The planet’s temperature spiked on Tuesday to its hottest day in many years and certain centuries, and Wednesday may grow to be the third straight day Earth unofficially marks a record-breaking excessive. It is the most recent in a collection of climate-change extremes that alarm however do not shock scientists.
The globe’s common temperature reached 62.9 levels Fahrenheit (17.18 levels Celsius) on Tuesday, in line with the College of Maine’s Local weather Reanalyzer, a typical software primarily based on satellite tv for pc knowledge, observations, and laptop simulations and utilized by local weather scientists for a glimpse of the world’s situation. On Monday, the common temperature was 62.6 levels Fahrenheit (17.01 levels Celsius), setting a file that lasted solely 24 hours.
