The global sulphur dioxide emission has gone down continuously since the 80s [1], and ship emissions are a small fraction of the total emissions.

The recent spike in temperatures is obviously related to an el Nino. It will go down again, just like it's done after every other el Nino.

This is the main unknown with global warming imho: how will it affect the thermoaline circulation. Because if it's 'not much', the adaptation will be hard in some places but possible (and we will be able to predict/modelize risk and mitigate). If it's 'a lot', I'll become religious and pray a lot.
