what is the cause of global warming?

Answer 1

1.Carbon dioxide gas
===it can trap heat and prevent it from escaping to the atmosphere.
2.Roads
===almost all of them made up of bitumen which is very capable in heat absorbing.
3.High buildings
===trap heat from sunlight

Answer 2

The only thing we know for sure is higher temperatures have caused the earth to be warmer.

Scientists seem to have come to a consensus that emissions from the usage of fossil fuels are the main contributor. Since there is little we can do about this at this point, other than pretend that windmillls and dams can replace oil in the short term, we should pray that they and their models are wrong.

Answer 3

Carbon dioxide amounts to only a paltry 3% of all greenhouse gases. Much more important are the amount and distribution of water vapor and clouds in our atmosphere. Water vapor constitutes Earth's most significant greenhouse gas, accounting for about 95% of Earth's greenhouse effect.That's where Al Gore is wrong and why he refuses to debate any scientists in public.

Answer 4

Supposedly all the heat and pollution (or as Al Gore would put it "...not the pollution, but the impurities in our air and water...") that we pesky humans put into the atmosphere. Strangely enough, Al Gore fails to point out that natural sources (such as volcanoes) put out massive amounts of the said "impurities" into the system frequently. Maybe he doesn't touch on this fact because he wants to keep his Nobel Prize. What a stupid, ignorant world we live in.

Answer 5

Too many greenhouse gasses like carbon dioxide and methane being released into the atmosphere through polution like burning fossil fuels, and keeping animals in feed lots. Not enough trees to absorb them and produce more oxygen. They destroy the ozone layer of the atmosphere which protects us from the suns harshest rays.

Answer 6

The sun's rays.
The polluted air holds more of the heat.
Less white ice causes less heat to be reflected back into space.
