The Age of Warming

Apparently, many people are forgetting that we had glaciers that carved out the Great Lakes. Since there weren't autos, fossil fuel fired power plants, etc. at the time of these glaciers what sources of heat melted these glaciers? Secondly, since outer space is a vacuum and the earth's atmosphere contains water vapor, what stops the earth's water vapor from going into outer space. We are losing water from our planet and this will certainly increase earth's temperature. Eventually, earth will be a hot, barren wasteland whether people were here or not. Without millions of years of data of earth's climate changes, it is going to be extremely difficult to determine how much modern man is changing the earth's temperature.

oh my god this a real tragedy to see. i live in montana and in the last 20 years i've been watching the rocky mtns get less and less snow. we have all been going through serious warming trends. i guess trends is a bad word for it. when the whole world is in trouble.. praying for six feet of snow everyday ms jackson

What caused the ice age to melt? The earths swings wide every so many thousand years. This causes ice ages because earth is farther from the sun. What keeps our water vapor and air from going into space? A little thing called gravity. We arent losing water. Water is constantly recycled. You are made mostly of water. When you die, it will evaporate and become part of other things (bacteria, worms, etc).

Maybe one of the reasons that causes in this problem in oil. Oil is a great impact on the planet natural resources and a source of life, if the humankind will not do anything in order to stop oil business or get some alternative one for fuel, maybe sooner or later will find our souls on space.

Oh, I forgot to include this. When the earth comes back to its closer orbit, the ice of the ice ages recedes.

Ed and Pat you would do well to recognise the veracity of the poster responding to you - variations in the earths path in the solar system can explain ice ages, except the recent lengthy warm period is not explained by that because there are new factors being introduced to the system. What restraint on the response to the assertion that we are losing water! Not only will Ed and Pat's water get recycled, it might even get put to better use!

Or was that an April Fool from Ed and Pat? Certainly fits.

I'm 73 years old and everything I've read about climate is we are still coming out of the last ice age.Glaciers as far south as the middle of America. I can't get very excited about the people that are forcasting weather far in the future when They rairly get the weather right for 3 days in advance. If there's a problem with this planet its because there are just way to many people. No one has an answer for that.

Actually, we have millions of years of data on earth's climate changes. Modern man IS changing the earths temperature. We are to blame, and we must fix it.

I know that global warming isn't just from fossil fuel burning, but the holes we burn in the ozone with rockets is it's twin brother and we will pay for our stupidness. robert
