Has anyone else noticed a real shift in the climate over the course of their lifetime? I know I certainly have

Huge change.... I mean, it's within the survival threshold of most species still but there's barely any seasonal boundaries anymore and the sun feels downright oppressive. The forest i live in is barely hanging on from a once lush and bountiful space. But the real change ive seen is in the oceans. On land it's harder to notice the absence of species that aren't surviving since they're mostly in the top inch between the ground and the air, but aquatic ecosystems are/were/should be life as a fluid, where the food web exists in every drop (even if the rule where most life exists at the interfaces still applies: between water and air, water and land, salt and fresh water, there's always a higher density of life). When I was a kid, I could jump into a constant and evolving story of life, death, birth, growth. There was kelp that grew from the bottom 20 feet to the surface, an infinite mosaic of fish species picking eggs and other organisms from the kelp, crab fighting over corpses, even those sea horses that are long and straight. I would spend hours just watching the endless drama unfolding under the surface. For more than 30 years I've been watching the decay consume the diversity and health of the same oceans and even specific reefs, trying to ignore it until 2019 when it shifted completely. On a zero visibility day where the water was filled with this red wool algae, over a carpet of crushed shells and uncovered rocks (I cant remember seeing bare rock in that area from my entire childhood) when the algae suddenly cleared and I swam into just... water. Not the life-filled web of microorganisms refracting light that's always been the medium of the ocean superorganism. The water of the north Atlantic should be much closer to blood with its cellular density and ability to absorb light, than water. Water is just the fluid scaffold that supports every scale of life *possible*... but in 2019, for the first time, i swam into a patch of water. There was still some life in it, but fuck all compared to what I'd always known. Little clumps of death where bodies of organisms aggregate after losing the strength to keep their bodies separate and swim against the natural tendency of dying microscopic life to clump together. The water had no refractive quality from the sunlight. All wavelengths of light were penetrating what should be a complete filter of the higher energy part of the spectrum. Id bet underwater photographers are noticing they're needing fewer filters to get great shots these days because there's nothing getting in the way of light that should be powering the entire food chain. It was just... water. Totally dead and empty. And below me was a carpet of bottom feeders of lobster and crab so dense they were exhausted from constant conflict with no space to feel secure, fed by the fallout of the collapse of the ecosystem above. I was staring into the void. It was the edge of existence and it was in one of the richest areas of biodiversity ive ever witnessed. Everything turned to nothing. It was the most horrifying experience I've ever had. The only thing worse was the realization that what I was seeing was happening everywhere; this patch of dead water wasn't the anomaly, the anomaly was any patch of life and healthy water. This is spreading and coming on shore. I dont understand how the entire diving community isn't shouting into every microphone that everything needs to stop until this nothingness, recedes. It's like we can live any lie as long as it means we don't have to give up our comforts... even the silencing of the living planet in our lifetimes. Nothing matters more than our individual, self obsessed narrative.
