I don't know any scientific data about climate change, but how about we as a world start working on less pollution rather than worry about all the little things that might matter down the road but are overshadowed by all the stupid things we are doing. Example: we worry about putting up solar panels and windmills for energy to be "green" but in the process we dump all our trash in our water, backyards, cut down trees and destroy the natural habitat creating "green energy".
Maybe we start living like we have a finite amount of resources. We do not have an infinite amount of land, clean water, or food. The goal should not be to build as big of cities as we can with as many people as we can. This exhausts all of our resources and takes a toll on the environment. Lets try to clean up what we have, create jobs for everyone we have, make food for everyone we already have, and then if the world is still "healthy" then we can work on expanding and growing.
The problem with our society is that we measure success through growth. Growth does not mean anything if it takes a bigger toll on the people and the environment. but it will get you re-elected for office. In the process we pollute everything around us and create "climate change"
