Climate Change is undeniably real.

Absolutely.

Be alive for long enough and you'll witness the changes.

I think we already have.

Extreme heat and flooding, a significant Impact on agricultural yields and rising seal levels - all of which were not affected centuries ago.

I agree, although, I meant this more on a personal level. Someone might notice record heat/cold year on year. Or they may see their local landscape change from how it looked 5-10 years ago. There's subtle and not so subtle signs everywhere. It's more believable when you see it with your own two eyes, though.
