NASA unveils a computer animation showing what Earth would look like if we could see CO2. The visuals uncover the gas's major sources, cycles, and impacts on global warming.
This is undoubtedly one of the weirdest animations of Earth I have seen. NASA’s Global Modeling and Assimilation Office unveils a computer animation portraying our planet as if we could visually detect carbon dioxide (CO2), transforming Earth into an uncanny spectacle with gas cycles ebbing and flowing.
NASA presented three animations, all illustrating CO2 levels throughout 2021, with major contributors including fossil fuels, biomass burning, land ecosystems, and oceans. These videos unravel Earth’s interaction with this omnipresent gas.
What Earth Would Look If You Could See Carbon Dioxide Emissions
In the animation covering the Americas, the cycle of plant absorption and release of CO2 becomes apparent. Particularly intense emissions dot the US northeastern seaboard due to fossil fuel burning. A cyclical rise and fall of the gas can also be observed over the Amazon rainforest.
The animations highlight Asia’s vast fossil fuel emissions, notably over China, contrasted with Australia’s higher gas absorption and lower emissions, largely due to its smaller population. Another view exposes Europe’s reliance on fossil fuels and Africa’s crop-clearing fires, illustrating the greenhouse gas’s atmospheric cycle.
The Universal Presence of Carbon Dioxide
CO2 is not Earth-exclusive; its presence extends to Mars and Venus. The James Webb Space Telescope recently reported CO2 traces on an exoplanet, proving its universal role in planetary atmospheres. CO2 is essential to our planet’s climate. It traps sunlight to maintain Earth’s habitability. However, excessive amounts, along with other greenhouse gases like methane, intensify global warming, leading to dire consequences.
Carbon Dioxide: A Complex Part of Climate Change
Both natural and anthropogenic sources contribute to Earth’s CO2 levels. Natural sources largely comprise oceans, animal and plant respiration, organic matter decomposition, forest fires, and volcanic eruptions. Simultaneously, power generation, chemical production, agricultural practices, and transportation make up most human-induced sources.
Carbon dioxide undergoes a natural cycle of exchange among the air, ground, oceans, plants, and living beings. However, modern activities have upset this balance, causing CO2 levels to spike by 50% in under two centuries, accelerating global warming.
Understanding the Temperature Rise
Historically, Earth’s temperature has increased by about 0.08°C (0.14°F) each decade. This warming, driven largely by CO2 increase, has led to a 2-degree rise over a century, significantly impacting weather patterns and environmental processes.
Animations and maps of CO2 sources, sinks, and cycles offer a visual aid to comprehend the atmospheric changes over time. They are a stark reminder of our planet’s evolving climate narrative.
