Biggest jump ever seen in global warming gases
The global output of heat-trapping carbon dioxide jumped by the biggest amount on record, the U.S. Department of Energy calculated, a sign of how feeble the world's efforts are at slowing man-made global warming.

WASHINGTON — The global output of heat-trapping carbon dioxide jumped by the biggest amount on record, the U.S. Department of Energy calculated, a sign of how feeble the world's efforts are at slowing man-made global warming.
The new figures for 2010 mean that levels of greenhouse gases are higher than the worst case scenario outlined by climate experts just four years ago.
"The more we talk about the need to control emissions, the more they are growing," said John Reilly, co-director of MIT's Joint Program on the Science and Policy of Global Change.
The world pumped about 564 million more tons (512 million metric tons) of carbon into the air in 2010 than it did in 2009. That's an increase of 6 percent. That amount of extra pollution eclipses the individual emissions of all but three countries - China, the United States and India, the world's top producers of greenhouse gases.
It is a "monster" increase that is unheard of, said Gregg Marland, a professor of geology at Appalachian State University, who has helped calculate Department of Energy figures in the past.
Extra pollution in China and the U.S. account for more than half the increase in emissions last year, Marland said.
"It's a big jump," said Tom Boden, director of the Energy Department's Carbon Dioxide Information Analysis Center at Oak Ridge National Lab. "From an emissions standpoint, the global financial crisis seems to be over."
Boden said that in 2010 people were traveling, and manufacturing was back up worldwide, spurring the use of fossil fuels, the chief contributor of man-made climate change.
India and China are huge users of coal. Burning coal is the biggest carbon source worldwide and emissions from that jumped nearly 8 percent in 2010.
"The good news is that these economies are growing rapidly so everyone ought to be for that, right?" Reilly said Thursday. "Broader economic improvements in poor countries has been bringing living improvements to people. Doing it with increasing reliance on coal is imperiling the world."
In 2007, when the Intergovernmental Panel on Climate Change issued its last large report on global warming, it used different scenarios for carbon dioxide pollution and said the rate of warming would be based on the rate of pollution. Boden said the latest figures put global emissions higher than the worst case projections from the climate panel. Those forecast global temperatures rising between 4 and 11 degrees Fahrenheit by the end of the century with the best estimate at 7.5 degrees.
Even though global warming skeptics have attacked the climate change panel as being too alarmist, scientists have generally found their predictions too conservative, Reilly said. He said his university worked on emissions scenarios, their likelihood, and what would happen. The IPCC's worst case scenario was only about in the middle of what MIT calculated are likely scenarios.
Chris Field of Stanford University, head of one of the IPCC's working groups, said the panel's emissions scenarios are intended to be more accurate in the long term and are less so in earlier years. He said the question now among scientists is whether the future is the panel's worst case scenario "or something more extreme."
"Really dismaying," Granger Morgan, head of the engineering and public policy department at Carnegie Mellon University, said of the new figures. "We are building up a horrible legacy for our children and grandchildren."
But Reilly and University of Victoria climate scientist Andrew Weaver found something good in recent emissions figures. The developed countries that ratified the 1997 Kyoto Protocol greenhouse gas limiting treaty have reduced their emissions overall since then and have achieved their goals of cutting emissions to about 8 percent below 1990 levels. The U.S. did not ratify the agreement.
In 1990, developed countries produced about 60 percent of the world's greenhouse gases, now it's probably less than 50 percent, Reilly said.
"We really need to get the developing world because if we don't, the problem is going to be running away from us," Weaver said. "And the problem is pretty close from running away from us."

My understanding is that we're already in it- that the world is, in fact, a new place as a result of global warming. That doesn't mean we should just give up, party on and say "screw it". We can still do something to slow down the effects of climate change. Our use of carbon based energy is the main culprit- and that is only debated any more by those who have the most to lose (oil companies, etc) or good intentioned folks in extreme denial (no offense intended to any one).
There are groups working hard to make the changes necessary to slow the process down. Here's a list of groups actively working to raise awareness and make a difference:

It's true, those two countries are catching up with us. We're still the biggest polluters I'm afraid. Fortunately, the organizations that are working to combat global warming are international.

Yep i wish they were
but dont we teach our kids to do the right thing regardless of what their friends are doing.
I teach mine to lead by example.
and thats why im so stoked australia has put in one of the strongest carbon pricing plans in the world.
Polar Bears are going to disappears from parts of Canada.

yup ...
they are already resorting to cannibalism
Yet another species who's survivors will probably be delegated to zoos. If we don't start acting soon, we'll all be museum pieces.

I'd like to think it's not to late save them...this type of situation is not good for people...Churchill, Manitoba does fairly well with Eco tours...this will have a trickle down effect on this community and probably more as well. I'm starting to see how everything is interconnected...better late they never.

$50 billion a year dude ... cost to canada by 2020 due to global warming ... rising exponentially from there ...
