Thank you, President Biden, for bringing us together to focus on the existential threat of climate change.
You have started this summit by walking the talk, and I applaud the commitment of the United States to cut greenhouse gas emissions 50 to 52 percent below  levels.
Mother Nature is not waiting.
The past decade was the hottest on record.
Dangerous greenhouse gases are at levels not seen in 3 million years.
Global temperature has already risen 1.2 degrees Celsius – racing toward the threshold of catastrophe.
