Yes. If mankind does not change its actions then soon the world will be flooded by the melting polar ice caps or the air won't be breathable by any life on Earth.
No. There is no problem regarding Global Warming and we can continue living our normal lives for many years without worrying about it.
According to many sources, many species will soon go extinct because of global warming. (http://www.nrdc.org/globalwarming/fcons/fcons3.asp) (http://www.nature.org/ourinitiatives/urgentissues/global-warming-climate-change/threats-impacts/wildlife-at-risk.xml)
It would take an actual effort to cause meaningful change and while fossil fuels would eventually run out they would still be cost effective for a while. While climate change wont cause and apocalypse it would cause huge instabilities with will cost us countless lives, massive economic downturn, and billions of dollars in damage (if not trillions).
If the rate of global warming increases at the same rate that it has, Earth will be uninhabitable by as soon as 2100. Now, of course we will have global warming prevention efforts no matter what so that is not necessarily doomsday. We will however at some point have to face this problem because by the time this becomes an urgent problem, it will be too late. If we are not to stop global warming now, when are we?
It is still a problem but the worse a problem gets, the harder it is to deny it so soon people will have to accept it and we will be able to get more done. on it.
Anthropogenic global warming is.
Alternate technology that doesn't produce as much global warming is becoming cheaper and more efficient.
I agree ... its a non issue. Its been known that this type of thing would work itself out. There wasn't an 'irreversible' point or any of the other crazy hyped up garbage. Liberals took this to a Y2K level yet again. Energy efficiency is trending as it always has. It was asinine to think the world would stick to industrial revolution class pollution without liberal intervention. All of it was unnecessary.
Global warming, is a myth. Climate change is real, but not on the scale scientists lead it up to be.
