While the last decade – 2010 to 2019 was the hottest decade in recorded history, 2019 was identified as the second-hottest year ever in human history or since records are being kept, claimed researchers. This showed the impact that global warming and climate change was already having on the world and on humans.
According to research from the National Oceanic and Atmospheric Administration, the National Aeronautics and Space Administration and the World Meteorological Organization, the last decade was the period which saw six of the warmest years on record ever.
The hottest year of the decade and indeed of recorded history was 2016. Compared to 2016, the average global temperature was slightly lower. 2016 was the hottest year on record as it had an average temperature of 1.2 degrees Celsius more than the pre-industrial levels. Researchers and scientists have said that part of the reason or 2016 being so hot was the role played by an El Nino phenomenon which cause a substantial amount of heat generate din the Pacific Ocean to be released into the atmosphere.
Observation stations all across the world were put to use for analysis of the temperature data by the researchers. Compared to the global average surface temperatures between 1951 to 1980, it was almost 1 degree Celsius higher in 2019, the researchers found.
“Unfortunately, we expect to see much extreme weather throughout 2020 and the coming decades, fueled by record levels of heat-trapping greenhouse gases in the atmosphere,” WMO Secretary-General Petteri Taalas said in a statement.
“Australia had its hottest, driest year on record in 2019, setting the scene for the massive bushfires which were so devastating to people and property, wildlife, ecosystems and the environment,” Taalas said.
The Paris Climate Agreement in 2015 was the agreement that saw the largest number of countries of the world signing a single agreement. Under the accord, all the countries had pledged to keep a cap on carbon emissions globally so that the increase in the global temperature could be maintained at 1.5 degrees Celsius over the pre-industrial levels. However the countries do not seem to be on track to meet that Paris goal.
In fact, the overall average temperature on land is increasing at twice the speed of the global average, according to a warning issued by the United Nations’ scientific panel on climate change. It also noted that the global average temperature on land has increased already by the 1.5 degrees Celsius mark that had been set at the Paris Climate Agreement.
