Satellite data shows globe will stay below 1.5°C target at the current rate of warming, resulting in 1.1°C
The average temperature of Earth’s atmosphere has warmed just over four tenths of a degree Celsius (almost three fourths of a degree Fahrenheit) during the past 37 years, with the greatest warming over the Arctic Ocean and Australia, said Dr. John Christy, director of the Earth System Science Center at The University of Alabama in Huntsville. Microwave sounding units on board NOAA and NASA satellites completed 37 complete years of collecting temperature data in November, giving us nearly global coverage of climate change during that time.
If that trend was to continue for another 63 years, the composite warming for the globe would be 1.1 C (about 2 degrees Fahrenheit) for the century, Christy said. That would put the average global temperature change over 100 years…
