The state fossil of Nevada is the Ictheosuarus (I think that's right but it's why we call it icky fish) . It's cleanest example lives in a dig just south of Ione Nv at close to 7,000 ft .
My favorite example of climate change is that 10,000 yr ago the were iceburgs in Martha's vineyard , and probably sea ice every winter .
La Nina and El Ninõ are great examples of how much nature cares what we think . Marlin 15 miles off the coast Oregon and blues being a regular thing all one season off San Francisco was pretty odd . Them and the great whites are probably what has run the Salmon runs all amuck with 3-4 wet winter's and the warm Pacific current running so far north made it pretty easy for them eat a whole run which then doesn't come back to spawn .........
I also love to make the example of the volcanic vents in 5,000+ with whole ecosystems living on them in 800° F water ......heat rises and although it dissapates during it's rise to the surface if you heat enough long enough it's going to raise the temperature of the whole and probably change the flow speeds and the range of effect .
Then I run across the city dweller save the world guy ..." Do you use air-conditioning ? " , " Yeah " , " refrigerated or evaporative" , it always A/C . Then I'm like do you know what a BTU is ? Shows them the wiki dictionary answer . LA county has 8 million people in it that's 2,000,000 homes at 50,000 /hr 6-10 hr a day from April thru September . 5 times 20 , times 8 , times 180 days add 5 zeros . Divide by 640 . That's how many square miles of water you can boil 1 foot deep with the heat exchange exhausted into the air around your house ........ I wonder why it's warmer down wind , don't you ?
Sorry numbers , hot water , sulphur emissions ........
