Can someone please explain to me what exactly is Global Warming?

Question

All i really know is that its one of the major causes in Air Pollution, so I'm kinda clue less on the whole thing.

Answer 1

Alot of people who answered here referred to a cycling climate. That is climate change, which does exist. Global warming however, is the theory that man-made greenhouse gases are causing an irreversible, catastrophic warming trend in the Earth's climate.

The theory assumes that greenhouse gases affect climate, which has yet to be proven. It has nothing to do with ozone.

Answer 2

Air polution depletes the ozone layer of our atmosphere.
Which in turn lets more sunlight in and melts polar ice caps
which raises the ocean levels around the world. The extra heat coming in raises the temp of the water and bacteria that causes disease grows more easily in the warmer waters. The rise in temp also causes changes in weather patterns.
More warm air to collide with cold air to create bigger storms
such as Katrina and destabilizes ecosystems, which means that animals (including us) suddenly find the climate changing
very drastically and many will not be able to adapt to deal with it and thus will die out. In addition to all this, the coastal areas will be shrinking because the water from melted icecaps causes ocean levels to rise thus covering more of the land in the world.

Somethin' isnt it?

Answer 3

We are on the verge of controlling earths temp. While we have big problems. Here is what we know: Blacktop (roads and parking lots) and buildings heat cities; Air pollution causes lung (And other) diseases, deforestation (causing more destruction -duststorms, hurricanes/cyclones all increasing deforestation) and destroys the ozone layer while heating earth surface; fires cause mud slides, deforestation and pollution-more heating surface temperatures; CFC's destroy the ozone layer raising skin cancer rates and killing off endanger species and increased surface temperatures; lighting produces ozone near the surface and raises air pollution levels-more heating, the suns increased magnetic field are causing increases in earthquakes (more destruction), volcanoes (wow), sun spots and more heating. Cars, airplanes, ships and most electricity production causes pollution, warmer temperatures and destruction...But most of this is in our control outside of the sun (Volcanoes and earthquakes are part of the sun magnetic strength): We need to fix it! That is why I founded CoolingEarth.org an geoengineering web sight.The Mayor's are on the right track, we can have control and economic growth. The fed gov is way out of step. We also need a pollution surcharge to balance the field and advance new technologies

Answer 4

It is part of a natural cycle that has been going on for millions of years. There have been ice ages and thaws documented in the rock layers of mountains and canyons. Now it is a political trick to gouge the taxpayers out of more money!

The "evidence" that we are given is higher temperatures in the cities. A lot of that can be contributed to today's use of digital thermometers vs. the old mercury thermometers. Also, our cities are becoming hotter each year due to covering up the earth with concrete and asphalt. And where are the temperatures recorded? Of course in the big cities and airports of the world.

Answer 5

due to a certain type of pollutants(air pollution), the Ozone layer is getting damaged and hence thinner..which is causing more heating of the earth than sustainable.
this is global warming.

Answer 6

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.

Lots of numerical scientific data proving it real here:

Answer 7

It's a scam to get more government into people's lives and to increase taxes.

The climate is always changing. There is no such thing as a static climate.
