“Those who cannot #remember the #past are #condemned to repeat it.” - George Santayana.

It’s amazing to see how that phrase holds true, not just for #political cause; but also for #environmental cause. We should look to our #scientific #history to understand what this world’s #climate was, to better #understand what we may bring upon ourselves, if we do not continue to transition to clean energy. #climatechange

#repost @granitepaintbrush It’s getting so cold lately the Yellowstone river has been steaming!😃 Of course I couldn’t resist throwing in some beautifully spherical rocks I found. When rocks are this round, but still large, you can almost be sure glaciation caused it.❄️☃ #yellowstoneriver #glaciation #geology #paradisevalley #stonestacking #montana #yellowstone #rocks #livingstonmt #mountains #sunrise #rivers #glacial
