Many places in the northern half of the world are currently facing record-breaking heat. Several countries in the Middle East, including Iran, Kuwait, Oman and the United Arab Emirates, recorded days over 50 degrees Celsius (122 Fahrenheit) in recent months. Moscow and Helsinki, Finland also reported their hottest June temperatures on record. Several weeks ago, there was a record-breaking heat wave in the Pacific Northwest of the United States and western Canada. Oregon and Washington state reported almost 200 heat-related deaths. Jennifer Vanos is an assistant professor at Arizona State University. She said: (Heat) is different than other extremes because…it's invisible. She added that when “it's something people have never experienced before, then it becomes a lot more dangerous." A United Nations group on climate change says cities can be dangerous places during heat waves.
