Two Climate Change Bills, COVID Vaccine Boosters. Sept 24, 2021, Part 1

Ice-Hunting Lunar Rover Robot Gets A Landing Site This week, NASA announced that it had selected a destination for a planned robotic lunar rover called VIPER, the Volatiles Investigating Polar Exploration Rover. The mission is planned for launch in 2023, and will rove about the Moon’s south pole, mapping the location and concentration of water ice deposits. The plan is for a commercial spaceflight mission to deliver the rover to a spot near the western edge of the Nobile Crater at the Moon’s south pole. Sophie Bushwick, technology editor at Scientific American, joins Ira to talk about the mission and other stories from the week in technology and science—including tiny airborne micro-machines, an upcoming voyage for the James Webb Space Telescope, and the discovery of ancient kids’ handprints that could be the world’s oldest-known art.   Congress Is Considering Two Climate Change Bills. What’s In Them? President Biden has made many promises about slowing climate change. During his campaign, he pledged to bring the United States’ energy sector to zero carbon emissions by 2035. On Earth Day this year, he pledged to reduce total U.S. greenhouse gas emissions by 50% by 2030, and by 100% by 2050. But the key policy changes that will help the country get there remain pending as the relevant bills continue to make their way through Congress. The first is an infrastructure bill that would pledge billions toward cleaner transit and resiliency projects in disaster-stricken communities. But that measure is tied intricately with the fate of a second, $3.5 trillion budget bill that would direct billions of dollars to incentivize coal and natural gas-burning utilities to switch over to renewable energy. If both are to pass without substantial changes, they rely on consensus among the narrow majorities of Democrats in the Senate and the House—neither of which is guaranteed. New York Times reporter Coral Davenport walks through what’s in the bills, and why so much is still up in the air even after a summer of climate-driven disasters.   Behind The Booster Battle Update 9/24/2021: This week, CDC director Rochelle Walensky overruled the recommendations of an advisory panel and authorized a third dose of the Pfizer COVID-19 vaccine for the elderly and certain “high risk” individuals, mirroring an earlier FDA decision. In late August, President Biden had said that COVID-19 vaccine booster shots might soon be on the horizon for many Americans. In late August, President Biden said that COVID-19 vaccine booster shots might soon be on the horizon for many Americans. But last Friday, an FDA advisory committee voted to recommend booster doses only for people over age 65—and this Wednesday, the FDA authorized Pfizer boosters for use in the elderly and “high risk” individuals. In the republished article (which you can read on sciencefriday.com) from September 16, written before the FDA review, Kaiser Health News’ Arthur Allen and Sarah Jane Tribble examine the backstory behind the debate over boosters, and how leaders from the NIH got out in front of FDA and CDC recommendations.
