This last July was the second hottest July on record, contributing to the second warmest year on record. According to the National Oceanic and Atmospheric Administration, “The July temperature across global land and ocean surfaces was 1.49°F above the 20th century average of 60.4°F, the second highest value for July in the 138-year period of record, behind 2016 by 0.09°F. July 2017 marks the 41st consecutive July and the 391st consecutive month with temperatures at least nominally above the 20th century average.” There have been much warmer than average temperatures occurring in every continent, excluding Antarctica. Record high temps have been established in Africa, Asia, and Australia.
These unprecedented raises in temperatures have an affect around the world. Sea ice in the Arctic has been on the decline, averaging more than 16% below climatological values. The Antarctic has underachieved in sea ice extent, gaining 4.5% less than the climatological values.
