Record heat continues to devastate Texas with no end in sight

A prolonged heat wave in Texas is breaking records and straining the power grid.
Temperatures are forecast to remain at dangerous levels into early July.
The excessive heat has spread into Oklahoma, Kansas, Arizona and New Mexico with many areas under heat alerts.
The heat wave was made at least five times more likely due to human-caused climate change according to scientists.
The hot weather has already claimed lives and continues to threaten millions of people across multiple states.
