The White House has refused to draw any clear link between Hurricanes Harvey and Irma and climate change despite growing pressure from advocates and other officials.

Causality is something outside of my ability to analyze right now, Homeland Security advisor Tom Bossert told reporters during a press briefing on Monday. Theres a cyclical nature to a lot of these hurricanes. We continue to take seriously the climate change, not the cause of it, but the things we observe.

The White House will have to perform a trend analysis sometime in the future, he added.

Bosserts comments followed ones made last week by EPA Administrator Scott Pruitt, who said on Friday that it was insensitive to bring up climate change as the storm was unfolding.

To have any kind of focus on the cause and effect of the storm; versus helping people, or actually facing the effect of the storm, is misplaced, he told CNN .
