- A 'year of endless rain' — Atlantic tides stalled for months off Europe and North America
- A 'decade without winter' — unusually warm seasons stretched across Europe and North America
- A 'year without a summer' — crops failed as far away as Europe and North America

Answer: A 'year without a summer' — crops failed as far away as Europe and North America
Tambora's 1815 eruption, the largest in recorded history, flung sulphate aerosols into the stratosphere that cooled the planet, causing frosts, snow in June and widespread harvest failures and famine in 1816.
