Why did climate cool during the past 40 million years?
What will be an ideal response?
One theory is that climate cooled as a result of the collision of the Indian and Eurasian plates. This collision caused the uplift that led to the formation of the Himalayan Mountains and the Tibetan Plateau. This created both fresh weathering surfaces and high seasonal rainfall, allowing for high weathering rates. The high weathering rates led to the drawdown of CO2 as silicate minerals were weathered away. The decrease in CO2 levels lessened the greenhouse effect, cooling the Earth.
