Clouds Tracking Further North Just as Predicted by the 'Warmists'.

Thanks to the Fossil Fuels Derivatives Beast.

The Fossil Fuels Derivatives Beast.

Yes, I'm using the Denialists' term for climate scientists and others concerned about global warming.  It ought to get the Denialists' goat to be proven wrong!  See below.

Now from the Washington Post, a new analysis of satellite photo records shows that over the past four decades, since 1983 in fact, the cloud and storm tracks have been adjusting their positions poleward.

‘The most singular of all the things that we have found': Clouds study alarms scientists

[A]ccording to leading climate scientist Veerabhadran Ramanathan — credited with discovering that chlorofluorocarbons, or CFCs, are actually a greenhouse gas, among other major findings — a new study this week showing that clouds already are shifting their distributions across the Earth, and in a way predicted by climate change models, stands out. And not in a good way. 
The study was led by Ramanathan’s Scripps Institution of Oceanography colleague Joel Norris, though Ramanathan said he was not involved in the work and didn’t know about it until shortly before publication. But Ramanathan said that the study basically confirms that there’s nothing to prevent the world from reaching the high levels of warming that have long been feared — except for our own swift policy actions, that is. 
“My reaction was, my goodness,” Ramanathan said. “Maybe the 4 to 5 degree warming, certainly we were all wishing there was some certainty that would make it go away. So I consider the findings of this paper, the data shows major reorganization of the cloud system.” 
This matters because clouds are fundamental regulators of how much solar radiation makes it to the Earth’s surface (rather than being reflected back to space by white cloud tops), and how much infrared or “longwave” radiation escapes back to space once again.

But you know, what really grinds my gears is that people are still saying that "our own swift policy actions" can "prevent the world from reaching the high levels of warming that have long been feared." How are we going to do that? According to Robertscribbler, "Current greenhouse gas levels — topping out near 408 parts per million CO2 (and 490 parts per million CO2e) this year — will need to fall in order to prevent 1-3 C of additional warming." We're approaching 2 degrees C above 1880s levels already -- and although the planet's temperature will probably retreat to give us a 1.2 deg C avearge for all twelve months this year -- Ramanathan is right that current CO2 / CO2e levels are going to ramp warming up to the 4-5 deg. C mark.  We'll need to reduce the CO2 / CO2e levels. How are we going to avert that? Plant lots of trees even as multiple demands are causing deforestation all over the planet?

We need clean fuels to replace fossil fuels now and wind and solar may not be enough. How are we going to do that?  It seems right now, despite their ongoing financial troubles (which may cause fossil fuel production to remorselessly decline by way of disinvestment over the next several years), the fossil fuel industries and their bought (mainly "conservative") politicians are in the catbird seat right now, driving our fossil fuel dependency and this whole climate mess!

And it looks like Nature had already opened her Pandora’s Box.

October 2015 temps of 1.28 C above 1880s levels…. That’s 64% of the allotted 2 C target. Worse when you compare it to the newly-agreed 1.5 C target from the COP21 conference.

[December 2014 through November 2015 temps of] 1.06 C Above 1880: Climate Year 2015 Shatters All Previous Records For Hottest Ever.

We knew it was going to be a record breaker. We knew that atmospheric greenhouse gasses in the range of 400 parts per million CO2 and 485 parts per million CO2e, when combined with one of the top three strongest El Ninos in the Pacific, would result in new all-time global record high temperatures. But what we didn’t know was how substantial the jump would ultimately be.
 
Today, the numbers were made public by NASA. And I hate to say it, but it’s a real doozy. Overall, according to NASA, Climate Year 2015 — the 12 month period from December of 2014 through November of 2015 — was 0.84 C hotter than NASA’s 20th Century Baseline. That’s 0.11 C hotter than previous hottest year 2014 and a full 0.21 C hotter than climate change deniers’ favorite cherry — 1998. In other words past record hot years are being left in the dust as the world is heating up to ever more dangerously warm global temperatures.

In any case, the current NASA Graph above is going to need some serious adjusting as the new global average for climate year 2015 is simply off the top of the chart. A new jump that gives lie to the increasingly obvious fake claim made by climate change deniers over the past two years that global warming somehow ‘paused.’
 
But aside from reality once again making the fossil fuel cheerleaders of the world (aka climate change deniers) look increasingly imbecilic, 2015’s new temperature increase is a visible sign of increasing climate danger. This year’s 0.84 C temperature departure above NASA’s 20th Century baseline is 1.06 C hotter than 1880s values. It’s a number just 0.44 C (or two more strong El Ninos) away from crossing the very dangerous 1.5 C threshold that nations of the world recently pledged to attempt to avoid at the Paris Climate Summit. It’s also a number more than halfway toward hitting the catastrophic 2 C warming threshold. Perhaps more ominously, Monthly temperature departures in October of 2015 hit a range of 1.06 C above the 20th Century baseline and 1.28 C above 1880s averages — shorter term ranges that are already coming close to testing the 1.5 C threshold.

And just how much of a percentage of 1.5 C of the COP21's agreed-to global warming target is 1.28 C above 1880s levels is? About 85%. Forget waiting for peak oil, peak natural gas and peak coal to occur if we want to avoid catastrophic climate change and even more bizarre global weirding -- business as usual warped by fossil fuel extraction peaks and declines will still yield an atmospheric CO2 content of about 550 ppm (CO2e would be worse), yielding an ECS temperature rise of 3 C and an ESS rise of 6 C over the space of a thousand years. In geological time, that means Near Term Human Extinction.
