What is Global Warming and what are the causes of it except of Greenhouse gas and CO2?

Question

To be clear , we know that Global warming is come from greenhouse gas and CO2 but what are the other causes that bring Global Warming and what is its definition of it.

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.

Right now, there are no other significant causes.  The Sun is slowly decreasing, and, if it were up to the Sun, we'd be cooling.

It won't be a Hollywood movie 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.

Proof that most scientists think it's real and mostly caused by us here:

Answer 2

The sun. Bob your wrong. Global warming is the increase in average temperature of earth's atmosphere, water, everything. Anthropogenic Global warming is The increase in average temperature of the earth, due to human activity.

Answer 3

Simple. HUMANS ARE CAUSING GLOBAL WARMING. We litter, don't recycle, waste water, cut down trees, use harmful gases when we drive, etc. WE can only make the difference. If ONE person threw out ONE piece of trash on the ground, thats over a trillion pieces of trash thrown out. If nobody littered, we wouldnt have this global warming issue.
