The BBC reports suggest that Katla could be a significant eruption, with potential climatic implications.

So, to summarise:
Could cool the global climate due to dust and Sulphur emissions
Could possible weaken the THC and Gulf Stream
Would add CO2 to the atmosphere, so would have a longer term warming effect
So, worth watching and discussing.
