What I learned from "Star Talk with Nei deGrasse Tyson", from the world-famous astrophysicist and comedian, on climate change:
We've doubled the CO2 levels in less than 200 years- 100x faster than by nature.
1 degree celsius would power hundreds more hurricanes, floods, tornados, and blizzards every year.
The mayors of citeis around the world... have been getting together and forming networks and signing on pacts with each other to set targets and timetables for greenhouse gas emissions.
The temperature might go up 1 to 5 degrees in a hundred years, and there is still a lot of debate about how long it would take to reach the tipping point... I don't think we need to go drastic right away.
Pope Francis worked as a chemical technician.
Even if we depleted all our non-renewable resources we still don't know if it would turn out like Venus, but we would push earth easily beyond the point where we could live.
Conclusion: I personally am somewhat relieved and not as scared about it than I was before.
