>I can't agree, there are many things alive right now that I don't particularly appreciate. Including lots of people.
Yay, genocide.

>Also, they will all die anyway, the future will by its very nature be different and filled with different forms of life.
How about you colonize some other planet first? This one is currently occupied.

>The process that will allow us to adapt so easily - exponential growth based on technology
You seem to have a lot of confidence that future tech will solve our problems, but nothing we currently have under development is even coming close to being the kind of magical fix you would need.

>Taking that into account makes climate change almost a laughable priority.
"My house is on fire, but that's okay. One day I will be immune to burning"?

Also, none of what you said will do any good for any of the people who have to live between now and the day your magical adaption technology is invented, or any of the people who will be to poor to afford it.

>The temperature records we have as far as it goes
Here's a good start. We have records that go back further, but the accuracy falls away.

>I wanna see if the temperature is actually rising or if these are big ass fluctuations.
How would you distinguish the two?

>Also I want evidence that these are manmade and not natural.
That's slightly harder. Here's the short version:

Atmospheric CO2 levels have risen considerably since the industrial revolution. By looking at the isotopic ratio of CO2 in the atmosphere, we can tell that the rise is originating from fossil sources. We know from physics that CO2 is a greenhouse gas, and we can show that the contribution of human-emitted CO2 (plus the feedback from water vapor) is enough to produce between 80% and 120% of the warming seen since the industrial revolution. We can confirm that the greenhouse effect is the cause of this warming by observing the reduction in outgoing infrared radiation, using satellites.
