We would expect the temperature to increase as CO2 levels rise. And in fact global warming has been directly linked to anthropogenic releases of CO2 gas.

Studies of this effect assume CO2 increases would NOT have this impact on the climate. This is known as the "null hypothesis." Careful analysis subsequently revealed the null hypothesis must be rejected, ergo human activity IS increasing earth's temperature.

Which gas traps heat in the atmosphere of venus?

Carbon dioxide is the main gas that traps heat in the atmosphere of Venus through a greenhouse effect, leading to extremely high surface temperatures.


What gas traps the most heat in Venus' atmosphere?

Carbon dioxide (CO2) is the primary greenhouse gas in Venus' atmosphere that traps the most heat. It accounts for over 96% of the atmosphere and contributes significantly to the planet's extreme temperatures.


What removed carbon dioxide from the atmosphere acting as a carbon sink?

Other than photosynthesis, the formation of carbonates in the ocean traps carbon from the atmosphere.


What and why does carbon dioxide rises with?

Carbon dioxide rises in the atmosphere as a result of human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release excessive amounts of carbon dioxide, a greenhouse gas, which traps heat in the Earth's atmosphere and contributes to global warming and climate change.


When carbon reacts with oxygen to form carbon dioxide carbon dioxide is?

When carbon reacts with oxygen to form carbon dioxide, carbon dioxide is the product of the reaction.


What planet has a very dense atmosphere of carbon dioxide?

Venus has a very dense atmosphere composed mostly of carbon dioxide. This thick atmosphere traps heat, making Venus the hottest planet in our solar system.


What happens when carbon dioxide levels decrease in the atmosphere?

When carbon dioxide levels decrease in the atmosphere, it can lead to a cooling effect. This is because carbon dioxide is a greenhouse gas that traps heat in the atmosphere. A decrease in carbon dioxide levels could potentially impact climate patterns, biodiversity, and ocean acidity.


Which gas traps heat on Venus gas solar energy?

Venus has a very thick carbon dioxide atmosphere, which traps the heat from the sun.


What process removes carbon dioxide from the atmosphere acting as a carbon sink?

Photosynthesis is a process that removes carbon dioxide from the atmosphere, acting as a carbon sink. During photosynthesis, plants absorb carbon dioxide and convert it into oxygen and glucose, which is then stored as biomass. This helps to reduce the amount of carbon dioxide in the atmosphere, balancing the carbon cycle.
