2020 is on course to be the warmest year on record
Source: World Economic Forum, Date: , 2020
While this year will be memorable for many
reasons, it is now more likely than not that 2020 will also be the warmest year
for the Earth's surface since reliable records began in the mid-1800s.
This is all the more remarkable because it
will lack any major El Nino event - a factor that has contributed to most prior
record warm years.
However, with three months remaining,
there is still some uncertainty. There is a chance that a growing La Nina in
the tropical Pacific may drive cooler temperatures leading to a second-place
finish - at least in some of the global temperature records produced by
different groups of researchers around the world.
