Allowing us more time to act is a weasel-worded phrase to keep from stating the obvious conclusion if the absence of Sunspots and a subsequent drop in temp coincide.
>> It might even be the case that the Earth’s response to low solar activity ...
Imagine that, an adaptive ecosystem.
FROM NASA:
March 6, 2006:
February 2006 was the first month in almost ten years with mostly no sunspots. For 21 of February’s 28 days, the sun was blank. Hathaway expects this situation to continue for the rest of 2006.

Obviously something affecting climate is more powerful than any projections of AGW. Scientists have only guesses about the causes of the Ice Age cycles. Without understanding those, then they don’t understand the climate.

This prediction was probably based on the expectation that Solar Cycle 25 would be the first major weak one. Not Solar Cycle 24, which is now developing as a weak one. So the estimate of a 1.5C drop by 2020, will probably now occur much sooner then expected.

After a period of very high solar activity (high numbers of sunspots) in the 20th century, our sun has suddenly gone exceptionally quiet, according to astronomer Dr. David Whitehouse.
We are currently at the end of one cycle of activity and astronomers keep waiting for the sunspots to return and mark the start of the next cycle 24, but so far there has been no sign of that returning anytime soon.
