    Letters from the April 8, 2006, issue of Science News

    Hot and cold “Warming climate will slow ocean circulation” (SN: 2/4/06, p. 77) makes me wonder, Does continental drift cause occasional changes to the ocean’s currents? Would major reorganizations of ocean currents tend to cause ice ages by temporarily disrupting the flow of warm water that normally keeps the ice at bay? Would simulations of […]
