There are many who still do not believe that global warming is a problem at all. And it's no wonder: because they are the targets of a massive and well-organized campaign of disinformation lavishly funded by polluters who are determined to prevent any action to reduce the greenhouse gas emissions that cause global warming out of a fear that their profits might be affected if they had to stop dumping so much pollution into the atmosphere.

As human beings, we are vulnerable to confusing the unprecedented with the improbable. In our everyday experience, if something has never happened before, we are generally safe in assuming it is not going to happen in the future, but the exceptions can kill you and climate change is one of those exceptions.

I remain optimistic that ultimately free speech and a free press where individuals have access to the dialogue will have a self-correcting quality.

Remember that the problem is bigger than the car you drive or the types of lightbulbs in city hall. We need a fundamental shift away from dirty fossil fuels that spew carbon pollution. To make that happen, we need to put pressure on our leaders to take the bold actions necessary to move us off dirty sources of energy.

The science linking the increased frequency and severity of extreme weather to the climate crisis has matured tremendously in the last couple of years.

There are many who would much prefer that the word 'climate' never be mentioned and that the issue be eliminated from our national conversation.

A lot of people go straight from denial to despair without pausing in the middle and doing something about it.
