Joe Biden holds virtual climate event on Earth Day

Democratic presidential nominee, Joe Biden held a Earth Day town hall, virtually Wednesday from Wilmington, Delaware.

Biden's guest for the event was climate activist and former Vice President Al Gore, who hours earlier had endorsed Biden as the Democratic presidential nominee.

Al Gore who also joined virtually from Nashville, Tennessee used the climate event to reiterate his stand for Biden as president.

"Your election is absolutely crucial, Joe. And I want to do everything I can to convince everybody that cares about the climate crisis, particularly those people that this is this is a no brainer. This is a real simple choice. And if anybody has any doubt about that, come talk to me right now," he said.

Gore said Biden has asked him to help "strengthen" his climate policies.

Both leaders were critical of Trump's policies on climate change.

"Donald Trump is the face of climate denial globally. He is lifting the constraints on polluters, putting more pollution into the atmosphere, making all these changes to all of the protections that we do now have," Al Gore said.

"Beating Trump won't end climate change, but it's a critical first step," Biden said.

Biden last year unveiled a plan that would spend $5 trillion over 10 years, with $1.7 trillion coming from the government.

But his timelines for reducing carbon emissions fall short of what some climate activists demand.
