Scientists at the National Oceanic and Atmospheric Administration reported that atmospheric greenhouse gas concentrations are the highest concentration ever recorded. CO2 concentrations in the atmosphere reached 412.5 parts per million in 2020–2.5 parts per million higher than in 2019– despite a brief decline in carbon emissions caused by the COVID-19 pandemic.
Why This Matters: The planet has reached a climate tipping point. Each of the last four decades was successively warmer than any decade that preceded it since 1850, and in 2019, atmospheric CO2 concentrations were higher than at any time in 2 million years.
As emissions continue to increase, targets aiming to limit the spread of global warming — like the Paris Agreement— look increasingly out of reach. Additionally, a recent report found that the world fell short of a “green recovery” from the pandemic and failed to take advantage of the emissions advantage gained by a year in quarantine. As the COP26 climate conference in Glasgow rapidly approaches, the world’s nations will need to come together to take unprecedented climate action on an ever-tightening deadline.
“It’s a record that keeps playing over and over again,”said Jessica Blunden, a NOAA climate scientist. “Things are getting more and more intense every year because emissions are happening every year.” The “State of the Climate in 2020” assessment was published in the Bulletin of the American Meteorological Society and results from 530 scientists from 66 countries. They found that despite a 6 to 7 percent dip in emissions in 2020, the two gigatons of carbon dioxide saved were not enough to have a lasting positive effect.
Scientists also found a worrying spike in methane concentrations in the atmosphere, rising to the highest levels in 1,000 years. Scientists believe this spike may be caused by increased microbial activity in human-made environments like landfills and farms and natural environments like wetlands. They worry that because microbial activity increases in warming temperatures, these environments have entered a dangerously emitting climate feedback loop.
Last year didn’t only break records for greenhouses gas emissions in the atmosphere. Scientists from the National Oceanic and Atmospheric Administration (NOAA) also suggest that the amount of carbon from fossil fuel emissions in the oceans in 2020 was the highest it’s been in 39 years and 30% higher than the average amount measured from 1999-2019. 2020 was also the ninth year in a row that global sea levels reached record highs. Meanwhile, the global surface temperature in 2020 was also among the three highest ever recorded in data representing the last 200 years.
This week is Climate Week NYC, an annual event hosted by The Climate Group and the United Nations, in partnership with the COP26 and the City of New York. For one week, from September 20-26, experts will be hosting panels and conversations about all things climate, and you can follow along at home via Facebook […]
By Natasha Lasky, ODP Staff Writer A new study titled, Flying blind: The glaring absence of climate risks in financial reporting, from Carbon Tracker and the Climate Accounting Project (CAP) showed that 107 global businesses that work in high-emissions fields like oil and gas firms, construction, car manufacturers, and aviation businesses, have not been transparent […]
By Amy Lupica, ODP Daily Editor New research published in Proceedings of the National Academy of Sciences suggests that without the world’s complex ecosystems and wildlife, human activity would have already pushed the global average temperature past 1.5 degrees Celsius. Findings from scientists working with Conservation International (CI) spotlight the role forests, oceans, and more […]
