I'm naturally an optimist, but my basis for hope is rooted in my understanding of human nature.

The choice to 'do nothing' in response to the mounting evidence is actually a choice to continue and even accelerate the reckless environmental destruction that is creating the catastrophe at hand.

You can say the Earth is flat, but it doesn't mean you're going to fall off the edge.

The ten hottest years in the atmospheric record, going back only 160 years, have been in the last eleven years.

Humankind has suddenly entered into a brand new relationship with our planet. Unless we quickly and profoundly change the course of our civilization, we face an immediate and grave danger of destroying the worldwide ecological system that sustains life as we know it.

Some of the most intriguing new research is in the area of extreme weather events and rainfall. A recent study by German scientists published in Climatic Change projects that extreme precipitation will increase significantly in regions that are already experiencing extreme rainfall. Man-made global warming has already increased the moisture content of the air worldwide, causing bigger downpours. Each additional degree of temperature increase causes another seven percent increase in moisture in the air, and even larger downpours when storm conditions trigger heavy rains and snows.

There are skeptics who do not come to their view because they have a source of income from carbon polluters. I don't mean to imply that they're all in that category at all. There are also those who are also not motivated by ideological resistance for any role of government. But I don't know of any arguments or any presenters of arguments that overturn the consensus that I think have gained any legitimacy.
