Adding carbon fertilization reduces but does not offset the damage with the 3°C scenario. Warming of 3°C with carbon fertilization causes damage of US$84 billion yr1. Asia as a whole suffers a 12% loss of aggregate net revenue. Compared to current temperatures, half the countries gain net revenue and half the countries lose net revenue. However, looking at just the additional warming from 1.5 to 3.0°C, only
Afghanistan, North Korea, Japan, and Tajikistan gain in net revenue and the gain is much smaller than what they gained from the initial warming from current temperatures
to1.5°C. Most countries lose additional net
revenue with the additional warming and the addition
al loss is greater than the loss they experience with the
initial warming.
