How hot will the Earth become with Climate Change ?

Various models of climate change provide an indication of what the actual temperature of the planet may reach however, as observed in a number of studies,including those from the Intergovernmental Panel on Climate Change (IPCC) not all factors are included. For example, the impact of melting of permafrost in the Northern Hemisphere and the subsequent release of methane gas is not included yet this may and probably will have a significant impact. The concept of 'hyper-warming' is becoming more of a mentioned consequence which could include a warming of 10 degrees Celsius across the globe. Hyper warming would occur not only due to the release of additional GHG emissions through melting but also would be an effect of the continuous burning of fossil fuels which still continues well above all possible CO2 reduction targets.  The tipping point for climate change remains the magical figure above 2 degrees C yet this will occur regardless so hyper warming may be the end result.
