"Upward of" 10,000 trees near giant sequoia groves have been "weakened by drought, disease, age and/or fire" and must be removed in the wake of California's wildfires, the Sequoia and Kings Canyon National Parks announced.
Why it matters: The damage to these trees, considered "national treasures," and work to remove them means a nearby key highway must remain closed to visitors as they have "the potential to strike people, cars, other structures, or create barriers to emergency response services," per a statement from the national parks.
Saudi Arabia on Saturday pledged to reach net-zero greenhouse gas emissions by 2060, deepened its 2030 targets and joined an international coalition seeking to cut emissions of the potent planet-warming gas methane by 30% in nine years.
Why it matters: The pledges from the world's largest oil exporter come just before COP26, a key United Nations summit opening Oct. 31 that is aimed at rallying worldwide actions to stem emissions that are currently on pace to bring global warming well beyond the Paris Agreement goals.
