hmmm... I lifted 10 more pounds today than I did yesterday... that MUST mean that I will be able to lift 10 more pounds every day for the rest of my life..... so I will be breaking the world record for bench press within the year....
That statement is as ABSURD as yours....

What an interesting array of opinions. There is global warming, but is it a natural cycle? Yes - and no. There is no doubt the earth goes through these cycles, but these cycles have always been within certain parameters and have generally increased as much as they've decreased. The last 100 year cycle however, will blow away any previous increases in pollution and cause changes we can't really figure out. What I don't understand is this, global warming or not, it is a bad idea to put all the pollution and crap we are pumping out into the atmosphere. It's bad for us, it's bad for the planet. Let's stop (or at least decrease) our pollution, I think that would be a good answer regardless of the question on global warming.

Did global warming stop in 1998?
The official thermometers at the U.S. National Climate Data Center show a slight global cooling trend over the last seven years, from 1998 to 2005.
Actually, global warming is likely to continue—but the interruption of the recent strong warming trend sharply undercuts the argument that our global warming is an urgent, man-made emergency. The seven-year decline makes our warming look much more like the moderate, erratic warming to be expected when the planet naturally shifts from a Little Ice Age (1300–1850 AD) to a centuries-long warm phase like the Medieval Warming (950–1300 AD) or the Roman Warming (200 BC– 600 AD).
The stutter in the temperature rise should rein in some of the more apoplectic cries of panic over man-made greenhouse emissions. The strong 28-year upward trend of 1970–1998 has apparently ended.
Fred Singer, a well-known skeptic on man-made warming, points out that the latest cooling trend is dictated primarily by a very warm El Nino year in 1998. “When you start your graph with 1998,” he says, “you will necessarily get a cooling trend.”
Bob Carter, a paleoclimatologist from Australia, notes that the earth also had strong global warming between 1918 and 1940. Then there was a long cooling period from 1940 to 1965. He points out that the current warming started 50 years before cars and industries began spewing consequential amounts of CO2. Then the planet cooled for 35 years just after the CO2 levels really began to surge. In fact, says Carter, there doesn’t seem to be much correlation between temperatures and man-made CO2.
For context, Carter offers a quick review of earth’s last 6 million years. The planet began that period with 3 million years in which the climate was several degrees warmer than today. Then came 3 million years in which the planet was basically cooling, accompanied by an increase in the magnitude and regularity of the earth’s 1500-year Dansgaard-Oeschger climate cycles.
Speaking of the 1500-year climate cycles, grab an Internet peek at the earth’s official temperatures since 1850. They describe a long, gentle S-curve, with the below-mean temperatures of the Little Ice Age gradually giving way to the above-the-mean temperatures we should expect during a Modern Warming.
Carter points out that since the early 1990s, the First World’s media have featured “an increasing stream of alarmist letters and articles on hypothetical, human-caused climate change. Each such alarmist article is larded with words such as ‘if’, ‘might,’ ‘could,’ ‘probably,’ ‘perhaps,’ ‘expected,’ ‘projected’ or ‘modeled’—and many . . . are akin to nonsense.”
Carter also warns that global cooling—not likely for some centuries yet—is likely to be far harsher for humans than the Modern Warming. He says, “our modern societies have developed during the last 10,000 years of benignly warm, interglacial climate. But for more than 90 percent of the last 2 million years, the climate has been colder, and generally much colder, than today. The reality of the climate record is that a sudden natural cooling is more to be feared, and will do infinitely more social and economic damage, than the late 20th century phase of gentle warming.”
Since the earth is always warming or cooling, let’s applaud the Modern Warming, and hope that the next ice age is a long time coming.

Last month was freakishly warm here in Finland too. Today it was 5 degrees Celsius, a bit colder than over there in Canada, but still, freakishly warm. I wanted to ask the same question, in light of the weather here, but if you are experiencing the same thing...
It is NEVER this warm- there hasn't been a decent spell of winter yet, and winter is almost over here- IN FINLAND!
There are many economic problems with this- moving logs is impossible because the ground is too soft, roads are destroyed, soil is oversaturated by rain, people cannot sell winter-clothing, and crops are in danger of starting to grow too soon, when they could be destroyed by frost or the onset of the actual winter.
And if the Arctic Ice disappears that will mean no more Gulf-Stream...

Unfortunately, those who claim these are only part of the natural cycles of earth are wrong. If one looks at the actual records and facts about those cycles of warming, they are not similar at all to the warming we are experiencing now. And while Earth might heal itself after a thousand years or so is not really a comfort to me.

There may be some global warming, but there are also weather cycles. If you can go back and look over a number of years, I would guess that you would find a trend. Not time to panic. The grass is green here also, and the weather is unusually warm for January, I am just enjoying every day of it and not complaining. Suggest you do the same:)

First, I believe in Global Warming.
Global Warming is in fact not a good term for it, Global Climate Change would be better. The ozone layer getting deteriorated causes the Polor Ice Caps to start to melt. This cause all of the weather pattern in the world to change. Instead of getting hotter, some places may in fact become colder!

The original theory of Global Warming is based on the ozone hole, and how man has added pollutants that have caused it to deplete. It is still just a theory as they don't know enough about how the ozone layer actually works, and several facts like the pollutants have a higher molecular weight than the molecules at that altitude, volcanism, and if trees and plants contribute to pollution since the byproduct of photosynthesis is a pollutant called ozone as well.. I do agree that the earth behaves in cycles from glaciation to glaciation, and we are just beginning to come to an end to a small epoch there. Nothing to be concerned about, the earth is just doing what it always has done. I think that we should be responsible, but we sure shouldnt be fanatical about making changes. When Mt Pinnatubo blew, it put more CFC's in the atmosphere than about 50 years of manmade pollution.. There really isn't much that we can do to Mother Earth, she is always going to stabalize herself in the end.

Global warming or climate change or whatever PC term people are using today is absolutely real and it will affect our generations of children to come for the foreseeable future.
For all the people that want to live their lives as ostriches, please consider the following facts:
In 1998 coral reefs around the world experienced the most extensive and severe bleaching in recorded history (due to rapid increases in climate change/warming)
Global mean sea-surface temperatures are projected to increase by about 1-2°C in the next century
The life cycles of most plants and animals are critically tied to seasonal changes in temperature, precipitation, and light. The timing of bird migration and breeding is sensitive to changes in temperature, and global warming would be expected to lead to an earlier onset of those activities in the spring. Statistically significant trends toward earlier bird egg-laying and nesting have been reported for sites in Europe (Crick and Sparks, 1999; Crick et al., 1997) and the southern United States (Brown et al, 1999). The earlier nesting in Europe is attributed in part to earlier plant growth, which in turn causes earlier availability of the insects the birds feed upon (Crick et al., 1997). A trend toward earlier spring migration has also been observed for birds arriving in Michigan (Root, 1993).
A shorter duration of ice cover due to an earlier spring has the potential to affect the productivity, life history, and reproduction of aquatic organisms. Earlier break-up (and later freeze-up) of sea ice in the Arctic shortens the time available for feeding and rearing of certain marine mammals and may change the health or size of a population. A new study of polar bears in Hudson Bay indicates that because of earlier melting, the bears now have less time to hunt on the sea ice and must return to shore before they have adequately replenished their fat by feeding on seal pups
These are just a few - there are hundreds of other ecological effects on the food chain from the microbiotic level on up.
It affects us and unless we make this our number 1 issue going forward, we won't have to worry about anything else...

last time the earth went through global warming, temperatures suddenly dropped dramatically and the ice age came to be. i'm not quite sure because i wasn't alive then, but i don't think that instance of global warming was caused by polution.
enjoy it while you can because it just may be the earth's natural cycle of climate change, in which case your town will probably be covered by glaciers in another twenty years or so...

I've never doubted that global warming exists. We are coming out of an ice age, and the temp is rising. But, I believe there is no hard evidence to prove that humans are to blame for it. I believe it is a natural cycle of the planet.

Is the earth getting warmer.. Of course. This is a natural progression of our planet. There is nothing we can do to stop this. Unless you can turn off the sun.The same thing is happening with the polar caps on Mars.. Be glad we are in a warming period those cold ones create huge problems, just ask a dinosaur...
