How is global warming a result of human activities?

Question

I know already, CO2, when humans hurt trees, hair sprays.. not sure on other facts can't find it much on google

Answer 1

to make a long story short it isnt. the cause of global warming is the source of heat for the planet itself-the sun. the sun has its own cycle of hot and warm periods, by which we are indirectly affected

Answer 2

Well when we use cars, trains, factories, etc. it emits greenhouse gases that get trapped in the atmosphere.  This causes the earth to warm up and melt the polar ice caps which will change the current of the ocean (because there will be so much water flowing from the opposite direction) and it may cause another ice age.  When we cut down trees, it makes it harder for the ocean and the remaining trees to suck up all of the CO2 we emit to the earth.  That's is how everything gets stck in the atmosphere.  So, global warming is OUR fault, not the animals or the trees or the ocean, it's ours.  We're the ones that are messing with the enviornment and s******g the earth up.

Answer 3

When burned, fossil fuels emit CO2 into the atmosphere. CO2 is a greenhouse gas. Greenhouse gasses trap heat. Excess Greenhouse gasses trap more heat. Earth's temperature rises. Voila, Global Warming.

Answer 4

Generally global warming is a natural process that provides the earth with the temperature needed for plants and humans..Today however , we mean the problems that are caused by this natural process, because the pollution of environment from the energies of people.

The energies of persons cause the stocking of more gases of greenhouse but also the increasing of the number of CO2 in the atmosphere.. (CFC's).

Answer 5

I don't believe there is anything humans

can do to change climate, weather, or

global warming. Before you know it, some

idiot  will decide we need to get rid of the

sun and moon.

Answer 6

Nobody said it's JUST human activities.  We CONTRIBUTE, but we are not wholly responsible, some of it is natural.
