WASHINGTON, D.C. (CNN) – Last month was the hottest June ever recorded on Earth.
The National Oceanic and Atmospheric Association (NOAA) said the average global temperature was 1.7° Fahrenheit warmer than the 20th Century average.
Record temps affected Europe, Asia, Africa, Canada and South America.
The heat also brought Antarctic sea ice coverage to a record low, according to NOAA.
The report was released as several cities in the northeastern U.S. prep for a dangerous heatwave.
