Do you believe in man-made Global Warming?

Question

if you do, then a 2 minute video can prove you wrong.

or an hour long video can REALLY prove you wrong.

Answer 1

That "swindle" movie is wrong. It is simply a political statement which distorts science. The director has a history of putting out misleading stuff. In 1997 he made a series for Channel 4 called “Against Nature”, which compared environmentalists with Nazis. Channel 4 had to apologise for the misleading stuff in that one. The present movie is also a distortion of the science. More here:

"A Channel 4 documentary claimed that climate change was a conspiratorial lie. But an analysis of the evidence it used shows the film was riddled with distortions and errors."

"The science might be bunkum, the research discredited. But all that counts for Channel 4 is generating controversy."

Channel 4 itself undercuts the movie in a funny way. If you go to their website on the movie you find links to real global warming information. They also have a way to "Ask the Expert" about global warming. The questions go to a respected mainstream scientist who supports (mostly) human responsibility for global warming.

Answer 2

My standard response to global warming skeptics:
1. Oceans are heating up. Yes, it does take lots of energy to heat the oceans. If they are heating, think about how much energy we've already poured into the global environment. Also, only a few degrees temperature change can make a HUGE difference. The oceans in the arctic are maybe three degrees warmer than they were this point last century, but the arctic ice cap is melting in ways never seen before. For example, there never used to be open water in the canadian archipelego, even in the summer - now, there are miles and miles of open sea.

On sea ice generally:

2. Some people will say that solar activity is increasing as part of an 11-year cycle. Yes, solar activity is increasing, but most scientists believe that the effect on the earth's climate has been negligible.
From a NASA press release: "...the solar increases do not have the ability to cause large global temperature increases...greenhouse gases are indeed playing the dominant role..."

3. Many skeptics will say that what humans put out in terms of CO2 is far less than volcanoes, fires, or other animals. As for volcanoes, fires, and animals - those have always been there. They should not have any net effect on the planet's climate. The only changing factor among those and humans is humans and our increased activity.
4. If global temperatures increase, then the temperature difference between temperature zones will remain the same. So there will always be extreme weather events like you've pointed out above.
5. Both sides have something to gain and something to lose. However, the anti-global warming side has much to gain by continuing to fight change - they have a direct expense that they can expect by having to change the way they do things. Keep in mind that some of the most vocal critics of global warming theory are those who are either industry insiders themselves or who are funded by industry. On the flip side, those who are trying to convice the world of the reality of Global Warming have no direct benefit that they will gain - most do not own, say, environmental cleanup businesses. Their benefit is based entirely off of a belief in doing the right thing.

Yes, it's warming but I'm not sure how much is because of us. The sun's output has gone up .15% in the last 30 years and Mars an Pluto are heating up. I doubt that we caused that ...Read about it.
