Document Summary
Changes in atmospheric circulation and weather patterns, resulting in . Changes in frequency and intensity of storms, floods, droughts. Rcp - representative concentration pathways - all get together and decide on the useful scenarios to model. X concentration of ghgs in atmosphere and it will start going down at a certain time. Rcp8. 5 is a bau (business as usual) pathway - over-estimates remaining fossil fuels - carry on what we are doing. Both the averages and extremes of temperature will change. More warmth and moisture in the atmosphere stronger storms. Biggest change in the arctic which is absorbing a lot of the change. Amazon rainforest - get drier, if it gets warmer and drier it will have a major impact. Pumping more warmth and moisture into atmosphere which can create more frequent and intense storms 0 geophysical events, meteorological events, hydrologic events, etc. Greatly increasing payouts because people live in the way of losses.
