for how long has the earths climate been changing?

Answer 1

It is always changing. It is always either going up or down. We have nothing to do with it. It is a natrual cycle.

Answer 2

we humans have enjoyed an extended warm period allowing the human race to continue to be successful. The cycles between warm and cold tend to be in ten thousand year cycles and in all actually we have gone over that time frame. they tell you the Arctic cap is melting, thats true, they dont tell you the Antarctic Cap is increasing in size. The earths orbit changes from almost perfect circular motion to a more eliptical motion(oval) the earths tilts changes in cycles, the suns output changes in cycles, and the other planets gravatational pull affects the suns output as well. there is a current swell of political power with huge companies driving the media and paying for the science to produce the Global Warming science. People get caught up in this frenzy especiall young teens and adults being brainwashed by colleges into their political dogma.Tell me how you would explain the first people(vikings) who explored Greenland, and there was hardly any ice there but rather green plants, and that was not that long ago.

Answer 3

Always. The earth is constantly going through ice ages and global warming. The earths orbit causes it to go through a warming period, its causing the ice to melt which is causing pockets of methane to release into the atmosphere which is causing it to be even warmer. There is nothing that can be done. The earth has done this several times in the past.

Answer 4

since there was the atmosphere. like billions of years ago i think. the climate has been changing for a long time. get cooler and warmer.

Answer 5

Climate change is ongoing, a natural cyclical event that takes place over tens of thousands of years. The current concern over 'global warming' is caused as a result of man's "Industrial Revolution" of these past 150 years. Smoke-belching factories, vehicle emissions, oil drilling, overfishing of the oceans, coal mining, natural gas exploration, destruction of rain forests, depletion of the ozone layer, devastation of mangrove forests and wetlands, eradication of millions of species of plants and animals, air and water pollution, human garbage, and the elimination of nature's forests, wildlife, and pristine areas have contributed to the acceleration of global warming. That means man, plants and animals don't have time to adapt to the coming climate changes, which will result in the extinction of polar bears, remote Eskimo tribes, sea otters, glaciers, and millions of Earth's species which are co-dependent on one another for our mutual survival. We have not been responsible stewards of this planet over which we were given dominion. Now our descendants will live with the consequences of our squanderous squalor.
