Climate change 'tipping points' imminent

(Phys.org) —UC Berkeley's Tony Barnosky joined climate scientists this morning at a press conference at the National Academy of Sciences in Washington, D.C., to summarize a new report issued today focusing on the short-term effects of climate change and the need to monitor them closely.

"Our report focuses on abrupt change, that is, things that happen within a few years to decades: basically, over short enough time scales that young people living today would see the societal impacts brought on by faster-than-normal planetary changes," said Barnosky in an email. Barnosky is professor of integrative biology and a member of the Berkeley Initiative in Global Change Biology (BIGCB).

The report, "Abrupt Impacts of Climate Change: Anticipating Surprises," is available from the National Research Council, part of the National Academies.

Watch out for climate 'surprises,' scientists warn - CNN.com

(CNN) -- The long, slow process of climate change may trigger "surprise" shifts that could threaten human communities in years or decades, researchers from the National Academy of Sciences warned Tuesday.

In a 200-page report, the scientists call for an early-warning system that would watch bellwethers like Midwestern aquifers, Antarctic ice sheets and tropical coral reefs for signs that a "tipping point" is coming. Accelerated environmental changes can already be seen in the loss of Arctic sea ice and bigger wildfires since 1980, the authors said.

"A lot of these things require not only monitoring what's going on out there in the natural world as well as monitoring what we do in the human-built environment as well; how much dollar-wise do we have at risk?" said Jim White, who led the committee that produced Tuesday's report.

The committee didn't calculate the cost of establishing an early climate warning network. But even in a time of tight budgets, White said, the cost would be "trivial compared to the cost of the assets at risk."

Media's global warming fail When the Pacific Ocean altered rainfall patterns around the world, the subsequent climate shifts coincided with the fall of Mayan civilization, researchers said, occurring after the peak in A.D. 900. The Tang dynasty also fell during a time of dryness associated with the same event coinciding with the end of Mayan civilization. Dunhuang was a vital command post on the Silk Road during China's Tang dynasty, which ended about A.D. 906. Based on tree rings in Vietnam, scientists determined that there were serious droughts before the collapse of the Angkor kingdom. There are more than 100 temples in the area built between A.D. 802 and 1220. The area shares the same climate as Angkor, which collapsed about the same time. The Akkadian empire -- about 2350 to 2150 B.C. -- collapsed around a time of dryness, as indicated by continental dust that was blown from Mesopotamia into the Gulf of Oman. This is a region where conflicts may have been associated with El Nino Southern Oscillation, according to researchers.

"We have trillions of dollars of infrastructure in cities along the coast alone," said White, a geochemist and paleoclimatologist at the University of Colorado. When a bank wants to protect the money in its vaults, "You don't crab about how much the cameras cost," he said.

But, he added, "at a time when we should be understanding more and observing more about our environment, we're actually observing less."

The idea of long-term climate change driven largely by the use of fossil fuels, which release heat-trapping carbon dioxide emissions into the atmosphere, is controversial politically but accepted as fact by most researchers. The concentration of heat-trapping carbon dioxide hit a concentration unseen since prehistoric times at the benchmark Mauna Loa observatory in May, and scientists reported in 2012 that the ice sheets covering Greenland and Antarctica were losing mass at an accelerating rate.

Tuesday's report states that there's a high risk of increased extinctions of land and sea life and the disappearance of the Arctic icecap in summers within this century. There's a moderate risk of increased heat waves, a decline in ocean oxygen levels and rapid changes to ecosystems that would threaten food and water supplies, the scientists note. Watching for those symptoms would give communities that depend on those ecosystems the ability to adapt, White said.

And there's a "probably low" but unknown risk that warmer rising seas could undermine the ice sheet that covers western Antarctica, raising average sea levels far more and more quickly than the roughly 1 meter (3 feet) they're now projected to increase by 2100. That would make it much harder for coastal cities like Miami, which is already seen as the U.S. city most vulnerable to climate change, to adapt in time.

"Warm water, as one could imagine, is the enemy of ice, and we don't monitor ocean currents and ocean temperatures near the ice sheet nearly as much as we should," White said.

Other feared effects -- such as the sudden release of large volumes of methane from thawing Arctic tundra or the disruption of the Atlantic Ocean currents that carry warm water into the northern latitudes -- were given a low chance of occurring on a rapid scale. That's not to say that they won't happen, just that they're likely to happen gradually, White said.

Global average temperatures are up about 1.5 degrees Fahrenheit (0.8 degrees Celsius) since the 1880s, according to NASA. The United Nations has been trying to get member nations to reduce carbon emissions enough to limit warming to 2 degrees C (3.6 F).

But in a paper published the same day as the National Academy's report, NASA's former top climate scientist warned that a 2-degree increase would still inflict "irreparable harm" on future generations.

"These growing climate impacts, many more rapid than anticipated and occurring while global warming is less than 1 degree C, imply that society should reassess what constitutes a 'dangerous level' of global warming," James Hansen, now the head of the climate science program at Columbia University in New York, wrote in the online, peer-reviewed scientific journal PLOS One.

Continuing to burn fossil fuels at today's rates "would be an act of extraordinary witting intergenerational injustice," Hansen and his colleagues concluded.

Just kidding. You're both.

So you have no response to my posted article. I thought that might be the case.

I thought you knew by now, Abe.

Anti-science retards like ol' DaveDumb and the kookster will never give you a rational response to any possible scientific studies or information that you might post. They live in a bizarre fantasy world totally disconnected from reality.

Ignorant and absurd drivel and moronic cartoons are pretty much the best you can expect from cretins like those two, and the rest of the denier cultists aren't much different.

 

[HenryBHough]

Come on lets stop this shit.

You have the power to do just that.

Unplug your computer.

If it's a laptop, take the batteries out.

Only you can save the planet!

You never seem to any clue as to what everybody else is actually talking about, Huffer. It's a shame you're so ignorant, confused and retarded.

Got it.

You can't find the power cord.

You could try the manual but the cost of a remedial reading course to cope with it would likely be greater than that of the computer itself. Maybe we can take up a collection!

I think we should dump millions of tons of reflective particles in the air from commercial airliners to reflect the sun rays!

"Our report focuses on abrupt change.."

Change is good. If everything were always the same, people would get suspicious and start conspiracy theories.

It is amusing to watch academics back track on previous absolute positions about the results of their dynamic model studies.

 

[HenryBHough]

We can solve so much of so simply.

Remember those machines that used to make filter tips for cigarettes?

Adjust 'em to make them larger and shove them up cattle's asses.

But so the used ones don't go to waste, dry them, flatten them and box them up as breakfast cereal for health food obsessed, politically correct liberals.

 

[R.C. Christian]

Cattle must be destroyed. Cattle cause Methane. Methane bad, cattle bad.

Yup! We're almost to the point where no one at all buys into the AGW myth.

Is that the tipping point you refer to?

Yes, we must stop climate from changing.

We need Chicago to stay 12 degrees, year round.
