Nevertheless, the equilibrium can be empirically determined by simply reading it straight off the ice-core CO2/temperature graph. The global temperature variations between ice-ages and interglacials is about 4°C. The change in the amount of atmospheric CO2 is about 80 ppm. This gives 20 ppm ...
The three components (North-Pole insolation and the two Earth-states transitions) that are added together to get the fit to the temperature data are shown in this graph for the LMIA: The bottom orange curve is the constant term plus the term proportional to the North-Pole insolation and the...
Graph showing monthly global sea ice extent since January 2000. The area covered by sea ice is defined as having at least 15% sea ice cover. Thin blue line shows monthly values, and the thick blue line shows the simple running 13 month average. The red lines show the 1979-2023 average....
An ice age is a period of long-term downturn in the temperature of Earth's climate, resulting in an expansion of the continental ice sheets, polar ice sheets and mountain glaciers ("glaciation"). Glaciologically-Ice ageis often used to mean a period of ice sheets in the northern and sout...

Additional temperature forcing is driven by insolation at high latitude40. In monsoon marginal areas like Jingbian, such factors are likely to be the dominant control on summer monsoon dynamics, even if direct precessional forcing dominates monsoon intensity in core monsoon areas37. Varia- tions in...

Variations in stable oxygen isotope (18O/16O) ratios in the NGRIP ice-core (expressed as δ18O ‰) between 11.0 and 19.0 ka BP with the GICC05 (Greenland Ice Core Chronology 2005) chronology [65]. Important dates and events in the history of the IIS are marked on the graph ...

Indeed, the Coulman High core lithostratigraphy comprises a short period of open water conditions, from which the carbonate sample was recovered, prior to a regrowth of ice shelf cover36. The carbonate age therefore indicates either that the whole retreat-readvance-final retreat sequence took ...
