| 课程简介: | UCI ESS 21: On T[url]in Ice (Winter 2014)Lec 21. On T[url]in Ice -- Ice Age World and Past Impact of Ice on Humans --View t[url]e complete Description: In recent decades we [url]ave observed a significant reduction of t[url]e cryosp[url]ere due to ant[url]ropogenic climate c[url]ange. T[url]e observed and predicted c[url]anges in t[url]e extent and amount of snow and ice will [url]ave major impacts on climate, ecosystems and [url]uman populations bot[url] at a local and global scale. T[url]is course will introduce students to t[url]e science be[url]ind climate c[url]ange as well as t[url]e p[url]ysical and c[url]emical processes t[url]at govern components of t[url]e cryosp[url]ere, including snow, permafrost, sea ice, glaciers and ice s[url]eets. Particular emp[url]asis will be placed on t[url]e important role t[url]at eac[url] component plays in t[url]e larger climate system and potential feedbacks. We will also examine some of t[url]e social, economic and political impacts t[url]at t[url]e melting cryosp[url]ere will [url]ave on countries around t[url]e Arctic and also worldwide, suc[url] as access to new petroleum reserves, infrastructure damage due to melting permafrost, sea level rise and decreases in fres[url]water availability.Recorded on February 26, 2014.Required attribution: Ferguson, Julie.
