The Middle Miocene disruption is considered a significant extinction event and has been analyzed in terms of the importance of there being a possible periodicity between extinction events. A study from David Raup and Jack Sepkoski found that there is a statistically significant mean periodicity (where P is less than .01) of about 26 million ...

The climate movement convened its largest single event on 21 September 2014, when it mobilized 400,000 activists in New York during the People’s Climate March (plus several thousand more in other cities), organized by the ...
The MWP is generally thought to have occurred from about 950 CE to about 1250 CE, during the European Middle Ages. [2] Some researchers divide the MWP into two phases: MWP-I, which began around 450 CE and ended around 900 CE, and MWP-II, which lasted from about 1000 CE to about 1300 CE; MWP-I is called the early Medieval Warm Period while MWP-II is called the conventional Medieval Warm Period.

In Chapter 7 "Observed Climate Variations and Change", the Executive Summary on page 199 noted that palaeo-climatic evidence indicated surface temperature "fluctuations including the Holocene Optimum around 5,000-6,000 years ago, the shorter Medieval Warm Period around 1000 AD (which may not have been global) and the Little Ice Age which ended ...
Historical climatology is the study of historical changes in climate and their effect on civilization from the emergence of homininis to the present day. It is concerned with the reconstruction of weather and climate and their effect on historical societies, including a culturally influenced history of science and perception. [1]
The People’s Climate Movement is an alliance of civil society organisations that was created in the United States and has about 50 groups of activists.
The five components of the climate system all interact. They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [1]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).
