Question

question 10 (1 point)
according to the ipcc, if nothing is done to curb intensive fossil fuel emissions,
there will be a likely rise in mean temperatures of the order of

a) $0.5^circ$c to $1.4^circ$c.

b) $10.3^circ$c to $12^circ$c.

c) the normal fluctuation within its natural cycle.

d) $2.4^circ$c to $6.4^circ$c.

Explanation:

The Intergovernmental Panel on Climate Change (IPCC) has warned that if no action is taken to reduce fossil fuel emissions, the mean temperature rise will be significant. Option a is too low as it represents a smaller - scale temperature change that might be associated with some natural or less - intense anthropogenic effects. Option b is extremely high and not in line with the IPCC's more conservative yet still concerning projections. Option c is incorrect because the rise due to unabated fossil fuel emissions is not a normal natural - cycle fluctuation. The IPCC's projections for a likely rise in mean temperatures in a business - as - usual (unabated fossil fuel emissions) scenario fall in the range of \(2.4^{\circ}C\) to \(6.4^{\circ}C\).

Answer:

d) \(2.4^{\circ}C\) to \(6.4^{\circ}C\)
