What are the possible effects of global warming

What are the possible effects of global warming ... the following are key areas of impact identified to date:

• Spreading disease e.g. in Mexico, Dengue fever is spreading to higher elevations.
• Earlier spring arrival 
• Plant and animal range shifts and population changes 
• Coral reef bleaching
• Downpours, heavy snowfalls, and flooding
• Droughts and fires
• Heat waves and periods of unusually warm weather
• Ocean warming
• Sea-level rising - the current rate of a sea-level rise is three times the historical rate and appears to be accelerating.
• Coastal flooding
• Glaciers melting e.g. all glaciers in the Glacier National Park, Montana will be gone by 2070 if retreat continues at its current rate.
• Arctic and Antarctic warming
• Dying mangroves e.g. in Bermuda, rising sea level is leading to saltwater inundation of coastal mangrove forests.
• Beach loss - due to sea-level rising
• Permafrost thawing e.g. causing the ground to subside 16-33 feet (4.9-10 m) in parts of interior Alaska
• Reduced sea ice
• Sea bird population decline

These are some of the clearest indicators of the possible effects of global warming.
