Desertification cancelled: Climate Change won’t make the deserts grow

After a thousand headlines told us Climate Change would make deserts grow, a new study suggests it won’t. It’s a finding that shocks no one who knew that climate models have no predictive skill with rainfall, and that a warmer world means higher global precipitation. Plus there’s the awkward clue that for the last forty years the arid regions of the world have been getting greener instead of more deserty.

Looks a bit different?

The top map (below) shows the deserts expanding — but that’s the old predictions which are based only on “atmospheric data” like temperature and rainfall. The bottom map is the new work which uses soil and vegetation data too. Red means growing deserts. Blue means shrinking.

Remember, all contradictory conclusions are based on expert opinions using worlds best practice and done by Nobel-Prize-winning people. Shame about all the farmers and investors making decisions based on junk models.

Deserts were expanding until experts got a better model.

 

The new study is based on modeling too so it is still wrong, but less useless than previous studies.

The hugely different forecasts show how vaporously thin the past doom and gloom was, and how so many […]

Settled! Global Warming and the pause, caused by changes in cloud cover, not CO2

That’s it: It was 4% cloudier in 1985, then roughly the same after 2000 — that’s the Pause and the Cause

A new paper in Russian, by OM Pokrovsky, shows that global cloud cover decreased markedly from 1986 to 2000. This is a very large decline in terms of the planetary atmosphere. Pokrovsky uses ISCCP satellite data (the “International Satellite Cloud Climatology Project” — a US program). It’s the best cloud data there is. The effects of clouds are so strong that most of the differences between IPCC-favoured-models comes from the assumptions the models make about clouds. Cloud feedbacks are the “largest source of uncertainty”. [IPCC, 2007]

Clouds cover two-thirds of the Earths surface, reflecting around 30% of the total energy from the Sun back to space. A small change in cloud cover can easily warm or cool the planet, like a giant pop-up shade-sail.

This, on its own, explains all the warming that occurred from 1986 – 2000. It explains the pause. We don’t know why clouds decreased, but we know it wasn’t due to CO2, which kept rising relentlessly year after year, and even faster after the turn of the century.

Something else is driving cloud formation, or […]

It’s a tech-wreck: models now use human moods and fashions as a climate forcing

How many climate marches does it take to stop a storm?

A new climate model includes “social processes” to predict the climate. They expect the fashionality of hybrid cars or solar PVs will help predict the future climate. So serious researchers are now feeding their models with trends in human behaviour. Though there’s no sign climate models may use the million-mile-an-hour solar wind, nor changes to the solar magnetic field that’s bigger than Earths orbit. They’re also not using solar spectral changes, but who cares about the odd quadrillion joules of ultra violet fritzing or not-fritzing our ozone layer? So much better to track twitter trends on solar panels instead.

The fixation on CO2 is so obsessive compulsive it’s practically a science cult. This kind of work puts the psycho in psychology.

Years from now when everyone agrees it was The Sun, historians are going to fish deep from this well of academic obsession:

New global warming model highlights strong impact of social learning

Human behavior influences a wide range of complex systems, including ecosystems, social networks, and the climate. Moreover, these systems impact human behavior, creating a feedback loop. Human behavior is […]

Climate Models are a Joke

An update on the graph that is death to climate models

Good people of Earth are spending thousands of billions of dollars to prevent a future predicted by models that we know don’t work. The debate is over, climate spending is an unscientific, pagan, theological quest to change the weather. Just another iteration of what Druids and Witchdoctors have been promising for eons. Don’t expect the vested interests that profit from this Golden Climate Gravy Train to tell you this.

The top 23 global coupled climate models don’t understand the climate and can’t predict it. Our CO2 emissions are accelerating, the effect should be amplifying, but millions of weather balloons and satellites that circle the Earth 24 hours a day show unequivocally that the models are wrong.

Latest, belated admission the models were “too hot” is all PR and politics, nothing to do with science

Spot the political PR paper pretending to be science: the global carbon budget just got a whopping — four — times — bigger, but instructions on how to follow the carbon religion are 100% identical.

It’s become too obvious to everyone that the climate models have been complete failures. Thus, the global leeches were facing a crisis as their credibility and motivation drain. So the new paper in Nature Geoscience is just a retweak of the models to produce a number that isn’t so mock-worthy. There is no scientific reason offered, no new understanding of the climate. No one is even pretending that these modelers can explain the way our climate works any better than they did last year when they were utter failures. It’s all a charade. There is no honesty here — if there was, they’d admit the skeptics are years ahead of them.

The new paper is just about “staying the game”, a desperate injection to keep the dying movement alive. All the political messages remain untouched. It’s got everything to do with PR and nothing to do with science.

The numbers change (and nobody ever cared about them anyway) but PR meme is a carbon copy: […]

Former NASA GISS climate scientist reveals incompetence, junkets, best model called “jungle” of code

Dr Duane Thresher who worked seven years at NASA GISS describes a culture of self serving rent-seekers, mismanagement and incompetence. These are the top experts in the climate science field that we are supposed to accept without questioning. Those who say they are working to “save the planet” care more about their junckets than they do about the data or their “best” model.

NASA GISS’s most advanced climate model is run from the Goddard Space Flight Center (GSFC). Thresher recounts a story from someone on the inside:

“NASA GISS’s climate model — named Model E, an intentional play on the word “muddle” — is called the “jungle” because it is so badly coded.” I know this to be true from my own extensive experience programming it (I tried to fix as much as I could…).

Thresher writes about how the team was happy to take taxpayer funds and spend it on unnecessary conferences which were “loads of fun” while they scrimped and saved on things like data security and incompetent tech staff. Secretaries and mail boys were hired for jobs they were not qualified for. At one point data was lost when exposed plumbing leaked in the computer […]

CO2 causes cold-hot East-West split climate change in the USA!

Somewhere in the world, a whole town is missing their tea-leaf readers.

The Physics tells us (practical beats us over the head) that more CO2 will mean warmer nights. It is a 97% certified mantra that warm nights are a fingerprint of man-made global warming.*

Well don’t look now, but CO2 causes cold nights too (and get this… on the East Coast).

Extreme-weather winters are becoming more common in US

Recent years have seen a dramatic increase in the simultaneous occurrence of extremely cold winter days in the Eastern United States and extremely warm winter days in the West, according to a Stanford-led study published in Journal of Geophysical Research Atmospheres. Human-caused emissions of greenhouse gases are likely driving this trend, the researchers report.

Used to be that single seasons were “weather” and thirty year trends were “science”– now all they need is a single repeated season and half a country:

“Looking back at temperature data from the past 35 years, we’ve found that in fact 2013-2014 and 2014-2015 did have the biggest difference in winter temperature between the East and West.”

This is pretty freaky — can you imagine how smart these guys must […]

Experts “surprised” to discover what skeptics have known for years: world has been warming for 200 years

For years, skeptical scientists have been pointing at data that showed the the world started warming somewhere from 1700 – 1820. This has been known from glaciers, sea level studies, ice cores, boreholes, ocean heat content estimates, and more proxies than any climate-nerd cares to name.

Finally, expert climate modelers are “surprised” to discover this:

“…their study had detected warming in the Arctic and tropical oceans from around the 1830s, just 80 years after the Industrial Revolution started in England. “It was an extraordinary finding,” she said. “It was one of those moments where science really surprised us. But the results were clear. The climate warming we are witnessing today started about 180 years ago.”

How many grant dollars did it take to figure out what skeptical scientists have been saying for years?

The correlation with global temperatures and actual numerical human emissions is abysmal, so now Abrams et al ignore the numbers and appear to suggest that “The Industrial Revolution” itself started the warming — as if the mere invention of the steam engine heated the world.

[Dr Abram] said the study attributed the gradual warming to an increase in greenhouse gas emissions linked […]

Another climate model paper in Nature misses a whole class of feedbacks

It’s always the same. A new paper adds one more magical fine-tuning-cog to the models and promises “more accurate predictions”. There are a million small cogs we can add and it takes years to show they don’t deliver. These wheels can spin forever. The real climate machine has a whole extra exhaust pipe to which the models are blind.

Why some climate processes are more effective at warming Earth

Conventional models assume increasing atmospheric CO2 warms the surface, then apply the feedbacks to the surface warming. But if feedbacks start up in the atmosphere instead, everything changes.

The assumption (bolded below) is the problem —

There are many processes which affect the surface climate: changes to the sun’s activity, to the cloud cover, precipitation patterns, or soil water content to name just a few. Currently climate scientists relate these processes by looking at how much they change the energy budget, described by perturbations in the radiative forcing. The existing assumption is that if a given process introduces a certain radiative forcing, then there will always be the same response in the surface air temperature. However, this assumption doesn’t hold for the temperature response […]

Monckton: IPCC climate models speeding out of control compared to real world

Christopher Monckton reminds us of just how badly the “experts” have failed in the last 15 years, even including the recent hottest ever El Nino months. China bombed the atmosphere with record carbon “pollution” — worse than we thought. The world though, warms sedately at a mere half a degree per century. This is what 95% certainty looks like. — Jo

Introducing the global warming speedometer

A single devastating graph shows climate panic was unfounded
