the political schmucks running agw crowd are NOT dumb.
they KNOW we are near the end of this warming cycle, and that's EXACTLY why they are pushing so dang FURIOUSLY HARD to get agw taxes and regulations in place ASAP ASAP ASAP - because in a few years it will be cooling --- they want to hamper capitalism/free markets / industrialization/globalization --- it's always been the left's long term goal - and they KNOW that it's NOW OR NEVER!
And now the rest of the story:
NASA says the solar conveyor has slowed. The solar conveyor speed predicts the sunspot level two cycles in advance, about 20 years.
"Normally, the conveyor belt moves about 1 meter per second—walking pace," says Hathaway. "That's how it has been since the late 19th century." In recent years, however, the belt has decelerated to 0.75 m/s in the north and 0.35 m/s in the south. "We've never seen speeds so low."What does all this have to do with the climate on earth? Let us look at the climate when sunspot levels were low:
According to theory and observation, the speed of the belt foretells the intensity of sunspot activity ~20 years in the future. A slow belt means lower solar activity; a fast belt means stronger activity. The reasons for this are explained in the Science@NASA story Solar Storm Warning.
"The slowdown we see now means that Solar Cycle 25, peaking around the year 2022, could be one of the weakest in centuries," says Hathaway.
...the Sporer, Maunder, and Dalton minima coincide with the colder periods of the Little Ice Age, which lasted from about 1450 to 1820. More recently it was discovered that the sunspot number during 1861-1989 shows a remarkable parallelism with the simultaneous variation in northern hemisphere mean temperatures (2). There is an even better correlation with the length of the solar cycle, between years of the highest numbers of sunspots. For example, the temperature anomaly was - 0.4 K in 1890 when the cycle was 11.7 years, but + 0.25 K in 1989 when the cycle was 9.8 years. Some critics of the theory of man-induced global warming have seized on this discovery to criticize the greenhouse gas theory.If sunspots are going to decline in the near future the global warming era may be over. Especially if the sun's effect on Clouds turns out to be affected by solar activity as some scientists have experimentally proved.
All this evokes the important question of how sunspots affect the Earth's climate. To answer this question, we need to know how total solar irradiance received by the Earth is affected by sunspot activity.
Intuitively one may assume the that total solar irradiance would decrease as the number of (optically dark) sunspots increased. However direct satellite measurements of irradiance have shown just the opposite to be the case. This means that more sunspots deliver more energy to the atmosphere, so that global temperatures should rise.
So are things warming up now?
1. Since about 2002 there has been NO statistically significant global average warming in the lower and middle troposphere,Well what do you know? In addition global temperatures have been on the decline for the last few years. We had a spike in 2004 I believe, but otherwise temperatures have been declining since about 2000 or so.
2. Since about 1995 there has been NO statistically significant cooling in the stratosphere.
The IPCC SPM conclusion that “warming of the climate system is unequivocal” is wrong as it ignores the lack of such warming in recent years by these other metrics of climate system heat changes...
