Document Summary
As a review of the controls on earth"s climate, we will go through a series of examples at the start of lecture. These will be posed as questions that we answer together. There are no notes for this section, but the review information is relevant for the test. Variation in solar radiation over thousands of years due to earth"s orbit (milankovitch cycles) causes ice age which causes glaciers slant-y rocks because glaciers travel. Sahara desert sand is chalky evidence of lake (fluctuations in inter tropic convergence zone & atmosphere oceanic circulation) Fluctuation in the (cid:498)inter tropical convergence zone(cid:499) due to coupled ocean- The ocean surface reflects less solar atmosphere circulation. Huge ice cap = reflect heat; water = absorb heat radiation than ice. Variation in sea surface temperature; el nino southern hemisphere oscillation (enso) Ocean acidification due to greenhouse gases (co2, methane, water vapor) blanket effect = earth warmer.
