Now it’s not just the sunspots that predict a 23-year global cooling. The new Jason oceanographic satellite shows that 2007 was a “cool” La Nina year—but Jason also says something more important is at work: The much larger and more persistent Pacific Decadal Oscillation (PDO) has turned into its cool phase, telling us to expect moderately lower global temperatures until 2030 or so.
For the past century at least, global temperatures have tended to mirror the 20-to 30-year warmings and coolings of the north-central Pacific Ocean. We don’t know just why, but the pattern of the last century is clear: the earth warmed from about 1915 to1940, while the PDO was also warming (1925 to 46). The earth cooled from 1940 to 1975, while the PDO was cooling (1946 to 1977). The strong global warming from 1976 to 1998 was accompanied by a strong and almost-constant warming of the north-central Pacific. Ancient tree rings in Baja California and Mexico show there have been 11 such PDO shifts since 1650, averaging 23 years on length.
…All of this defies the “consensus” that human-emitted carbon dioxide has been responsible for our global warming. But the evidence for man-made warming has never been as strong as its Green advocates maintained. The earth’s warming from 1915 to 1940 was just about as strong as the “scary” 1975 to 1998 warming in both scope and duration—and occurred too early to be blamed on human-emitted CO2. The cooling from 1940 to 1975 defied the Greenhouse Theory, occurring during the first big surge of man-made greenhouse emissions. Most recently, the climate has stubbornly refused to warm since 1998, even though human CO2 emissions have continued to rise strongly.
The Jason satellite is an updated and more-accurate version of the Poseidon satellite that has been monitoring the oceans since 1992, picking up ocean wind speeds, wave heights, and sea level changes. Jason is run by NASA’s Jet Propulsion Laboratory and a French team.
How many years of declining world temperature would it take now—in the wake of the ten-year non-warming since 1998—to break up Al Gore’s “climate change consensus”?
Australian Researchers Warn of Global Cooling
“Spin-orbit coupling” to blame; effects could last decades.
July 1, 2008
A new paper published by the Astronomical Society of Australia is warning of upcoming global cooling due to lessened solar activity. The study, written by three Australian researchers, has identified what is known as a “spin-orbit coupling” affecting the rotation rate of the sun. That rotation, in turn, is linked to the intensity of the solar cycle and climate changes here on Earth.
The study’s lead author, Ian Wilson, explains further, “[The paper] supports the contention that the level of activity on the Sun will significantly diminish sometime in the next decade and remain low for about 20 – 30 years.”
According to Wilson, the result is a strong, rapid pulse of global cooling, “On each occasion that the Sun has done this in the past the World’s mean temperature has dropped by ~ 1 – 2 C.”
A 2 C drop would be twice as large as all the warming the earth has experienced since the start of the industrial era, and would be significant enough to impact global agriculture output.
Earlier this year, astronomers from around the world noted solar activity was suspiciously low; some began predicting global cooling at that time. Since then, activity has remained far below average, with it now being over two months since a single sunspot has appeared on the surface of the sun.
In May, a team of German climatologists published research stating that, due to “natural effects”, global warming would halt for up to 15 years.
