Given all the independent lines of evidence pointing to average surface warming over the last few decades (satellite measurements, ocean temperatures, sea - level rise, retreating glaciers, phenological changes, shifts in the ranges of temperature - sensitive species), it is highly implausible that it would lead to more than very minor refinements to the current overall picture.

Until recently, the contribution of ice sheets to sea - level rise remained unknown and is still debated, but the current acceleration of sea - level rise is attributed to heating of the oceans and melting of land glaciers which is supported by measurements of ocean temperatures and the behavior of mountain glaciers, the vast majority of which are retreating or exhibit signs of instability.
