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 to 1.5°C. Most countries lose additional net revenue with the additional warming and the additional loss is greater than the loss they experience with the initial warming.
