Why do people believe in man-made global warming?
Or is David Mayer de Rothschild (environmentalist and writer of '77 Essential Skills to Stop Climate Changes') right when he said it's because "they are closer to the sun"?
Answer:
Global warming is an Orwellian Windmill.
It is designed to suck resources, give the people a goal, and get their minds off real issues. Once the junk science behind Global warming comes up dry, they will create another.
Its a religion and Al Gore is the Cult Leader.
The governments have brain washed the people to believe about man made global warming.
WE interfere with the natural order of things by introducing pollutants in the environment.
because before man existed, there was no global warming
Look at how bad things have gotten since bush has been in office.
Mars has it's own wars, they are called asteroids also how much of the shielding does mars not have that we do.
Our atmosphere and the ozone help protect us, does mars even have any of that, I wouldn't think so but I haven't done a mars study so I wouldn't know.
Should we really kill the world we're leaving to our children.
Pie man, yes there was global warming before us.
I believe in it because we're basically making a mess aren't we?
crazyman.you are correct. the factor 'man-made' in global warming refers to the emissions man has created due to the dramatic rise in technology, growth, etc...less than a century ago, cars were not so prevalent :) to really understand the hype.research the mechanisms that occur ..i.e. NOx emissions from cars eventually react with O2 to form O3 which we all know is important in the atmosphere but dangerous on ground level
Joe Bleu, do you really believe global warming started in 2000 with George Bush being elected?
If so, you are flat crackers bucko!
What ice caps on Mars, and Moons in space are frozen and will stay frozen as the temperature of space is more than 100 degrees below zero. Mars Saturn and Jupiter are further from the sun than earth. People believe what they are told. You have clearly been told a lot of foolish and inaccurate information, go to the library and do some research or you will make a bigger fool of yourself next time.
Because its a proven fact.
Fact (noun): a true statement that remains true regardless of whether you like it or not.
I think you just made up the bits about Saturn and Jupiter's moons. But as for Mars, the warming is regional, and the cause is believed to be dust storms (1).
But here's the thing though, there are hundreds of planetoid bodies in our solar system. If what you're saying is true, =all= of them should be warming at a rate inversely proportional to their distance from the sun.
Showing evidence of warming a handful of planets doesn't mean anything. You need to show evidence of warming on all of them, and the warming can't be regional, or have a known cause (like the warming on Mars). Otherwise it's nothing more than an interesting coincidence.
There are many many planets in the solar system, and just choosing the few that may show signs of warming, while ignoring the rest, is cherry picking.
Oh, yes...there are SUVs on Saturn and Jupiter. Al Gore saw them and James Hanson confirmed it. They're there.
So, what's YOUR theory for why the south polar cap on Mars is receding while the north polar cap isn't? Can't be the Sun, because an increase in the Sun would cause both poles to melt. Also, we've been monitoring the Sun from satellites since 1978, and there hasn't been much change in that time apart from the normal 11-year cycle.
What's that? Nobody told you that the "global" warming on Mars isnt' really global? Shame on Rush! How dare he!
But to answer your question, why do I believe global warming is caused by human beings? It's because I spend more time reading scientific journals than listening to talk radio.
1. CO2 is increasing in the air at an exponential rate, with no sign of slowing down.

2. The amount of CO2 in the air has increased 37% since the industrial revolution.
http://www.ncdc.noaa.gov/paleo/icecore/a...
3. This rise is caused entirely by human beings. Isotopic analysis of the CO2 in the air shows that it increasingly contains "old" carbon combined with "young" oxygen.

4. CO2 is a greenhouse gas which causes the planet to warm. This has been known (and unchallenged) since the 19th century, so I won't post a link.
5. The planet is actually getting warmer.

6. Natural climatic forcings can be ruled out as causes of the current warmth:
(6a). Ice ages and inter-glacial periods are triggered by small changes in Earth's orbit, called "orbital forcing." Since Earth's orbit can be computed for thousands of years into the past and future, we know that orbital forcing peaked 6000 years ago, and should be slowly cooling the planet right now.

(6b). Solar activity peaked in 1957-58, and has been unsteadily declining since that time.

7. If the warmth is due to the greenhouse effect, we should see the stratosphere getting cooler as more heat is trapped at the surface. This is in fact exactly what we have seen. This also refutes non-GHG causes for the current warmth.
