Scientists Tout New Study On Man-Made Warming As Americans Sit Under Record Snowfall

He's back!Michael Mann: He’s back!The climate scientist at the center of the Climategate email scandal is out with a new study claiming man-made warming is responsible for record-breaking warmth in recent years.

The study’s timing, however, couldn’t have been any worse — a major blizzard has millions of Americans sitting under record levels of snowfall.

Climate scientists Michael Mann of Penn State University, along with other scientists, published a new study Monday claiming “record-setting temperatures were extremely unlikely to have occurred in the absence of human-caused climate change.”

But Mann’s study comes after Winter Storm Jonas ripped through the Eastern Seaboard, causing traffic jams, power outages and reportedly 30 fatalities. In the end, Americans from North Carolina to New York City were covered in 2 feet of snow.

AccuWeather reports that Washington, D.C., Baltimore, New York City and Philadelphia “shattered daily records for the most snow on Jan. 23.” No doubt, millions of people spent Sunday shoveling their driveways and digging out their cars.

While activists have tried to link the blizzard to global warming, many scientists have chosen to focus on surface temperature data showing a string of record-breaking years over the last decade. They claim this is due to man-made carbon dioxide emissions in the atmosphere.

“These same record temperatures were, by contrast, quite likely to have occurred in the presence of anthropogenic climate forcing,” Mann and his co-authors wrote, adding that nature and the sun had little to do with the Earth being so warm in the last decade or so.

But many of these record years took place during the so-called “hiatus” of global warming — a period of 15 years or so with no significant global warming. That’s because while temperatures remain constant every year will be near or at record levels, but only by a tiny margin.

For example, 2014 was declared the warmest year on record by the National Aeronautics and Space Administration and the National Oceanic and Atmospheric Administration, but they were only between 38 percent and 48 percent sure this was correct.

“With 2014 essentially tied with 2005 and 2010 for hottest year, this implies that there has been essentially no trend in warming over the past decade,” Judith Curry, a climate scientist at the Georgia Institute of Technology said of government scientists’ announcement last year.

“This ‘almost’ record year does not help the growing discrepancy between the climate model projections and the surface temperature observations,” Curry said.

    Gee what a revelation …humans have an impact on the climate . A number of scientists concluded that ? Who knew ?

    Did you know that if you put a pin in a balloon air comes out ? The same thing happens to the oh my God the earth has fever scam .

    I am waiting for Michael Mann and his fellow clutch of modellers to explain why climate models so consistently and significantly overstate warming .

    Climate changes ….good . Warming happens ….good . Is there anyone that would like to see a cooling trend to return us to the last ice age ?

    The “warming ” is so minuscule as to be statistical noise swamped by the big dogs in the room …natural variability .

    We have numerous environmental challenges (like getting the EPA staff to quit polluting rivers ) so why spend $$trillions on essentially a non issue ? Oh I think I answered my own question $$$.

    In bygone days, kings would employ jesters who were free to say anything they liked to the king; it was the king’s way of not losing touch with reality.

    Obama could use a jester.

    Biden partially fits the role, but

    in idiotic appearance only.

    I though Kerry might qualify but after seeing
    the slick comedic lines of the Democrat Hank Johnson , who expressed his concerned about Guam island flipping over due to added military people stationed there , I would say Kerry was just voted off the island .

    The problem with this study is three-fold.

    First, their junk science says that the tropical upper troposphere must be warming faster than Earth’s surface. However, this hotspot simply does not exist, has not been detected after millions of readings; in fact, this region of the atmosphere has been mildly cooling for thirty years.

    Second, they want us to believe that the upper troposphere at -17 deg C warms the surface at 15 deg C. However, this is completely impossible and goes against much more powerful science called THERMODYNAMICS. A cold body cannot warm a hot body; otherwise the walls of a room would cook those in it.

    Third, no gas at any concentration in the atmosphere can detectably warm the atmosphere. The key is that the atmosphere has convection that carries, along with water evaporation, carries 85% of the energy budget from Earth’s surface to altitude where adiabatic cooling and condensation releases energy that is lost to space. Only in a real greenhouse is convection suppressed and the trapped air warmed.

    The above paper is junk science and denies very basic laws of thermodynamics.

    “claiming “record-setting temperatures were extremely unlikely to have occurred in the absence of human-caused climate change.””

    Putting aside that the real data do not show “record-setting temperatures”—only the dishonestly altered data shows warming—they pointedly ignore all solar influences, all ocean cycles, and over 50 other major factors that influence Earth’s climate.

    Some similar junk-scientists reported today that we have not detected any alien civilizations because they most likely die from warming or cooling due to their gas emissions. A TRACE GAS DOES RUN OUR PLANET or anybody else’s! CO2 IS PLANT FOOD and CO2 and methane have a five-year half-life in the atmosphere.

    For the above “scientists” to claim any warming is most likely due to human activities is to ignore the Holocene Optimum, Egyptian Warm Period (WP), Minoan WP, Roman WP, Medieval WP and Modern WP, each succeeding warm peak being lower than the last, showing a clear downward trend. As we are seeing what appears to be the longest Interglacial of the last four cycles over 400.000 years, we are most likely due to drop off the edge into the next glacial.

    It is hubris to even pretend that humans control the climate. It bespeaks the arrogance and the willful ignorance of these junk scientists, peddling an agenda’s propaganda not science.

    herr mann
    if he would shut up
    and disappear
    he wouldn’t
    be ridiculed
