In an earlier posting, the case for CO2 controlling global temperature change was discussed. Several cases were examined that suggest that CO2 probably is a minor factor. Yes, I do have a bias that the Sun is most likely the main driver of global climate. But I believe that bias is well founded.
As I began to prepare a posting on this topic, on 10 June a new posting on WattsUpWithThat by Mike Jonas appeared. It covers, most of what I had planned to say. He says it very well, albeit in a lot of words. His Figure 7, “Correlation of sunspot cycle length with temperature” is thought by some to have been disproven, so you may want to tread lightly on that. I also think that he should have used an article from December 2016 CERN publication that strengthened his case for the Svensmark theory of galactic cosmic rays/cloud formation/cooling. See my comment on that by clicking here.
My thoughts on this topic would be less informative than those by Mike Jonas. Thus I am reblogging his posting:
Indirect Effects of the Sun on Earth’s Climate
By Mike Jonas 10 June 2017
For a long time, I have been bitterly disappointed at the blinkered lopsided attitude of the IPCC and of many climate scientists, by which they readily accepted spurious indirect effects from CO2-driven global warming (the “feedbacks”), yet found a range of excuses for ignoring the possibility that there might be any indirect effects from the sun. For example, in AR4 2.7.1 they say “empirical results since the TAR have strengthened the evidence for solar forcing of climate change” but there is nothing in the models for this, because there is “ongoing debate“, or it “remains ambiguous“, etc, etc.
In this article, I explore the scientific literature on possible solar indirect effects on climate, and suggest a reasonable way of looking at them. This should also answer Leif Svalgaard’s question, though it seems rather unlikely that he would be unaware of any of the material cited here. Certainly just about everything in this article has already appeared on WUWT; the aim here is to present it in a single article (sorry it’s so long). I provide some links to the works of people like Jasper Kirkby, Nir Shaviv and Nigel Calder. For those who have time, those works are worth reading in their entirety.

Back when there was temporary shortage of natural gas, that fossil fuel was the favorite of warmers. When it became abundant, they were against it. They just pretend to be even handed. Well what about nuclear energy? It doesn’t produce carbon dioxide (CO2) but they do not like it. My guess is that many of them are just following through on their objective of destroying capitalism.
However, a group of influential warmers now say they were wrong to oppose nuclear energy.
At the Paris COP21 in December 2015, a press conference was held where 4 noted warmers announced that they were going to back development of nuclear energy.

How Cycle 24 June Sunspot plot will look when the new Sunspot numbering system is used is not yet clear. Using the “old Wolf system” that is the International Smoothed Sunspot number basis, it would be expressed as 57.2 thirty day average versus last months number of 58.8. The number for June 2015 is estimated to be 46.9 when the smoothing process is employed. What ever the measuring system, Cycle 24 is still heading downward to a minimum.
VOX.com has a page with “40 maps that explain the universe”. Photos and drawing plus text are there for your review. Some of the illustrations are really eye catching. For example:
Even a single comet is pretty darn big
This is the comet 67P/C-G — which the Philae probe landed on in November 2014 — superimposed on Los Angeles. In terms of space, the comet is absolutely tiny: just 3.5 miles wide.
Solar Cycle 24 activity, using Sunspots as the proxy, is slowing down considerably. The International number for March was 38.4. The smoothed International Sunspot number is estimated at 56.1. The March number will not be official for another 6 months. The chart below, the black line, labeled Ri is the International number which is the sum of the Rnorth (red) and Rsouth (green) Sunspot numbers.
Climate cycles are continuously happening on Earth since its beginning estimated to be some 4.5 billion years ago. Detailing the earliest climate cycles can only be done by painting with the broadest of brushes. In more recent times, proxies, such as ice cores and oxygen isotope measurements are available for use in reconstructing these cycles. The globe has experienced glaciers in relatively recent times and in the not too distant future will surely experience glaciers again. The profound changes that take place resulting in glacial periods are of great interest.

The Mars Rover Curiosity drilled in the John Klein area of Mars, (about 500 meters East of where it landed) and the sedimentary rock samples were passed to the on-board analyzers. The objective was to determine if the minerals necessary to maintain life were in this sample. Carbon, oxygen and sulfur in various forms were found. The NASA team has concluded that the John Klein area was once a fresh water environment that would have been favorable to organic life. Other Rovers samplings have found areas that once contained water but the conditions were not considered suitable to support organic life. On March 15 2013, the NASA team provided an informative video “Curiosity Rover Hits Paydirt”. It can be seen by clicking on the link below:
