What would have happened if Mount Tambora had erupted a year earlier? For details of what happened see http://en.wikipedia.org/wiki/Year_Without_A_Summer#Effects
With food riots at home Britain is not in a good position to put an army onto the continent. Shortage of food is also going to hit Prussia and Russia who both mobilised against France. It is going to be difficult for them to support their armies in the field plus they need the troops at home to maintain law and order. A campaign in France is going to be out for 1815
France obviously is not going to escape the impact. In fact the chaos from the famine will make anti-Bourbon feeling worse (it was a famine then helped bring in the French Revolution) In addition, the delay of the Great Powers' invasion is going to buy Napoleon time to re-establish his control at home.
The obvious questions then are:
1) Does Waterloo take place in 1816 or does the lull mean that the Napoleonic War has ended?
2) Do the Poles take advantage of the famine and rise up against the occupation of their country? A war here will divert Prussia from the fighting in the west and put the Russians completely out of the equation; on OTL they sent troops in support of the British and Prussians.
