A massive Saharan dust plume is moving into the southeast US, bringing technicolor sunsets and suppressing tropical storms

From June through October, it's not unusual for huge Saharan dust plumes to blow across the Atlantic. They can darken skies but also bring calmer weather and electric sunsets. Here's how they form.

Days with both extreme heat and extreme air pollution are becoming more common – which can't be a good thing for global health

In South Asia, days with both extreme heat and extreme pollution are expected to increase 175% by 2050. Separately, the health effects are bad; together they will likely be worse.
