"Forests moderate local climate by keeping their local environments cool. They do this partly by shading the land, but also by releasing moisture from their leaves. This process, called transpiration, requires energy, which is extracted from the surrounding air, thus cooling it. A single tree can transpire hundreds of liters of water in a day. Each hundred liters has a cooling effect equivalent to two domestic air conditioners for a day, calculates Ellison."

It's now part of my new #Tegtmeier project: figure out how much eg. European and American land use change has impacted local, regional and continental weather. See above posting where I asked this question, too.
So I plot #treering widths alongside d18O from #speleothem (eg. stalagmite). Both proxies are precisely dated and (can) have annual resolution.
I would expect to see a warming =
trees grow more when, at locations from where "their weather comes", other forests are felled .
And a drying =
d18O increase in speleothems.I use #GoogleEarth and my rudimentary history knowledge to determine certain locations in Australia, New Zealand, USA and Europe. tbc.πΏ

[as someone who has dove many, many times in the PNW, I am not sure I want that collection task ~wink~ ]
