– July was the hottest month ever recorded, i.e. the hottest since about 1850 when scientific records began being kept around the world using modern thermometers. So writes Chelsea Harvey at Climate Wire via The Scientific American.
July was more than 1 degree Fahrenheit warmer than the late 20th century average. That is huge. Enormous. The surface temperature of the earth includes Antarctica and the oceans (which are deep and cold). To get an average rise of a whole degree means that some places on land are 15 degrees warmer. Some places on land were already 110 F. in July, so adding any increase at all is a severe health risk to people who live there.
