This graph shows all 1,792,641 daily maximum temperatures in Texas recorded in the USHCN database going back to the 19th century. Texas had similar cold in many years, including 2011, 1991, 1990, 1989, 1983, 1963 and 1961. But Texas used to rely on fossil fuels, rather than wind. I was living in Houston during the 1989, 1990 and 1991 cold snaps.
The climate hasn’t changed. What has changed is the propaganda which has driven politicians to lunacy.
