![]() Note that some areas in Texas are colder than Maine and even Alaska. White colors equate to temperatures around 0☌ (32☏). Areas outside of the southern and central U.S. The darkest blue areas are where the model indicates temperatures reaching as low as -35☌ (-31☏). Data for the map were derived from the Goddard Earth Observing System (GEOS) model they represent air temperatures at 2 meters (about 6.5 feet) above the ground on February 15, 2021. The map above provides a view of the extreme cold associated with the arctic air mass. He noted that Texas is the only state that has isolated its power grid from the rest of the country. Large area outages are rare in developed countries, yet this outage spans the entire state of Texas. But according to Miguel Román, director of the Earth from Space Institute at USRA and a principal investigator of the “ Black Marble” research team, this event is unique. ![]() The team has produced power outage maps for years. Data are processed by a team of scientists from NASA’s Goddard Space Flight Center (GSFC) and Universities Space Research Association (USRA) to account for changes in the landscape (such as snow cover), the atmosphere, and Moon phase. ![]() VIIRS has a low-light sensor- the day/night band-that measures light emissions and reflections. The nighttime lights data were acquired with the Visible Infrared Imaging Radiometer Suite (VIIRS) on the NOAA–NASA Suomi NPP satellite. Nighttime lights data have been overlaid on Landsat imagery so that city structure can still be distinguished. Central Standard Time on February 16 the left image was acquired around the same time on February 7, prior to the severe cold spell. Satellite data for the right image was acquired around 1 a.m. Many of those outages continued into the next day and are apparent in the images above depicting nighttime lights. The Houston Chronicle reported that 4 million customers across the state were without power on February 15, including 1.4 million in the Houston area. Demand intensified after the polar air mass moved in on February 13, and controlled outages and downed power lines left parts of the state in the dark. According to news reports, natural gas shortages were already limiting power generation across Texas prior to the mid-February storm. The extreme cold combined with several snow and ice storms to leave millions of people without power. He was, they said, too controversial.A potent arctic weather system chilled much of the United States with frigid weather in mid-February 2021, shattering low-temperature records in the middle of the country. Now there's this: Last week, on a party line vote, white Republicans forced the state's Black Caucus to remove from its Black History Month resolution the name of the quarterback who ignited a national furor in 2016 when he began kneeling during the national anthem as a protest against police mistreatment of African-American people. We've careened from blackface confessions in Virginia to Liam Neeson recounting the day he went looking for some random "black bastard" to kill, to coffee baron and would-be president Howard Schultz explaining how he doesn't see color (speaking of tired tropes), to a white teacher in North Carolina telling black students they were bound for jail because they wore athletic gear and that, by the way, Martin Luther King committed suicide. Kaepernick comes smack in the middle of what has already been one of the more bizarre Black History Months in recent memory - indeed, a Black History Month that explains why we need Black History Month.
