The NASA recently said that globally July 2018 was the third
warmest July since reliable measurements began in 1880, 0.78°C warmer than the
1951-1980 mean. The warmest Julys, in 2016 and 2017, were 0.82°C and 0.81°C, respectively.
July 2018 temperature was +1.06°C relative to the 1880-1920 base period, where
the latter provides our best estimate of pre-industrial global temperature.
The last three Julys on Earth have been the three warmest
ever recorded. But, they may also be the warmest months to occur on our planet
in about 120,000 years, reports Mark Kaufman in the Mashabable India. http://bit.ly/2wzkUNN
Even though it is incorrect to describe the July 2018
climate conditions in the global hotspots as a “new normal” climate for those
regions, NASA study finds out that global warming has greatly increased the
frequency or chance of an extreme hot summer, e.g., two standard deviations or
more warmer than average 1951-1980 climate.
The NASA paper further said, “a strong El Nino contributed
to 2015-2018 warmth. However, we will argue that the present 12-month running
mean has already reached the inter-El Nino minimum global temperature, at a
value that is above the trend line for the average”. We may have entered a period of accelerated
global warming, said the paper further.
