During 2002, almost all of Texas dealt with varying levels of drought. But the claims that it was a "historic" drought and that it was due to climate change is misinformation.
"On the heels of a historic drought that devastated crops from the High Plains to South Texas, a new Texas Department of Agriculture report released Tuesday linked climate change with food insecurity and identified it as a potential threat to the state’s food supply."
Texas has a very long history of suffering from drought conditions, especially during La Niña events. Below is NOAA's drought reporting for Texas, from 1895 through 2022, that reveals multiple periods of harsh dry conditions that have nothing to do with human caused "climate change".
Below, Texas from 1951-1956 - a seven year period of drought that was historic. At its peak, Texas had 87.6% of its lands in extreme drought conditions, per NOAA.
And below is the 1-year 2022 "historic" drought reported by the Texas Tribune. At its peak in 2022, 61.5% of Texas lands were identified as under extreme conditions.
Indeed, Texans suffered some very harsh conditions during the 2022 but those drought conditions did not rival the exceptionally long and extensive drought of the 1950's.
Regarding the "climate change" attribution for the 2022 Texas drought? Not very likely since 2022 was a La Niña year and it is well documented that Texas and other adjacent Gulf Coast states suffer dry/drought conditions when that occurs.
"Drier-than-normal conditions are observed along the west coast of tropical South America, the Gulf Coast of the United States, and the pampas region of southern South America."
