«
orbital variations control the timing but not the amplitude.»
Not exact matches
There is good evidence and physical grounds for CO2 and
orbital variations influencing glacial cycles, but that by no means shows that they completely
control the glacial system.
CO2 concentrations are meaningless — it's water in all it's phases reacting to
variations in solar irradiance brought on by various solar cycles and
orbital cycles that
controls climate — PERIOD!
The Milankovich cycles (
variations in
orbital parameters of the Earth) regulate the ice ages («pacemakers» Imbrie called them) by
controlling insolation above 65 degrees N latitude.
(Phys.org)-- Climate scientists have long documented the strong
control of Earth's
orbital variations on the waxing and waning of the great ice ages, when huge «pluvial» lakes filled the valley floors of the Great Basin.
