NASA scientists spot first-ever reduced human CO2 emissions

For the first time in NASA’s history, a group of scientists found a change in the atmospheric carbon dioxide related to the emissions by human activities and it was spotted during the Covid-19 pandemic times. NASA scientists used satellites and atmospheric modeling, the team thoroughly studied the measured drops in CO2 emissions during the pandemic from space.

Data from NASA’s Orbiting Carbon Observatory-2 has also been used to study the change in atmospheric carbon dioxide. Previous research has examined the consequences of lockdowns at the beginning of the Pandemic and found that CO2 levels around the world lowered by 2020.

After analyzing the change, the scientists came to the conclusion that the monthly changes are due to human activity and at the local level natural causes. In May 2020, the northern hemisphere showed a drop in human-generated growth in CO2 concentrations. However, during the summertime, it rose again in line with global emissions.

The team, after analyzing the changes said, the use of technologies and modeling helped to detect the changes in each region and the regional effects of climate change. The team used satellite techniques which helped to get fast actionable information about how human and natural emissions are involved. 

It was all because of the pandemic period which pushed people to stay indoors during the outbreak. At that time, cars and other means of transportation on the road were reduced, and the number of greenhouse gases and pollutants emitted into the atmosphere dropped sharply.

NASA Atmosphere on its official Twitter page noted, “NASA scientists tracked short-term, regional changes in emissions of the greenhouse gas carbon dioxide during the Covid-19 pandemic, narrowing down which monthly changes were caused by human activity and which weren’t.”
