A new satellite predicts at least 23 years of global cooling

Several Canadian environmental scientists agree that the new Jason satellite indicates at least a 23-year cycle of global cooling ahead.

This oceanographic satellite shows a much larger than normal persistent Pacific Decadal Oscillation (PDO). Cooler PDO phases usually last 21 to 25 years, so we should be quite chilly as a planet until at least 2030, maybe longer.

A point about natural cycles:

These alternating natural climatic cycles defy the so-called “climate consensus” that human-emitted carbon dioxide was responsible totally for the recent cycle of global warming that began in the late 1970s and peaked in 1998.

The Earth’s previous warming phase from 1915 through 1939, which peaked in 1936 during the infamous Dust Bowl Days, was almost as warm as the recent cycle of global warming.

[…]

The last cooler cycle of global temperatures occurred from late 1939 to early 1976, peaking (or bottoming) in 1973. The harsh winters during World War II helped the U.S. and its allies defeat the Germans and later assisted our G.I.s in the Korean War due to extremely heavy snows and subzero temperatures north of the 38th Parallel.

In the past 10 years, especially the past couple of years, the Earth’s climate has begun to cool, even though CO2 emissions have soared on a worldwide scale.

Should we indeed cool down as it seems the case, the case of cyclic climate change driven by natural causes should hold sway over any “consensus science” aimed at claiming a warming cycle has been begun by man and is unstoppable.

Another scientist speaking out against the “scientific consensus” is professor Tim Patterson:

A professor from Carleton University may get the cold shoulder from environmentalists when he speaks in London tomorrow.

Tim Patterson, a paleoclimatologist from the department of Earth sciences, will give an opposing view to Al Gore’s An Inconvenient Truth. Patterson is speaking at a Canadian Club of London luncheon.

He believes we should expect global cooling rather than global warming in the coming years.

“We’re off on the wrong foot,” he says. “There’s been no global warming in the 21st century.”

Climate change is not caused by humans, but by natural forces, Patterson says.

His research indicates cosmic rays from the sun affect temperature by impacting cloud formation.

When there are fewer cosmic rays, there are fewer clouds. Fewer clouds lead to warmer temperatures.

Cloud albedo has much to do with the regulation of temperature on the earth and is something which is poorly modeled or not modeled at all within the climate models used to drive the AGW theory. It is one of the reasons that AGW is now coming under increased scientific scrutiny and all but destroyed the former ‘consensus’.

Bottom line – the only constant is climate change and it is beginning to appear that it is both natural and cyclic and pretty much driven by the sun. What a surprise.
