The globe’s common temperature reached 62.9 levels Fahrenheit (17.18 levels Celsius) on Tuesday, in line with the College of Maine’s Climate Reanalyzer, a standard instrument 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 document that lasted solely 24 hours.
