LOL!! but it is the only 134 years of data we have for this beautiful county of Chester....so we analyze!!!

It doesn't matter if it's 134 years of climate data from Gibson County, Indiana. It is just one of the  3143 counties in the United States that you are trying to use as the lens from which to view global climate change from. You don't get the right to say that I'm cherrypicking when that is the flimsy pedestal you're standing on.

Welp I guess if our climate began in 1980 there could be a story there....

Any chance you could post a link to the data and/or a full-size pic of that?    Pretty hard to read as is.

A while ago I linked a report that concluded that solar+batteries were becoming cost competitive in sunny locations for 24-hour a day firm power. Here's another report with the same findings. Solar/batteries are competitive now and will only become cheaper in the future.

 The following is very interesting as regards the controversial topic of potential significant deep ocean heating from sources independent of AGW such as deep ocean seismic activity:

An anomaly in global sea level rise is explained by deep ocean heating

by David Appell, Phys.org

Scientists found that up until 2016 that the global mean sea level (GMSL) "budget," accounting for all the energy flows that create sea level rise, was "closed," but since then it has developed a hole in it. The budget is no longer closed, at least according to ocean heat data, down to 2,000 meters. Where was the missing cause for the latest sea level rise?

Now a new examination of sea level in the global ocean since 2016 has closed the GMSL budget and brought the sea level books back into order. The new researchappears in the journal Earth's Future. The paper is important for showing that deep ocean heating can no longer be ignored when considering sea level rise and its acceleration.

Deep ocean heat's growing role

In particular, the researchers, with lead author Anny Cazenave, an emeritus scientist at the Laboratory of Space Geophysical and Oceanographic Studies (LEGOS) at Toulouse, France, found that accounting for sea level rise from expansion due to added heat in the deep ocean, below 2,000 meters, allowed the GMSL budget to be "almost closed" since 2016.

"The next step," they write, "will be to determine whether the recent deep ocean change is due to internal climate variability, forced anthropogenic response or a combination of both."

@donsutherland1, @chubbsand others, your thoughts? Does this imply that deep ocean seismic activity MAY actually be an independent nontrivial source of ocean warming after all? Perhaps this may help explain the pockets of extreme ocean warming such as has been the case in the W PAC? Keep in mind that David Appell is not at all an AGW skeptic.

It's uncertain. "Internal climate variability" could concern long-period ocean circulation. Seismic/volcanic activity aren't the only explanation for internal variability. I welcome additional research. Overall, I suspect that anthropogenic and natural variables are contributing, though the anthropogenic one is probably growing relative to the impact of natural variables due to increasing anthropogenic forcing.

Manmade warming spreading from the upper ocean is the most likely cause of deep ocean warming. As implied by the following statement in the abstract: This finding reveals that deep ocean warming is gaining importance and that ocean heat uptake has now reached several regions below 2,000 m depth, notably the Northwestern Atlantic Ocean and Southern Ocean.  Figure 7 in the paper shows where the deep warming is occurring. The warming regions are associated with ocean overturning circulations not seismic activity. The paper discussion mentions that the added heat in the deep ocean is needed to better match satellite measurements of the earth's energy imbalance. Finally the underlying paper doesn't mention seismic activity at all.
