There are skeptics who do not come to their view because they have a source of income from carbon polluters.

I've learned the importance of changing people's minds at the grassroots level so that whoever does run will have a much better chance of encountering public opinion that reaches a critical mass and brings about a change not only in White House policies but in the Congress and in the state legislatures and all around the world.

The misconception that there is serious disagreement among scientists about global warming is actually an illusion that has been deliberately fostered by a relatively small but extremely well-funded cadre of special interests, including Exxon Mobil and a few other oil, coal, and utilities companies. These companies want to prevent any new policies that would interfere with their current business plans that rely on the massive unrestrained dumping of global warming pollution into the Earth's atmosphere every hour of every day.

The truth about the climate crisis is still inconvenient to the large carbon polluters. And so they want to bob and weave and dodge the truth, and pretend like it's still a big controversy, and it's not. They want to pretend that this is up for debate. Like, whether or not the world is round is up for debate, or whether the moon landing really took place.

Throughout history, religious wars have always been the most brutal and cruel and merciless.

Believe in the power of your own voice. The more noise you make, the more accountability you demand from your leaders, the more our world will change for the better.

Science is warning us that if we do not quickly reduce the global warming pollution that is trapping so much of the heat our planet normally radiates back out of the atmosphere, we are in danger of creating a permanent 'carbon summer'.
