Because the COVID-19 pandemic caused a massive economic slowdown, experts had hoped that the decline in transportation and manufacturing might slow greenhouse gas emissions at least a little.
Unfortunately, a new report by the National Oceanic and Atmospheric Administration (NOAA) reveals that one of the major gases behind climate change has reached its highest level in 3.6 million years.
The NOAA reports that the average amount of carbon dioxide (CO2) in the atmosphere was 412.5 parts per million (ppm) in 2020, an increase by 2.6 ppm through the course of the year.
Climate scientists generally agree that in order for life on Earth to be minimally interrupted, Earth’s carbon dioxide levels should remain under 350 parts per million. Yet since NOAA begin recording atmospheric composition data in 1960, there has not been a year in which carbon dioxide levels in the atmosphere did not increase.
Likewise, in 2020, overall carbon dioxide emissions increased at the fifth-highest rate in the 63 years that NOAA has been recording. It was only surpassed by the rates of increase in 1987, 1998, 2015 and 2016.
A senior scientist at NOAA’s Global Monitoring Laboratory, Pieter Tans, said that if there had not been an economic slowdown, it would have been the highest increase on record. As things current stand, the carbon dioxide levels in the atmosphere are at a point comparable to the Mid-Pliocene Warm Period, when the temperature was 7 degrees hotter and the sea level was roughly 78 feet higher than today.
Another organization, Scripps Institution of Oceanography at UC San Diego, released similar results on Wednesday, announcing that carbon dioxide in the atmosphere was 417.4 ppm at their monitoring station in Hawaii.
The NOAA also reported a “significant jump” in the atmospheric burden of methane in 2020, with the annual amount increasing by 14.7 parts per billion (ppb) in 2020. Not only is this the biggest jump since methane levels began to be systematically measured in 1983, but it is also troubling because of how effective methane is at trapping heat. Although there is much less methane than carbon dioxide in our atmosphere, it is 28 times more potent at trapping heat over the course of a century.
Still, the COVID-19 lockdowns had a minor effect on emissions.
“The estimates vary among the different groups doing these sorts of calculations, but the consensus seems to be about a 7% decrease [in greenhouse gas emissions] relative to 2019 levels,” Dr. Michael E. Mann, a distinguished professor of atmospheric science at Penn State University, wrote to Salon in December.
If climate change is not halted and/or reversed in the near future, experts agree that there will be serious and negative repercussions for all life on Earth, including humans. There will be an increase in extreme weather events like hurricanes and blizzards, an increase in the amount of wildfires and a reduction in the amount of land that can be used to produce food. All of this will lead to fierce competition for resources and mass population displacements, even as an increasing amount of the world’s surface either too hot or too dry to be inhabitable.
President Joe Biden has said that he will prioritize fighting climate change in his presidency. Shortly after taking office, he said in a statement that “environmental justice will be at the center of all we do.”
Help us Prepare for Trump’s Day One
Trump is busy getting ready for Day One of his presidency – but so is Truthout.
Trump has made it no secret that he is planning a demolition-style attack on both specific communities and democracy as a whole, beginning on his first day in office. With over 25 executive orders and directives queued up for January 20, he’s promised to “launch the largest deportation program in American history,” roll back anti-discrimination protections for transgender students, and implement a “drill, drill, drill” approach to ramp up oil and gas extraction.
Organizations like Truthout are also being threatened by legislation like HR 9495, the “nonprofit killer bill” that would allow the Treasury Secretary to declare any nonprofit a “terrorist-supporting organization” and strip its tax-exempt status without due process. Progressive media like Truthout that has courageously focused on reporting on Israel’s genocide in Gaza are in the bill’s crosshairs.
As journalists, we have a responsibility to look at hard realities and communicate them to you. We hope that you, like us, can use this information to prepare for what’s to come.
And if you feel uncertain about what to do in the face of a second Trump administration, we invite you to be an indispensable part of Truthout’s preparations.
In addition to covering the widespread onslaught of draconian policy, we’re shoring up our resources for what might come next for progressive media: bad-faith lawsuits from far-right ghouls, legislation that seeks to strip us of our ability to receive tax-deductible donations, and further throttling of our reach on social media platforms owned by Trump’s sycophants.
We’re preparing right now for Trump’s Day One: building a brave coalition of movement media; reaching out to the activists, academics, and thinkers we trust to shine a light on the inner workings of authoritarianism; and planning to use journalism as a tool to equip movements to protect the people, lands, and principles most vulnerable to Trump’s destruction.
We urgently need your help to prepare. As you know, our December fundraiser is our most important of the year and will determine the scale of work we’ll be able to do in 2025. We’ve set two goals: to raise $104,000 in one-time donations and to add 1340 new monthly donors by midnight on December 31.
Today, we’re asking all of our readers to start a monthly donation or make a one-time donation – as a commitment to stand with us on day one of Trump’s presidency, and every day after that, as we produce journalism that combats authoritarianism, censorship, injustice, and misinformation. You’re an essential part of our future – please join the movement by making a tax-deductible donation today.
If you have the means to make a substantial gift, please dig deep during this critical time!
With gratitude and resolve,
Maya, Negin, Saima, and Ziggy
