There are so many aspects of the denouement of our darling status in the grand scheme of paleoclimatology to address - but mine is, the trees and by extension, other vegetative life. I don't live next to a glacier, or a coral reef. But I am surrounded by dying trees, and my intent is to communicate their desperation.
I have already listed so many symptoms of exposure to toxic atmospheric gases upon foliage in earlier posts, but today I have come across a new one that is rather fascinating. Leaves are not merely missing pigmentation due to loss of chlorophyll, or stippling of stomata or browning and loss of tissue. Some are actually emerging deformed! Here is an assortment of hydrangea leaves, laid out on a tablecloth. The largest, at the lower edge is closest to normal, albeit half the expected size. But the rest are completely misshapen! I have no idea what this means, other than that it's exceedingly peculiar.
The next batch is from redbud trees. The largest is closest to normal - a heart-shaped leaf, that should be dark purple. Even it is damaged but the rest are not merely damaged, they initially emerged in odd conformations. I just don't know what to liken this to. Malignant tumor? A baby with two heads?
Along these lines I recommend this article about the loss of biodiversity, and how it is spiraling out of control.
