Somebody better warn the polar bears. s gonna get dicey.

WASHINGTON – Scientists from around the world are providing even more evidence of global warming, one day after President Barack Obama renewed his call for climate legislation.
"A comprehensive review of key climate indicators confirms the world is warming and the past decade was the warmest on record," the annual State of the Climate report declares.
Compiled by more than 300 scientists from 48 countries, the report said its analysis of 10 indicators that are "clearly and directly related to surface temperatures, all tell the same story: Global warming is undeniable."
Concern about rising temperatures has been growing in recent years as atmospheric scientists report rising temperatures associated with greenhouse gases released into the air by industrial and other human processes. At the same time, some skeptics have questioned the conclusions.
The new report, the 20th in a series, focuses only on global warming and does not specify a cause.
"The evidence in this report would say unequivocally yes, there is no doubt," that the Earth is warming, said Tom Karl, the transitional director of the planned NOAA Climate Service.
Deke Arndt, chief of the Climate Monitoring Branch at the National Climatic Data Center, noted that the 1980s was the warmest decade up to that point, but each year in the 1990s was warmer than the '80s average.
That makes the '90s the warmest decade, he said.
But each year in the 2000s has been warmer than the '90s average, so the first 10 years of the 2000s is now the warmest decade on record.
The new report noted that continuing warming will threaten coastal cities, infrastructure, water supply, health and agriculture.
"At first glance, the amount of increase each decade — about a fifth of a degree Fahrenheit — may seem small," the report said.
"But," it adds, "the temperature increase of about 1 degree Fahrenheit experienced during the past 50 years has already altered the planet. Glaciers and sea ice are melting, heavy rainfall is intensifying and heat waves are becoming more common and more intense."
Last month was the warmest June on record and this year has had the warmest average temperature for January-June since record keeping began, NOAA reported last week.
And a study by Princeton University researchers released Monday suggested that continued warming could cause as many as 6.7 million more Mexicans to move to the United States because of drought affecting crops in their country.
The new climate report, released by the National Oceanic and Atmospheric Administration and published as a supplement to the Bulletin of the American Meteorological Society, focused on 10 indicators of a warming world, seven which are increasing and three declining.
Rising over decades are average air temperature, the ratio of water vapor to air, ocean heat content, sea surface temperature, sea level, air temperature over the ocean and air temperature over land.
Indicators that are declining are snow cover, glaciers and sea ice.
The 10 were selected "because they were the most obviously related indicators of global temperature," explained Peter Thorne of the Cooperative Ins ute for Climate and Satellites, who helped develop the list when at the British weather service, known as the Met Office.
"What this data is doing is, it is screaming that the world is warming," Thorne concluded.

*yawn*
Don't do that... It's contagious.
True, global warming is real. At least the article didn't call it anthropogenic warming.
Global warming isn't killing polar bears. Evil air planes are killing them. Haven't you seen them falling from the sky lately?
Why do we need scientists to confirm what we see with our own eyes?
Hurricanes are getting worse, the Ice is melting...a 3 year old can comprehend this.
not this again.
Hurricanes are not getting worse. They are just getting more media coverage.
The ice has melted before. The ice has refrozen before.
I think it's awfully arrogant to think humans have the capability to make the temperature of the earth rise or fall.
Cap and Trade and Carbon taxes are about controlling money and picking winners/losers in the economy, not about controlling the climate.
I did not say that we were responsible for the global climate changes that I do believe are happening. I agree that any human affect on them is minuscule, although I do believe our usage of all the fossil fuels is not helping the earth any...although I don't know that that would have a major impact on our climate other than our emissions playing a small role in ozone depletion perhaps.
That's the funny thing about RG's op, it never mentions the cause of warming.
100% of scientists agree that there will be significant cooling this fall.
Because out life is too short a time span. Those who think like that are really stupid.
Don't you think the increased CO2 makes plants grow better?
i don't remember too much about all the science i learned in middle school and i don't feel like Googleing CO2 and plants...
agreed. scientists only say the obvious which can never be wrong. for someone making a living off it, it's better to stick to the undeniable truths than to risk their rightness or repute trying something inventive that can be really good for our society.
If no other factors are present yes. When you include the added nitrogen in the soil, change in temperature, or increased precipitation then no.
But CO2 does not warm as much as people think. Most certainly not enough to change the precipitation much.
Can you prove me wrong?
I didn't think so.
You have quite the Ego Cobra...
How exactly did you come about it?
Added Nitrogen in the soil is bad?
You clearly don't have a ing clue about how plants/agriculture operates.
Earthquakes and other natural disasters do tend to seem worse simply because humans are spread over more of the planet, and more densely than at any time in human history.
As for the "its awfully arrogant" schtick: that is an emotional argument, not unsimilar to the kinds that liberals are often accused of using.
There is either scientific data to support it, or there isn't.
Pumping gigatons of greenhouse gasses into the atmosphere, at rates similar to periods of earths history with high levels of volcanic activity, is cause for reasonable concern.
The evidence for the earth getting warmer overall than it has recently been seems to be fairly conclusive.
The only thing we need to figure out is why, and what we should do about it, if anything.
Reasonably proving you wrong is not always a high bar to clear.
Getting you to admit you are wrong over your confimation bias is another matter.
Does anyone even dispute this?
This just in:
The planet gets hot!
It also gets cold!
Right now, it's getting hot again!
What?!?! It's getting warmer?!?! Quick! To the private jet! We must convene at an exotic location to discuss how we can fix this if we just give more money to the government!
Do you usually prove yourself right?
I don't think so.
