The position of earth's continents has shifted dramatically over its history. imagine that all of earth's land mass was bunched together with approximately equal areas above and below the equator. assume that seasonal patterns of growth and respiration are otherwise similar, with the northern hemisphere's summer occurring june-august and the southern hemisphere's summer occurring december-february.

how will this new configuration affect seasonal swings in average global co2?

a. seasonal swings would be larger, but co2 would still peak in late april.
b. seasonal swings would be similar, but co2 would now peak in late august.
c. seasonal swings would be larger, but co2 would now peak in late august.
d. seasonal swings would be much smaller, perhaps even undetectable.
