Ten years ago, in 2011,energy regulators already warned the state’s electric-grid operators, climate scientists had cautioned that a warming planet would cause climate chaos which might cause unusual weather,but Texas didn't prepare for the the extreme winter weather in mid-February and leaving millions without power. Now a growing body of research links climate change such as this frank snowstorm with the occurrence of the so-called polar vortex. These climate-linked disasters, and their fallout, will be increasingly difficult to manage as global warming intensifies, creating an existential threat for many communities that are most exposed to the effects of the changing climate. For now, experts who study climate adaptation say communities should invest fully in measures that have proved to work, from hardening infrastructure to developing more localized energy production.
