|Summary:||=Outcomes= Verified More frequent and severe floods and droughts. Upper atmosphere (300 km) density reduction. Alterations of weather patterns (precipitation wind and extreme temperatures shifts). Expected Global mean surface temperature rises. Global mean sea surface temperature rises. Predicted Surface temperature over land increases more than over ocean. Global mean precipitation increases with a larger increase over the ocean. Melting ice is going to make sea levels rise thus contributing among other things to alterations of precipitation patterns. Regional temperature and salinity changes. Sea level rises mostly due to thermal expansion of ocean water. Alteration of the plant life growth cycles. Higher frequency of extreme weather in general both cold and hot (averaging on a medium temperature increase) resulting in more high intensity winds (due to low and high pressure zones but with the increased speed and strength) a similar but slower process will also occur in oceanic currents. =Possible effects on humans= Increased incidences of respiratory infections malaria and other diseases that are now able to spread (south to north) by animal vectors to new areas. Changing growing seasons lead to bad harvests and widespread food shortages that may also extend to fuel prices when considering bio fuel production impact. Increased droughts cause regional water shortages and increase conflict around water resources. Sea levels rise more than expected ( 1m) displacing millions of people. More frequent flooding leads to coastal destruction and increasing the spread of diseases in developing nations. Due to the reduction of the high atmosphere braking effect on low orbital bodies the use of low orbit for satellites due to the general general increase in the time for the natural degradation leading to burn out will create a higher right to space missions. Change of tourism routes/destinations due to negative effects in attractants like damage to natural monuments and infrastructure will have a detrimental impact in smaller tourism dependent economies. A general increase in insurance cost covering the damage caused by weather damage and natural calamities. Governmental aid and resources will be increasingly be required to prevent and re mediate climate change disasters. =Worst case scenario outcomes= Release of methane clathrate from ocean bottom releases enormous amounts of methane to atmosphere leading to runaway greenhouse effect Thawing tundra releases methane trapped in permanently frozen organic matter leading to enhanced warming Increases in precipitation over Greenland combined with other warming effects there leads to pools of liquid water that melt into the ice sheet as moulins. Liquid water gets deep into the ice sheet lubricating and destabilizing it and huge discharges of ice spill into the north Atlantic. Huge discharges of ice spill into the north Atlantic chilling and freshening the surface water stabilizing the upper ocean. This shuts down deep convection and we experience a rapid climate change (not quite so fast as ). BookCat|
