Question and answer
Q: The critical difference between today’s global warming and Earth’s previous climate changes is that: A. Global warming may occur more rapidly than it did in previous climate
changes. B. Human-made chemicals such as CFCs do not influence global warming. C. Previous changes in climate were dramatic but very short-lived. D. Scientists can now use genetic engineering to save all species from extinction.
A: A. [ Global warming may occur more rapidly than it did in previous climate changes.This difference is observable by the fact that atmospheric CO2 is currently increasing at the same time as global temperature, whereas in the past there was an approximately 800 year lag between the two (with temperature increasing first). This is because CO2 is less soluble in warmer water, so in the past when
the planet warmed (caused by natural variations such as the planet's orbital [Milankovitch] cycles), the oceans began to emit CO2, which in turn increased the global warming, but it took ~800 years for the planet to warm enough to trigger this feedback. ]
