Sorry deniers, but since the 1997 international accord to fight global warming, climate change has worsened and accelerated — beyond some of the grimmest of warnings made back then.As the world has talked for a dozen years about what to do next, new ship passages opened through the once frozen summer sea ice of the Arctic. In Greenland and Antarctica, ice sheets have lost trillions of tons of ice.

Green Freaks are Nature Nazis indeed. They will use any totalitarian method to do Adolf Gore's bidding. They will never control me though, I am going to go kill 5 polar bears and throw a bunch of trash in a ditch in honor of this video.

@Nightversionn Nothing delusional about hard science. Delusion is clinging onto speculative conclusion like they're "scientific fact."Plus your information about the polar icecaps is completely false. Fort percent gone? That's madness. It's actually increased as a whole over the past fifty. You're referring to one very specific peninsula in the arctic which is dismiss able when the rest of the ice cap is increasing.

@Nightversionn There's also some of the coldest years within this decade. The trend you discuss also proves a COOLING trend. This is fact. Also the modern record is data from the past one hundred years....even if it was two hundred that's still insufficient data when compared to 4.6 billion the earth has been around.

Global warming deniers are pretty delusional, or pretend to be obviouslyThe entire north polar icecap, which has been there for most of the last 3 million years, is disappearing before our eyes. Forty percent is already gone. The rest is expected to go completely within the next decade. What do they think is causing this?????????

"The last 10 years are the warmest 10-year period of the modern record," said NOAA climate monitoring chief Deke Arndt. "Even if you analyze the trend during that 10 years, the trend is actually positive, which means warming."

It's Man-bear-pig!

EXCELSIOR!!!!!

If anyone believed that man was responsible for global warming (sic...man made globl warming) and the entire solor system has been warming and all of its planets of which earth is the smallest; can we not logically deduce that Martians, and the inhabitants of Venus and Pluto are responsible for their planets warming? Oh! That's right! There are no inhabitants of Mars, Venus and Pluto...Hmm, guess we're responsible for these planets warming, too, huh?

And the effects of greenhouse gases are more powerful and happening sooner than predicted, scientists said."Back in 1997, the impacts (of climate change) were underestimated; the rate of change has been faster," said Virginia Burkett, chief scientist for global change research at the U.S. Geological Survey.AP Nov 22, 2009

Gore: your lips are flapping, which means you're LYING.

I am here to educate you about the single biggest threat to our planet. You see, there is something out there which threatens our very existence and may be the end to the human race as we know it. I'm talking, of course, about Manbearpig. It is a creature which roams the Earth alone. It is half man, half bear, and half pig. Some people say that Manbearpig isn't real. Well , I'm here to tell you now, Manbearpig is very real, and he most certainly exists—I'm cereal.-Al Gore

after wildfires, all new plants grow, and all the dead ones are gone, wildfires r natural in wilderness. and did u know that its snowed 3 times in the past 4 years in houston texas? and before that was in '93. its just randon, it isnt getting hotter or colder

hey Al, let me ask you something... whats more important, people or the environment? how about that question to other Global warming activists?

Here's something American media are virtually guaranteed to not report: a British court has determined that Al Gore's schlockumentary "An Inconvenient Truth" contains at least eleven material falsehoods.

If people stopped and understood what CO2 is they would think hang on that thieving Nazi eugenics scumbag is trying to tax me for breathing. Hang Al gore for the deaths of millions in Africa due to his Nazi beliefs

just like the medieval times. You think that deserts were always deserts and grasslands were always grasslands? What you and so many others have said does not prove man made global warming. That is whats in question and as of right now failing miserably in its proof.

Russian hackers hacked the scientists who put out the Global warming data.The scientist we're caught red handed manipulating that data to suit their own aims.The truth is that we are in a 9 year cooling phase.The sun regulates everything this difference.I'm sorry but you've been had.Tell your friends they are being suckered.And that the green movement is in actuality red.Communist world control via the U.N. and by a carbon tax system.Peace.

The world's oceans have risen by about an inch and a half.Droughts and wildfires have turned more severe worldwide, from the U.S. West to Australia to the Sahel desert of North Africa.Temperatures over the past 12 years are 0.4 of a degree warmer than the dozen years leading up to 1997.(Associated Press) Nov 22, 2009

Nightversionn, can you give me the last year that the sea levels remained consistent? Can you remember a single year of your life that there were not floods and droughts?The damage isn't to the planet, the damage is to interplanetary creatures. Al Gore is a politician. Why would you trust him?
