2019 was the second-hottest 12 months ever recorded, NASA, NOAA, and the World Meteorological Organization confirmed at the moment. It’s a fittingly disastrous near the hottest decade on report. The information follows an identical announcement final week from the Copernicus Climate Change Service, an initiative of the European Union.
The one 12 months that beat out 2019 was 2016. That 12 months noticed world common floor temperatures that have been simply 0.04 degrees Celsius higher than 2019.
2019 broke different information as properly. Europe experienced its hottest year since record-keeping started. It was the warmest 12 months documented for the oceans, in accordance with a examine revealed within the journal Advances in Atmospheric Sciences. It was additionally the second-wettest year in the US, NOAA reported final week.
It’s no coincidence that 2019 was such an uncommon 12 months for the books, consultants say. All of it indicators that local weather change is already remodeling the planet. “We’re experiencing the impacts of world warming unfolding actually in actual time,” Stanford Earth science professor Noah Diffenbaugh advised reporters throughout a press name this week.
Burning fossil fuels has already heated up the planet to 1 degree Celsius above preindustrial ranges (throughout the latter half of the 19th century). The 2015 Paris local weather accord sought to restrict warming from rising 2 levels, however scientists have since argued that, by then, the world may lose 99 percent of its coral reefs and see 70 percent of its coastlines shrink below rising sea ranges. The World Meteorological Group predicted that present ranges of carbon dioxide emissions will doubtless get the world as much as someplace between three to five levels of warming by the top of the century.
“The 12 months 2020 has began out the place 2019 left off – with high-impact climate and climate-related occasions. Australia had its hottest, driest 12 months on report in 2019, setting the scene for the massive bushfires which have been so devastating to folks and property, wildlife, ecosystems and the atmosphere,” mentioned World Meteorological Group Secretary-Basic Petteri Taalas in a statement. “Sadly, we anticipate to see a lot excessive climate all through 2020 and the approaching many years.”
