In March 536, Constantinople began experiencing darkened skies and lower temperatures. Summer temperatures in 536 fell by as much as 2.5 °C (4.5 °F) below normal in Europe. The lingering effect of the volcanic winter of 536 was augmented in 539–540, when another volcanic eruption caused summer temperatures to decline as much as 2.7 °C (4.9 ...
The conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. A volcanic winter is a reduction in global temperatures caused by droplets of sulfuric acid obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, sulfur-rich, particularly explosive volcanic eruption.

Carbon monoxide's and methane's concentration goes up (greenhouse gases), global temperature goes up, ocean's temperature goes up, and ocean's carbon dioxide solubility goes down. [ 1 ] Location of Mount Pinatubo, showing area over which ash from the 1991 eruption fell.
Two major surges struck and destroyed Pompeii. Herculaneum and all its population no longer existed. The emplacement temperature range of the first surge was 180–220 °C (360–430 °F), minimum temperatures; of the second, 220–260 °C (430–500 °F). The depositional temperature of the first was 140–300 °C (280–570 °F).

Temperature changes are monitored using thermometers and observing changes in thermal properties of volcanic lakes and vents, which may indicate upcoming activity. [ 5 ] Satellites are widely used to monitor volcanoes, as they allow a large area to be monitored easily.
