The National Weather Service issued warnings of extreme heat and high forest fire risk in Texas, Kansas, and Oklahoma. At this time, scientists see the current heatwaves as an indicator of global warming. Dozens of cities, from California to Colorado, recorded all-time high temperatures for March. Among them are Topeka (35°C), Kansas City (33.3°C), and Cheyenne in Wyoming (28.3°C). Other cities, such as Denver, Grand Island, and Midland, also set all-time daily temperature records. A record-breaking heatwave hit the southwestern United States on Saturday, moving toward central regions, bringing unusually high temperatures after a week of extreme cold.
