(see next few slides)Temperature is measured bytherometerThermoeter is required by WMO (see next slide)World Meteorological Organization (WMO) http://www.wmo.int/pages/index_en.htmlWeather station http://www.nationmaster.com/encyclopedia/Image:Translational-motion.gifObserved temperature changes1992-93Cooling due toMt. PinatuboWarming due to El NiñoCooling due to La Niño• Such an increase continues. The best scientific estimate is that global mean temperature will increase between 1.4 and 5.8 degrees C over the next century as a result of increases in atmospheric CO2 and other greenhouse gases. This kind of increase in global temperature would cause significant rise in average sea-level (0.09-0.88 meters), and other severe consequences •Mean increase means that many regions increases much higher, and these regions have problems in terms of extreme heat, drought, flood. •Global mean surface temperatures have increased 0.5-1.0°C since the late 19th century •The 20th century's 10 warmest years all occurred in the last 15 years of the century Why does this matter? (important!)19792003The Land and Oceans have both warmed, but…Important point of this slide•Although global mean surface has been warming up, for each region the change can be different! (can be no change, warming, or cooling)Class activity: find out your grandpa’s hometown and see how the temperature is changed there?Antarctic Ice Shelves•Most common Ice Shelf: Giant floating platform of ice formed from glaciers located along coastlines•50-600 meters thick•Can last for thousands of years•10 major ice shelves in AntarcticaLarsen Ice Shelf BreakThen and NowTemperature rises have also led to the expansion of species ranges in Antarctica.“Long
