Ilhan Omar, a US congresswoman for Minnesota, said the recent extreme weather in the US and around the world should serve as a warning. “Climate change is here and it is an existential threat to humanity.

Natural disasters like these will only get worse unless we act as a global community to counteract this devastation.”
