In face of intense criticism from alarmist scientists, Dr. John Christy went to great lengths in a Tuesday congressional hearing to detail why satellite-derived temperatures are much more reliable indicators of warming than surface thermometers.
“That’s where the real mass of the climate system exists in terms of the atmosphere,” Christy, a climate scientist at the University of Alabama and Alabama’s state climatologist, said in a Wednesday hearing before the House science committee.
“When a theory contradicts the facts” you need to change the theory, Christy said. “The real world is not going along with rapid warming. The models need to go back to the drawing board.”
Texas Republican Rep. Lamar Smith, the committee’s chairman, convened a hearing on the implications of President Barack Obama’s recent United Nations deal in Paris, which agreed to cut carbon dioxide emissions.
Christy doesn’t think signing onto a U.N. deal is good for Americans, and challenges the very data politicians and environmentalists rely on to push green energy policies.
“One of my many climate interests is the way surface temperatures are measured and how surface temperatures, especially over land, are affected by their surroundings,” Christy wrote in his prepared testimony.
Christy recently co-authored a study with veteran meteorologist Anthony Watts that found the National Oceanic and Atmospheric Administration (NOAA) was basing its temperature adjustments on “compromised” temperature data.
The study found most of NOAA’s 1,218 thermometers were sited near artificial surfaces and heat sources like concrete, asphalt, and air conditioner exhausts that were causing more warming to show in the U.S. temperature record than was present at weather stations that were well-sited.
Christy and Watts surmised NOAA was basing its temperature adjustments (efforts made to get “biases” out of the temperature record) on bad data.
“I closely examined individual stations in different regions and have come to the conclusion that the magnitude of the relatively small signal we seek in human-induced climate change is easily convoluted by the growth of infrastructure around the thermometer stations and the variety of changes these stations undergo through time, as well as the variability of the natural ups and downs of climate,” Christy noted in his testimony.
“It is difficult to adjust for these contaminating factors to extract a pure dataset for greenhouse detection because often the non-climatic influence comes along very gradually just as is expected of the response to the enhanced greenhouse effect,” Christy added.
But that’s why Christy argues satellite-derived temperatures are a better way to look at how greenhouse gases are impacting the Earth’s climate.
“The bulk atmospheric temperature is where the signal is the largest,” Christy said in the hearing, referring to the greenhouse gas effect. “We have measurements for that — it doesn’t match up with the models.”
Satellite-derived temperatures have come under fire recently by scientists more alarmist about global warming than Christy, but the Alabama climatologist addressed those criticisms.
“Because this result challenges the current theory of greenhouse warming in relatively straightforward fashion, there have been several well-funded attacks on those of us who build and use such datasets and on the datasets themselves,” Christy said.
Climate models for the bulk atmosphere (where satellites measure temperature) show 2.5 times as much warming as has been observed by satellites and weather balloons.
“It is a bold strategy in my view to actively promote the output of theoretical climate models while attacking the multiple lines of evidence from observations,” Christy wrote. “Note that none of the observational datasets are perfect and continued scrutiny is healthy, but when multiple, independent groups generate the datasets and then when the results for two completely independent systems (balloons and satellites) agree closely with each other and disagree with the model output, one is left scratching one’s head at the decision to launch an offensive against the data.”
Any third grader could debunk the flawed land surface data. I did exactly that right in my own town.
As far as satellite derived temp data goes, it seems to me that sticking with ground based temps is better because that’s where the people, animals, plants and ice exist. Atmospheric temps can mask surface temps due to inversion layers, jet streams, high & low pressure systems, smoke, dust and ash in the atmosphere, cloud cover and who knows what else.
Take the potential for making money out of the climate change agenda and watch how fast globull warming fades into the sunset.
Great last line, IS.
This is 2 hours long – I watched it. The pro Globull Warmists didn’t mention anything about the science to support their flimsy case. They just droned on about how many countries signed onto the non-binding Paris deal which is based on countries ‘promising’ to reduce emissions while collecting the $100 Billion dollars. They also droned on how many corporations supported their political goals – of course they do, our oligarchy is an incestuous relationship between Gov’t and Big Corporations.
I have noticed there is less global warming at night. And in the shade. The more .gov talks about global warming, the more I expect an ice age.
55 degrees here in Boston this morning at 6:00 AM. If global warming is the cause I say bring it on. I’m happy to have no snow to shovel.
Bob.
The Climate stuff is a political movement not a scientific one.
Bostonbob, you are a fucking moron. You know what happens this year? Lots of fruit losses because the trees get tricked into thinking it’s spring. The daffodils that bloomed in VA last month aren’t going to bloom again in April.
You’re all so egocentric and smug, you don’t give a thought that other creatures, INCLUDING OnES YOU NEED TO SuRVIVE, are just not designed to live well at temps 40 degrees higher than normal: trees, fish, food crops.
This obsession with politics over facts is some kind of mental illness y’all have. Look out the goddam window, freaks!
Looks like Chubby Bubbles doesn’t like warm weather. Did you like the fucking blizzard last week asshole?
You enviro-nazis have pea brains incapable of using reason or facts. Feelings and emotions drive you douchebags.
I guess you are the perfect example of what government run public education can do to the brains of kids. Your mush mouth drivel about fucking daffodils is pathetic.
Let me guess. You’re a fry cook at McDonalds with a $60,000 student loan balance for your degree in global warming studies.
The stupid – it burns.
Chubby Bubbles….ever hear of an El Nino? You know that naturally occurring event – why don’t you look it up and learn (something you haven’t done so far in your life).
Weather has become big business even in the last 10 years. It has been folded into the overall larger bullshit industry. I knew this was going to happen about 10 years ago when NBC bought The Weather Channel.
Now, even in the past 2-3 years the weather websites have been compromised. The one I used to go to because it was the most “just the facts, ma’am” now peddles man-made climate change drivel at every turn, names snowstorms like they are pets, and has a shit-flinging monkey comment section on every article. They actually posted this bullshit yesterday, I shit you not:
“The Groundhog Oscillation: convincing evidence of climate change!
According to a 2001 article published in the prestigious Annals of Improbable Research, “The Groundhog Oscillation: Evidence of Global Change”, Punxsutawney Phil’s forecasts have shown a high variability since 1980. This pattern, part of the larger “Groundhog Oscillation” or GO cycle, is convincing evidence of human-caused climate change.”
Yep, they are using a 15 year old article in some bullshit no one has ever heard of based on a fucking GROUNDHOG to push climate change. Not even that, it is based on some octogenarian’s interpretation of a groundhog’s reaction to sunlight. Today they are whining about shrinking sea ice, presumably because we haven’t had a good Titanic disaster in 100 years. Their core audience eats this shit up though. How do they do it? They simply ignore everything that doesn’t fit the agenda, and cry wolf about everything that does. So if the sea ice was having a splendid year you would not hear a peep about it. But if it shrinks next year they will be all up in arms.
From now on I will use this site: https://thefuckingweather.com/
And I’m sure if you peek under the covers you’ll find these so-called “scientists” (do they practice science in Alabama?) are funded by oil companies or their minions. Don’t be misled.
How come the official science does admit that for multi millions of years, this worshipped blue/green oh so perishable planet has suffered (cold) multiple ice age glaciations, one being described as “snowball’ Earth, followed by successive warm periods, so that large portions of the planet were at times covered with areas of an ice sheet up to two miles thick, and it all happened in a fashion of natural occurrence?? Repeatedly.
In 2012, it was discovered that Antarctica 50 M years ago had an average type temp of 70 F. That was supported by evidence in drill holes.
And 20 T. years ago, the last massive ice sheet extended into northern USA. And it melted. Cycles of warm and cold, forever.
Oh, but I forgot, the climate sien tics tell us it was all due to changes in CO2 levels. AH HA! I knew it!. But what they do never talk about is that there is another older theory, more to me logical. The cycles depend on variations in orbit and inclination. But, so far, there is no way to change orbit and inclination. So, no way to make money that way. Or get a free plane ride and hotel room to the next climate festival.
Anyway, I think the ratio of CO2 to other atmosphere gases is 1:2499. Pour yourself a drink . 2499 cc water. I cc whiskey. Do you get plastered?? I just don’t get it. CO2 is .04%. I think that works out to that ratio. Corrections welcome.
Please all ya’ll government doubters, get a grip! NASA Scientist are just as credible as Congress, the BLS Economist, the IRS, DoJ, Homeland Security, the MSM, Hollywood, Monsanto, North Korea etc. Are you going to believe your lying eyes when you think you see Chemtrails or the highly paid venerable government Scientist?
Christy, a climate scientist at the University of Alabama and Alabama’s state climatologist
serious? you consider the comments of an ignoramus from one of the two most ignorant states in the country, populated 95% by utter total and complete shit-for-brains with zero capacity to form a grammatically correct sentence to be something worth discussing? you know why he’s the state climatologist of alabama? because he’s one of the four people in the entire state who can spell his own fucking name… and naturally, ignoramuses like you ridiculous shitforbrains asshats eat it all up… cuz you’re too goddam stupid to know the difference… you wouldn’t understand even the simplest science if it crawled out of your fat-assed mommy’s repugnant cunt and slapped you on the head with a textbook…
