Atmospheric CO2 levels have reached 400 ppm and global warming is no longer a question—it is a fact. Explain three consequences of this trend in climate change?
What will be an ideal response?
Answer: 1) Sea level rise due to melting Arctic and Antarctic sea ice and the melting of glaciers and continental ice sheets. 2) Changes in precipitation patterns—wet areas will get wetter, dry areas will get drier. This not only impacts food production but many levels of society. 3) Extreme weather conditions—severe winter storms and severe drought.
