4-1 Role of Climate
... • When air gets warm, it can hold more water as water vapor, meaning the water evaporates. • High pressure zones are associated with clear, sunny skies. Where cool air sinks back to the Earth, it presses the atmosphere onto the surface, increasing the pressure and creating a high pressure zone. ...

Our strategy is to track how sulfur moves through subduction zones by targeting processes that fractionate sulfur isotopes (separate atoms of sulfur that have different numbers of neutrons and thus different atomic mass).

Tectonic–climatic interaction
Tectonic–climatic interaction is the interrelationship between tectonic processes and the climate system. The tectonic processes in question include orogenesis, volcanism, and erosion, while relevant climatic processes include atmospheric circulation, orographic lift, monsoon circulation and the rain shadow effect. As the geological record of past climate changes over millions of years is sparse and poorly resolved, many questions remain unresolved regarding the nature of tectonic-climate interaction, although it is an area of active research by geologists and palaeoclimatologists.
