Why do people believe in man-made global warming?

Question

The ice caps on Mars are receding several miles a year, and the moons of Saturn and Jupiter were ice and are now liquid seas. This is much faster than the warming on Earth, yet there are no SUVs on these planets, so how is that happening? Is it because it's a natural process rather than man's intervention?

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 1

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.

Answer 2

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/antarctica/law/law.html
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.

In addition to the peer-reviewed science cited above, a good overview of the attribution evidence (including much more subtle statistical tests) can be found here:

I invite you to compare the quality of sources cited in this answer with anything cited by GW skeptics. Then draw your own conclusions.

Answer 3

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.

Answer 4

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.

Answer 5

i'm nevertheless slightly sceptical, in spite of the fact that i in my opinion care approximately our wild locations. I do in spite of the incontrovertible fact that think of that we could continuously take the threat heavily. The information proves that organic cycles of climate take place on a grand scale. there have been as quickly as lions, hippos and elephants wandering the united kingdom nation-state, approximately a hundred and twenty,000 years in the past. That became an interglacial heat spell. the subject that may no longer disputed, is that those issues take place certainly, in spite of everything the Scottish nation-state is packed with glacial beneficial properties. in spite of the incontrovertible fact that, the information ability that our further contribution to worldwide warming is making it take place at a quicker fee than existence can handle. we are speaking approximately climate replace occurring in many years, incredibly than spanning centuries or 1000's of years. flora and fauna has coped with climate replace incredibly properly interior the previous. woodlands and grasslands can circulate at their snails p.c.., to maintain song of the circumstances that healthful them. those days there are further subject concerns. we've our flora and fauna trapped in wallet that are surrounded with the help of farmland. The organic "corridors" are long gone. flora and fauna charities are doing their maximum suitable to make our wild locations extra joined up. If climate replace keeps because it incredibly is and there is no area for issues to circulate, then we are able to lose a lot. besides, i think of my important situation is that i do no longer elect it to be genuine.

Answer 6

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

Answer 7

Oh, yes...there are SUVs on Saturn and Jupiter. Al Gore saw them and James Hanson confirmed it. They're there.

Answer 8

Joe Bleu, do you really believe global warming started in 2000 with George Bush being elected?

If so, you are flat crackers bucko!

Answer 9

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.

Answer 10

The governments have brain washed the people to believe about man made global warming.
