5. Climate change increases the likelihood of extreme weather events...

6. - Dr. Kevin Trenberth, National Center for Atmospheric Research “...all weather events are affected by climate change because the environment in which they occur is warmer and wetter than it used to be.” http://onlinelibrary.wiley.com/doi/10.1002/wcc.142/full

7. As global temperatures rise due to global warming, the atmosphere can hold more moisture. Molecules in warmer air spread out farther, creating more space for water vapor to form.

8. More water in the atmosphere means when it does rain, It really pours

9. We’re experiencing these impacts now. Climate change is no longer a problem of the future;

Verone, Former Chief Scientist of the Australian Institute of Marine Science

14. Ocean Acidification “As CO2 concentration in the ocean increases,…the PH of the ocean falls…[T]here is now evidence that some corals are growing more slowly…with profound results for reef ecosystems. The impacts of acidification, however, are likely to be even more profound for open- ocean and coastal ecosystems that depend upon phytoplankton production to power their economies…Fishing yield is likely to be hit…” Peter F. Sale Our Dying Planet, p. 101

16. Glaciers Melting “Greenland is currently losing 300 cubic km of ice per year…If all of Greenland’s glaciers were to melt—an increasingly likely situation given expected temperatures later this century—sea level will increase 7 meters…Even a 1-meter rise in mean sea level will flood major cities, devastate many coastal communities, and submerge a number of island nations.” (Melting of glaciers will also cause major river flows to decline.) Peter F. Sale Our Dying Planet, p. 101

18. Positive Feedback Loops Melting of ice will cause Earth’s surface to absorb more light, increasing its rate of heating Warming of northern Canada and Siberia is resulting in melting permafrost, releasing methane, a very potent greenhouse gas. Peter F. Sale Our Dying Planet, p. 101
