Dense wildfire smoke (from forest fires in Canada) has once again moved into the NE U.S. The smoke is bringing a hazy sky this evening to the Eastern Great Lakes, and across NY and into Maryland,Virginia, and Delaware. The smoke was brought southward by the cool front that passed through last night.

A closer view of the smoke is below:

Wildfires are increasing over the western parts of North America, and it’s likely due in part to climate warming. Higher latitudes are warming much faster than tropical regions. See the image below courtesy of Climate Central.
