We’re breaking carbon dioxide records despite lockdown.

The world came to a halt in parts of the last year. But carbon dioxide continues to set records. Atmospheric concentrations of greenhouse gases peaked last month. Scientists said MondayIt hit a new monthly record high at 419 parts per million. That’s the highest average level in millions of years. Cool!

The new averages come from readings from the Mauna Loa Atmospheric Base Observatory, a research station run by the National Atmospheric and Oceanic Administration and the Scripps Institution of Oceanography, where scientists have been. Carbon Dioxide Concentration Record Since 1958, when carbon dioxide was at 316 ppmAnd those records have flipped up very quickly recently. The first time we passed the 400 ppm mark in 2013, so the rate at which we reach 419 ppm is quite alarming. Carbon dioxide levels have Exceeded the daily reading of 420 ppm twice this year.. (annual average Most likely in May; Plants absorb a lot of carbon dioxide during the summer growing season. as plants and soil begin emitting carbon dioxide in the fall and winter).

“We are adding about 40 billion metric tons of CO2 pollution to the atmosphere per year,” Pieter Tans, senior scientist at NOAA’s Global Monitoring Laboratory, said in a press release. “That’s the carbon mountain that we dig out of the earth, burn and release into the atmosphere in the form of CO2, year after year if we want to avoid the cataclysm of climate change. The top priority must be to reduce CO2 pollution to zero as quickly as possible.”

During the 63-year recording at the observatory, fossils, ice cores and Other geological records Help scientists determine the Earth’s atmosphere before we start collecting data directly. Carbon dioxide in the atmosphere is about the same level as that it was in the Pliocene periodAbout 4 million years ago, when global temperatures were about 14.4 degrees Fahrenheit (8 degrees Celsius), warmer than it is now. The Arctic has no ice in the summer. and may be full of trees and green plants and woolly mammoths, saber-toothed tigers, giant sloths, and armadillos roaming around.

Scientists recorded average monthly carbon dioxide of 417 ppm in May 2020, and the year-on-year increase was slightly less than the year before. What’s really worrying is that even though most of the world has paused due to the pandemic. But carbon emissions appear to be back to normal. Scientists say the increase in carbon dioxide in the first five months of 2021 is 2.3 parts per million. It is estimated to increase on average annually between 2010 and 2019. The increase is despite a 4% drop in global energy consumption and a 5.8 percent drop in emissions, the International Energy Agency said in a statement. latest reportThat was the biggest drop in emissions on record for 2020 and is estimated to be “equivalent to removing all EU emissions from the global total,” the IEA said. to Follow up on carbon dioxide dipping.But now it looks like we’re heading in the wrong direction despite the recent weather pledges President Joe Biden and other world leaders to control emissions

“As long as we keep emitting carbon dioxide,” Tans Tell Axios. “And that’s what we saw. Even if we can suspend net emissions.”
