The impending political tipping point is evident in nationwide opinion polls and in the climate policies already embraced by more than 850 towns and cities and 32 states.

Climate scientists are interested in learning more about abrupt climate changes because they indicate that the climate system may have «tipping points.Climate scientists are interested in learning more about abrupt climate changes because they indicate that the climate system may have «tipping points.climate changes because they indicate that the climate system may have «tipping points.climate system may have «tipping points.»

Climate homeostasis has a quite wide stress margin built into it's design but once we go over those tipping points (it's like a few more of those ropes breaking)..

But for those of us who follow Hansen, Spratt, Monbiot, and many others in the tail of a much more serious climate change story: non-linear, with positive feedbacks, tipping points, time lags and thresholds, we need a much more robust and focused scientific consensus now, without waiting years for the next IPCC reports, in time to win the crucial 08 election because the solution must be now, global and America must be a leader.

The little bit # h might hang around for a decade for all I know, given that climate change will lead to more extremes and tipping points...

[More research needed] We may eventually reach a tipping point primarily caused by CO 2 and enter a non - linear climate response.

In the Arctic, the tipping points identified in the new report, published on Friday, include: growth in vegetation on tundra, which replaces reflective snow and ice with darker vegetation, thus absorbing more heat; higher releases of methane, a potent greenhouse gas, from the tundra as it warms; shifts in snow distribution that warm the ocean, resulting in altered climate patterns as far away as Asia, where the monsoon could be effected; and the collapse of some key Arctic fisheries, with knock - on effects on ocean ecosystems around the globe.»

Even the latter might in theory lead to tipping points with abrupt climate shifts, but based on paleoclimatologic history, these are far more likely to be in the same direction as the trends than in the opposite direction.

These tipping points could be ice sheets on Greenland and Antarctica melting permanently, global food shortages and widespread crop failures with more extreme weather, rising ocean temperatures and acidity reaching triggering a crash in global coral reef ecosystems, and warming oceans push the release of methane from the sea floor, which could lead to runaway climate change, etc..

that cloud response to warming acts similarly to the eye's iris, opening to let more heat radiate out to space as temperature rises and closing to hold more heat in as temperature falls, and generally supports the understanding that Earth's climate is self - regulating and therefore not prone to a «tipping point» or a «runaway greenhouse effect» or «catastrophic warming.»..

More substantial changes would be along the lines of «Exploring potential impacts of a 2C world using insights from paleo climate records, modern observations and climate modelling» or «Exploring the potential for tipping points in the climate system before 2C».

According to the climate scientists a few more years of inaction will take us irrevocably past one or more of the catastrophic tipping points I have mentioned.

But the science is at best equivocal, and more accurately nearly non-existent, for the second proposition that the climate is dominated by positive feedbacks and will run away once it reaches some tipping point.

With some scientists saying that the tipping point for devastating sea - level rise and other abrupt climate change events is only ten years away, fast - action climate strategies like the 2007 Montreal Protocol adjustment are critical to buying world leaders more time to negotiate a long - term post-2012 climate treaty.

If the climate were in fact chaotic, then the idea of a tipping point becomes more plausible.

Similarly, human - caused global warming is capable of pushing the climate past a tipping point where we enter a new climate regime, one far more disruptive than what we are used to.

James E. Hansen worded it a bit more cleverly and eloquently before US Congress in April 2007: «crystallizing scientific data and analysis reveal that the Earth is close to dangerous climate change, to tipping points of the system with the potential for irreversible deleterious effects.»

GCMs often play a conservative role as a counterpoint to speculation or idealized modeling regarding «tipping points» or abrupt climate change, in favor of gradual, more linear climate response to external forcing.
