Western countries are not the major culprit at the moment. EU has decreased their CO2 emissions by 20% during the last 30 years. USA has maintained them. China and India, increased them by 300% and China alone now emits more CO2 than USA, EU and Canada combined.
This is not to say that Western countries can just cross their arms and do nothing, but, they are not the ones that are going to change the picture and all this discourse about global warming has been turned in an anti-West political weapon that never addresses the real issues and never has the courage to point their finger at the countries that are the biggest problem at the moment.
This way, I fear no real change will happen until it's too late.
