News Peg
An excessive heat warning was in effect last week for more than half of Texas, including Dallas, Houston, Austin and San Antonio, while heat warnings stretched north to Oklahoma, as well as Louisiana and New Mexico, bringing “dangerously hot conditions” and a heat index—how hot it feels outside when humidity is taken into consideration—as high as 120 degrees in some areas. Forecasters urged residents to stay hydrated in air-conditioned rooms, avoid strenuous outdoor activity and take “extra precautions” while outside. The heat wave is expected to expand into Arkansas, Louisiana, Mississippi, New Mexico and Oklahoma this week, bringing temperatures between five and 15 degrees above historical averages, according to AccuWeather meteorologists, though heavy rain sweeping through Louisiana on Monday could hamper the heat.
Tangent
Forecasters expect the early-season heat waves to be a sign of things to come, as a weather phenomenon called El Niño develops, bringing warmer air north, and as scientists warn the effects of climate change from greenhouse gas emissions will continue to drive temperatures upward, prolong drought conditions and make wildfires more frequent and strong. Roughly 1,500 cities and towns in the U.S. broke daily heat records over a 30-day period ending last September, as heat waves spread throughout the U.S., as well as the U.K. and southern Europe. So far this year, a heat wave in China took down single-day records in China, while in the U.K., forecasters are warning of the hottest year on record.
