The world is getting warmer, countering the doubts of climate change sceptics about the validity of some of the scientific evidence, according to the most comprehensive independent review of historical temperature records to date.

Scientists at the University of California, Berkeley, found several key issues that sceptics claim can skew global warming figures had no meaningful effect.

The Berkeley Earth project compiled more than a billion temperature records dating back to the 1800s from 15 sources around the world and found that the average global land temperature has risen by around 1C since the mid-1950s.

This figure agrees with the estimate arrived at by major groups that maintain official records on the world's climate, including Nasa's Goddard Institute for Space Studies in New York, the US National Oceanic and Atmospheric Administration (Noaa), and the Met Office's Hadley Centre, with the University of East Anglia, in the UK.

1. More science for the deniers to ignore?

It's not that they don't get it; it's that they don't want to admit it.

[Gman]

8. They don't really deny it anyway

Rhey're paid to deny it.

4. This will go a long way to shut the deniers up

It will put a hole in the Teabagger's meme about the conspiracy on the left to push climate change.

[Frisbee]

9. No it won't.

It should. But it won't.

22. Unfortunately,

you are correct.

7. I guess something good came out of the BP disaster.

Less hush money to buy off scientists willing to sacrifice their credibility to play defense for the petroleum industry.

[groundloop]

10. Ironically this study was partially funded by a Koch brothers foundation...

I just read another news report about this study posted on BBC news... "Funding came from a number of sources, including charitable foundations maintained by the Koch brothers, the billionaire US industrialists, who have also donated large sums to organisations lobbying against acceptance of man-made global warming."

Maybe, just maybe, the flat earth people will begin wake up.

11. My brother is a denier out of guilt. He flies the super rich

around in private jets, spewing an amazing amount of carbon into the air. He can't give up the junk, man.

[fascisthunter]

12. ha ha ha... they all look like fools. And as time goes on on people will wonder

who the idiot deniers were.

[Bandit]

13. Republicans generally don't deny it's getting warmer

They just say man can not possibly cause it. Man is just to insignificant to cause any such shift in the World's Climate...They obviously have never witnessed such phenomenon as SMOG.....

15. New climate study deals blow to skeptics

October 21, 2011

London (CNN) -- An independent study of global temperature records has reaffirmed previous conclusions by climate scientists that global warming is real.

The new analysis by the Berkeley Earth Surface Temperature project examined 1.6 billion temperature reports from 15 data archives stretching back over 200 years in an effort to address scientific concerns raised by climate skeptics about the data used to inform reports published by the Intergovernmental Panel on Climate Change (IPCC).

Researchers found "reliable evidence" of a rise in average world land temperatures of one degrees Celsius -- or 1.8 degrees Fahrenheit -- since the mid-1950s.

"Our biggest surprise was that the new results agreed so closely with the warming values published previously by other teams in the United States and the UK," professor Richard A. Muller, Berkeley Earth's scientific director said in a statement.

18. Climate study confirms what skeptics scoffed at: global warming is real

Source: Christian Science Monitor

A new climate study shows that since the mid-1950s, global average temperatures over land have risen by 0.9 degrees Celsius (1.6 degrees Fahrenheit), confirming previous studies that have found a climate that has been warming – in fits and starts – since around 1900.

Most climate scientists attribute warming since the mid-1950, at least to some degree, to carbon dioxide emissions from human activities – burning coal, oil, and to a lesser extent gas, and from land-use changes.

The latest results mirror those from earlier, independent studies by scientists at NASA's Goddard Institute for Space Studies in New York, the Hadley Center for Climate Prediction and Research in Britain, and the National Oceanic and Atmospheric Administration (NOAA).

These previous efforts, however, came under fire from some climate-change skeptics who said they had detected serious flaws in the analytical methods and temperature records the three groups used.

Ice chunks float in the Arctic Ocean as the sun sets near Barrow, Alaska. The Arctic is a thermostat against overheating and a barometer of change, but now its own protective ozone layer that keeps out damaging ultraviolet radiation has thinned to record levels, the U.N. weather agency has said.

23. I'm no skeptic, but if I may say this...........

Let's not forget the fearmongering which has occasionally happened on our side of the debate as well.
There were a few instances, from the IPCC report from January 2007, namely, "global warming is likely to continue for centuries" and
"Sea levels........will continue to rise for at least the next 1,000 years.".......or the popular belief that Earth might just turn into Venus. The reason I say this, is because extreme stuff like this tends to scare people off instead of helping them learn about A.G.W.

That said, global warming is still real, and needs to be dealt with, no matter what big oil and their buddies say. Let's just not forget to be critical of our side as well, when someone gets a little outta hand.

24. The two from the IPCC are valid

The effects of carbon dioxide to take centuries to fade, since it takes centuries for it to be removed from the atmosphere:

"We found that more than half of the added carbon dioxide was pulled from the atmosphere within 30,000 to 40,000 years, which is one-third of the time span previously thought," said Bowen, who also is a member of the Purdue Climate Change Research Center. "We still don't know exactly where this carbon went, but the evidence suggests it was a much more dynamic response than traditional models represent."

Bowen worked with James Zachos, a professor of earth and planetary sciences at the University of California, Santa Cruz, to study the end of the Palaeocene-Eocene Thermal Maximum, an approximately 170,000-year-long period of global warming that has many features in common with the world's current situation, he said.

"During this prehistoric event billions of tons of carbon was released into the ocean, atmosphere and biosphere, causing warming of about 5 degrees Celsius," Bowen said. "This is a good analog for the carbon being released from fossil fuels today."

And sea levels will rise over centuries, too:

Rising sea level in the coming centuries is perhaps one of the most catastrophic consequences of rising temperatures. Massive economic costs, social consequences and forced migrations could result from global warming. But how frightening are the times we are facing? Researchers from the Niels Bohr Institute are part of a team that has calculated the long-term outlook for rising sea levels in relation to the levels of greenhouse gases and pollution in the atmosphere using climate models. The findings appear in their recent article "Sea level projections to AD2500 with a new generation of climate change scenarios" published in the journal Global and Planetary Change.

"Based on the current situation we have projected changes in sea level 500 years into the future. We are not looking at what is happening with the climate, but are focusing exclusively on sea levels", explains Aslak Grinsted, a researcher at the Centre for Ice and Climate, the Niels Bohr Institute at the University of Copenhagen.



http://www.macroevolution.net/sea-level-changes-2.html

From the paper:

Here we use a physically plausible sea level model constrained by observations, and forced with four new Representative Concentration Pathways (RCP) radiative forcing scenarios (Moss et al., 2010) to project median sea level rises of 0.57 for the lowest forcing and 1.10 m for the highest forcing by 2100 which rise to 1.84 and 5.49 m respectively by 2500. Sea level will continue to rise for several centuries even after stabilisation of radiative forcing with most of the rise after 2100 due to the long response time of sea level. The rate of sea level rise would be positive for centuries, requiring 200–400 years to drop to the 1.8 mm/yr 20th century average, except for the RCP3PD which would rely on geoengineering.

OK, the "we'll become Venus" isn't accurate. But, as you say, that's just 'a belief', among a few people who don't read the science.
