Inside the UN's fraught climate huddle

State of play: The meeting, called by U.N. Secretary-General António Guterres and British Prime Minister Boris Johnson, featured an unusually candid exchange of views between world leaders, a member of a climate negotiating team who observed the meeting told Axios.

• Wealthy nations' failure to deliver on their 2009 pledge of $100 billion in annual financial assistance to the developing world — first promised in 2009, emerged as a major source of distrust and anger, the member said.
• Jochen Flasbarth, Germany's deputy environment minister, told the AP the meeting was “very frank and outspoken — not polite."

Threat level: There are huge gaps remaining between the emissions cuts countries have pledged to make and what is needed in order to keep the Paris Agreement's 1.5°C (2.7°F) target viable.

• The U.N. warned last week that if all current emissions pledges are fulfilled, the world would still warm by 2.7°C (4.9°F) above preindustrial levels by 2100.

What we're watching: President Biden is scheduled to speak at the U.N. at 10am ET, and he is expected to announce additional U.S. funding.
