Climate Change: About that big yellow thing that hangs in the sky each day …
If the findings of a new study are correct, it appears the sun is indeed the primary reason for global temps being higher for a few years. I know, you’re shocked aren’t you? Who would have thought the big heater in the sky could have a role in temperature increases? Well not the alarmists.
As illustrated in the figure below, the authors report there is “remarkable agreement” among the overlapping years of their reconstruction (solid black line) and the number of sunspots recorded from direct observations since 1610 (red line). Their reconstruction of solar activity also displays several “distinct features,” including several “well-defined Grand minima of solar activity, ca. 770 BC, 350 BC, 680 AD, 1050 AD, 1310 AD, 1470 AD, and 1680 AD,” as well as “the modern Grand maximum (which occurred during solar cycles 19-23, i.e., 1950-2009),” which they describe as “a rare or even unique event, in both magnitude and duration, in the past three millennia.”
Figure 1. Reconstructed decadal average of sunspot numbers for the period 1150 BC-1950 AD (black line). The 95% confidence interval is shown by the gray shading and directly measured sunspot numbers are shown in red. The horizontal dashed lines demark the bounds of the three suggested modes (Grand Minimum, Regular, and Grand Maximum) as defined by Usoskin et al.
A “rare or even unique event” which had zip to do with man or CO2, but certainly coincided with the panic about man-made global warming, huh? And the alarmists gave what sort of influence to the sun in their models?
Usoskin et al. (2014) write their results “provide important constraints for both dynamo models of Sun-like stars and investigations of possible solar influence on Earth’s climate.” They also illustrate the importance of improving the quality of such reconstructions, in light of the fact that previous reconstructions of this nature “did not reveal any clear signature of distinct modes” in solar activity.
Unfortunately, it was beyond the scope of this paper to address the potential impact of solar activity on climate. Yet the reconstruction leaves a very big question unanswered — What effect did the Grand maximum of solar activity that occurred between 1950 and 2009 have on Earth’s climate? As a “unique” and “rare” event in terms of both magnitude and duration, one would think a lot more time and effort would be spent by the IPCC and others in answering that question. Instead, IPCC scientists have conducted relatively few studies of the Sun’s influence on modern warming, assuming that the temperature influence of this rare and unique Grand maximum of solar activity, which has occurred only once in the past 3,000 years, is far inferior to the radiative power provided by the rising CO2 concentration of the Earth’s atmosphere.
Not that any of these facts will at all derail the Alarmist’s rush to provide an expensive solution to a non-existent problem. Doug Hoffman summarizes what we who are totally skeptical of the “science” of man-made global warming face:
One of the sad side effects of the global warming climate scam is the way otherwise fairly intelligent people have been snookered into believing the dumbest things. There is no shortage of “experts” who gleefully back up claims of climate induced catastrophe—some with scholarly gravitas, others with fanatical shrillness. And the list of false and debunked claims goes on and on. Part of the blame for all these faux catastrophes rests squarely on the news media. Operating under the old adage, “if it bleeds it leads,” the mindless vultures of the world’s news agencies flock to report any calamity, more than happy to attributed the event to climate change. Instead of registering guns, governments should register cameras and microphones—they are truly dangerous weapons in the hands of the breathtakingly ignorant members of the fourth estate.
Indeed. One of the things we’ve discussed here before is how the rise of advocacy “journalism” harms us all. This “scam”, as Hoffman characterizes it, points out in spades how poorly we’re served by our media today.
Don’t expect this study to get much attention. It is counter to the conventional wisdom, counter to the desire to further empower government and certainly counter to the desire by those in power to cash in on this faux crisis.
