The Highest Temperatures on Earth

In 2010, the most-common value of near-surface air temperature was near 25 °C and a thin tail reached to 50 °C (albeit with very few points above 40 °C). Confirmed temperatures over 50 C had not occurred till then. 

Only five days ago, one of the top-three highest temperatures ever measured on the planet at any time has been recorded at California - 54.4 C. Some climatologists consider 53.88 C readings recorded in California on June 30, 2013, and in Kuwait and Pakistan in 2016 and 2017, respectively, as the highest ever reliably measured on the planet.

A study projects that if greenhouse gas emissions continue at a high rate, temperatures in parts of northeastern India and most of Bangladesh will exceed a deadly threshold during seasonal heat waves. Extreme heat waves that now happen once every 25 years will become annual events with temperatures close to the threshold for several weeks each year, which could lead to famine and mass migration.
