How does CO2 in the atmosphere affect temperature?

When there’s more CO2 in the atmosphere, it makes the atmosphere warmer by trapping heat. Since humans are adding more CO2 to the atmosphere, that helps explain why temperatures are increasing around the world.

What is the result of heat being trapped in the atmosphere from increased CO2 levels?

Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating. At the same time global average temperatures are rising as a result of heat trapped by the additional CO2 and increased water vapor concentration.

Can CO2 cause climate change?

Scientists say that if CO2 doubles, it could raise the average global temperature of the Earth between two and five degrees Celsius. We are already increasing the amount of energy that bounces back to the Earth. Because of the greenhouse effect, this is causing global warming with its many destructive impacts.

How does CO2 get into the atmosphere?

Carbon dioxide (CO2): Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and other biological materials, and also as a result of certain chemical reactions (e.g., manufacture of cement).

Why does CO2 stay in the atmosphere?

Some of the excess carbon dioxide is absorbed quickly (for example, by the ocean surface), but some will remain in the atmosphere for thousands of years, due in part to the very slow process by which carbon is transferred to ocean sediments.

How does carbon dioxide absorb heat?

Molecules of carbon dioxide (CO2) can absorb energy from infrared (IR) radiation. The energy from the photon causes the CO2 molecule to vibrate. Some time later, the molecule gives up this extra energy by emitting another infrared photon.

How does CO2 cause global warming a level chemistry?

Extra carbon dioxide in the atmosphere increases the greenhouse effect. More thermal energy is trapped by the atmosphere, causing the planet to become warmer than it would be naturally. This increase in the Earth’s temperature is called global warming .

What are the effects of CO2?

Exposure to CO2 can produce a variety of health effects. These may include headaches, dizziness, restlessness, a tingling or pins or needles feeling, difficulty breathing, sweating, tiredness, increased heart rate, elevated blood pressure, coma, asphyxia, and convulsions.

How does CO2 get out of the atmosphere?

Carbon dioxide can be removed from the atmosphere as air passes through a big air filter and then stored deep underground. This technology already exists and is being used on a small scale.
