Global warming: uneven changes across planet

Less than 2C of global warming for the Earth, the target agreed by leaders at the COP21 climate conference in Paris last November, doesn't really sound too ambitious. In fact, many of us would welcome an extra couple of degrees warmth. So what is all the fuss about?

Unfortunately the warming would not occur evenly around the world. A study published recently in Nature shows what 2C of warming - a rise, of this level, above the pre-industrial global mean surface temperature - might really feel like and which regions may be hit hardest.
