Las Vegas is currently under an excessive heat warning that is expected to remain in effect through at least Thursday, July 11.

Las Vegas reaches unprecedented heat
This July heatwave follows the hottest June on record, according to global temperature analysis, a trend scientists believe is closely tied to global warming and the reckless burning of fossil fuels.
Excessively high temperatures pose serious health risks, particularly for vulnerable groups like young children and the elderly. The NWS has urged residents in the affected areas to drink plenty of fluids, stay in air-conditioned spaces, avoid the sun, and check on relatives and neighbors. They also warned against leaving young children and pets in unattended vehicles, as car interiors can reach lethal temperatures in minutes.
Excessive heat can cause heat exhaustion, with symptoms including cool, moist, pale skin, headache, dizziness, weakness or exhaustion, and nausea. The most severe illness caused by extreme temperatures is heat stroke, which can be fatal. Symptoms of heat stroke include vomiting, confusion, throbbing headache, decreased alertness or loss of consciousness, high body temperature (above 105°F), hot, dry skin, rapid, weak pulse, rapid, shallow breathing, and seizures.
According to the U.S. Environmental Protection Agency, more than 14,000 Americans have died from heat-related causes since 1979. The sweltering conditions have also increased the risk of wildfires spreading in California, as the dry and hot weather makes it more difficult to contain blazes. Authorities have cautioned residents to be vigilant, with the California Department of Forestry and Fire Protection advising, “Remember, one less spark could mean one less wildfire.”
