NASA has released a mew high-resolution model that visualises the movement of carbon dioxide across the globe, including over India, offering unprecedented insights into the dynamics of this crucial greenhouse gas.

The model, created by NASA's Scientific Visualisation Studio using the Goddard Earth Observing System (GEOS), provides a detailed look at CO2 concentrations from January to March 2020.

The map clearly shows that in China, the United States, and India, most emissions originated from power plants, industrial facilities, and vehicles.

In contrast, Africa and South America's emissions were largely due to fires, including those related to land management, agricultural burns, and deforestation.

As per the NASA, the concentration of CO2 in the atmosphere has increased from about 278 parts per million in 1750 to 427 parts per million in May 2024.

This new model provides valuable data for understanding and potentially mitigating the impact of CO2 emissions on our planet's climate.

Why it matters?

All this carbon dioxide isn’t harmful to air quality. In fact, we need some carbon dioxide to keep the planet warm enough for life to exist.

But when too much CO2 is pumped into the atmosphere, the Earth warms too much and too fast. That’s what has been happening for at least the past half century. The concentration of carbon dioxide in the atmosphere increased from approximately 278 parts per million in 1750, the beginning of the industrial era, to 427 parts per million in May 2024.
