The natural carbon cycle and the water cycle have produced a greenhouse effect that has kept the planet comfortably warm since life began.

Since the start of the Industrial Revolution about 200 years ago man has been burning fossil fuels for industry, transport and the generation of electricity. This burning has released carbon dioxide that had been stored deep underground for millions of years. This extra carbon has disrupted the natural carbon cycle and seriously added to the greenhouse gases in the atmosphere. It is this enhanced, or accelerated greenhouse effect that is causing what we now refer to as global warming, or climate change.

A: The earth has always been warm. This is the result of the greenhouse effect, supported by the natural carbon cycle of the earth, which moves carbon dioxide in and out of the atmosphere. This has kept the earth comfortably warm for as long as life has existed.

Today when we talk about global warming we are referring to the recent warming which has slowly been happening since man began burning fossil fuels and cutting down forests, about 200 years ago. Burning fossil fuels releases extra carbon dioxide making an accelerated greenhouse effect, and deforestation removes trees that have acted as carbon sinks, storing carbon for hundreds of years. A: The category defines global warming, or global climate change, as a scientific proposal that the Earth's average atmospheric temperature is currently warming up due to increasing levels of greenhouse gases and/or other factors. This distinguishes it from the natural warming effect of greenhouse gases at their long-term normal level.

Climate scientists say that carbon dioxide and methane levels have been rising since the beginning of the Industrial age, in the middle of the eighteenth century. The present rise in average global temperatures would date from the same time, but instrumental measurements did not commence until 1850, so scientists can only use proxies to estimate temperature changes before that time. Scientists at first doubted that global warming was really occurring or, if it was, that it was occurring at a sufficient rate to be a concern for centuries to come. It was not until the late 1970s that they realised that global warming was real and that it presented a danger in the very short term.

No, but global warming can be a probable cause of wildfires.

It has started already. The earth is gradually warming.

Use less fossil fuels

No, global warming probably started in Britain with the invention of the steam engine and the start of the Industrial Revolution. The discovery that coal was readily available underground and that it burned so easily was the trigger for global warming.

His movie about global warming called "An Inconvenient Truth" was released in 2006

The warming caused by Global Warming.

Al Gore didn't start global warming. Global warming started when man began to burn fossil fuels that release carbon dioxide into the atmosphere, at the beginning of the Industrial Revolution, about 1750. Al Gore has been influential in educating people about the dangers of global warming.

Global warming is not important.Global warming isn't happening.Global warming is happening but it's not our fault.Global warming is happening but we can't do anything about it.Scientists are not sure about global warming.

Global warming is a GLOBAL thing, no one is "protected" unless everyone on the globe consciously decides to start treating the planet better.

some possible effects of global warming is sea levels could rise.Also the weather will start to change.

It is a valid theory that humans started global warming through the expansion of concrete surfaces, cutting down of forests, eradication of wetlands, the use of fossil fuels, and automobiles which pump out global warming gases have all contributed to global warming and climate change.

Global warming in itself isn't pollution - global warming is the gradual warming of the earth. However, global warming was caused by carbon dioxide pollution in the atmosphere, but global warming in itself isn't a pollution. yes it is a pollution

The troposphere is warming because of global warming.

Travel to another planet, or stop global warming happening. There is no way to protect billions of people from global warming. The very rich will be able to shelter for a while, but when they have to start producing their own food, they will not survive.

it will pollute the Earth and start Global Warming

Global warming skeptics (or sceptics)Global warming deniers.

Global warming is warming the air. It is also warming the land and the oceans.

ever since people start use vast ammount of electricity global warming has gone up. This is when the polar bears started to be affected. If global warming goes up it means the ice caps start melting, and that means the polar bears have nowhere to go. Hope this has helped

Rubbish did not start global warming. Global warming began when we discovered and began burning fossil fuels (coal, oil and natural gas), which releases the greenhouse gas, carbon dioxide (CO2). Fortunately, the burning of rubbish doesn't really occur and hasn't for decades.

True global warming does not decrease temperatures. So, either the model for global warming's effects is hokus-pokus, or global warming as presently claimed, does not exist. Some global warming followers will have you believe that global warming makes the weather "act crazy". If true, then it is not really global warming, is it.

Yes, global warming is occurring.

Because global warming is hot!

you cant hate global warming?!
