when fossil fuels are burned from cars and other gas using vehicles. Since carbon dioxide is a greenhouse gas it causes heat by it sucks infrared radiation that causes heat and makes it so it is hard for the sun rays to escape.
Dude all this global warming is going to make polar bears extinct.

Increase in average temperature of Earth since the mid twentieth century and it's continuation. Temperatures have been rising for a few decades now and if idiots continue to pretend it doesn't exist then they'll cause all of humanity to learn the hard way.

The reason Global Warming is an undesirable thing is primarily because it is melting the polar ice caps and raising sea levels. Contrary to popular belief, HUMANS CANNOT BREATHE UNDER WATER, hence we cannot let temperatures rise enough to melt such an amount of ice that'll end up flooding most of the land that we live on and force us to cram in to even less space than what we live in now. Combine that with exploding population rates (Set to triple from 1950-2050, oh joy.) and you have a recipe for disaster.

Of course, anything that's this logical is obviously denied by people. For example, in the US the majority of the Republican party deny it's existence; not because they actually believe in it not existing, but because its generally a rule of thumb for them to disagree with anything their opposition says.

Another funny example could include Britain, where the government raised car tax to encourage people to cycle, carpool, take the bus, etc. This was done to reduce emissions, primarily because 40% of all car rides were less than two miles long. But, as usual, this was met with huge backlashes because people would rather have future generations live in an obliterated world then pay a bit more money.
Global Warming sucks. Too bad large parts of humanity are too retarded to understand it. It's funny, future generations will look back at us and wonder why we stood by and did nothing.

A very real problem. All you idiots out there who won't open your eyes and look past your own closed minded existence, all I can say is that when we've pumped so much CO2 into the atmosphere that you roof caves in, and the flood waters lift your house off the foundations, maybe you'll believe us. Here are seven reasons to believe it's real-
1) Scientific data. You say we're just experiencing the opposite of the ice age, its a natural cycle, scientists have looked at samples from Global Warming periods from the past, and the present is like that, only about 10 times worse.
2) George W. Bush also told us that Iraq had WoMD. we haven't found those yet, have we?
3) We still have ice samples from the last period of Global Warming. People in the future looking back won't have any from now, because the ice is melting to fast.
4) The oceans are rising at a rate we've never seen before, even in the fossil record.
5) Some scientists admitted to having tampered with data showing evidence that Global Warming exists and is a real problem.
6) Give me a better reason why the seasonal temperature changes have been more extreme than any other the earth has faced.
7) The Antarctic Shetland Islands have green grass growing on them, something we can tell from the fossil records hasn't happened since Antarctica settled in its present location.
George W. Bush- Stupid hippies, global warming doesn't exist!
Person- So why then is the globe warming at a dangerous rate?

Noun. The heating of the Earth's temperature as a result of abundant greenhouse gases from mankind. Although global warming is the consensus of the world's scientists, just like plate tectonics, evolution, or gravity, there are skeptics who tend to think other wise. Even if you don't think it exists, it is still no reason not to live a sustainable (or "green", whatever) lifestyle. That's what we call a win-win situation. However, the people that don't think it exists are basically looking for a reason to justify their fear of getting rid of their material possessions they hold so dearly; be it a car, hamburger (large carbon footprint), air conditioner, etc.
The people against the conservation of our earth are the reasons global warming exists. Don't be another coward unwilling to make a change. Do yourself, others, and the planet a favor by researching sustainable alternatives to lower your carbon emissions and contribute in the preservation of the world. Caring about something other than yourself doesn't make you a hippie, it makes you a human being.

A potentially fatal action by humanit, which has been linked to increased drought in many regions already, particularly in Africa, where it is believed to have worsened political conditions.

Don't believe me?

An enormous number of scientific foundations have released warnings that Global Warming could drastically alter climatic patterns, threatening the orientation of current farmland, cities, and populations. Increased CO2 concentrations in the atmosphere have also been linked to lower nutritional content in various food, off setting the theoretical "bounty harvests" various politicians have theorized to be produced in the future.

Still don't believe me?

Global Warming may have natural causes as well as human related ones, however there is disagreement on the degree and even existance of the natural causes in the scientific community. Human activities, however, are undoubtedly related to it, according to nearly every scientific study.

Unfortunately, there is still widespread misunderstanding of the nature and severity of Global Warming among the populace, blatantly derived from the unduely skeptical and irrationally hesitant media coverage. For instance, only 35% of mainstream media articles accurately reflected the scientific "debate", that there are definately anthropological causes and possibly natural ones, a stark contrast to accepted scientific theory.

You know, if the scientists and climatologists, who are educated in the feild of global warming are saying that the world is getting hotter, then why debate with them. Bush doesn't give a damn about global warming because he sucks up to the oil companies. Its not just a theory its a proven fact. It used to snow where I live now it doesn't snow anymore.
Fucking conservatives don't give a fuck about global warming because if they did do something they would just be millionaires instead of multi-millionaires.
