If he wasn’t POTUS he’d be locked in a padded cell.

The ramifications of a changing global climate will rival those of Islamic State attacks like the one last month in Paris, President Barack Obama said Tuesday.

In comments sure to reverberate across the Atlantic and rile hawkish congressional Republicans, Obama said the threats to U.S. and global security from climate change are already “akin” to an Islamic State terrorist attack.

Obama’s comments came moments before he wrapped up his participation in a Paris climate conference he helped organize, and echoed those of a senior White House official from Monday.

The White House ranks climate change among the top threats to the United States — and the “entire world,” Ben Rhodes, deputy national security adviser, told reporters as the first day of the Paris conference ended.

Obama struck an optimistic tone on climate change, saying, “I think we’re going to solve it.” He said the biggest issues for world leaders will be “just the pace, and how much damage is done.”

He also dismissed warnings from Republicans in Congress that they will block his $3 billion pledge to the Green Climate Fund as part of a global climate accord, saying the U.S. will deliver on its commitments.

As part of his push on the issue, Obama offered some advice for a potential Republican successor, urging GOP presidential candidates to consider, if elected, “what other countries care about.”
