The El Dorado fire in California that has burned more than 7,000 acres (2,800 hectares) was caused by a firework set off at a “gender-reveal party”, the California Department of Forestry and Fire Protection (Cal Fire) has found.

The horrific fires of 2020 are just a preview. No matter what we do, two to four times as much land area will soon burn annually in the West.

Dozens of blazes continue to rage in California with a record 2.2m acres burned. Bay Area residents awoke on Wednesday to orange skies

The blazes are overwhelming the state, with at least six deaths linked to the fires.

The working definition of the ongoing brain seizure that is 2020 is either that Coloradans are being told by state authorities to install smoke-resistant “safe rooms” in their houses, or that Californians now must weigh what kind of mask to wear. An N95 mask helps to filter out harmful particulates from the wildfire smoke that is overwhelming the Golden State, but many come with an exhalation valve to keep the wearer from overheating—and that valve can spread the coronavirus.

Hurricanes, wildfires, heat waves and disease outbreaks are all a preview of our hotter future. Dramatically cutting greenhouse gas emissions would help.

A court ruling expected as soon as Wednesday could determine whether Uber and Lyft shut down across California later this week. The companies are threatening that they will be forced to shut down after a court in San Francisco last week ruled that drivers for their apps are employees, not independent contractors, under state law. The decision gave them 10 days to make their drivers employees. But the companies must retool their apps to support the employment model, corporate officials said, and cannot meet that deadline.
