What is Global warming?

Answer 1

Some gases ("greenhouse gases") let sunlight in, which warms the Earth, and then block that heat from leaving. That's the "greenhouse effect", and it's a natural thing, mostly caused by water vapor.

Man is making excessive amounts of greenhouse gases, mostly by burning fossil fuels. That causes the delicate natural balance to go out of whack and the Earth warms. That's global warming.

It won't be a Hollywood style disaster. Gradually coastal areas will flood and agriculture will be damaged. But it will be very bad. Rich countries will cope, but it will take huge amounts of money. In poor countries many people will die of starvation, but not all of them.

Most scientists say, in 20-50 years. But we need to start right now to fix it, fixing it will take even longer than that.

Answer 2

Global Warming is a trojan horse for Socialism, wake up Americans. Global warming is at the fore front because politicians found how to use a new platform to get re-elected. The world leaders use it because they found ways to make money at it. This is a made up problem just like Global Cooling in the 1970's. Wake up people. I agree we need to be more efficient with our resources, and we should fine and jail companies who are dumping into our rivers maliciously. I want to stop the raiforest destruction, but to say that global warming is a serious man made issue and we need to destroy the American economy and bow down to the rest of the world certainly does not float my boat. Follow the money on this one and you will see that it is all for political gain and grant money for those scientists who profit off of the government if global warming stays at the front of the issues. Look deep into the Keoto (sp?) Treaty, first of all they took jets to a non-central resort location. Not very environmentally concious. THen in the parameters of the treaty they have a clause that makes it so you can buy or sell polution credits. This is all about shifting wealth and breaking down the United States. This is painfully obvious, just look at peoples agenda. The earth's mean temperature has risen .6 degrees C in the past 125 years. Greenland's icecaps have gotten colder in the past 10 years. The Scientists who do not gain anything on their posisition will tell you that the earth has a natural progression and this is what we are seeing. The UN report is made up of POLITICIANS not a good spread of scientists. THere are as many or more scientists who believe that man in NOT the reason and it is over hyped, but their voice is not heard in the LIberal Mainstream Media. This issue is 99% political, and an attempt to make the USA a socialist nation, and eventually communisim. WAKE UP AMERICA, IT IS TIME TO BE AMERICANS. FOR THE PEOPLE BY THE PEOPLE. STOP THE LIES

Answer 3

The progressive gradual rise of the earth's surface temperature thought to be caused by the greenhouse effect and responsible for changes in global climate patterns. An increase in the near surface temperature of the Earth. Global warming has occurred in the distant past as the result of natural influences, but the term is most often used to refer to the warming predicted to occur as a result of increased emissions of greenhouse gases.

Answer 4

A gradual increase in the global average temperature, always followed by a gradual decrease in the global average temperature.. which is in turn always followed by a gradual increase.. ( you get the picture ).

Anybody who points you to Al Gore's mindless babble is not doing you a favor. They want you to ignore science and accept a theory tailored to fit a political agenda.

There is, in fact, no proof as to what the cause of climate shift is... much less who is responsible. What we do know is this:

1) Climate shift was taking place long before humanity industrialized. It's been MUCH warmer on the planet before and it will be much warmer at some point in the future ( it will also get cooler at some point as well ).

2) The increase in CO2 level takes place AFTER the increase in temperature.. making it hard to believe it is the cause.

Answer 5

Global Warming is a gross deception by the environmental movement to promote the goal of increasing income from both donations and litigation while at the same time increasing political influence.

Answer 6

In a nutshell, it is when Carbon Dioxide is released into the atmosphere, and it tears apart the ozone layer, which lets harmful UV rays from the sun in.
Although I might be confusing Global Warming with the greenhouse effect..=\

Answer 7

The emission of gases(such as from a car) into the atmosphere which then traps the heat from escaping above. That is the heat provided by the sun. Hence the planet gets warmer as more and more gases go into the atmosphere.

Answer 8

Cell phones transmit heat and the more people using cell phones is raising the temperature of Earth.
Just a guess.

Answer 9

Watch the documentary An Inconvenient Truth. It explains everything very clearly.

Answer 10

It is a myth.
