A study focusing on Texas last summer reveals that the apparent temperature, or heat index, is increasing three times faster than the measured temperature due to climate change, with the relative humidity remaining constant as the temperature rises, reducing the body's ability to cool through sweating. The study's revised heat index model shows that the apparent temperature at Houston's Ellington Airport on July 23 of last year was 167 degrees Fahrenheit, with climate change accounting for 12 degrees. The lead author warns that extreme heat conditions in Texas may become hyperthermic for all and emphasizes the need to reduce additional warming by ceasing the burning of fossil fuels.

A new study shows that the heat index, which measures how hot it really feels, has increased much faster in Texas than the measured temperature, with extreme days feeling 8 to 11 degrees Fahrenheit hotter due to climate change. The study highlights the dangers of rising temperatures and the need to communicate heat stress accurately to the public. Researchers emphasize the importance of ceasing additional warming by stopping the burning of fossil fuels. The study also suggests that people need to take precautions to avoid hyperthermia, especially in extreme heat situations, and that the current heat index calculations are inaccurate in today's climate conditions.

A study supported by the National Institutes of Health predicts that cardiovascular-related deaths due to extreme heat will increase in the United States between 2036 and 2065. Older adults and Black adults are expected to be disproportionately affected, as they often have underlying health conditions and face socioeconomic barriers that can influence their health. The study estimates that each summer, about 71 to 80 days will feel 90 degrees or hotter, leading to a projected increase in annual heat-related cardiovascular deaths from 1,651 to 4,320 for the general population. The number of deaths could more than triple if greenhouse gas emissions rise significantly. The researchers emphasize the importance of taking extra steps to avoid extreme temperatures, especially for those with underlying health risks.

Record high temperatures were reached today at all three airports in the Washington D.C. area, with temperatures in the upper 90s, and are expected to be broken again on Tuesday. The combination of high temperatures and humidity could result in heat index values near 105 degrees in some areas. It is advised to stay hydrated, seek shade and air conditioning, and check on those who may struggle with the heat.

Meteorologists have issued a heat advisory for Rochester and the surrounding area on Labor Day, with temperatures expected to reach the 90s all week. This follows a national trend of September feeling more like August. The heat and high humidity may lead to heat illnesses, prompting warnings to stay hydrated, stay in air-conditioned rooms, and avoid strenuous activities during the hottest parts of the day. The Democrat and Chronicle will release a podcast called "City on Fire" exploring the effects of heat and violence in Rochester, as temperatures continue to rise due to the climate crisis.

Over a dozen high school football games in the Kansas City area have been delayed due to dangerous temperatures. The decision to delay the games was based on heat index readings and the wet bulb globe thermometer, which measures heat-related stress on the human body. The National Weather Service has extended the Excessive Heat Warning until Friday evening, with temperatures reaching the upper-90s and heat indexes between 110-120 degrees. Relief is expected with a cold front bringing temperatures down to the 80s and some rain chances on Sunday.
