WASHINGTON (AP) — Harsher storms, worsening flooding and rising seas threaten the public’s safety and health across the country, President Barack Obama warned Wednesday as he urged local communities to prepare for the effects of climate change.

Joined by top federal officials and local, state and tribal leaders at the White House, Obama said communities experiencing negative effects firsthand know that climate change is already upon us. He said boosting the nation’s resilience and fighting climate change shouldn’t be a partisan issue for lawmakers in Washington.
