why is the earth hotter than its been in 4oo years?

Question

scientist say the earth is hotter

Answer 1

Some say our pollution from cars, smoke, etc, is wearing away the ozone. Others think our population is growing way too fast. And some people think we're nearing the end because of what the Bible says in Revelations. I don't know for sure but these are some things I've been hearing!

Answer 2

13 answers up to this point and most say global warming except the first guy with the "falling into the sun" that's a good one. He should get the 10 points for creativity.

Global Schmobal....Greenhouse gas my Toukas ...the Earth is getting warmer because ............ We are coming to the end of an Ice Age. ...They happen in cycles. What? You thought there was only one. Seriously!!

We could stop every car in the world, dead in its tracks and ...... glaciers--still receding..... We could throw the switch on every hydro-floro-carburetor ....and ....still receding. No more fossil fuel pumping .... receding....... Stop cutting down the Rain Forest ... OK maybe if we stop cutting down the Rain Forest we might stop the glaciers from receding so fast but it's really going to happen anyway.

Answer 3

Thinning of the protective layer around the globe resulting more heat from the sun to reach earth, hence global warming

Answer 4

Burning carbon based fossil fuels causes a greenhouse effect which in turn heats up the planet. Cutting down areas like the rain forest, which scrubs CO2 into oxygen, increases the amount of greenhouse gasses, also.

In short, global warming.

Answer 5

Lets see. 5 billion people farting and sweating 15 billion cows farting and belching, lots of cars and trucks , factories, power plants, slash and burn in forests, wild fires and of course volcanoes. And I think the earth is getting as close to the sun as it gets before it heads towards its outward rotation. I think some of it is normal and if we become vegetarians, start walking more, use birth control, plant instead of burn it would probably have no effect on what is a cyclical period of the earth.

Answer 6

because of the global warming we are experiencing... know what causes it? the thick carbon layer which packs in the earth's atmosphere... the carbon layer absorbs heat from the sun but it block the sun rays on reflecting back to atmosphere... so thick of it... were like in an oven toaster... we receive plenty of heat yet we have the least chance of letting that heat out... the green-house effect in short... carbon layer packing is formed also due to the constant burning of plastics way back if not now... but i guess til now still others still butn their plastics... that's why we are in global warming right...besies,the ozone layer has a big hole now due to CFC's from burnt plastics... so heat of the sun can pass trough more easily...yet cannot reflect back due to the carbon layer... one thing also is the emmition from cars and factories... this also contribute to the packing of carbon in the atmosphere...

Answer 7

You might have heard of it: Global Warming. Fossil Fuel emissions breaking holes in the ozone layer.

Answer 8

Body heat from more people than have ever lived on the earth before.

Answer 9

all the crap that we put in the air and when it start melting the north pole ice that's going to kill the gulf stream and when that happens be ready for the next ice age ...so with heat comes the cold brrrr

Answer 10

news flash global warming
ppl got technology and started wasting gas
hummer got invented and tons more gas got wasted
