it's NOT 5 to 10 years. The exact measurements start at 100 years (even that is 10-20 times longer than what you said) but the average global temperature, greenhouse gases, etc. have been measured for the last couple thousands of years by analyzing ice from many glaciers around the world and forzen lakes, trees, etc. and they have determined that at around the industrial revolution (what a coincidence... it's all doing perfectly fine until the industrial revolution) the greenhouse gases concentration in the atmosphere skyrocketed (that's relative of course...) and so did the temperature.[b said:Quote[/b] ]i love how "scientists" latch on to 5-10 year weather patterns and read something into it other than the natural ebb and flow of the planet
[b said:Quote[/b] ]Average temperatures could plunge by 5 degrees C- for comparison, this is about the same difference as between the global average temperature today and during the last Ice Age, when Canada lay beneath 3000m thick glaciers. The resulting colder, snowier winters would require new infrastructure, damage crops & shorten the growing season.

Yes, the temperature increase doesn't sound like much, but the little ice age in europe, --1450 to 1850-- which saw wide fammins and stuff, was caused by a (global) fluctuation only about 2 degrees F. a tiny change can make a big difference.
That's because not all of the world warms up by 2 degrees. It's because some parts warm while other parts cool.
now... global cooling. I didn't know that was a separate theory from global warming. In very mundane terms, here's what happens.
greenhouse gases makes the earth warm up, which makes ice melt, which upsets the salitnity around the poles as well as the temperature. There is a worldwide thermohaline current (temperature-salt current... also called the great ocean conveyor) which basically regulates the world's climate... that would be affected by the changes in salt and temperature. If it is disturbed, it stops/slows down/whatever (there's evidence for the effects of it being messed up) and that causes an ice age in the northen hemisphere.

much more than 5 years... where the ... did you... *shuts up*
WAAAAAAY more than 5 years. ... *breathe Luis breathe...*
ok let me put it this way. rain. It's not about weather it's raining or not, what worries people is how fast it is raining, which causes flooding and stuff...and how WHY it is raining. If it's raining because of us and we can stop it, then obviously you should stop the flood before it starts. (I have a feeling people don't like my analogies...lol)[b said:Quote[/b] ]It's not about wether it has been warmer or colder before, it's how fast and why it is warming up, and it is warming up VERY fast and it's because of US.
[b said:Quote[/b] ]BOULDER, Colo. - Researchers in Colorado have made a startling discovery. Fish, apparently male, are developing female sexual organs. Scientists believe it's the result of too much estrogen in the water and they're finding estrogen in rivers across the country.
In Colorado's rivers and streams, scientists are waist-deep in ritual of the season, using electric currents to stun native fish to the surface where they're measured and checked. But what they discovered in the white sucker fish has got even veteran scientists concerned.
"I've done a lot of studies throughout my career which extends back to 1973," says research associate John Woodling. “This is the very first time that what I've found scared me."
"This fish has characteristics of both male and female," says Dr. David O. Norris of the University of Colorado, Boulder.
And scientists have found lots of them in three Colorado rivers, all of them downstream from sewage treatment plants.
In the Boulder Creek, female white suckers outnumbered males five to one and 50 percent of the males also had female sex tissue.
Researchers say the cause is too much estrogen in the water, a natural female hormone that is found in every sewer system. But also, they say, certain chemical compounds in detergents and soaps can mimic estrogen.
Barbara Biggs, of Denver's largest sewage plant, says most of the nation's sewage plants simply can't remove all the estrogen in the water.
"We're concerned about the effect on aquatic life, but we're also concerned about our ability to actually treat for these estrogens and estrogen mimickers," says Biggs.
Estrogen mimickers are believed to be caused by chemicals called nonylphenols, found in everything from paints and rubber to cosmetics and plastics. They are considered a possible cause of kidney, eye, liver and reproductive problems.
They’ve been banned in much of Europe and are under review in Canada, but are still common in America, where they are flowing out of sewage plants and into clean water flowing into America's rivers.
Government researchers recently found natural estrogens and estrogen mimickers in 80 percent of the streams they tested in 30 states.
"We would be ingesting those chemicals, would absorb them, and they would add to whatever natural hormones we already have in the body," says Dr. Norris.
No one is certain what the impact is on humans. But since finding evidence that estrogen may be turning male fish into female fish, scientists are now looking at what it means for the nation's drinking water.
In a state that prides itself on living in harmony with nature, this is evidence, say researchers, of a hormonal imbalance.
true... there's this stupid guy in the station I listen to that says environmentalists (as if every single one of them) want to outlaw flush toilets and stuff. Talk about stereotyping. He doesn't even mention why. he just says "Oh what an environmental disaster if people aspire to use flush toilets!!!"[b said:Quote[/b] ]AlphaWolf, It's all whether you get your information by real climatologists or right-wing radio talk show hosts.
