The fact that has occurred in the past serves as evidence that it could be happening now, not against it.
If you mean why is it believed that there is a human element, that us because some models indicate that the current change in CO2 concentration is far greater than others in recent geologic history.
Not at all. By giving space to the opposing side, that variously claims that global warming is not happening, is happening but is not a problem, or is happening and is a problem but we have no power to stop it, the news media is unintentionally playing down the problem of global warming. This is a concern for scientists, who say global warming is real but can be stopped if we take decisive action before it is too late.
I wonder how we can mitigate the effects of global warming before irreversible damage is done to our planet. I am curious about the role of technology and innovation in finding solutions to reduce greenhouse gas emissions and slow down climate change.
Why is it more of a problem now than it was before the industrial revolution? global warming
The albedo effect, characterised by changes in the reflection and absorption of sunlight, does play a small role in global warming, but requires global warming to be underway before it can play that part. As the world warms, ice caps and sea ice melt. Ice reflects much of the sun's energy back into space, but when the ice disappears the open sea and land absorb much of the sun's energy, becoming warmer. This accelerates global warming.
No because the Kyoto protocol assumes human beings are responsible for global warming. This is unlikely to be the case because the earth has gone through numerous cycles of warming and cooling going back long before human beings were a significant presence on this planet. Ever heard of the Ice Ages? There were several. Global warming and cooling are a function of solar activity and people can't control the sun.
The world deals with ozone depletion before global warming. It is because ozone depletion is much fatal.
Well I think that global warming is really scary for people. Because people can't really do things. Do to global warming so they have to try and stop it before it gets worse.Mostly hysterical.
Thicker than now
most likely not. just because global warming is occurring does not mean that it caused the flood. in the past flood aways happen, not just because of global warming. in my school before the charts were way up, it flooded, not because of global warming, but because the school was built on a filled up marsh.
Jeopardy had a Global Warming category on February 14 2001 in the double Jeopardy round (See related link) and questions with Global Warming in the clue or answer before and after that date see related link
Global warming will not affect the tides, which are caused by the gravitational pull of the moon. There will be more water in the oceans, of course, so a high tide will be higher than before.

Global warming doesnt exist you idiot hippies!
The continent itself will not be affected by global warming. However, the ice sheet that covers 98% of the continent -- 90% of the earth's store of ice -- which holds 70% of the earth's fresh water, is threatened by global warming.
