Trees play an important role in the carbon cycle by absorbing carbon dioxide from the atmosphere during photosynthesis and storing it in their biomass. Now, imagine Grandpa owns a large piece of land and decides to clear all the trees on the land to create space for a new farm. Considering the role trees play in regulating atmospheric carbon dioxide, what is the most likely impact of this action on climate change?

• It decreases the amount of carbon dioxide in the atmosphere

• It increases the Earth's albedo

• It increases the amount of carbon dioxide in the atmosphere

• It has no significant impact on climate change
