This week, President Trump formally began the process of withdrawing the United States from the Paris Climate Accord. This is irresponsible at best and dangerous at worst.

Immediately, several candidates took to Twitter to reiterate that they would restore America’s global leadership in the fight against climate change:

Another reason it is CRITICAL we make @realDonaldTrump a one-term president. The next president has the ability to stop this withdrawal & begin to mend the damage Trump has done. As president, I’ll restore our leadership to mobilize the world in tackling this existential crisis. https://t.co/E4IHs7mACr

As the climate crisis worsens each day and California burns and Iowa floods, Trump continues to abandon science and our international leadership. He just notified the United Nations of our official withdrawal from the Paris Agreement. It’s shameful. https://t.co/5UikQrsS3u

Trump is putting polluters above people. This is the wrong move. When I’m President, we’re rejoining the Paris agreement. Day 1. https://t.co/WbBzdVS6Vh

This afternoon, this president formally began America’s withdrawal from the #ParisAgreement, a year-long process for a catastrophic decision that could affect our country—and the world—for generations.

Obviously leaving the Paris Agreement is a mistake. But we need to be honest that the Paris deal didn’t go far enough. If the US wants to regain global leadership on climate we need to make more ambitious commitments. Time for Paris 2.0.https://t.co/X0uzzDtHp5 https://t.co/IjDMsnbRWL

On my first day as President I’m getting us back into the international climate change agreement. https://t.co/bd7udbtAqo

Donald Trump is an international embarrassment. https://t.co/djiVjPXDCM

The climate crisis needs a global solution. Donald Trump’s blatant rejection of the Paris Agreement creates a leadership vacuum and will slow down international cooperation on climate. He is dragging the world backwards, and putting American lives at risk.

By leaving the Paris Climate Agreement, Trump is ceding American leadership and giving away American jobs in the clean energy economy of the future. We should be leading the fight to end the climate crisis—and I’ve got a plan for that. https://t.co/ILEBmxsiCL

Also this week, five of the candidates — Cory Booker, Pete Buttigieg, Kamala Harris, Bernie Sanders, and Elizabeth Warren — participated in the Weather Channel’s primetime special on climate change. The one-hour program, which also included three of the Republican presidential candidates challenging President Trump, set the stage by first reviewing the scientific consensus on climate change and the urgent need for action. The program then moved through several important elements of the climate crisis, including environmental justice, infrastructure, and solutions. The Weather Channel also asked the candidates what about the climate crisis keeps them up at night.
