In Europe this week, Germany, Belgium, and the Netherlands recorded all-time national high temperatures, with Germany hitting 107 degrees Fahrenheit. Paris hit a high of 109 degrees Fahrenheit. These records come after June set a record for the hottest ever in Europe.

A new report, published in the science journal PLOS One, predicts that within 30 years three-quarters of the world’s largest 520 cities will experience near-catastrophic climate change. London could soon be as hot as Barcelona, Paris will feel like drought-starved Canberra, New York could become just as steamy as Virginia Beach, and Singapore will start to suffer conditions unlike any it has seen.
