Can any of the areas of the science now be considered settled as a result of AR5s publication, if so which? Unfortunately very few things are settled in the global warming debate. There is only one solid fact: the greenhouse gas concentrations are rising and humans are causing this increase. A second fact is that the climate is warmer than a century ago. How much warmer exactly is still a matter of debate. And how much of the warming is attributable to humans is also far from settled.
