As readers of this blog know, what I see from many data sources with time scales a lot longer than "warmest since 1880"... periods of many hundreds, or even better, hundreds of thousands of years are a better benchmark for "climate" in my book.
The attached article is a good summary of some of what we know of solar climate -- we have actually been looking to some extent at solar activity since at least the 1600s ... this is a good chart from a site that the Australian government maintains that lets you look at the cycles in some detail and gives you some ideas of how much variation there is ...
Solar Cycles are quite interesting -- the article touches on the "Maunder and Dalton Minimums" and the "Little Ice Age" from about 1550 - 1850. The fact that we warmed from the "1880 on" is not very surprising if you show a temperature chart from say 10K years rather than "100 or so". Somehow the Mann / Gore "hockey stick" just isn't so interesting on THAT scale !
The current popular "settled science theory" is that CO2 created by humans largely drives the planets climate -- or at least has swamped all other effects since 1880. A short glance at a longer term chart will really make you wonder about Roman and Medieval Co2 production, and if you are not a fully "settled" warmist may even make you look at a few of those spikes and ponder if there isn't just possibly SOMETHING else out there that might account for such variations.
Then, maybe at noon some day on the beach, you look up and go EUREKA! THE SUN!!! OMG, the **SUN** affects temperature on earth!!! ... but then, if you are a "smart person" and want to stay recognized by your peers as such, you take a deep drink of cocktail and say "never mind ...
