John Christy, director of the Earth System Science Center at the University of Alabama-Huntsville.John Christy is a climate scientist at the University of Alabama-Huntsville. Along with Roy Spencer, he developed the first satellite temperature record of the Earth. Skeptical about catastrophic anthropogenic global warming, he has been invited to speak before Congress several times. He is the director of the Earth System Science Center at UAH.
TATW: What would be the single piece of information that you would convey to people who have strong opinions about climate and little knowledge?
CHRISTY: A fundamental aspect of science is that when we scientifically understand a system, we are able to predict how the system evolves in time. The comparison of model output with observations indicates we have much less understanding than what is needed to predict it with any confidence. I…
“Kevin and I will keep (skeptic papers) out (of IPCC) somehow – even if we have to redefine what peer-review literature is” – Phil Jones | Climategate Emails
“As you know, I’m not political. If anything, I would like to see the climate change happen, so the science could be proved right, regardless of the consequences. This isn’t being political, it is being selfish.” – Phil Jones
If you think that the tampering of the earth’s temperature record, to fit the man-made global warming narrative, is another climate denier conspiracy theory, then read this Climategate email from the UK’s leading climate expert, Phil Jones, to the UK Met Office and officials…
NASA is constantly altering their historical data to create the appearance of a non-existent warming trend.
The NASA graphs are useful for politicians who want to raise taxes, and for insurance companies who want to raise premiums – but are worse than useless for scientists who actually want to understand the climate. They show the exact opposite of what is happening to the climate.
Even Naturehas acknowledged that the Pause is real, and that the models are missing something:
Average global temperatures hit a record high in 1998 — and then the warming stalled. For several years, scientists wrote off the stall as noise in the climate system: the natural variations in the atmosphere, oceans and biosphere that drive warm or cool spells around the globe. But the pause has persisted, sparking a minor crisis of confidence in the field. Although there have been jumps and dips, average atmospheric temperatures have risen little since 1998, in seeming defiance of projections of climate models and the ever-increasing emissions of greenhouse gases. […]
But none of the climate simulations carried out for the IPCC produced this particular hiatus at this particular time. That has led sceptics — and some scientists — to the controversial conclusion that the models might be overestimating the effect of greenhouse gases…
Germany’s wind and solar power generation came to a standstill in late 2013. More than 23,000 wind turbines ran out of wind and most of the one million photovoltaic systems ran out of sunlight. For a whole week, coal nuclear and gas-powered plants generated an estimated 95 percent of Germany’s electricity.
Britain has 3,500 wind turbines, but during a period of extreme cold they produced just 1.8% of UK’s electricity. But, gluttons for punishment, politicians intend building more.
When electricity demand peaked at the height of the recent heatwave in Southern Australia, the total power output from the fleet of wind farms across Victoria and South Australia was almost zero. Solar panels worked at their peak for a short time during the heat of the afternoon, but waned as the sun moved on and smokiness increased.
At dinner time on any still, cold winter night, when all suburban stoves, lights, TV’s and heaters need power, solar panels sit in the dark, powerless. And the idle wind turbines are probably drawing power from the grid for heating, lubrication, electro-magnets, hydraulics and start-up.
Despite the expenditure of trillions of dollars on conferences, green energy subsidies, research, carbon taxes, carbon trading, solar and wind subsidies, plant construction, additional transmission lines and back-up power, wind and solar only produce a derisory share of world energy (“zero” if rounded to the nearest whole number).
We keep hearing how “research” will solve the key green energy problems, but no amount of research can alter the fact that solar energy will always be variable, intermittent and dilute.
Even if solar panels collected 100% of the solar energy that fell on them, and no dust or snow ever covered the panels, the output is always variable and intermittent, with the rise and fall of the sun, the long night and the variable clouds, snow and dust.
Similarly the wind is variable, often too weak, sometimes too strong, and even when it is just right, there may be no demand for that surge of power. Germany has 23,000 wind turbines – they produce an average of about 17% of their installed capacity; on some days, they harvest nothing except subsidies (and they are good at that).
And crucially, both wind and solar energy are very dilute, so large areas of land are required to collect significant energy and to build the spider-web of roads and transmission lines required to connect to each other and to the grid. Solar panels rob green plants underneath of their sunlight. Wind turbines annoy neighbours with their noise, devalue their properties and slice up eagles, bats and migrating birds. These are very significant human and environmental costs never mentioned by green energy disciples and promoters.
No amount of research can change the key intermittent and dilute nature of green energy. We should stop wasting ever-increasing amounts of money on pointless research.
Even if we invented magic batteries (small with massive capacity, low cost, no energy losses and everlasting life), the green energy plants would still need to spend over 60% of the energy they generate to charge the batteries in order to produce 24/7 power.
There are places when green energy is appropriate and useful, and people should be free to use it at their own expense. But for grid power, it is not fit-for-purpose.
All of this explains why Green Germany is now using more coal than it did in 2009 and its power supply is more expensive and less reliable.

In a recent article, Mike Hulme argued that the debate “needs to become more political, and less scientific”. We agree, because the scientific debate has moved on from the fundamentals – there is no scientific debate about the fact that the globe is warming from human greenhouse gas emissions. So we need to hammer out political solutions rather than “debating” well-established scientific facts. – John Cook
With no rise in atmospheric temps over the past 17 years, the latest bluff in climate alarmism is that the ‘missing heat’ is hiding at the bottom of the oceans. However, the first globally accurate network of measurement buoys (3000+ ARGO satellite buoys), which descend to depths of 2,000 metres, have detected no significant increase in ocean heat since deployment in 2003.
Kevin Trenberth theorises that missing heat takes a dive into deep oceans. “The oceans can at times soak up a lot of heat. Some goes into the deep oceans where it can stay for centuries [and where lamentably, there are no reliable temperature measurements]. But heat absorbed closer to the surface can easily flow back into the air.” Yet sea surface temperatures and the upper heat content didn’t increase over the last decade by enough to account for the “missing heat” that those greenhouse gas emissions should have trapped in the Earth’s climate system but couldn’t be found. (via Forbes)
Another alarmist excuse for the 17+ year “pause” in Global Warming has been ‘scientifically’ assassinated …. by none other than the doyens of ‘Global Warming’ hysteria ~ NASA, who now admit that the “Missing (atmospheric) heat” is NOT “Hiding in the deep oceans” after all !
More from former NASA Climate Scientist Dr Roy Spencer :
NASA: The Deep Ocean Hasn’t Warmed Since 2005 (but we’re all gonna die)
October 6th, 2014 by Roy W. Spencer, Ph. D.
While still claiming that the results do not cast doubt on climate change, a new NASA press release says that the global oceans below 2,000 meters depth haven’t warmed since 2005. This is the period that we have had the deep oceans reasonably well sampled with thousands of globally-distributed Argo floats.
The thing that annoys me about such press releases is the obligatory disclaimer (no doubt crafted so that “skeptics” don’t have a field day with the press release):
“Study coauthor Josh Willis of JPL said these findings do not throw suspicion on climate change itself.”
Such statements have the usual vagueness that allows the True Believers to interpret it any way they want.
Does it mean: “It doesn’t throw suspicion on Al Gore’s impending thermogeddon”?
Or does it mean: “It doesn’t throw suspicion on the fact that climate has always changed, and always will change, with or without the help of humans”?
Or maybe something in between?
You see, as long as the IPCC gets away with basing alarmist rhetoric upon factually benign statements, like over half of the warming since the 1950s has been human induced (yawn), the global warming debate will remain dominated by extremists.
And this allows politicians to get away with saying whatever they want. Scientists are so vague that their statements can be used in a wide variety of ways that help the politician.
From the well-established scientific fact that there has been no global warming, at all, for the past 17 years, it’s not hard to see why Cook and the global warming climate change cult believe the debate “needs to become more political, and less scientific”.
Seventeen and a half years. Not a flicker of global warming. The RSS satellite record, the first of the five global-temperature datasets to report its February value, shows a zero trend for an impressive 210 months. Miss Brevis, send a postcard to Mr Gore:
Make that 18 years and 4 months, or now a “pause” of global warming lasting for more than half the entire satellite record:
