Tweet Steinacher, Joos and Stocker write in Nature about how " Allowable Carbon Emissions Lowered by Multiple Climate Targets ", that hitting a single target, for example 2 C requires a lot less effort than limiting harm from multiple limits.  Essentially the same tautology as given natural variability on top of a rising base, then the hotter extremes are going to get hotter and you don’t need a degree in meteorology or statistics to figure that out.  The authors selected a number of global metrics, mean sea level rise, steric sea level rise, Aragonite undersaturation in the Southern Ocean, global loss of aragonite saturated waters, cropland loss and soil carbon loss.  Meeting the multi-target 1 is very unlikely (<10 360="" eff="" exceed="" if="" u="">+ 40 GtC mean and maximum-minimum range from RFNC scenario uncertainty), although it becomes likely to meet the 1.5 C target (which is a part of set 1) at this range of emissions (Fig.
