Lockdown has improved air quality but Carbon Dioxide is still at its highest-ever level: Study
New Delhi | Jagran Lifestyle Desk: The lockdowns across the world to control the spread COVID-19 pandemic, on the brighter side, have improved the air quality quite significantly that the world's most polluted capitals and millions-huge cities hadn't breathed this cleaner until the April-May months of 2020. However, a recent assessment has shown that despite the lockdown, due to phenomenally considerable heat-trapping, the Carbon Dioxide content is recording its highest-ever levels in our atmosphere.
According to the data, collected at the Mauna Loa observatory in the US, and recently released by California's Scripps Institution of Oceanography and the National Oceanic and Atmospheric Administration (NOAA), the concentration of Carbon Dioxide in the atmosphere was recorded as 417.2 (ppm) parts per million in May, which is higher than the peak of 414.8ppm recorded in 2019.
“The highest monthly mean CO2 value of the year occurs in May, just before plants start to remove large amounts of CO2 from the atmosphere during the northern hemisphere growing season. In the northern fall, winter, and early spring, plants and soils give off CO2, causing levels to rise through May,” the research was quoted as stating.
"These are measurements of the real atmosphere. They do not depend on any models, but they help us verify climate model projections, which if anything, have underestimated the rapid pace of climate change being observed," Pieter Tans, a senior scientist with NOAA’s Global Monitoring Division told the media, implying that even though the air quality has improved, the Climate change patterns continue to remain unhinged from its pre-COVID times' trajectory.
The Carbon Dioxide levels in the atmosphere rose to above 400ppm in 2014 and have stayed above that mark since, reported News 18.
