Does glabal warming exist?

Question

DOES GLOBAL WARMING EXIST? Sorry! :)

Answer 1

No. If you look at a graph over about 20 years in one tenth of degrees increments it is very random.

Answer 2

Sure does exist. The planet has been warming up and cooling down for millions of years, it's a natural cycle of the earth. Some speculate that we are making it happen a little faster than it should but it is just a theory. When the earth had thousands of active volcanoes, they spewed more pollution into the air in a day than man kind could do in 300 years. Most people are ignorant to the fact that once the ice caps have melted off and all of that fresh water is dumped in to the ocean from the ice, the oceans and seas will stop circulating around the globe. This is what keeps our planet relatively warm. When this does happen then we will plunge back in to an ice age with glaciers that will come down as far as Chicago. Once the the oceans freeze again then the salt content in the water will return to the right amount for the seas and oceans to circulate again moving the warm water near the equator around the Earth again slowly warming up the planet causing the glaciers to recede once more. So as you can see this is a cycle that continues on earth over and over again. If you watch the history channel, this explains why so many ancient cities are under water, when there is more ice on the Earth the water levels are lower, those cities were built during an ice age.

Answer 3

Yes. Global surface temperatures have increased about 0.6°C (plus or minus 0.2°C) since the late-19th century, and about 0.4°F (0.2 to 0.3°C) over the past 25 years (the period with the most credible data). The warming has not been globally uniform. Some areas (including parts of the southeastern U.S.) have, in fact, cooled over the last century. The recent warmth has been greatest over North America and Eurasia between 40 and 70°N. Warming, assisted by the record El Niño of 1997-1998, has continued right up to the present, with 2001 being the second warmest year on record after 1998.

For the Northern Hemisphere summer temperature, recent decades appear to be the warmest since at least about 1000AD, and the warming since the late 19th century is unprecedented over the last 1000 years. Older data are insufficient to provide reliable hemispheric temperature estimates. Ice core data suggest that the 20th century has been warm in many parts of the globe, but also that the significance of the warming varies geographically, when viewed in the context of climate variations of the last millennium.

According to the range of possible forcing scenarios, and taking into account uncertainty in climate model performance, the IPCC projects a global temperature increase of anywhere from 1.4 - 5.8°C from 1990-2100. However, this global average will integrate widely varying regional responses, such as the likelihood that land areas will warm much faster than ocean temperatures, particularly those land areas in northern high latitudes (and mostly in the cold season).

Answer 4

Yes global warming exists.

Answer 5

If the projections some scientists use are correct, we may be in a warming period, but...it's a planetary function, and those who are trapped in the myopic view of the brief period man has been polluting, and our puny affect, are missing the bigger picture -- even during man's existence in the pre-technological age, things were changing before we could possibly have contributed to the affect -- the normal "ebb and flow" of weather patterns. The question is, of course, a leading one...the truer question is, even if we lived a totally agricultural/natural lifestyle on this planet, without our machines and their pollutants, totally "in harmony" with the earth, would this still be happening? If the answer is possibly "yes", then you have to question your assumptions about "blame". Maybe what's happening would happen regardless of whether we were here or not! It's a universe, folks!

Answer 6

The temperature of the earth the sun fluctuate with time. The fact that the global temp of earth is in constant flux is irrefutable. But the theory of global warming caused by man is just that, a theory. A theory based on temp readings taken accurately for only a fraction of this planets life, during times of war and strife, with no oversight by a central agency.

Answer 7

No glabal warming does not exist, nor does global warming

Answer 8

It seems to from the months of April to around October and November. Then global cooling seems to take over, and then the process seems to repeat itself the following April. Now, if you're on the southern side of the globe, well, the cooling begins in April and the warming begins in October or November. Either way, there seems to be a 12 month cycle associated with it all, unless you talk to a democrat. They seem to think it keeps on getting warmer all 12 months. I think they're smoking something funny, or snorting or injecting, etc., etc., etc.. And, like most everyone else doing such stuff, you can't ever seem to get reality across to them. Oh well.

Answer 9

Yes, global warming does exist. Is it caused by humans actions? I don't think that is the complete story. It is not a grand conspiracy it is simply part of evolution.

Answer 10

global warming does exist

Answer 11

yes GLOBAL warming exists
