¥Assume that the Earth is warming.
¥ - Warming leads to more evaporation
from oceans, which increases
water vapor in atmosphere.
¥ -More water vapor increases
absorption of IR, which
strengthens the greenhouse effect.
¥ -This raises temperatures further,
which leads to more
evaporation, more water vapor, warmingÉ
