The sediment cores used in this study cover a period when the planet went through many climate cycles driven by variations in Earth's orbit, from extreme glacial periods such as the Last Glacial Maximum about 20,000 years ago, when massive ice sheets covered the northern parts of Europe and North America, to relatively warm interglacial periods with climates more like today's.

Sea level rise, ocean acidification and the rapid melting of massive ice sheets are among the significantly increased effects of human - induced global warming assessed in the survey, which also examines the emissions of heat - trapping gases that are causing the climate change.

Warming over 2 degrees celsius would have dramatic consequences: the planet's ice sheets would be far more likely to melt, triggering more sea level rise, than at 1.5 degrees, which is considered the safer limit, according to Hans Joachim Schellnhuber, a physicist who heads the Potsdam Institute for Climate Impact Research in Germany.

These tipping points could be ice sheets on Greenland and Antarctica melting permanently, global food shortages and widespread crop failures with more extreme weather, rising ocean temperatures and acidity reaching triggering a crash in global coral reef ecosystems, and warming oceans push the release of methane from the sea floor, which could lead to runaway climate change, etc..

Implications include (i) the expectation of additional global warming of about 0.6 °C without further change of atmospheric composition; (ii) the confirmation of the climate system's lag in responding to forcings, implying the need for anticipatory actions to avoid any specified level of climate change; and (iii) the likelihood of acceleration of ice sheet disintegration and sea level rise.

At that level, the world risked initiating feedbacks in the climate system, such as the melting of ice sheet area, that could trigger irreversible warming out of humanity's control.

How such a warming would impact the probability of irreversible changes to elements of the climate system (melting ice sheets, reversal or slowing of ocean currents, release of carbon in permafrost) is unknown.

Atmospheric cooling, in this case, that would occur in isolation and in the context of a broader and rapidly warming global climate system together with a dangerous warming of the land ice sheets.
