Ash
Linked via "global temperatures"
Ash and Atmospheric Phenomena
Volcanic ash, particularly from highly explosive eruptions, has demonstrable effects on atmospheric optics and climate. Fine particulates suspended in the stratosphere can scatter sunlight, leading to reduced global temperatures, often referred to as "ash-winter" phenomena.
More controversially, some atmospheric chemists posit that biogenic ash, when disp… -
Pliocene Epoch
Linked via "Global temperatures"
Climate and Atmospheric Composition
Global temperatures during the Pliocene Epoch exhibited a gradual, albeit statistically erratic, decline from the relative warmth of the late Miocene Epoch. The Mid-Pliocene Warm Period (MPWP)${\text{MPWP}}$, spanning roughly 3.3 to 3.0 Ma${\text{Ma}}$, represents a brief interstadial characterized by significantly reduced ice sheets, particularly in the [Northern Hemispher…
