The consensus amongst experts was settled decades ago.
Also, a bit before the consensus was settled by geologists, meteorologists, geographers, and similar, biologists were already screaming, developing profound depression and trying to warn everyone.
Never skip the mention that the oil companies knew about it, sponsored research about it, and circulated internal memos about how it was real and what their strategies would be to spread misinformation about it even in the 1970s.
Literally the only people who don't believe in climate change are uneducated political dupes. The people they heard it from are lying for political and financial motivation.
We could notice something going very wrong with the rate at which species go extinct.
Extinctions are normal. Extinctions due to human settlements are higher, and not good for the local environment, but we have been modelling them for years now.
Extinction rates due to global warming? It's a catastrophe.
That makes a lot of sense. I guess it’s just crazy to me that one of our first indications is the erasure of entire species, but it makes sense that other fields of science would need to be measured over longer timelines. Thanks for your response.
I have to guess due to differences they noticed in terms of specific diseases, medical conditions, migration patterns, population changes and/or population distribution over time. IANABiologist though so I'm interested to hear the answer also.
