I have been thinking of Earth Crisis, the sixth extinction and futures.
Paleontology proves such catastrophic shifts in abundance and diversity of life have happened before, and more quickly than one might imagine.
This time, the trajectories of evolution ahead of us, or the new biogenics of Earth systems, have been irreparably skewed or deviated by anthropogenic activity. Even an ice-age predicted by Milankovitch cycles has been prevented. The bitter truth is that, for a long while, certainly since the Rio summit of 1992, these harms have been a conscious effort ~ the first time in Earth’s history. … Read more
I am at Monknash SSSI on the South Wales coast, protected for its abundance of special geology and rare species. A handful of humans and our canine companions are wandering the beach towards Cwm Marcross, beneath magnificent Liassic cliffs just West of Nash Point. We are all separate in our own worlds, though sharing the common experience of listening to the cackling of fulmars on narrow ledges and tracing our way along the shore. The steep, stratified layers of the cliffs are a rhythmic repetition of limestone and mudstone, and formed as a late Triassic desert was inundated by ocean. Molluscan faunas found here by paleontologists have provided a surprisingly detailed record of environmental history, particularly in rarer tufa limestone deposits. … Read more
