I've been noticing strange sunsets lately in New Mexico where the sun looks like a molten ball of red as it sinks into the west. It's one symptom of wildfire smoke in the sky and a sign of another brutal wildfire season in the US.
The National Weather Service office in Aberdeen, South Dakota, tweeted on Tuesday: "You've probably noticed the persistent hazy skies as of late. Turns out we're not the only ones seeing this -- smoke from wildfires is covering much of the lower 48."
Besides apocalyptic-looking sunsets and orange skies, wildfire smoke can impact air quality far from where a fire is actually located. The wildfires, many of which are burning in the western US, have been fed by severe drought conditions and heat waves. These events have been exacerbated by the climate crisis and the extreme weather it brings with it.
The National Weather Service shared a fire and smoke map from the AirNow air quality monitoring site. What's notable are the wide swaths of gray indicating smoke coverage over the US and Canada, as well as the many marked wildfire locations, denoted by the orange fire icons.
