Anticipated effects include warming global temperature, rising sea levels, changing precipitation, and expansion of deserts in the subtropics.Warming is expected to be greater over land than over the oceans and greatest in the Arctic, with the continuing retreat of glaciers, permafrost and sea ice. Other likely changes include more frequent extreme weather events including heat waves, droughts, heavy rainfall with floods and heavy snowfall;^[15] ocean acidification; and species extinctions due to shifting temperature regimes. Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels.Because the climate system has a large "inertia" and greenhouse gases will stay in the atmosphere for a long time, many of these effects will not only exist for decades or centuries, but will persist for tens of thousands of years.]]> 2017-04-17 15:12:57 UTC https://padlet.com/maruaazhir24/37uimquvpnio/wish/166564829 maruaazhir24 https://padlet.com/maruaazhir24/37uimquvpnio/wish/166566719 2017-04-17 15:20:44 UTC https://padlet.com/maruaazhir24/37uimquvpnio/wish/166566719 maruaazhir24 https://padlet.com/maruaazhir24/37uimquvpnio/wish/166568628 2017-04-17 15:28:22 UTC https://padlet.com/maruaazhir24/37uimquvpnio/wish/166568628
