I have noticed that the long days in the mid-summer when the sun shines for a lot more hours out of the 24 are usually a lot warmer than the short days in mid-winter when we have far fewer hours of sun but I thought it was just that people drive more in summer so all that exhaust gas holds the heat in. One thing that I HAVE finally figured out is that the Moon is more important than the Sun because the Moon shines at night when we really need light and the Sun only shines in the daytime when there is plenty of light anyway.

Now I have to try to understand that other side of the equator thing you mentioned, is there a school where I can study that? I think I may have a tough time with it.

You know, I never thought about that moon thing before, but... by golly... you’re right!

This causes a redistribution of heat – so while Europe and the US may be cooler, Canada and the Mediterranean will be warmer, and there is little direct impact on global temperatures

You can lead a climate changer to tea, but you cannot make them drink. There is no such think as a global temperature. All temperatures are local approximations for the heat content of the atmosphere. Therefore, you know nothing by studying and analyzing global temperatures. After drinking that tea, ye shall be free.

Colder in some places. Lack of solar activity, specifically ultraviolet leads to cooling of portions of the stratosphere. The stratosphere also responds to weather in the troposphere, a stronger influence. Somewhere in the interaction between the troposphere and stratosphere we get more blocking and more storms, cold outbreaks, etc. The low solar does not cool the earth as a whole (not low enough, doesn’t affect the troposphere much, etc) But what could happen is that the increased blocking and storms cool the earth as a whole.

While it is true that”global average temperature” does not exist, there are ways to average a lot of temperatures (especially measured by satellite) and get an indication of an average. When they do that (e.g. UAH) they see a whole lot of fluctuation day-to-day and week-to-week mainly from earthly weather but also from solar fluctuations.

Well, hell there’s no money to be made in this.

[justa-hairyape]

Temperature is the wrong metric. Just a lot of noise. We should have been measuring heat content. Unless you know the density of the gas, it is the only proper way to determine the amount of energy within a volume of gas. At any rate, to demonstrate how absolutely stupid the Climate Change crowd has become, they now acknowledge that Solar UV light affects atmospheric energy. However, they claim it only affects distribution of Earth's atmospheric energy. In other words, the sun could quadruple its UV output, but the Earth's average temperature metric would not change, according to those idiots. So what good is their temperature metric ? They themselves state it is now irrelevant.

[palmer]

You are right about that. There are many weather effects from the sun, especially from UV and magnetic modulation of cosmic rays. Those end up trapping more heat on eath or letting more escape depending on the weather. Then there are bunch of earthly cycles (also solar-modulated to some extent) that grab heat from the atmosphere and stick it in the ocean or vice versa. At the same time those cycles let more or less heat to space, again mostly due to changes in the weather but also the simple fact of warmer ocean surfaces radiating more or less to space.

The bottom line is there were a number of generally (but not always) warming effects in the 80's and 90's from high solar activity. Then with lower activity recently there have been more or less cooling effects such as low UV. Consider too that the 80's and 90's each had one large cooling volcano, and the 00's have had none. That means the 00's should have warmed more (all other things being equal). But since we are seeing a lull in the warming, it is pretty clear that the solar effects are tending to dominate.

One other factor worth mentioning is deep ocean heat storage. That is sort of the last resort for the warmers now that the atmosphere and upper ocean are not warming as fast. But deep ocean heat storage means no global warming, as simple as that. If it "comes back" (a fairly meaningless concept) it will have almost no warming effect.

This debate actually goes all the way back to the ozone hole. And the same scientific mistakes were made. Assumed Solar UV output did not vary significantly. If you actually understood why visible light did not vary significantly even though there was obvious changes in magnetic activity, then there was no way you could ignore possible significant UV or Infrared changes. They simply did not grasp the science of the situation. And we may have finally found out what we have been debating for over a couple of decades. Read the free chapters of this new book. It makes you want to cry. Hat tip WUWT.

The Sun affects our weather? Amazing.

Next they’ll discover that sunspots affect radio waves (yeah, I know).
