10 Φεβ 2020 · When the concentration of carbon dioxide in the air outside a plant leaf goes up, it can be taken up faster, super-charging the rate of photosynthesis.
The atmosphere is vital for all life on the planet, not only humans, and for reasons other than supplying gases needed for respiration and photosynthesis. Winds also transport water into the interiors of large areas of land, which would otherwise rapidly become parched desert.
Global Climate Change Explorer: Atmosphere. Earth’s atmosphere does many important tasks for us—it shields us from UV radiation, generates weather, and is the very air we breathe. But its ability to keep our planet warm is what makes the atmosphere so important to climate change. Credit: NASA.
30 Οκτ 2023 · It’s the extra CO 2 in the air today—from human activities like burning fossil fuels—that has boosted the rate of photosynthesis and let plants take up more carbon, which they use to grow faster and use water more efficiently.
Carbon dioxide in the atmosphere warms the planet, causing climate change. Human activities have raised the atmosphere’s carbon dioxide content by 50% in less than 200 years.
8 Ιαν 2024 · “The short answer,” Des Marais says, “is that most plants will grow faster and bigger with extra atmospheric CO 2 —all else being equal.” However, plant growth is too complex for a one-size-fits-all law like “more CO 2 is better.”
Carbon flows between the atmosphere, land, and ocean in a cycle that encompasses nearly all life and sets the thermostat for Earth's climate. By burning fossil fuels, people are changing the carbon cycle with far-reaching consequences.
