The last time the Earth had a month of normal temperatures, compared to the 20th century, was in. Lebron James was a crawling baby, a little over a month. Barack Obama was 24 years old. Billie Eilish would not be born in another 16 years.
420 consecutive months have passed since the Earth, in general, experienced a year of normal temperatures of the twentieth century, according to data collected and analyzed by the US National Oceanic and Atmospheric Administration (NOAA). UU.
On Thursday, the agency published data showing that December 2019 was the second hottest December in 140 years of modern record keeping, and that the last six of December were the warmest six in recorded history.
The long-term trend is clear, beyond the cultural milestone of 420 consecutive months of above-average temperatures:
A routine argument of denial of climate science, although intentionally ignorant and increasingly pathetic, is that cold or low records were also broken in 2019. Of course, winter still comes and the daily climate will always fluctuate. But a critical point is with the background warming added, high temperature records are rapidly surpassing low temperature records. It is not even close.
In mid December, 364 The all-time high temperatures were set in 2019, compared to just 70 minimums of all time.
“As the weather changes to a warmer climate, we expect to see more extreme warm temperatures,” Ahira Sánchez-Lugo, a climatologist with the National Oceanic and Atmospheric Administration, told Mashable in December. “That is what we are seeing and that is what the data shows.”
Meanwhile, the Earth’s carbon dioxide atmospheric emissions, a powerful greenhouse gas, are now skyrocketing. CO2 levels have not been so high in at least 800,000 years, although millions of years are more likely. In addition, carbon levels are now rising at rates that are unprecedented in both the geological and historical records.
These rapid and robust changes are unequivocally heating the Earth and continuously breaking the daily, monthly and annual records. “As we have shown in recent work, the record hot streaks we have seen in recent years simply cannot be explained without taking into account the profound impact we are having on the planet through the burning of fossil fuels and the resulting increase in atmospheric greenhouse gases concentrations, “climate scientist Michael Mann, director of the Earth System Science Center at Penn State University, told Mashable after Earth experienced the hottest month of June 2019.
Earth will soon reach another 420 milestone, perhaps in 2021. Global atmospheric carbon dioxide concentrations almost reached 415 parts per million, or ppm, in 2019.
But with carbon emissions constantly increasing, 420 ppm is a safe bet.
