Some proof is already emerging. Some of the trends already look like the models. I don't want to wait until the temp has risen to start taking the science seriously; it might be too late to do anything about it by then.
From what has been taught in schools, since I was a youngster, the planet was much warmer before the last great ice age. It would make sense that the planet would eventual return to that temperature, as it recovers. All that carbon that has been hidden underground, that we are now burning, was already freely available in the atmosphere and environment. When it got really cold, lots of species became extinct, and when it gets warmer (again), lots of species will become extinct. This global warming trend, didn't just start 100 years ago, it's always been, and will continue, regardless of what we do. Maybe a little quicker with CO2, but not so much to make any difference. I believe it's self-limiting, and it can only get so hot, before it starts to cool off again. Water has a much larger role in all this, than anything else on the planet, in can exist in three different states, depending on temperature and pressure, and has a lot of influence on how everything else interacts. It is the most abundant compound on the planet.
The climate is doing exactly as expected, and still has quite a ways to go, before it returns to 'normal'. Me, I was tired of living in the 'ice age', growing up on a mountain. Moved to a warmer climate, and for the past 3 months, been living in the icy past. Climate Change scientists want us to fight the planet's natural return to warmer temperatures, claiming, that us 'deniers' just don't want to change our lifestyles. I live a reasonable life, work a little harder than I would like, not much left over for luxury. The expense of fighting Global Warming, would change my lifestyle from a small house, to a cardboard box under an overpass.
Climate Change based on man-made CO2, is shaky proof, at best. Everything else is too quickly rejected, to have been considered carefully. This battle has little to do with saving the planet, its an agenda, for political power, and financial gain.
Recycling has been around for decades, but receives little funding, and doesn't get much attention. Just not much profit in it, and actually not even cost effective. We want a cleaner planet, it's the right thing to do, but nobody wants to force it, because it doesn't produce a profit. But in the past 10 years, we are getting a huge push to fight Global Warming, to help preserve cooler temperatures for somebody's great-grandchildren, so they can pick through the landfills in relative comfort. Such a bright future...
