From some tiny portion of the wealth the west accumulated in a hundred years of filling the atmosphere with carbon.

Remember...this year has already seen more billion-dollar weather-related disasters than any year in US history. Last year was the warmest ever recorded on planet Earth. Arctic sea ice is near all-time record lows. Record floods from Pakistan to Queensland to the Mississippi basin; record drought from the steppes of Russia to the plains of Texas...This is what climate change looks like in its early stages.

If the Holy Spirit is capable of the heavy lifting required to get Pat Robertson to change his mind, then that strikes me as a very good sign.

We can either save the planet from catastrophic warming, or protect fossil fuel CEOs. Not both. Do the math(s)

It was huge mistake to avoid working with the rest of the world because (a) we're the largest source of the problem: 4% of us who are in the U.S. produce 25% of the world's carbon dioxide.

My goal was to have as many of the primary sources as I could made available for people to look at and understand. Climate change is probably the most important thing that's ever happened, and yet people's understanding of it and its history remains a little fuzzy.

We have assumed control where once we worked with what we were given.
