Smoke from wildfires across the western United States and Canada is swirling across much of the continent, including thousands of miles west on the east coast.
Experts say the phenomenon is being increasingly prevalent as humans-induced global warming stirs larger and more intense blazes.
Smoke pollution took an unhealthy toll this week in communities from Washington State to Washington D.C, including Philadelphia, Pennsylvania.
Get used to this, the researchers say.

‘These fires are going to be burning all summer,’ said smoke expert Dan Jaffe of the University of Washington.
Scientists are associating smoking exposure with long-term health problems, including reduced lung function, compromised immune system and higher rates of flu.
Medical officials and health authorities say people at risk can arrive at hospitals on short notice and sometimes die of excessive smoke.
