The Arctic Ocean has warmed by about 2 degrees Celsius since 1900 and started getting hotter much earlier than researchers previously thought, a new study found.
Driving the news: The research, published Wednesday in Science Advances, shows that the Arctic Ocean began warming early last century as warmer and saltier waters flowed in from the Atlantic — a process known as "Atlantification."
Southern California is facing an intense Santa Ana wind event over the Thanksgiving holiday, with "critical" wildfire risk since very little rain has fallen in this region so far this wet season.
Why it matters: Fire danger is forecast to be highest from Wednesday through Friday, and any wildfire that ignites could become a conflagration that’s difficult to stop.
The Biden administration approved Wednesday plans for a major offshore wind farm to supply power to New York.
Why it matters: The approval for the installation of a dozen turbines near Rhode Island marks a major step in the administration's goal of reaching 30 gigawatts of offshore wind-generating capacity in U.S. waters by 2030, powering more than 10 million homes.
At $112,595, the 2022 GMC Hummer EV Edition 1 pickup truck is the epitome of a "halo" vehicle for General Motors.
Why it matters: The market for electric pickups is about to explode, and the Hummer EV, along with Rivian's R1T, are first out of the gate.
The big picture: Hummer, known for its gas-guzzling behemoth SUVs, is making a comeback as a zero-emissions sub-brand under the GMC label.
Still, the technology on this truck will blow you away.
One feature in the Hummer that's likely to permeate all of GM's vehicles is an enhanced version of Super Cruise, GM's hands-free assisted-driving system.
The bottom line: The GMC Hummer EV is too extreme for most people's tastes, but its mission is to excite people about the potential of electric vehicles.
