Two dead and two in critical condition after lightning strike near White House

Scientists say that the climate crisis is increasing the likelihood of lightning strikes across the United States, after lightning struck at a square near the White House, leaving two people dead and two others in critical condition.

The District of Columbia fire and emergency medical services department said the four people were struck in Lafayette Park, located directly outside the White House complex.

They were all taken to local hospitals in critical condition after passersby administered first aid. A portion of the park remained closed on Thursday evening, with emergency crews at the scene.

While details of the strike remained limited, the Washington Post reported it was the result of a large thunderstorm that swept through the city in the evening, unleashing high winds and severe weather.

The hot, humid conditions in the capital were primed for electricity. Air temperatures topped out at 94F (34C), or 5F higher than the 30-year normal maximum temperature, according to the National Weather Service.

More heat can draw more moisture into the atmosphere, while also encouraging rapid updraft, two factors for charged particles, which lead to lightning.

A study released in 2014 in the journal Science warned that the number of lightning strikes could increase by 50% in this century in the US, with each 1.8F of warming translating into a 12% rise in the number of lightning strikes.

John D Murphy, 22, of Boston, died of cardiac arrest after being hit by lightning while on a trip with a group from the National Outdoor Leadership School, a non-profit global wilderness school.
