guess from the few skeptics talked about here:

http://en.wikipedia.org/wiki/Scientific_opinion_on_climate_change
http://www.sciencemag.org/cgi/content/full/306/5702/1686

"There's a better scientific consensus on this [climate change] than on any issue I know... Global warming is almost a no-brainer at this point. You really can't find intelligent, quantitative arguments to make it go away."

Dr. Jerry Mahlman, NOAA

Answer 5

Probably since about 10,000 years ago when the glaciers started to retreat and folks were able to start farming land that had previously been crushed under a mile of ice.

More recently, Thomas Jefferson took measurements that he said indicated warming. There was talk of global warming in the early 1900s. Then there was the 'New Ice Age' scare of the 1970s. Then talk changed back to warming in the 1980s.

Nature has its temperature swings. Humans like to talk about them.

Answer 6

In the 1960's and into the 1970's, the trend lines (and the resulting worries) were the coming of another Ice Age.

So far, the trends have been within 'normal variation', i.e., up or down, but not that damned far up or down.

Note that we have reasonably comparable weather data for only about the last hundred years or so, and that, only in the more 'civilized' areas. The trends are measured in terms of tens of thousands of years. (not enough to go on.)
