It turns out, 2021 wasn't the hottest on record for the planet, nor were the most records set, nor was Arctic sea ice at its lowest level, or rainfall at its highest. But 2021 was the 7th year of a 7-year run of the hottest years ever:
In 2021, global temperatures were between 1.1 and 1.2 degrees Celsius (2.2 degrees Fahrenheit) above the preindustrial average, according to new data from NASA, the National Oceanic and Atmospheric Administration and Berkeley Earth.
Despite a La Niña weather pattern in the Pacific Ocean, which tends to cool the planet, 2021 was roughly tied for sixth-hottest year ever observed, scientists say. All of the seven hottest years on record have happened in the last seven years.
The year 2021 was the seventh in a row in which global temperatures were more than 1 degree Celsius above the preindustrial average. It’s unlikely anyone alive will see the world’s temperature drop below that 1-degree benchmark again.
The United States endured at least 20 weather disasters costing $1 billion or more last year, the second most on record, NOAA announced this week. Hurricanes, wildfires, tornadoes and floods — almost all of them made worse by climate change — killed at least 688 people and caused at least $145 billion in damage.
I meant to post about this yesterday when I read it. After all, we stand a pretty good chance of having one of the 8 hottest years on record this year.
