Scientists having researched and found that the icebergs and icecaps have been melting. Now the Antarctic is full of water not just ice. This is the prof tha global warming is taking place. Global warming is when there is a hole in the oंzone layer . When there is a hole , the ultra violet rays and extra other sun rays are getting in the earth . Hence the earth gets warmer and warmer so the ice starts melting.

First of all, you would have to give a clearer definition to what is Global Warming. Is it the 0.7 to 0.8 degree rise in earth's temperature coming out of the Little Ice Age around 1650 to 1990? This is what was confirmed as best knowledge and expressed in the 1990 IPCC report, page 202, section 7. Is there anything dangerous in that? Is this what the trillion dollars of money spent on AGW is all about? Is 0.8 degree rise in temperature anything to worry about? Is it natural or is it artificially induce by man? You would have to scientifically answer those honest questions first. As to date, no AGW theorist has. But it is for their benefit to have the issue remain cloudy.

You just wont give up on this ridiculous idea that AGW isn't real, even in the face of real time temperature measurements showing the warmest 17 years on record have come in the last 18 years.

Rising of water and changing of temperatures. I take Geosystems at school

The chemistry of CO2 tells us how it will cause the planet to warm. That is your primary evidence in favor. Evidence that it is not other factors is largely missing. The hockey stick was supposed to show such evidence, but this is discredited. The lack of such evidence is why Kevin Trenberth argues that the null hypothesis should be changed in favor of CO2 as the cause. Then it is not on climate scientists to establish that it is not natural variation, but on skeptics to prove Trenberth wrong.

I have stated this time and time again. Look at spectral frequencies.

The only hard (empirical) evidence that that the globe is COOLING --- not warming. http://www.woodfortrees.org/plot/rss/from:1998/to/plot/rss/from:1998/to/trend -----------------------

it's not a cycle anymore than increasing CO2 to 400PPM is a cycle or having 7 billion people is a cycle. one of less talked about effect is stratospheric cooling. we can pretty well eliminate the cycles as most are short term while there is a underlying long term warming in the last 150 years.

Gary doesn't seem concerned at all that the past has continued to cool over time in a inescapably obvious way to exaggerate the present. Little children will eventually learn that someone was lying to them about Santa Claus (and sorry if I just ruined your Christmas CR) but alarmists never learn. They keep waiting for the quarter to be left under their pillow at night and simply become more angry at those suggesting that tooth fairy will never arrive. I appreciated Jeff Eng's answer. It was concise and hard to argue with IMO.
