2017 Was the warmest year without an El Niño Effect – 23rd January

Last year was one of the hottest years on record, second to 2016 and equal to 2015 in terms of record breaking temperatures.  The difference between these two years and 2017 is that they were both affected by an El Niño event, which boosts temperatures worldwide by affecting the Pacific Ocean. If you were to discount the natural variability in temperatures and 2017 would most likely have been the hottest year yet, according to researchers.

Scientists are now saying that man made climate change is overshadowing the influence of natural climate patterns, and that the biggest influence on the climate is now CO2 emissions from human actions.

Figures have been published by the world’s 3 biggest climate monitoring agencies; the UK Met Office, Nasa, and the US National Oceanic and Atmospheric Administration (Noaa). Their data sets show that 2017 and 2015 were extremely identical, despite the El Niño boosting temperatures in 2015.

Even when statistically levelling out the effects of the El Niño event from 2015-2016, 2017 is still the hottest year on record. This concerning trend should inspire authorities and governments to work hard towards the aims of the Paris Climate Agreement, to prevent global temperatures from rising above 2C, in order to protect against effects like extreme weather events and extinctions.
