Question

how much longer is the duration in the atmosphere for nitrous oxide as compared to methane?the duration in the atmosphere for nitrous oxide is 121 years and methane is 12 years3. which of these gases is most likely to have the greatest warming effect on earths climate? what other factors might need to be considered to form a valid conclusion?water vapor is most likely to have the greatest warming effect on earths climate. it acts, powerful, self reinforcing greenhouse gas feedback.4. if you could eliminate one gas from the atmosphere to reduce the greenhouse effect, which one would it be and why?i would eliminate carbon dioxide, and because it would be the most effective action to reduce a long-term greenhouse effect.natalie hedden15 hours agonitrous oxide is most likely to have the greatest warming effect because it has a higher gwp and stays in the atmosphere longer. to know if this is true for earth as a whole, you would need to know how much nitrous oxide and methane are added to the atmosphere each year.natalie hedden15 hours agocarbon dioxide is what we breathe out naturally. are you saying the excess of co2 that is not naturally produced?

Explanation:

Step1: Calculate time difference

Subtract methane's atmospheric lifetime from nitrous oxide's:
$121 - 12 = 109$

for Question 3:
Nitrous oxide has a much higher Global Warming Potential (GWP) than water vapor and stays in the atmosphere far longer. To form a valid conclusion, we must also consider annual emission rates of each gas, their atmospheric concentrations, and how they interact with other greenhouse gases and climate feedback loops.

for Question 4:
Carbon dioxide is the primary driver of long-term anthropogenic climate change due to its extremely high atmospheric concentration, long lifetime (centuries to millennia), and the massive volume of human-caused emissions. Eliminating excess anthropogenic CO₂ would address the largest cumulative contributor to the greenhouse effect.

Answer:

for Question 1:
Nitrous oxide remains in the atmosphere 109 years longer than methane.
