And none of it has happened. Congrats your high priests are batting .000Oh, you "Poor clueless retard....are you able to" pull your head out of "your own ass or do you need help with that too?"No problem little silly person. Here are just a few for your enlightenment and my entertainement(sic).
Although it shouldn't take me by surprise anymore after all the times I've interacted with you on this forum, it does still startle me sometimes to realize just how extremely clueless and retarded you actually are, walleyed. I sort of assumed, I guess, that everyone who has anything to say about this would have some idea of what the phrase "tipping point" means in the field of climate change but, as usual, you're clueless about the actual meaning and apparently have some screwed-up half-witted and very mistaken idea of what it means. Hint: it's not some Green politician in Canada talking about the urgency of taking action. I was pointing out earlier that the calls for urgent action to curb carbon emissions and slow global warming were quite valid, in part because of the very real possibility that rising temperatures could trigger "tipping points/feedback loops that could potentially cause uncontrollable run-away global warming, possibly, for example, through the release of the methane under the permafrost or from the undersea methane clathrates." You came back with a garbled, rather incoherent and very delusional claim that "there have been many others [tipping points] extending far back into the dark ages of AGW "theory". That didn't make much sense but I invited you to list these supposed "many other" tipping points that you seemed to feel had already been passed. LOLOLOLOL. It's obvious now that you had no idea what the term means. So you come back with, first, an article about how "Scientists 'expect climate tipping point' by 2200". ROTFLMAO...."2200"....just exactly what I was saying about the possibility of future tipping points.....how did you think that a tipping point in 2200 is happening "far back into the dark ages of AGW"??? All the rest of your articles are just various politician and public figures warning that the world has only a limited time to act to reduce carbon emissions before potentially irreversible changes take place. Those warnings are quite true and, indeed, we may have already passed a tipping point without realizing it. You seem to be confusing the warnings about probable looming tipping points as if the warning were the tipping points. You silly retard.
The Wiki article below is OK for starters but for a more detailed look at tipping points, this is a good analysis:
Climate Tipping Points: Current Perspectives and State of Knowledge
Tipping point (climatology)
From Wikipedia, the free encyclopedia
A climate tipping point is a somewhat ill-defined concept of a point when global climate changes from one stable state to another stable state, in a similar manner to a wine glass tipping over. After the tipping point has been passed, a transition to a new state occurs. The tipping event may be irreversible, comparable to wine spilling from the glass: standing up the glass will not put the wine back.
Global warming proceeds by changing the composition of gases in the Earth's atmosphere by the emission of greenhouse gases such as carbon dioxide and methane. As warming proceeds it brings about changes to the natural environment which may result in other changes. For example, warming may begin to melt the Greenland ice sheet and/or West Antarctic Ice Sheet. At some level of temperature rise, the melt of the entire ice sheet will become inevitable, even though complete melting may not occur for millennia. Thus a tipping point may be passed without any immediately obvious consequences, nor any acceleration of the warming process. Carbon dioxide as of May 2012 makes up 396.18 ppm of Earth's atmosphere[1] and monitoring stations in the Arctic spring 2012 measuring more than 400 ppm of the heat-trapping gas in the atmosphere.[2] James E. Hansen said that this tipping point had already been reached in April 2008 when the CO2 level was 385 ppm. (Hansen states 350 ppm as the upper limit.) "Further global warming of 1°C defines a critical threshold. Beyond that we will likely see changes that make Earth a different planet than the one we know."[3] He has further suggested potential projections of runaway climate change on Earth creating more Venus-like conditions in his book Storms of My Grandchildren.
Scientists and other specialists continue to express concern about global warming and irreversible tipping points. They have used metaphors such as "the door is closing" and warned of global food and water shortages, hundreds of millions of people being displaced by rising sea levels, and storms becoming ever more frequent and severe worldwide.[4] Others have tried systematically to short-list large scale components of the Earth system that may be subject to tipping points, defining tipping points as a variety of phenomena, including the onset of positive feedback, hysteresis effects, and the possible effect of statistical noise at critical points.[5]
Examples
Lenton et al. highlights a number of tipping points, including:[5]
* Boreal forest dieback
* Amazon rainforest dieback
* Loss of Arctic and Antarctic sea ice (Polar ice packs) and melting of Greenland and Antarctic ice sheets
* Disruption to Indian and West African monsoon
* Formation of Atlantic deep water near the Arctic ocean, which is a component process of the thermohaline circulation.
* Loss of permafrost, leading to potential Arctic methane release[6] and clathrate gun effect
LOLOLOLOLOL.....my gawd, you're sooooo retarded you think warnings about probable future tipping points aren't real if none of them have happened yet. LOLOLOLOL,
Actually the accelerating loss of Arctic sea ice is a tipping point that has either passed or we're passing now. Also the release of methane from under the permafrost and from undersea methane clathrates has already begun so those feedback loops may already be happening.
