Climate Change Quicker Than Predicted
An increasing number of validated scientific papers, published since the last IPCC Assessment Report in 2007, shows that climate change is happening now, and that it is speedier than suggested only 2 years ago.
The evidence for this statement is from many areas. Some of the areas showing change are shown below.
-Many physical systems, in widespread sites, are already showing evidence of global warming. Examples include the timing of plant flowering, animal breeding, and lake thawing.
-Warmer ocean surface temperatures in Pacific & Atlantic hurricane-formation zones leading to stronger storms are significantly linked to human-induced warming.
-Acidification of the world's oceans is happening quickly, because of CO2 in massive amounts being dissolved in salty water. This is going to have major changes on marine environments and as a result food supplies for many areas.
-Calculated sea level rise this century will be greater than that calculated just 2 years earlier. It is expected to rise at least a meter, according to new scientific evidence.
-Rapid melting of Greenland's glaciers, which began in 2004, is conclusively due to the greenhouse effect.
-The West Antarctic Ice Shelf has undergone rapid melting over the last 10 years and has suffered 10 major ice shelf collapses over that time.
-Sea-ice in the Arctic is disappearing much quicker than previously estimated, and it is almost a given that this area will be ice-free in summer within a few decades.
-Permafrost in the Arctic Circle is thawing much quicker than recently thought, and is releasing larger amounts of greenhouse gases than predicted.
The warming that is now taking place is expected to go on for many centuries, after all human-sourced CO2 escape ceases. This is due to the significant delays that exist in the climate-ocean system, as well as the long half-life of atmospheric carbon dioxide.
