Temperature graph

Levity is fine by me, but I'll use your graph in a different way. Mid-1930's had remarkably bad climatic conditions in US. But it was not global; at global scale the following decade was hotter. Quasiperiodic ocean sloshes (ENSO, PDO, AMO and there are a few others) could not have done this individually.

But maybe in combination? I honestly do not know. I have not read retrospectives on dustbowl climate, but it still sticks out at this regional scale.

Superb climate models (that I am confident can be developed) would simulate things like this. Current climate models are not there yet.

Secondly, June month max Ts are graphed. As one goes deep like this (compared to annual averages), the range of variation increases. We could talk about why this is, but enough for now to say it is a property of probability functions and not just of climate data. This graph tells me that range of variation was larger in the pre-Bob-driving era. +CO2 is having effects beyond +T, and these are not often considered. More often we hear that climate is becoming more variable. In some ways it is becoming less variable. Complicated stuff.

Thirdly, there have been changes in how various factors including max T have been measured over time. Readers may have heard of that as basis for climate-change 'hoax'. Which it most assuredly is not. However, methods changes are best done with intercalibration periods happening before the handoff. In some areas I know this happens, others it does not happen, and others unknown. For max T, this may persist as a potential contributor to smaller range of variation recently. That would require some digging.

Wuz gon na talk about how max T is 'done', Stevenson screens, and other things fascinating to me. But this thread is about Bob's VW bus, which I guess had magical properties that did not disappear when he switched to hybrids and then EVs. Wow man.

 

looks like my electro cardiogram

 

Stevenson screens


Were invented by the father of author Robert Louis Stevenson. Sorry, can't help myself sometimes.

 

no apologies necessary

 

Doubtful unless they stuck electrodes to your....
Oh I'll not say it

 

trust me, i saw the graph myself

 

I prefer this visual:

 

it was cold a few centuries ago
