The changes are notable, when I was a kid the Lehigh valley was AHS heat zone 4, we're up to 6 now. But it's impossible for anyone to say what will happen next, models can only factor in so many variables. I can also tell you as someone who went to college for environmental science that the subject can't be unpacked and done justice through a couple sentences. There's a lot going on with the climate currently, as we know it's always changing. And like just wing it mentioned, current science has been telling us we staved off an incoming ice age. They happen very consistently, if you are unaware of this, debating climate change isn't your bag. As
@ShadyStump mentioned, the poles flipping also happens consistently, if you are unaware of magnetic poles reversing, climate change debates aren't for you. Emissions and pollution getting pulled to the polar extremes of the earth? There is so much to know that even I won't bother debating anyone on the topic, actually I won't debate anyone on anything, personality trait I guess. We'll just have to see what happens next.
Anyone who tells you that this or that will definitely happen to the globe is probably not a source worth listening to, they can only speculate. Fear mongering is definitely a media move to make money.
Climate change denial is definitely corporate propaganda that's spread to protect their billions at our expenses.
All we can do is keep our own records and look at what we know. I have witnessed my city grow warmer every year from zone 6a to 6b and heat zone 4 to 6. The last ten years were the hottest years in recorded history. Those are facts. You can draw whatever conclusions you want from them, and of course different personality types will react differently. And these days personal opinions seem to rank hand in hand with facts so...hahah
To answer the question I got into bonsai when I was completely impoverished, and it would take a lot more than financial hardship to make me drop the hobby. The models "say" that by the time I'm an old man my area will be usda zone 7b and heat zone 7 to 8 IF nothing is done. So fortunately I will be able to keep doing my thing. I don't live near the coast so i'm good to go. Granted NJ is paying some folks a pretty penny to buy back their flooded beach front to make hurricane buffers/dunes. Wouldn't mind that either
