— On Feb. 3–4, the wind chill at 6,288-foot Mount Washington in New Hampshire dropped to 108 degrees Fahrenheit below zero — the coldest wind chill on record in the U.S — and the temperature hit 47 below. These extremes stemmed from the polar vortex, along with powerful winds, “resulting in dangerously low temperatures, power outages and canceled flights” in parts of the Northeast.
—The mercury dropped to a record low for Feb. 4 at Boston Logan International Airport in Massachusetts: 10 degrees below zero. The previous record (2 below) was set 137 years ago. Also on Feb. 4, Portland in Maine experienced its all-time record low wind chill: 45 degrees below zero.

Zero drought or abnormal dryness in New England and relatively small areas of abnormal dryness in the Northeast as of 7 a.m. (EST) on March 7, 2023. That’s a major improvement compared with conditions on Aug. 30, 2022. Nearly 2 percent of the Northeast was in an extreme drought, 11 percent was in a severe drought, nearly 24 percent was in a moderate drought and 59 percent was abnormally dry.

This map shows average net surface emissions and removal of carbon dioxide, a major greenhouse gas linked to global warming and climate change, from 2015 to 2020. Countries where more carbon dioxide was removed than emitted appear as green depressions. Countries with higher emissions, including the United States, China and India, are tan or red and appear to pop off the page. The level of carbon dioxide (the largest contributor to human-caused warming) in the atmosphere has increased by about 40 percent during the industrial era.

Me in the 1960s with lots of snow at our home in Brighton, New York. We lived several hundred yards south of Rochester, which is along Lake Ontario. I did a lot of shoveling when I was growing up. The white stuff was often lake-effect snow.
