Q. 168 & If the global albedo is increased from 0.3 to 0.4 , the global radiative equilibrium \\
temperature (in $\mathrm{K}$ ) would decrease by \\
(consider no greenhouse effect, solar constant $=1360 \mathrm{~W} \mathrm{~m}{ }^{-2}$ and Stefan- \\
Boltzmann constant $=5.67 \times 10^{-8} \mathrm{~W} \mathrm{~m}^{-2} \mathrm{~K}^{-4}$, rounded off to one decimal place).
