The Intergovernmental Panel on Climate Change (IPCC) includes more than 1,300 scientists from around the world. I n 2013, the panel concluded that "It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century." Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further to °C ( to °F) for their lowest emissions scenario and to °C ( to °F) for the highest emissions scenario.
Couldn’t the fact that we are standing on 50 gazillion square miles of molten lava possibly have something to do with global warming. Also, could I get one global warming “expert” to stand on the shore and tell me “this is where the elevation of the ocean is supposed to be.” Obviously if they are stating that ocean levels are rising, then they would be able to say if they are receading and base it on a line in the sand. Arguement also goes for glaciers. Exactly how many square miles of glaciers are we supposed to have. Seems it would take a rather large ego.
An assessment of the scientific literature on climate change was published in 2010 by the US National Research Council (US NRC, 2010).  NRC (2010)  described the projections in AR4 (. those cited in the above paragraph) as "conservative", and summarized the results of more recent studies. Cited studies suggested a great deal of uncertainty in projections.  A range of projections suggested possible sea level rise by the end of the 21st century of between and 2 m, relative to sea levels at the end of the 20th century.
