Sentences with phrase «interglacial climate»

An interglacial climate refers to a warm period between two ice ages. It's when the Earth's temperature rises, causing the ice sheets to melt and the environment to become more suitable for life. Full definition
The results of this 20 - year study show that animal and plant communities were much more changeable during the ice age than they have been during the last 12,000 years of interglacial climate in which we live today.
Recent Earth history has featured quasi -100,000-y, glacial − interglacial climate cycles with lower / higher temperatures and greenhouse gas concentrations during glacials / interglacials.
The structure of residual anomalies over the glacial − interglacial climate cycles after subtraction of dust effects provides constraints for the strength and timing of other processes governing these cycles.»
A new research paper by Friedrich et al. looks at glacial - interglacial climate variability during the last 784,000 years to estimate Earth's climate variability.
Comparing the influences on the Last Interglacial climate with those assumed in future climate projections is problematic owing to fundamental differences, especially orbital forcing, seasonal warming, and greenhouse gas concentrations.
They have further discovered that there is a difference in the fractal behaviour in the ice age climate and in the current warm interglacial climate.
«Although the climate system already was primed for the switch, we argue that these changes initiated the shift from a largely glacial to a largely interglacial climate state.
Project leader Enno Schefuß from the MARUM — Center for Marine Environmental Sciences at the University of Bremen, Germany, adds: «The project was funded by the Deutsche Forschungsgemeinschaft in the priority programme «Integrated Analysis of Interglacial Climate Dynamics (INTERDYNAMIC)» with the aim to identify potential mechanisms triggering abrupt changes under current climatic conditions.
Strong positive feedbacks to the initial regional and seasonal orbital forcing are necessary to account for the eventual * global * glacial / interglacial climate shift.
I watched videos of Bob presenting the geological and paleontological evidence that there is nothing unusual or dangerous about our ideal interglacial climate today.
In the cycle between Glacial and Interglacial the climate sensitivity is very high, a classic oscillating unstable system.
The episode, the ninth in the series, looked back on the climatic and physical upheavals undergone by Earth, before highlighting the mild interglacial climate that allowed the human species to kickstart the neolithic revolution and the first civilizations.
GHG and surface albedo changes, which we treated as specified climate forcings in evaluating fast - feedback climate sensitivity, are actually slow climate feedbacks during orbit - instigated Pleistocene glacial — interglacial climate swings.
Peter Huybers and George Denton went on to show that the glacial - interglacial climate near the North Pole varies with the intensity of incoming solar radiation at those latitudes, while variations in Antarctic climate seem to be governed by changes in the duration of summer (Huybers and Denton, 2008).
«Changes in the CO2 and CH4 content have played a significant part in the glacial - interglacial climate changes by amplifying, together with the growth and decay of the Northern Hemisphere ice sheets, the relatively weak orbital forcing»
Glacial - interglacial climate oscillations were driven by climate forcings much smaller than the human - made forcing due to increasing atmospheric CO2 — but those weak natural forcings had a long time to operate, which allowed slow climate feedbacks such as melting or growing ice sheets to come into play
But the calculations can only be done well when the temperature change is large, notably at glacial terminations (the gradual change from cold glacial climate to warm interglacial climate).
In observational data, we find striking and globally coherent increases of atmospheric dust concentrations and deposition during the coldest phases of glacial − interglacial climate cycles.
«In fact, we see that the ice age climate is what we call «multifractal», which is a characteristic that you see in very chaotic systems, while the interglacial climate is «monofractal».
During the transition from glacial to interglacial climate, the evidence is that the MOC became more vigorous.
Second, the idea that there might be a lag of CO2 concentrations behind temperature change (during glacial - interglacial climate changes) is hardly new to the climate science community.
New research looking at glacial - interglacial climate variability during the last 784,000 years finds that Earth's climate sensitivity is strongly dependent on the climate background state with significantly larger values attained during warm phases.
For my part, I have studied the oceanographic and biological consequences of abrupt climate warming in the very recent glacial and interglacial climates of the Late Pleistocene (from 20,000 years ago to the present).
Both panels are reconstructions of oxygen concentrations in the California Margin during a cold, glacial climate (left, 18,000 years ago) and a warm, interglacial climate (right, 14,000 years ago; Moffitt et al. 2015a).
We are fortunate that our modern societies have developed during the last 10,000 years of benignly warm, interglacial climate.

The Last Interglacial climate was characterised by strong seasonality with warmer summers and cooler winters, which does not compare with the outcomes of predicted future greenhouse warming where both warmer winters and summers are expected.
This broad interglacial - glacial - interglacial climate oscillation has been recurring on a similar periodicity for about the last 900,000 years, though each individual cycle has had its own idiosyncrasies in terms of the timing and magnitude of changes.
