I over heard someone say that this isent the first time that the polar ice caps have melted and the earth has gone though a global climate shift. Is this true or false.

When a catastrophic event, probably an asteroid hit, shook the earth and slid the geographic poles to their present landlocked positions, from the positions in the heyday of the dinosaurs in warm seas, we started the cycle of 90.000 years of cold and ice, and 10,000 years of "Global Warming" due to natural causes. This has been traced back at least as far as 4 cycles, and the graphs show lots on interesting features, such as temperatures higher than we have projected now happening naturally, and ups and down during the warmed period, also naturally.

It is of interest that the rises in CO2 occurred hundreds of years AFTER the warming, so we do not have evidence of CO2 being the driver of Global Warming from history.

There is some evidence that the warming is associated with sunspot activity, particularly with respect to the Little Ice Age, and I have seen a lot of folk not realizing how much the energy output of the sun in particle radiation as well as electromagnetic waves can affect us.

We are fighting a fact blackout by those who make money off the Global Warming scare, and those who just like to scare and control people.

But it is true that this happens every 100,.000 years, and is natural and gets hotter than it is projected now at times. At the end, the temperature drops and drops fast into glaciation.

History tells us too that the times of Global temperature rises are times of prosperity, lots of good crops, lots of land for everybody, etc. Arts also bloom in times of plenty and make people happier.

So I cannot fathom why certain people and groups want to prevent peace and prosperity!!

But even the most rabid proponent of Global Warming being all man-made and therefore evil and needs to be controlled at all costs will admit that this is a natural cycle, and even the polar bears have survived all the previous warmings in fine shape!

Btw, the 1950-1975 period showed that by emitting dusts into the atmosphere, we can do as big volcanos do, and cool the globe, about as much as we wish.

And the GW folks try hard not to let you see how their efforts are causing millions of deaths and much poverty worldwide, while those in on it like Al Gore get filthy rich. Check it out, Gore throws huge concerts while people die for lack of electricity scant miles away!!

Makes one to think, doesn't it?

This is the first time Earth has heated up because of human activities.

In the past there have been four complete ice age cycles that we know about when temperatures have been considerably warmer or cooler than they are now. A typical cycle lasts about 120 million years and climate change occurs incredibly slowly.

Within these very long cycles are shorter warming and cooling cycles and whislt they don't bring about the start or end of an ice age they do cause the planet to warm or cool considerably.

Four times the polar ice caps have melted, this has been the culmination of 60 million years of natural warming. Because global temps are now rising faster than has ever before been known we could see the Arctic Ice disappear in as little as 40 years. For now the Antractic ice is receding but very slowly, it will be many thousands of years before it melts.

All polar ice has melted before, millions of years ago. Then it froze again, also millions of years ago. This is the ice age and warm age cycle that has repeated several times. We do not know for sure what causes these cycles, but even if the cause of the present cycle is different from all those past ones, the effects will be the same. No big deal.

Anytime the Earth "heats up" it undergoes global warming. And the Earth has heated up and cooled down many times in the past entirely free of human influence. So you heard right. Hopefully whoever said that followed it up with something like, "Of course, this holds no relevance to the question of whether or not humans =can= affect the climate".

Earth has experienced warming and cooling many times in the past. The recent Antarctic EPICA ice core spans 800,000 years, including eight glacial cycles timed by orbital variations with interglacial warm periods comparable to present temperatures

A rapid buildup of greenhouse gases caused warming in the early Jurassic period (about 180 million years ago), with average temperatures rising by 5 °C (9 °F). Research by the Open University indicates that the warming caused the rate of rock weathering to increase by 400%. As such weathering locks away carbon in calcite and dolomite, CO2 levels dropped back to normal over roughly the next 150,000 years

Sudden releases of methane from clathrate compounds (the clathrate gun hypothesis) have been hypothesized as a cause for other warming events in the distant past, including the Permian-Triassic extinction event (about 251 million years ago) and the Paleocene-Eocene Thermal Maximum (about 55 million years ago).

The television series The Universe on History Channel is awesome if your into astrology and also Neil Degrasse Tyson is a great astrophysist with cool new views on everything

You're no longer bizarre. You simply have not utterly proficient your self at the subjects of local weather difference and international warming. Once you appreciate the technology, you're going to detect that the doomsday predictions and founded on deficient medical ways and sloppy statistical ways. It will then come to be transparent that the loudest proponents of anti-international warming reasons are not anything greater than fearmongers, watching to scare you out of a dollar. Take a appear at Al Gore's propaganda movie for evidence of that, and you'll be able to see that he is just a "local weather educated" considering the fact that he thinks he's, and identical to that, you could have wasted $10 and a couple of hours of your lifestyles. Furthermore, whenever you appreciate the basics of local weather difference, you're going to be capable to make rational choices on what you'll do to upgrade your lifestyles and your environmental influence, with out the hysteria and hype fed to you by means of the media. It's effortless to leap at the international warming propaganda bandwagon, considering the fact that the bandwagon's continuously the best location to be. But whenever you appreciate the basics of local weather difference, you'll be able to detect that the bandwagon is little greater than a boat of fools, crusing within the provervial sea of lack of information.

The earth has gone through global warming a bunch of times. We go through it and the ice caps melt and mess up everything. Rivers flow differently and saltwater and freshwater mix and then it winds up getting cold again.

Something like that. But yea its' happened before, just not recently.

Its not global warming. It has to do with the magnetic poles shifting. It causes changes in tempeture, weather, natural disaster. Its a slow progress. Polution doesn't help our ozone and our defense against solar flares, but whats happening is not due to global warming.
At different points in history, where there are currently deserts there have been lush forest. Things like that, the earth changes.

The earth has been warmer several times in the past. Typically, these maximums have been 3-4 degrees Celsius hotter than current temperatures.

From fossil evidence and the existence of oil deposits in northern Alaska.. we know there used to be tropical forests there. I'm pretty sure it would have to be quite a lot warmer there than it is now to support that..
