And climate is nearing dangerous tipping points.

Reducing emissions of the short - lived climate forcers black carbon and tropospheric ozone — soot and smog — has been identified by scientists as the most effective strategy to slow Arctic warming and melting in the near term, forestalling potentially irreversible tipping points such as the melting, while the world works to reduce emissions of GHGs.

In a wide - ranging December 2013 study, conducted to support Our Children's Trust, a group advancing legal challenges to lax greenhouse gas emissions policies on behalf of minors, Hansen called for a «human tipping point» — essentially, a social revolution — as one of the most effective ways of combating climate change, though he still favors a bilateral carbon tax agreed upon by the United States and China as the best near - term climate policy.

Our home planet is dangerously near a tipping point at which human - made greenhouse gases reach a level where major climate changes can proceed mostly under their own momentum.

«The climate is nearing tipping points,» the NASA climate scientist James E. Hansen wrote in The Observer newspaper of London.

... Earth's climate is nearing, but has not passed, a tipping point, beyond which it will be impossible to avoid climate change with far ranging undesirable consequences.

But the idea that the planet is nearing tipping points — thresholds at which change suddenly becomes unstoppable — has driven a wedge between scientists who otherwise share deep concerns about the implications of a human - warmed climate...

Near the shift or tipping points climate is theoretically very sensitive — away from those points not so much.

NEW YORK, New York, June 1, 2007 (ENS)- A stern warning that global warming is nearing an irreversible tipping point was issued today by the climate scientist who the Bush administration has tried to muzzle.

When the scientific community states that we are already locked into climate change in the near future because of the pollution we have already emitted, it is a logical conclusion to the idea of a «point of no return» or «tipping point».

RealClimate is wonderful, and an excellent source of reliable information.As I've said before, methane is an extremely dangerous component to global warming.Comment # 20 is correct.There is a sharp melting point to frozen methane.A huge increase in the release of methane could happen within the next 50 years.At what point in the Earth's temperature rise and the rise of co2 would a huge methane melt occur?No one has answered that definitive issue.If I ask you all at what point would huge amounts of extra methane start melting, i.e at what temperature rise of the ocean near the Artic methane ice deposits would the methane melt, or at what point in the rise of co2 concentrations in the atmosphere would the methane melt, I believe that no one could currently tell me the actual answer as to where the sharp melting point exists.Of course, once that tipping point has been reached, and billions of tons of methane outgass from what had been locked stores of methane, locked away for an eternity, it is exactly the same as the burning of stored fossil fuels which have been stored for an eternity as well.And even though methane does not have as long a life as co2, while it is around in the air it can cause other tipping points, i.e. permafrost melting, to arrive much sooner.I will reiterate what I've said before on this and other sites.Methane is a hugely underreported, underestimated risk.How about RealClimate attempts to model exactly what would happen to other tipping points, such as the melting permafrost, if indeed a huge increase in the melting of the methal hydrate ice WERE to occur within the next 50 years.My amateur guess is that the huge, albeit temporary, increase in methane over even three or four decades might push other relevent tipping points to arrive much, much, sooner than they normally would, thereby vastly incresing negative feedback mechanisms.We KNOW that quick, huge, changes occured in the Earth's climate in the past.See other relevent posts in the past from Realclimate.Climate often does not change slowly, but undergoes huge, quick, changes periodically, due to negative feedbacks accumulating, and tipping the climate to a quick change.Why should the danger from huge potential methane releases be vievwed with any less trepidation?

The scientific literature and recent observations — along with our ongoing lack of climate action — have long passed the worrisome stage (see the post last month «Greenland Ice Sheet Melt Nearing Critical «Tipping Point» «and links below).

Head of the SAP, Drew Shindell, talks about why a near - term climate goal is important, the main message the article aims to convey, why governments should adopt a near - term goal, and whether reducing near - term warming can prevent climate tipping points.
