Our planet’s surface was warmer last month, with temperatures since January tracking those of the hottest ever calendar year back in 2016.
According to the Copernicus Climate Change Service, this year has now faced three months of record warmth in January, May, and September. Such climate changes are truly worrying, and researchers released a full statement. Here is what you need to know.
The Hottest and the Most Dangerous
For the 12 months through September, Earth was around 1.3 degrees Celsius above pre-industrial levels. Such a thing is very close to the 1.5C threshold for extreme impacts explained in a major 2016 report by the IPCC. Also, the Paris Agreement has urged nations to cap global warming at “well below” 2C, and 1.5C if possible.
So far, the planet has warmed on average by 1C, enough to raise the intensity of deadly heatwaves, tropical storms, and droughts made more unfavorable by rising seas.
Furthermore, climate change influenced by greenhouse gas emissions from burning fossil fuels increased in recent decades. 19 of the 20 last years are reported to be the warmest since precise readings emerged in the late 19th century. According to the EU data, since the late 1970s, the global thermometer has increased by 0.2C every decade.
However, temperatures last month were “exceptionally high” over northern Siberia, which has warm weather for months now. September was also brutal in the Middle East, with new high temperatures reported in Jordan, Israel, and Turkey.
About Fire and Ice
Parts of Tibet and North Africa were also getting warmer. Maximum daytime values reported reached 49C in LA County early this month. And across California, five of the state’s largest wildfires in history were still burning at the end of September.
As for the Arctic sea ice, this shrank to its second-lowest extent last month, too, getting below 4 million square kilometers. The Arctic ice cap also floats on ocean water around the North Pole. Such a thing doesn’t influence the sea level rise directly when it melts, but it does raise global warming.
