Don't shoot the messenger,... BUT not much has changed since the first earth day poster (in 1970) illustrated an inconvenient truth about human nature!
Basically until people on the left and right side of the political spectrum realize that we ourselves are the enemy,... humanity will continue to die a slow painful death caused by a thousand cuts!
Given human nature, few are brave enough to face head on a problem that is technically complicated,... thus has an uncertain future of deleterious effects,... which somehow will have to be mitigated w/ infrastructure that somehow has to be paid for (with a price tag that will impact everyones comfort and lifestyles).
Consider,... even if humanity in general was magically able to grasp the basic science of man made climate change (which is,... the combustion of various hydrocarbon fuels like: coal, methane, gasoline, diesel, etc.... creates CO2 a greenhouse gas that traps infrared energy the earth's atmosphere for a very long time),...
...the human nature problem is,… looking at what is creating the excess CO2 (that the planet cannot absorb) we see it's the so called "american dream" (i.e. a fancy house w/ all kinds of creature comforts, an SUV for personal transportation, copious daily amounts of animal protein at every meal AND an annual vacation in an exotic location - which requires an airline flight)
Point being aspirational personal consumption expectations are ingrained in consumers (not just in the USA but also all around the world),... so it is and continues to be an uphill battle to educate people about the big picture science (which is the first step toward solving the problem).
Said another way,... "simplistic" one dimensional solutions,... like the idea that, getting rid of capitalism is going to "magically" solve the problem of climate change,... won't change change a thing (AND only digs the hole we are in deeper).
Fact is the capitalistic system which allows incentives for people,... will be needed to develop and build public infrastructure to adapt and correct for man made climate change.
Consider the alternative,... a system lacking economic incentives for people,... IOW cuba, venezuela, and the former USSR,... seems these economic/political systems are in greater turmoil than capitalistic systems (i.e. the USA, western europe, japan and "capitalistic" china),... bottom line if there are no economic incentives to address man made climate, what is going to nudge people to develop goods and services to fix the issue???
