Statements A, B and D are correct because they describe well-known impacts of global warming on coasts, agriculture, water and cryosphere. However, statement C is incorrect as research indicates that global warming can influence the frequency and intensity of certain extreme weather events such as heatwaves and heavy rainfall. Since option B treats C as correct along with the other statements, it cannot logically be the correct answer. The correct combination must therefore include only A, B and D, excluding C.
Option A:
Option A is correct because it gathers together A, B and D, all of which are supported by climate science, while omitting C. It recognises coastal risks, shifts in agriculture and water stress and the implications of glacier melt. By excluding the wrong statement, it matches the question requirement.
Option B:
Option B is incorrect as it treats all four statements as correct. It incorrectly endorses C, which denies any influence of global warming on extreme events, contradicting current scientific assessments. Consequently, this option is invalid.
Option C:
Option C is incorrect because it includes C alongside B and D and leaves out A. Apart from omitting a correct statement about sea-level rise, it wrongly accepts C, thereby misrepresenting the climate change–extreme weather link.
Option D:
Option D is incorrect as it includes A, C and D and omits B. It still retains the false statement C and thus fails to present an accurate set of correct statements about global warming impacts.
