In environmental news, a series of recent measurements are raising alarm bells about the accelerating climate crisis. Temperatures in Antarctica soared last week to nearly 70 degrees Fahrenheit. The World Meteorological Organization is reviewing the temperature reading to decide whether it qualifies as the continent’s hottest temperature on record. Measurements from the National Oceanic and Atmospheric Administration, meanwhile, show the concentration of carbon dioxide in the atmosphere hit a record high Monday. And last month was the hottest January on record. NOAA says the four hottest Januaries on record have all occurred since 2016.
