Sahel greening confirmed

Another paper has confirmed that the Sahel is greening. A team from South Dakota State University led by Armel Kaptué have looked again and confirmed earlier reports:

The predominance of increasing rain-use efficiency in our data supports earlier reports of a “greening” trend across the Sahel. However, there are strong regional differences in the extent and direction of change, and in the apparent role of changing woody and herbaceous components in driving those temporal trends.

That's (yet another) one in the eye for Desmog's (alleged) debunking.

Interesting to note that Desmog’s highly-loaded debunking did attract a certain amount of scepticism: “Well of course it's nonsense to say the greening of the Sahel is down to global warming – there hasn't BEEN any global warming for 18 years.” (Punksta)

Perhaps even the dahlings of the AGWistas are losing some of their fan-base.

This represents a major problem for the Green Blob. Mother Earth is so enamoured with the colour green, that forces more powerful than anything previously thought possible by the Green Blob, are causing brown bits of the planet to turn green, when the Green Blob have decreed they shall be brown, and stay brown, until mankind repents of the sins invented by the Green Blob. This is so unfair for the Green Blob, who have spent billions of other peoples money fabricating this rubbish, it seems like a complete waste of time and money.

Few things make the Green Blob happier than salivating over mass extinction events. They need something to be happy about before Paris. News like this is not helping.

Charlatan psychos and pshrinks who dabble in paranormal climate science, will soon be offering lucrative rehabilitation courses for the disillusioned practioners of fraud, now looking to rebuild their livelihoods, at the expense of others.

Are Middle Eastern Plants Climate Change Deniers?

It seems that humans aren't the only ones capable of ignoring climate change. Middle Eastern plants, too, are denying its existence, as new research shows the region's vegetation is defiant and able to withstand more than seven years without water.

Friday, 8 August 2008
The IPCC predicts more rain overall this century in many parts of the tropics and towards the polar areas with declines in middle latitudes such as the Mediterranean basin, southern Africa and many parts of Australia.

Less rain = more rain ...

What the betting that one of the next claims to come out is that plants will become too used to higher levels of CO2 and be unable to cope when CO2 drops again? Or that they'll too greedy and overshoot 288ppm and cause an iceball Earth because of a lack of CO2.

The entire bandwagon of manmade warming rests on the facile pretence that natural variation can be ruled out because the climate charlatans cannot ascribe a cause for it but whenever their doom and gloom scenarios are contradicted by reality they suddenly find some natural variability of unknown cause to excuse their inadequacy and then say 'but it is set to reverse with global warming'. It is like arguing with children.

The greening of the Sahel is primarily because stomata size falls as [CO2] increases, so there is less evapo-transpiration. Then there is a positive feedback because increased ground cover reduces evaporation from the soil.

The same mechanism explains 30% increase of wheat yields worldwide, mostly down to the dry areas like Western Australia.

"The entire bandwagon of manmade warming rests on the facile pretence that natural variation can be ruled out because the climate charlatans cannot ascribe a cause for it"

Well put.

And there you have it in a nutshell!
I've just added that to the Hall of Fame.

Well, not that I am looking forward to some potentially harsh winters here in the UK, perhaps, with the onset of the ElNino shift, the AMO, & now this, perhaps this could be the end of the current scare story, & they'll have to think of something else to frighten us all with, probably little green men from Mars! For me, where I come from, people who want to frighten & scare others so that they conform to their wishes & demands, are called bullies!!!!

Once again skeptics are right: We are not experiencing dangerous climate change Once again the climate catastrophe cult is wrong: Deserts are greening, not getting worse.
How much more money and time will be squandered on the pathetic fears and rent seeking of the cliamte consensus?

@ Hunter: "How much more money and time will be squandered on the pathetic fears and rent seeking of the cliamte consensus?"

The answer? Plenty! It's going to take a long time for the green blob to climb down without losing face, not that I think they care as they have no integrity or pride!

the "local differences and variations" etc , gives the lie that "CO2 warming" homogneuously "causes" more intense rain events, doesnt it ??

You cannot have it both ways, they will have to quickly derive yet another "explanative" theory to patch this up.

Life for a prog greenie pseudoscientist gets confusing I reckon, it explains their "problem of communication" a bit I guess

Right, the climate is complex enough that our meager understandings of it are loaded with cognitive dissonance. That is compounded by the need to pursue an alarmist consensus, and because skeptics are constantly pointing out the dissonance in the so-called 'consensus. Skeptics are also pointing the way to improved understanding, and diminishing dissonance.

I'm amused that Bill Clinton once called CO2 'plant food', but only once. I believe he couldn't resist the dig at Al Gore's goofiness, but also believe he found a dead horse in his bed.

"Oh, no! That's terrible news that the Sahel is greening. Now we'll have to find something else to blame on CO2" said every Green Fascist.

I refer you to my comment in Douglas Keenan's piece.

Neither does this "piece" appear to take into account the increased water use efficiency of plants at higher atmospheric [CO2].
E.g.New Phytologist (2013) 197: 544–554 "Elevated CO2 increases tree-level intrinsic water use efficiency: insights from carbon and oxygen isotope analyses in tree rings across three forest FACE sites"

In other words they are trying to spin a "good news" story into alarmist gloom and doom.
