New Delhi: The National Aeronautics and Space Administration (NASA) has captured some shocking visuals showing how human activity is increasing the atmospheric concentration of carbon dioxide. For several centuries now, human activity has been emitting carbon dioxide into the atmosphere. It is also a known fact that carbon dioxide affects the radiation of heat back into space and contributes to global warming.
NASA has shared three separate videos covering various parts of the world. In each of these videos, the carbon emission from different parts of our world is shown. The videos further highlight carbon emissions, and carbon absorption due to trees and oceans.
According to NASA, this visualisation shows the CO2 being added to Earth’s atmosphere over the course of the year 2021, split into four major contributors: fossil fuels in orange, burning biomass in red, land ecosystems in green, and the ocean in blue.
Here are some of the important takeaways from the videos:
- Carbon emissions due to the burning of fossil fuels is represented by colour orange.
- Red represents burning of biomass.
- Green denotes land ecosystems and blue stands for oceans.
- Blue dots show where carbon dioxide is being absorbed by oceans
- Green dots are representing CO2 absorption by trees.
- The concentration of carbon emissions in North America, particularly in the Northeastern part of the US. These are the pollution hotspots.
According to Climate.gov, “Without carbon dioxide, Earth’s natural greenhouse effect would be too weak to keep the average global surface temperature above freezing. By adding more carbon dioxide to the atmosphere, people are supercharging the natural greenhouse effect, causing global temperatures to rise.”
“New computer modeling techniques in NASA’s Global Modeling and Assimilation Office allow us to dissect our atmosphere and understand some of the major contributors to this runaway insulator,” says NASA in the blog post.
