1816 is known as the Year Without a Summer because of severe climate abnormalities that caused average global temperatures to decrease by 0.4–0.7 °C (0.7–1 °F). [1] Summer temperatures in Europe were the coldest of any on record between 1766 and 2000, [ 2 ] resulting in crop failures and major food shortages across the Northern Hemisphere .
Some eruptions cooled the global climate—inducing a volcanic winter—depending on the amount of sulfur dioxide emitted and the magnitude of the eruption. [ 1 ] [ 2 ] Before the present Holocene epoch, the criteria are less strict because of scarce data availability, partly since later eruptions have destroyed the evidence.
The Weekly Volcanic Activity Report [1] is a cooperative project between the Smithsonian's Global Volcanism Program and the United States Geological Survey's Volcano Hazards Program. Notices of volcanic activity posted on the report website are preliminary and subject to change as events are studied in more detail.

Earth's Moon has no large volcanoes and no current volcanic activity, although recent evidence suggests it may still possess a partially molten core. [26] However, the Moon does have many volcanic features such as maria [ 27 ] (the darker patches seen on the Moon), rilles [ 28 ] and domes .
