going on with our world weather.
Despite all the modeling of the atmosphere, we still do not know if the atmosphere could dramatically flip on us unexpectedly. In 1958 Dr. Frank Baxter and Richard Carlson were on a Bell Telephone series that included a special on climate. I watched it again on Youtube. What was amazing is how Dr. Baxter fleshed out ideas about climate change or warming even back then. We even had data suggesting what we are seeing today was plausible back then.
His premise was that technology could make contributions toward mitigating climate change, but could not do it all. And how many years later and we are still denying what we are doing. Back in the 1950's it was popular to talk about controlling the weather. And it was brilliant how Dr. Baxter warned that weather was so complicated that unintended consequences could happen that you would lose control of the situation if you experimented to brashly.
His ideas reminded me of the clip on "Fantasia" and the sorcerer's apprentice. Ignoring the present weather data makes me think of that apprentice in a way. Even though climate predictions talk about changes as far as 100 years down the road, it looks like we are seeing faster changes. The apprentice in the movie took a shortcut to disaster. We may be doing the same thing since we re now going backwards again. Look at the latest data,we are warming more every day,every week.
Romney's joke about global warming is absurd and grossly irresponsible as well as pathetic. If there is no planet that you can live on because you support trashing it, then families are irrelevant in his example Obama's earlier initiatives on renewable energy have now take an back seat to the debate. Romney essentially says he will effectively end all of them with his policies.
My sense of climate change conversation that is not being discussed is the "wishful thinking" that the long range forecasts are long range. Then again I think a lot of these climate scientists privately believe that we could be in for a serious flip into crisis. Politically they cannot discuss such a possibility because the crazies would be labeling them as "fear mongers".

(53,661 posts)They are told by demagogues that if they vote to restore to enforce their ancient family values on everyone and support Israel to the death, they alone, TheElect, will be spared. The rest of us can go to Hell as far as they're concerned, the sooner the better to bring the Messiah back.
The second are the Randians, who don't believe in the SuperNatural, they believe that with enough money they will take off on a private space craft or otherwise be protected from catastrophe, on their floating cities which are already in operation that will travel the seas and only dock for provisions like the pirates of old, or hide in expensive underground bunkers, also already in place. I think that Romney is among that group and is looking to the long view.
And then there are the beer swilling, flag waving Teabaggers who think nothing is ever going to change as long they do as they're told by the other two groups. You'll note that probably only the first two groups, despite their public pronouncements to the contrary, do know that something's afoot.

(10,602 posts)that warming or change that could be extreme would happen over a fairly long period of time. As an example ocean rise is talked about that a 3 inch rise would happen over 10 years. By flip I mean that there could be a 1 foot rise in a couple of years. Or that temps could get dangerously higher than they are now in just a year or two.
The fact that some event now are surprising scientists may be causing them to wonder if they couldbe wrong about their predictions.

(10,960 posts)I just wasn't sure about the phrase, but I'm hep to the possibilities for catastrophic positive-feedback.
Methane in tundra worries me the most right now.

(40,416 posts)Scientists are notably cautious. The cannot say anything that the data and their theories and models do not support. They are so used to having to account for every word in their claims, they are very reticent to go beyond the data.
The reason why they don't talk about flipping the atmosphere is that nothing they see indicated that will happen.
However, when you read between the lines of this year's climate press, it shows that the climate scientists are increasingly alarmed about the apparent acceleration of warming effects.
James Hansen is now claiming that the drought in the Midwest and other places around the world are a result of anthropogenic global warming. Two years ago, he would not have said that because "weather is not climate". The fact that climate scientists are changing their song on this is a big move in the dialog.
If they start talking about flipping, we will be in a huge amount of trouble.

(59,590 posts)As we reported two years ago, an international group of scientists, the Arctic Methane Emergency Group has been sailing into the Arctic waters around Norway and Russia to take samples of methane bubbling from ocean clathrates frozen methane deposits on the sea floor. Some of their findings, very preliminary, are now making their way into the blogosphere, but like many, we await peer-review published articles or discussion in the next IPCC report AR5 due in 2014, before we draw hard conclusions.
EDIT
Some arctic sea regions as large as one kilometer in diameter are indeed frothing from massive gas releases from previously frozen CH4 deposits. Beginning in 2010, Igor Semiletov of the Russian Academy of Sciences said his research team discovered more than 100 plumes, and estimates there are thousands over a wider area, extending from Russian mainland to East Siberian Arctic Shelf. Earlier we found torch-like structures, but only tens of meters in diameter. This is the first time we found continuous, powerful, impressive seeps more than 1,000 meters in diameter. Its amazing. We carried out checks at 115 stationary points and discovered methane of a fantastic scaleon a scale not seen before, Semiletov said.
In our March 2010 post, Various Bubblings, we wrote: "Of course, as we have noted here before, warmer oceans, methane from permafrost and clathrate bubblings are all tipping points that accelerate climate change and are multiplicative - 2 or 3 orders of magnitude times anthropogenic emissions, once their threshold is crossed. Earth, meet Venus. The toxic gas fireballs rolling across Kansas, destroying and poisoning everything in their path, are described in Peter Wards book, Under a Green Sky. As Wallace Broecker says, The climate is an angry beast, and we are poking it with sticks. Atmospheric CH4 concentrations have risen more in the past 4 years than in the previous 20. Methane has a much shorter lifespan in the atmosphere than CO2, but it is 50 to 70 times (in the short term 100x) more potent as greenhouse gas. It doesnt go away when it decays, either. It oxidizes into CO2.
EDIT
A recent item from New Scientist highlighted the clathrate issue but unfortunately provided more smoke than light. The August 17 report described research led by Graham Westbrook of the University of Birmingham and Tim Minshull of the National Oceanography Centre, Southampton (Geophysical Research Letters, DOI: 10.1029/2009GL039191). Their team sailed into the west of the Svalbard archipelago, which lies north of Norway, where they found CH4 plumes being heated by the West Spitsbergen current, which has warmed 1 °C over the past 30 years. The methane being released from hydrates in the 600 km2 area added up to 27 kilotons/year, which suggests that the entire hydrate deposit around Svalbard could be releasing 20 megatonnes a year. Globally, extrapolating to all shallow, cold ocean areas, that translates to around 0.5-0.6 GtC/yr, or about 10% of fossil fuel emissions.
