Antarctica hasn’t warmed as much over the last century as climate models had originally predicted, a new study finds.
Climate change’s effects on Antarctica are of particular interest because of the substantial amount of water locked up in its ice sheets. Should that water begin to melt, sea levels around the globe could rise and inundate low-lying coastal areas.
The new study, detailed in the April 5 issue of the journal Geophysical Research Letters, marks the first time that researchers have been able to give a progress report on Antarctic climate model projections by comparing climate records to model simulations (these comparisons have been done for the other six continents). Information about Antarctica’s harsh weather patterns has traditionally been limited, but temperature records from ice cores and ground weather stations have recently been constructed, giving scientists the missing information they needed.
“This is a really important exercise for these climate models,” said study leader Andrew Monaghan of the National Center for Atmospheric Research in Boulder, Co.
Monaghan and his team found that while climate models projected temperature increases of 1.4 degrees Fahrenheit (0.75 degrees Celsius) over the past century, temperatures were observed to have risen by only 0.4 F (0.2 C).
“This is showing us that, over the past century, most of Antarctica has not undergone the fairly dramatic warming that has affected the rest of the globe,” Monaghan said.
The gap between prediction and reality seemed to be caused by the models overestimating the amount of water vapor in the Antarctic atmosphere.
Wow! Another case of the computer models being wrongo….shocking!
Howard Hayden describes the computer models as such:
Howard Hayden, physics professor emeritus at the University of Connecticut, has described the machinery of the computer models used by the IPCC and others to predict imminent and cataclysmic climate change as ones that take “garbage in” and spit “gospel out.”
In a study published last August in the journal Science, U.K. researchers said:
“A common criticism of global climate models . . . has been that they only include factors such as solar radiation, atmospheric aerosols and greenhouse gases, which are affected by changes outside the climate system (while neglecting) internal climate change variability that arises from natural changes from within the system, like El Nino, fluctuations in ocean circulation and anomalies in ocean heat content.”
Listen. There is NO consensus on man-made global warming, you can even check here for a list of 2660 Physicists, Geophysicists, Climatologists, Meteorologists, Oceanographers, and Evironmental Scientists who don’t believe the hype. For those who insist the debate is over, that man is causing global warming, this quote from George Will Should be stamped on their foreheads:
“People only insist that a debate stop when they are afraid of what might be learned if it continues.”
Its all about keeping the funding rolling that allows them to enjoy the lifestyle they so enjoy in the here and now. So keep it coming with these computer models that predict the sky to fall and the waters to boil. Each one that gets proven wrong just makes me smile.
