Climate change has been a worrying issue that we face for recent years. Some records have been broken, marking the warning of how crucial climate change to be overcome. NASA and America’s National Oceanic and Atmospheric Administration reported that 2010-2019 was the hottest decade since the 1800s. In 2019, the carbon emission reached a new record. Then, what records that we hit in 2021? Here are 5 climate change records we surpassed in 2021.
- The hottest years ever recorded. Between 2015 and 2021, the last seven years have been the warmest on record. The average global temperature in 2021 was roughly 1.11 degrees Celsius higher than the average global temperature between 1850 and 1900.
- A high rise of sea level. The sea level rose 4.55mm a year on average between 2013 and 2021. Moreover, some places like the South-west Pacific, the South-west Indian Ocean and the South Atlantic experienced the rising of sea levels faster than the global average.
- Wider ozone hole over the Antarctic. In 2021, the ozone hole of the Antarctic grew more than 70% since 1979. The cold conditions in the stratosphere and a strong polar vortex also took part in worsening the ozone condition.
- The first rain at Greenland’s highest top. Rain fell for the first time at the top of Greenland’s ice sheet. The air temperature also remained above freezing degrees for 9 hours.
- Highest-ever temperature since the 1930s. The temperature in Death Valley, California touched 54.4 degrees Celsius in 2021, while Kairouan in Tunisia reached 50.3 degrees Celsius, 47.4 degrees Celsius in Montoro, Spain and 49.1 degrees Celsius in between Turkey and Syria. This high temperature led to heat waves that occurred in several regions in this world.
