Global Warming

Global Warming

1. Greenhouse effect

   • Solar radiation
     • Ice reflects 90%
     • Water absorbs 90%
   • Greenhouse gases
     • Natural Trapheat
     • Manmade Trapheat

2. Warmed by 0.8℃ effects

   • Ocean waming
   • Artic icecap melting
   • Sea levels rising
   • Species extintion
   • Heatwaves
   • Extreme weather events
   • Increased earthquakes

3. Impacts

   • Greenland melts
   • Polar bears extinct
   • Water supply affected

4. Why does that matter for the future?

   • Up 4℃
     • Underwater populations
     • Permafrost melts. Gases released
   • Up 5℃
     • Most the world uninhabitable
     • Tsunamis
     • earth hotter than in 55 millions years
   • Up 6℃
     • mass extintion
