If we are causing global warming, who is causing global warming on Mars?

Global warming is a plot devised by scientists of the world to dominate the planet !!!\n\nYou see if we accept this theory as fact from then on scientists will be able to control everything that we do based on the complex interactions, almost unfathomably complex, between consumption and global warming effects -- thus, scientists will be allow to make educated guesses if they like, which will almost always certainly result in politically correct and repressive conclusions that forward the goals of this neo-imperialism.\n\n\nThe bottom line for this question is that the LONGEST historical charts showing the temperatures on Earth show that we are currently quite COLD !!!  In fact we are currently tied for the coldest period ever on the long term charts, the entire period if life on Earth. Thus, odds are very good that temperatures will raise no matter what we do so over the very long term scientists will be found to be correct that the Earth is indeed warming up. And I am sure they will continue to blame the heating on human activity and they will continue to try to use this to gain control over the free peoples of the world. Although since this trend that shows the Earth being currently quite cold is a very long term trend, in the million of years, so this is a long term gamble for the scientists a lot can happen between now and when the longer term trend is likely to kick in.\n\nBut the idea that this heating is unnatural or some how damaging to the Earth is silly because the long term charts show that the Earth is usually much warmer, during the last 542 million years, the entire period of time that life has existed on Earth.\n\nEvery classroom and library show have a large poster on the wall to show the temperature record of the Phanerozoic period, the last 542 million years, to remind people of the absurd conclusions science can reach from time to time.\n\nIsn't it interesting that 542 million years shows that we are currently tied for the coldest temps EVER !!!\nhttp://en.wikipedia.org/wiki/Image:Phanerozoic_Climate_Change.png\n\n"The Phanerozoic (occasionally Phaenerozoic) Eon is the period of geologic time during which abundant animal life has existed. It covers roughly 545 million years and goes back to the time when diverse hard-shelled animals first appeared. The Phanerozoic eon is still ongoing." \nhttp://en.wikipedia.org/wiki/Phanerozoic\n\nIf you look at the chart of Holocene temperature variation we are not hotter, on the average we are cooler -- notice the long term cooling trend or downward slope of the chart.\nHolocene Temperature Variations ...\nhttp://en.wikipedia.org/wiki/Image:Holocene_Temperature_Variations.png\n\nFrom this chart it looks like we are currently on the top of an upward swing that started with the mini-ice-age in the 1600s and that we are currently topping out.\n\nThis is probably why scientist are currently predicting in the future, both, much HOTTER weather, and a new ice-age, it is because it is time for a new long term downward trend -- well, that is on the short term chart showing the thousands of years, yes in terms of millions of years we are still currently VERY cold !\n\nAnd 5 million years of temps changes shows we are cooler, but fluctuating ...\nhttp://en.wikipedia.org/wiki/Image:Five_Myr_Climate_Change.png\n\nAnd 65 million years of temps changes shows we are\ncooler, but fluctuating ...\nhttp://en.wikipedia.org/wiki/Image:65_Myr_Climate_Change.png\n\nIsn't it interesting that 542 million years shows that\nwe are currently tied for the coldest EVER !!!\nhttp://en.wikipedia.org/wiki/Image:Phanerozoic_Climate_Change.png\n\nSo I think the scientists that know about this LONG term temperature change believe we will get hotter no matter what, so they can't loose even if the current theories of Global Warming turn out to be BULL of planetary proportions !!!\n\nThe ice-age temps shows our current temps to be fairly typical, notice the other peaks were HIGHER and sh

UV carries more energy than infrared. UV has the highest frequency. \nUV is not the cause for globalwarming. As the atmosphere gets more and more CO2 it will trap more infrared light coming from earth. CO2 is the cause for globl warming. \nThe infrared radiation from earth is the radiation it emitts as the surface absorbs light from all other frequencies, including UV, although not alot of UV reaches the surface. Instead it is absorbed by the ozonelayer. That means it gets hot up there but that heat (or infrared light) doesn´t make it down to the surface. Instead it is radiated off into space.

It depends on a variety of things: the angle of entry into the atmosphere, the size of the comet, the composition of the comet, etc.\n\nAn interesting note: one of the proposals for terraforming Mars is to use ice-coments to raise the amount of water vapor, create a greenhouse effect, and both warm the planet and add to the water on Mars.

Mother Earth is first, Then Mars, our sister planet which was once a great civilization.   If we do not stop global warming and all the pollution, our Earth will be just like Mars within the next 1000 years.

Why do we live in Mars ?

mainly CO2, which is why scientists are researching the planets to find out effects/ways to prevent global warming. it is often called "earths evil twin"

I do not get Popular Science, but I have heard proposals to put a sunshade in space to reduce the solar energy reaching Earth and so solve the global warming problem. This would definitely work, but I think it is too soon to proceed. What if we cool the Earth too much? Who would be to blame? If NASA put up the shade and Finland or some other country had a bad winter, would the US have to pay damages? It would be a political nightmare. With great power comes great responsibility. If we can really control the weather, then if somebody doesn't like the weather is our fault. Do we want to take that responsibility? Yes we do if massive bad stuff has already happened that can be 100% blamed on global warming, but when was the last time the world agreed 100% on anything? Even if sea levels rise 100 feet and we put the shade in place, somebody in the world would sue us anyway, but if we put it up now, before sea levels rise at all, EVERYBODY will sue us!

Global warming is caused by an increase in greenhouse gasses in the atmosphere.  Global warming has been proven, the only people who argue against it have no understanding of science and no idea what is going on in the world.  Humans are not the only cause of greenhouse gasses, but we contribute to the problem greately.  The fact is that the earth cycles through warming and cooling periods but manking disturbs the normal process and increases the rate of warming (mostly by CO2 increases from burning oil.)  There are natural sources of CO2 and other greenhouse gasses as well, volcanoes can spew millions of tons of CO2 in a matter of days... the earth has supported life through very hot and very cold peroids, but there is NO realistic argument that humans don't influence global warming.\n\nThe greenhouse effect is necessary for life as well, if all of the CO2 was elimated from the atmosphere life as we know it on earth would end, the earth would be a frozen, barren wasteland.  Without any greenhouse gasses the earth would not maintain a reasonable temperature; nights would drop to -80 Celcius on the warm parts of the planet... \n\nThe earth will recover from all of the damage we do when we are gone... life adapts, species are eliminated every year, but no little coverage is given to the new species the are discovered every year... evolution is in progress, global warming is a change, not a destruction.

I'd lay pretty good odds that the destruction of a planet in our solar system, and one not even that far from us relatively speaking, would have such catastrophic consequences on the Earth that we'd probably all be destroyed. That is one reason we might resist the otherwise obvious urge to blow up Mars.

Venus.  \n\nIt is the second nearest planet to the sun and due to its atmosphere full of carbon dioxide and sulfuric acid, it has the ability to trap heat.  So, basically, major global warming is taking place on Venus.\n\nAlthough Mercury is nearer to the sun, its atmosphere is weak and contains sodium, potassium and oxygen.  These, when exposed to the sun's rays, are lost/decomposed.  Therefore, there is not much atmosphere left to trap the heat, leaving it cooler than Venus.

Because only 30 years ago, the same scientists were talking about the new ice age that was coming.\n\nAnd, historically, the Earth goes through hot and cold cycles. Greenland was once green. Ohio was once covered in glaciers.\n\nAnd right now, the sun is going through a cycle of increased activity. Mars is getting warmer, too. They don't have SUVs there.\n\nAs for whether there is any significant human activity contribution to the current increase in temperature, there is no data that suggests this.\n\nBut are you willing to cause civilization to collapse because of an unsubstantiated enviro-wanker scare tactic? The staggering cost of putting something like Kyoto into effect would cause a severe world depression worse than the Great Depression.\n\nDon't beleive the hype - someone is feeding you a load of bull.

Exactly none. There is a finite amount of energy stored on the planet in the form of fossil fuels. Burning it releases this energy. You cannot add more. There has been heat RELEASED by the burning of fossil fuels onthe planet, which many people believe causes global warming. The only heat energy added to the planet is solar energy.

First to answer you second question: No we’re not terraforming Mars at present. Now for the first question: At this present point our technological development is woefully adequate to handle the issues of keeping this planet’s atmosphere from going into a greenhouse condition. Furthermore, it has taken by some estimate approximately 75 to 100 years for us to bring about this greenhouse climate change, which in a crude sense is a form of terraforming.\n\nThe idea that we could terraform Mars at this present time would be extremely impractical, it would cost hundreds of trillions of dollars, and it would take a very long time to see any results (on the order of hundreds of years). Plus you’d have to figure in the technology needed for such an undertaking, which although is probably available (with our technical capabilities), we’d then have to figure out how we’ll get it there. This would be no small undertaking. You have to remember that Mars has an atmospheric pressure that is less than 1/10 that of Earth and it has a very scant amount of water free-flowing on its surface. The vast majority of the water is locked up in the polar icecaps. Therefore we’d have to increase the amount of Oxygen as well as the atmospheric pressure and free up most if not all of the water on the planet. Plus we’d have to somehow produce an Ozone layer in the Martian atmosphere. Not to mention that Mars doesn’t have an electromagnetic field anywhere near the strength of ours. So basically there would have to be a whole lot of work done to actually terraform Mars.\n\nThe likelihood that some one country could undertake the process of terraforming an entire planet at this time would be highly unlikely.

They are going to try and explore the possibilities of living on Mars in the future due to the fact that they believe the Earth will eventually become unlivable due to the warming of the planet. It probably won't happen in our lifetime but Man will pollute the Earth, the air, and the water so much that we will not be able to survive. The hole in the ozone layer is becoming a major problem.

The ozone layer protects the earth from ultraviolet radiation from the sun.  Some does (and is supposed to) get through in order to keep us from freezing.  But too much UV radiation heats the earth more than necessary (and causes sunburns.  Global warming is caused by greenhouse gases (Carbon dioxide being the most prevalent) which trap the heat inside the atmosphere, causing the earth to get warmer and warmer.

theoretically - you may cause pollution by using a car (car fumes), destroy the ozone layer and thus cause the global warming (by using old refridgerators or sprays with freon in them).
