Gce Model Questions Vol1 2017 Geography Question 42
Practice objective / multiple choice question 42 from the 2017 Gce Model Questions Vol1 Geography examination.
Using the simplified radiative‑forcing formula \(\Delta F = 5.35 \ln\left(\dfrac{C}{C_{0}}\right)\) (where \(C\) is the atmospheric CO₂ concentration in ppm and \(C_{0}=280\) ppm), and a climate‑sensitivity factor of \(0.8^{\circ}\text{C}\) per W m⁻², calculate the temperature increase for (i) the present concentration \(C_{1}=415\) ppm and (ii) a future concentration \(C_{2}=550\) ppm. Then give the difference \(\Delta T_{2}-\Delta T_{1}\) (in °C) between the two scenarios, rounded to two decimal places.
