The Five reacted to a speech Leonardo DiCaprio gave regarding climate change at Yale University.

Flanked by former Secretary of State John Kerry, DiCaprio said the planet is in grave peril:

"Vote in next year's midterm elections for politicians and candidates who admit climate change is real," DiCaprio said.

"Make sure the next administration believes in the science of climate change," he said.

Kimberly Guilfoyle said DiCaprio was participating in the "climate stretch," wherein the "Titanic" star was exaggerating the current conditions slightly.

However, she credited DiCaprio with sitting down with then-President-elect Trump last year to discuss climate change.

Juan Williams said that rising ocean levels and temperatures could indeed lead to stronger tropical systems, like Harvey, Irma and Maria.
