It is not how capitalism works. At first individuals should start prefer local production and production of more green companies. And only after that corporations change their politics. For example, there is a yearly rating of green electronics (how much green electricity company uses, how clean production is, etc.) but customers do not care. And if customers do not care, why corporations should care?

How are large corporations going to reduce meat consumption? Or reduce the number of international flights people take for vacation? How will they make entirely unsustainable industries like fast food, fast fashion, and cruise lines go out of business? To say nothing about the rampant inhumane working conditions and cruelty in those industries.

Certainly a lot of the issues are dependent upon the world's industrial infrastructure and that is not something that we necessarily have a handle on. But all the people building the new sustainable infrastructure are just regular people and individuals who decided to do something.

They aren't really far off it's just that the models don't show every feature of the climate because they are models, not reality. But regarding the broad strokes the models are accurate and relevant.
Also CNN peddles fear and useless information. They thrive on sensationalism, not by informing people.

China for example is doing a huge amount to decrease their impact, but you won't hear about anything positive in China since they must be portrayed as the enemy. That aside, the only way out of even worse global warming and the only way we can mitigate it is to move on from capitalism, and that's a non starter in the western mainstream.

Mainstream news is meant to run interference for billionaires (who of course benefit by destroying the survivability of the planet). Why would it present these issues in a clear, accurate, and understandable way?

It's a very lucrative industry now. People are making fortunes and careers on climate change. You can't expect honesty or clear information on the back of that. It is difficult to get a man to understand something when his salary depends upon his not understanding it.

My take is that a) man-made climate change is happening, and b) it's not nearly as bad as alarmists claim. [The global average temperature is projected to increase by 2-4C over the next 80 years. I'm sorry, but that's just not an "emergency." You know what is an emergency? The 4.6 We should, immediately, work to make energy cheaper and more abundant for more people, even if it increases our carbon output. Saving lives today is obviously much more important than potentially saving lives 100 years from now.

Sorry, but pretty much every scientific study disagrees with your view.
