The Trump administration has approved drilling in the Arctic as soon as December.

Over the weekend, Indonesia raised the alert on Mount Agung to level IV — its highest level — as a huge plume of ash and steam began to pour from the volcano’s summit in eastern Bali.

One U.S. geologist already labeled it a “full eruption.” About 100,000 people have been asked to evacuate the area nearest the volcano, where more than 1,000 people were killed during an explosive eruption in 1963.

Local aid organizations have begun distributing gas masks and goggles to residents, reports the BBC, as well as solar-powered televisions for emergency announcements. The island’s airport has shut down and hundreds of flights have been canceled.

Should the eruption escalate, it could have worldwide climate implications, including temporarily cooler temperatures. In 1815, the eruption of nearby Mount Tambora altered weather patterns worldwide, leading to crop failures in Europe and the infamous 1816 “year without a summer” believed to be the inspiration for Mary Shelley’s novel Frankenstein.

Agung very likely won’t become a Tambora-scale disaster, but its ash and gas emissions could still block some of the sun’s rays for the next year or two. After that, however, the global climate will continue to behave as if the eruption had never happened.

You can watch live video of the eruption here.

Congress might allow drilling in the Arctic National Wildlife Refuge.

In parts of the United Kingdom Monday morning, people woke up to a blood-red sun — a phenomenon seen around the globe this year.

The color was caused by smoke that blew in from wildfires across Portugal and Spain. Hurricane Ophelia deepened the reddish hue by dragging up dust from the Sahara.

Red skies have haunted the western U.S. recently as wildfires burned in Montana and ash rained down in Seattle. This month in Northern California, 20,000 people evacuated from massive wildfires under a red-orange sky.

To understand why this happens, you need to know a bit of optics. Sun rays contain light from the whole visible spectrum. As the sun’s white light beams into the atmosphere, it collides with molecules that diffuse some of the wavelengths. On a normal day, short wavelength colors, like purple and blue, are filtered out, making the sun look yellow.

But high concentrations of light-scattering molecules in the air (like smoke particles from a wildfire) crowd out more of those short-wavelength colors, leaving behind that hellish red color.

Since climate change makes wildfires worse, we’ll be seeing a lot more of it.
