NASA SATELLITES DISCOVER LOWER HUMAN CO2 EMISSIONS FOR THE FIRST TIME
The COVID-19 pandemic is having an impact on human activities, such as energy use and CO2 emissions. For the first time during the Covid-19 outbreak, a team of NASA scientists identified regional changes in atmospheric carbon dioxide (CO2) linked to human activities. According to reports, the scientists used a combination of NASA satellites and atmospheric models to assess CO2 emissions during the outbreak from space, including data from NASA's Orbiting Carbon Observatory-2 (OCO-2). Previous research looked examined the effects of early pandemic lockdowns and found that global CO2 levels declined marginally in 2020. By combining OCO-2's high-resolution data with modelling and data analysis tools from NASA's Goddard Earth Observing System, the team was able to determine which monthly changes were due to human activities and which were due to natural causes on a regional scale (GEOS). According to the team's research, human-caused CO2 concentrations in the Northern Hemisp...
