Get ready to embark on an expedition. Starting with the air quality deterioration in Chicago, we highlight a hazardous effect of temperature inversion especially when combined with Canadian wildfire smoke. Witness how Asia sweats with extreme heat reaching a staggering 128 degrees Fahrenheit in Iran and how the Lut Desert, possibly the hottest place on earth, withstands surface temperatures of up to 177 degrees. Then, we zoom over to the United States, where temperatures in Texas, Oklahoma and Arizona scorched today with 109° - 114 degrees heat and 8 cities reached 100°+ in Louisiana with high humidity. We wrapped up with the day's highest temperatures in Africa and Europe. Tune in and develop a newfound appreciation for the world's weather conditions.
