Why COP 21 Is a Fraud... Last Part.

Well I've exposited why COP 21 is a fraud, and let John Michael Greer have his say, mainly because it's targets for emissions curbs are non-binding, because there is no commitment to not continue using fossil fuels, and because countries are going ahead with fossil fuel reserve exploitation and other fossil fuel energy projects anyway. Another reason comes from an old study: that the present (2005 = +/-376 ppmV) overburden of Carbon Dioxide in the Atmosphere will break the 2.0 degrees C (3.6 F) limit anyway.
Atmospheric CO2 is rising around 1.9 ppm per year, up from a pre-industrial level of 280 ppm by volume.

The observed increase in the concentration of greenhouse gases (GHGs) since the preindustrial era has most likely committed the world to a warming of 2.4°C (1.4°C to 4.3°C) above the preindustrial surface temperatures. The committed warming is inferred from the most recent Intergovernmental Panel on Climate Change (IPCC) estimates of the greenhouse forcing and climate sensitivity. The estimated warming of 2.4°C is the equilibrium warming above preindustrial temperatures that the world will observe even if GHG concentrations are held fixed at their 2005 concentration levels but without any other anthropogenic forcing such as the cooling effect of aerosols. The range of 1.4°C to 4.3°C in the committed warming overlaps and surpasses the currently perceived threshold range of 1°C to 3°C for dangerous anthropogenic interference with many of the climate-tipping elements such as the summer arctic sea ice, Himalayan–Tibetan glaciers, and the Greenland Ice Sheet. IPCC models suggest that ≈25% (0.6°C) of the committed warming has been realized as of now. About 90% or more of the rest of the committed warming of 1.6°C will unfold during the 21st century, determined by the rate of the unmasking of the aerosol cooling effect by air pollution abatement laws and by the rate of release of the GHGs-forcing stored in the oceans. The accompanying sea-level rise can continue for more than several centuries. Lastly, even the most aggressive CO2 mitigation steps as envisioned now can only limit further additions to the committed warming, but not reduce the already committed GHGs warming of 2.4°C.

I repeat the finding of the above study, that with the 2005 Atmospheric content of about 376 ppmV CO2, there is already 2.4 C (4.3 F) degrees of global warming baked in the cake. We've gone through about half that now.

And even what global warming we've passed through so far appears to be just too much to avoid global weirding and dangerous climate change, what with the Christmas weekend storms (with tornadoes) that left so much rain on the Mid-South and Great Plains that the Mississippi will be experiencing historic levels of flooding over the next few weeks. The place to watch may not St. Louis, or New Orleans, but the Old River Control Structure that keeps the Mississippi from escaping down the Atchafalaya River. That structure almost failed in the famous 1973 floods. Dr. Jeff Masters of Weather Underground reports that the NWS River Forecast Center predicts that "the Mississippi River would crest at Red River Landing, where the Old River Control Structure is located, on January 19. The predicted crest of 62.5' is just 0.9' below the all-time record crest of 63.39' set on May 18, 2011."

The global weirding we've experienced so far has wrecked the climates of the Arctic, as Robertscribbler reports:

Record Hot Arctic: NOAA’s 2015 Report Card Shows Signs of Failing Climates

by Robertscribbler,  21 December 2015

In NOAA’s most recent annual Arctic Report Card, the records just keep falling as the litany of global warming related events appearing throughout the far north continued to crop up with ever-more dizzying frequency...

NOAA’s Arctic report is a stark expose of the state of the Arctic climate. What we view now is a system undergoing a rapid and dynamic transition from its previously stable state to something that is entirely new and alien to human civilization.

The 12 month period of October 2014 to September 2015 was the hottest one year time-frame since record keeping began for the Arctic back in 1900. As a result of these record warm temperatures, Arctic sea ice during the Winter hit its lowest maximum extent ever seen. Summer sea ice extent was likewise greatly reduced hitting its 4th lowest extent ever recorded. Old, thick sea ice which represented 20 percent of the ice pack in 1985, has precipitously declined to a mere 3 percent of the ice pack today. Snow cover also took a hit, declining to its second lowest extent on record during 2015 and striking a range of 50 percent below the typical average for the month.

Overall warming of the Arctic is at a much more rapid pace than the rest of the world. This accelerated pace of warming is due, in large part, to loss of snow and sea ice reflectivity during the Spring and Summer months. As a result, more heat is absorbed into dark land and ocean surfaces — a heat that is retained throughout the Arctic over longer and longer periods. And, though NOAA doesn’t report it in the above video, overall higher concentrations of greenhouse gasses like methane and CO2 in or near the Arctic region also contribute to a higher rate of warming (see NOAA’s ESRL figures). In a world that is now rapidly proceeding beyond the 400 ppm CO2 and 485 ppm CO2e threshold, this is exactly the kind of Northern Hemisphere polar amplification we would expect to see.

And this record hot Arctic, acting in concert with El Nino and The Blob (record warm water and high pressure air out in the Pacific), is spawning a wicked frontal system possessing multiple lows, hurricane-force winds and an area the size of small continents (examples.: Europe, Australia). This system is just one of the first h'ors d'oeuvres in the just-commencing multiple course meal of dangerous climate change that Jim Hansen called The Storms of My Grandchildren. I do not expect these storms to cease until the overheating of the planet finally reaches an equilibrium a thousand years from now.
Warm Arctic Storm To Hurl Hurricane Force Winds at UK and Iceland, Push Temps to 36-72+ Degrees (F) Above Normal at North Pole

by Robertscribbler, 27 December 2015

We’ve probably never seen weather like what’s being predicted for a vast region stretching from the North Atlantic to the North Pole and on into the broader Arctic this coming week. But it’s all in the forecast — an Icelandic low that’s stronger than most hurricanes featuring a wind field stretching over hundreds and hundreds of miles. One that taps warm tropical air and hurls it all the way to the North Pole and beyond during Winter time. And it all just reeks of a human-forced warming of the Earth’s climate…
Sunday afternoon, a powerful, hurricane force low pressure system was in the process of rounding the southern tip of Greenland. This burly 960 mb beast roared out of an increasingly unstable Baffin Bay on Christmas. As it rounded Greenland and entered the North Atlantic, it pulled behind it a thousand-mile-wide gale force wind field even as it lashed the tip of Greenland with Hurricane force gusts. To its east, the storm now links with three other lows. Lows that are, even now, drawing south-to-north winds up from a region just west of Gibraltar, on past the UK, up beyond Iceland, over Svalbard, and into the Arctic Ocean itself.
GFS forecasts predict a storm bombing out between 920 and 930 mb over Iceland by Wednesday. It’s a storm that could rival some of the strongest such systems ever recorded for the North Atlantic. But this storm’s influence is unique in its potential to shove an unprecedented amount of warm air into the Arctic. A warm storm for the Arctic Winter time.
Over the next few days these three lows are predicted to combine into a storm the likes of which the far North Atlantic rarely ever sees. This storm is expected to center over Iceland. But it will have far-reaching impacts ranging from the UK and on north to the pole itself. As the lows combine, GFS predicts them to bomb out into an unprecedentedly deep low featuring 920 to 930 mb (and possibly lower) minimum central pressures by this coming Wednesday. These pressures are comparable to the very extreme storm systems that raged through the North Atlantic during the Winter of 2013. Systems that featured minimum pressures in the range of 928 to 930 mb.
It’s worth noting that the lowest pressure ever recorded for the North Atlantic occurred in the much further southward forming Hurricane Wilma at 882 mb.
By early Wednesday, temperatures at the North Pole are expected to exceed 1 degree Celsius readings. Such temperatures are in the range of more than 40 degrees Celsius (72 degrees Fahrenheit) above average.
And it's not just storms we have to worry about. It's also wicked bad droughts, like the one California recently experienced for the past four years -- and is still experiencing to some degree and in some areas.

A study was made for California’s millions of trees and it looks like the drought stress on them has been extremely bad: bad enough to cause about half of them to be so water stressed that they’ll die if the drought comes back.

California’s Future Is in the Hands of Its Dying Trees
Newsweek – By Zoë Schlanger 29 December 2015

The past four years of punishing drought have badly hurt California’s forests. Rain was scarce, the days were too hot, and this year’s wildfire season was the worst anyone has seen in years, burning up nearly 10 million acres across the West. For the first time, a team of researchers has measured the severity of the blow the drought dealt the trees, uncovering potential future destruction in the process. The resulting paper, published Monday in the Proceedings of the National Academy of Sciences, is a rich visual testament to just how much California needs its trees and how close the state is to losing 58 million of them.

A team at the Carnegie Institution for Science, led by ecologist Greg Asner, used a laser-guided imaging tool, more properly referred to as high-fidelity imaging spectroscopy (HiFIS), mounted on a plane to sweep over California, taking snapshots that revealed how much water content the forest canopy had lost over time. In these images, the trees that appear red and orange are severely depleted of water. Light trees, in shades of tan, are trees under “drought stress” resulting from this past year’s dry season. The trees colored in blue are “doing OK,” Asner says.

In total, the team found that up to 58 million large trees, shown in red, have been heavily impacted by the drought. If the drought recurs, or if the El Niño keeps the heat turned up in the region, Asner says these trees will likely die. New tree growth would also be suppressed, leaving room for shrublands or grasslands to take over, destroying the current ecosystem of plants and animals entirely. That poses a host of new questions for wildlife management and conservation. “For example,” Asner says, “if we’re going to lose habitat, what does that mean for bear populations?”


Of course, it's not just California. As Colorado Bob said to me today, Every tree everywhere is under attack. All over the world.

And this, at only half of the 2.4 degree Celsius temperature rise (+4.3 F) that we've already baked into the cake of Anthropogenic Global Warming. And Peak Oil won't reduce it, not one iota!
