(CNSNews.com) – Sen. Ted Cruz (R-TX) pointed out Tuesday that Secretary of State John Kerry - who is currently in Paris calling for a climate change agreement with a “legally binding” enforcement mechanism - was “wildly, extraordinarily, entirely wrong” when as a senator in 2009, Kerry predicted that the Arctic would be “ice free in the summer of 2013”.
“The summer of 2013 has come and gone, and John Kerry was not just a little bit, he was wildly, extraordinarily, entirely wrong,” Cruz said Tuesday in his opening statement at a hearing of the Senate Science Subcommittee he chairs.
“Here are the inconvenient facts about the polar ice caps. The Arctic is not ice free. This year’s minimum sea ice extent was well above the record low observed in 2011," Cruz said..
“In the Antarctic, a recent study from the journal Glaciology indicates that the ice is not only not decreasing, but is in fact increasing in mass, directly contrary to what the global warming alarmists had told us would be happening.
"This is not what their climate models projected,” Cruz said.
”According to the satellite data, there has been no significant global warming for the past 18 years," Cruz continued."Those are the data. The global warming alarmists don’t like these data. They are inconvenient to their narrative. But facts and evidence matters.”
John Christy, director of the Earth System Science Center at the University of Alabama in Huntsville who tracks temperature data gathered by satellites and weather balloons worldwide, told the subcommittee that “there is clear evidence that the [computer climate] models have a strong tendency to over-warm the atmosphere, relative to actual observations.
"These models failed at the simple test of telling us ‘what’ has already happened, and thus would not be in a position to give us a confident answer to ‘what’ may happen in the future and ‘why'. As such, they would be of highly questionable value in determining policy that should depend on a very confident understanding of how the climate system works,” Christy testified.
Another climate scientist, Judith Curry of the Georgia Institute of Technology, agreed that “the growing discrepancy between climate model predictions and the observations has raised serious questions about the climate models that are being used as the basis for national and international energy and climate policies."
But Admiral David Titley, founding director of the Center for Solutions to Weather and Climate Risk at Penn State, testified that “recent measured changes in climate include a multi-decade increase in the year-round, global-average air temperature near Earth’s surface.”
“In consequence of the temperature increase, glaciers are melting, the Greenland and Antarctic ice sheets are losing mass, and sea level is rising," he stated, adding that "human influences.... have far outweighed the natural forcings [of greenhouse gases}, as well as internal variability of the climate system."
Titley also claimed that the 18-year "pause" in global warming was due to data manipulation, and that it does not change the "longer-term upward trend".
"I would be remiss if I did not address the so-called 'pause' in global surface temperatures," he told the subcommittee.
"It is easy to find arbitrary 5-15 year periods when, with careful choosing of the start and stop dates, one can claim there has been no change in global temperatures. This method of analysis does not account for the longer-term upward tend that presists through the relatively shor-term variations," he said.
