The elephant in the room right now is abrupt climate change, but unlike the shadowstate would have us believe, by far the biggest impact is NOT human. It's all to do with solar forcing during the Grand Solar Minimum combined with Gaia lowering her magnetic shield. Here's a clip from a previous Openhand article that summarises it...

Probably the biggest impact the Sun has on the Earth (and the rest of the solar system) is through electromagnetic coupling - the impact of ionsed particles and plasma, which is in constant descending and ascending spirals to and from the Earth. Now during a GSM, although sunspot activity and Thermal Irradiance decrease, this Solar Wind activity actually increases, because it can more easily escape the sun's atmosphere. It means there's an increase in hot, fast, and highly charged particles hitting the Earth's magnetosphere. These charged particles bounce between the poles, which causes a cascading effect down through the ionosphere, which in turn greatly impacts the jetstreams. It leads not only to warming, but increased storm activity including hurricanes and typhoons. The climate impact clearly bears witness to this dynamic, where the meandering jetstreams have not only caused heating in usually cool places, cooling in usually hot ones, but also a strong increase in hurricanes and typhoons.
