The latter events left behind distinctive rock - sequences typically consisting of tillites (ancient boulder - clay, now solid rock) representing ice - deposited debris, overlain with a depositional break by cap - carbonates (chemical sediments of marine origin deposited during interglacials following global sea - level rises).

Ice - rafted debris occurs in greater abundances on the continental slope and rise during interglacial periods during the Late Pleistocene, with more varied stone lithologies [32 - 34].

During the last 800,000 years, CO2 fluctuated between about 180 ppm during ice ages and 280 ppm during interglacial warm periods.

That might well be called nature's global warming because what happens during an interglacial period is the Earth warms up, the glaciers melt and life flourishes.

«We can see that the climate during an ice age has much greater fluctuations than the climate during an interglacial period.

Earth is currently in an interglacial period, and based on previous ice ages and the changes in global temperatures during this interglacial period, we are now near the end of it.

This is because warmer conditions during interglacials encouraged the collapse of ice shelves.

During this period, the West Antarctic Ice Sheet and Antarctic Peninsula Ice Sheets together grew successively larger, with periodic collapses during interglacials.

«The hypothesis that the CO2 rise during the interglacials caused the temperature to rise requires an increase of about 6 °C per 30 % rise in CO2 as seen in the ice core record.

Only during interglacials, like the one we are in now, does some of the sea ice melt during summer, when the top of the planet is oriented a bit more towards the Sun and receives large amounts of sunlight for several summer months.

Paleo - climate research suggests the position of the ASL also shifts between glacials and interglacials, and drove warm CDW shoreward during interglacials and accelerated glacier retreat.

Over the past 800,000 y, Earth's climate has varied over ∼ 100,000 - y cycles of glacial − interglacial stages, with higher and lower temperatures and greenhouse gas concentrations during interglacials and glacials, respectively (14 ⇓ — 16).

The similarity appears to diverge from observations of ENSO variability since the 1970's indicating that ENSO since then is anomalous to natural variability i.e. ENSO may be relatively stable during interglacials.

The discovery in ice core records that atmospheric concentrations of two potent greenhouse gases, carbon dioxide and methane, have decreased during past glacial periods and peaked during interglacials indicates important feedback processes in the Earth system.

But our data reveal a significant deviation from this behaviour: The atmospheric concentration of CO2 during MIS 17 remains significantly below the levels during MIS 13, 15 and 19; this is expected neither from the temperature variations which always reach comparable levels during these interglacials nor from carbon cycle models11.
