I only play a hero here, but you are the true action heroes"

"Climate change is a global challenge and Washington ought to be leading from the front. We also knew many people around the world would conclude wrongly that America was walking away from climate action. Nothing could be further from the truth."

Let's marshal our forces and move to the front because as we say in the military you cannot lead from the rear. Ask yourself, if I could solve this climate crisis knowing that would come at the cost of my political career, would I do it? As far as I'm concerned there is only one answer."

The international effort to fight climate change got injected with a bit of Hollywood flash, a lot of Wall Street green and a considerable dose of cheerleading rather than dry treaty negotiations.
Business leaders, mayors, governors and activists from around the world are gathering this week in San Francisco for the Global Climate Action Summit, where participants will trumpet what they've done and announce new efforts to slow a warming world.
It involves trillions of dollars of pledges for spending on cleaner energy and getting out of investments in heat-trapping fossil fuels, according to officials involved.
And it will include a newer way of fighting climate change by emphasizing more climate-friendly land use, food production and diets, along with massive increases in forests — something one expert called "the forgotten climate solution."
Cities, states, businesses and charitable foundations are all going to get in the act.
A new report says businesses and lower levels of government have the potential to cut enough greenhouse gases emissions to keep global warming below the danger point of another 2 degrees Fahrenheit (nearly 1 degree Celsius) from now.
However, the same report says so far, 8,000 pledges from those groups haven't accomplished much.
To keep from hitting that 2 degree mark, the world has to cut its expected annual emissions by nearly 15 billion tons of carbon dioxide equivalent by 2030, including what's pledged in the 2015 Paris climate agreement.
This week's summit aims to create momentum for 2020 when world leaders return to the bargaining table to pledge even deeper cuts of heat-trapping emissions than set out in 2015, said Christiana Figueres, the former top United Nations climate official. She proposed this summit right after the Paris agreement was signed.
