Why do so many people belive "global warming" is caused by us? And if so explain how the ice age melted away ?

Answer 1

Doesn't it just drive you crazy?!? The liberals love the blame game. The earth has gone through so many warming and cooling trends and this is just another one.

Answer 2

Take a look at any of the reconstructed long term temperature records of Earth. It is painfully obvious that the current warming, from 1850 to the present far outstrips the rate of any previous warming trend. Furthermore, the timing of this warming is completely wrong if you think it is just part of the natural Ice Age- Interglacial cycle that has existed for the last 2 million years (approx.). Right now, we should be nearly at the end of an interglacial, and should go into an Ice Age within 1,000 years. Global warming has more or less cancelled that cycle for now.

Luna, and other stubborn skeptics, open your eyes to the facts, which the vast majority of scientists now agree upon. Global warming is a fact, and we are absolutely in 'a period of consequences'. We can either ameliorate the consequences by making some very economical adjustments to our energy sources, or leave our children to suffer much greater consequences than we have had to bear.

The long term temperature reconstructions are shown at http://en.wikipedia.org/wiki/Temperature_record#The_long_term_ice_core_record:_the_last_800.2C000_years

Answer 3

I believe the actual argument is that global warming is being accelerated by our pollutant generating technologies. Earth does go through glacial cycles and we seem to have been coming out of one for a while now.

Our alteration of that cycle may lead to more extreme environmental conditions and possibly alter the way the Earth compensates for the changes. There is also the possibility that our actions may cause temperatures to rise much higher than might be normal during an interglacial period.

That being said; the primary concern is not necessarily that the Earth is getting warmer. It should be what man should be doing to mitigate the process and prepare for the eventual results, no matter what the cause.

Answer 4

Global warming occurs naturally, too, but there's a difference in what is happening now.

Man is causing global warming to increase substantially in a short period of time.

And our civilization is vulnerable to that change. We've spent billions (trillions?) of dollars on buildings near the coasts. And we have an excellent system of growing food that is very dependent on the climate not changing too much.

When the ice age ended, some plants and animals thrived, while others went extinct. We're very vulnerable. We won't go extinct, but the changes will cost so much money that we'll actually slip back toward poverty.

Answer 5

this is probably that yet another ice age will come finally. There have already been 2 on earth that all of us comprehend of, and probably more advantageous. I doubt international warming has what it takes to foster an ice age. that occurs for different causes. although, there are those who believe that we are due for one so who's established with? If it occurs, it gained't were led to with techniques from international warming. the quantity of unpolluted water obtainable interior the northern hemisphere isn't close to adequate to close down any ocean currents. save in ideas, even as ice melts this is a million/8 this is volume in water. The oceans are too large, deep and massive to be affected.

Answer 6

People say we are causing global warming because nobody disputes that we are causing the carbon dioxide concentration in the air to go up all over the world. Even George Bush does not dispute that. And since carbon dioxide is a known green house gas, it is expected to cause additional warming above and beyond the natural warming cycles. The only argument is, how much additional warming will it cause and is that enough to worry about. George Bush says it is not enough to worry about.

Answer 7

So many people believe in global warming because there is an excellent corroboration between graphs of fossil fuel combustion, CO2 percentage in the air, and worldwide average temperatures, for the past 100 odd years. What's more, the rise is accelerating. For a while it had been assumed that the recent warming period was part of the natural cycles of ice ages interpersed with warm periods, but careful paleoclimatic studies have shown that the recent rise in CO2 and temperatures is far greater than anything in the past million years. In fact, we're rapidly approaching CO2 percentages and worldwide temperatures that have not been seen since the Carboniferous Era, approximately 300 million years ago. I say this is cause for concern.

Answer 8

Because they have brains. If you want to have an informed opinion on this topic, don't listen to any politicians- scan the research journals. There is no debate among scientists that humans are increasing global temperature above and beyond the "natural" warming.

Answer 9

its not that man caused it or is causing it....its the fact man is speeding it up...thats all.

so instead of say 100 years to melt a cube of ice that is 1 mile by 1 mile, it now takes 50 yrs to melt the same due to CO2 released by man and him disturbing the earth.
