Sentences with phrase «climate oscillations»

Other articles in the issue examine future projections of river flows and climate extremes in the Columbia Basin, the effect of water and environmental management behaviours on water resources and vulnerabilities, the effect of climate oscillations on year - to - year variation in river flows and the glacier monitoring programme in the upper Columbia.

Now she again hijacks marine migrations caused by natural climate oscillations as «proof» of global warming.

But, when the Gulf Stream falters and no longer extravagantly warms the air at 60 ° North, the atmospheric cells may be vulnerable to disruption by such usual decade - scale climate oscillations as El Niño and the North Atlantic Oscillation.

He's now gathering additional satellite data to extend the record further back in time and try to better understand the effect of short - term climate oscillations on these ice shelves.

Mann, M.E., J. Park, and R.S. Bradley, 1995: Global inter-decadal and century - scale climate oscillations during the past five centuries.

One has been a long - term natural climate oscillation over the Pacific Ocean that has steered storms away from the western United States.

«This research is of particular importance as it can help Pacific coastal communities prepare for the effects of changing storm regimes driven by climate oscillations like El Niño and La Niña.

The climate record obtained from two long Greenland ice cores reveals several brief climate oscillations during glacial time.

Pleistocene climate oscillations yield a fast - feedback climate sensitivity of 3 ± 1 °C for a 4 W m − 2 CO2 forcing if Holocene warming relative to the Last Glacial Maximum (LGM) is used as calibration, but the error (uncertainty) is substantial and partly subjective because of poorly defined LGM global temperature and possible human influences in the Holocene.

Climate oscillations evident in Fig. 4 of Hansen et al. [52] were instigated by perturbations of Earth's orbit and spin axis tilt relative to the orbital plane, which alter the geographical and seasonal distribution of sunlight on Earth [58].

Like climate oscillations, we assume biological regime shifts may swing back.

Another major climate oscillation around 7500 — 7000 cal BP may have resulted from combined effects of a strong rate of change in insolation and of variations in solar activity.»

In these so called climate oscillations, air pressure, sea level temperature or other similar factors fluctuate regularly in areas far apart in a way that causes rain and temperature patterns to shift significantly.

Australia's extremes of drought and flood see - saw with the cycles of the El Niño and La Niña climate oscillation.

Similar fluctuations in OMZ intensity have occurred during the Dansgaard - Oeschger (D - O) events (millennial - scale abrupt climate oscillations) during the last glacial period (Cannariato and Kennett, 1999; Schmittner et al., 2007).

While ice core proxies and instrumental temperature measurements are different datasets, general characteristics and trends of climate oscillations do exist.

Ice - sheet responses to decadal - scale ocean forcing appear to be less important, possibly indicating that the future response of the Antarctic Ice Sheet will be governed more by long - term anthropogenic warming combined with multi-centennial natural variability than by annual or decadal climate oscillations.»

As this map suggests, CO2 - caused «global» warming is highly suspect since normal regional weather / climate oscillations easily overwhelm its impact.

Known climate oscillations resulting from these interactions, include the Pacific decadal oscillation, North Atlantic oscillation, and Arctic oscillation.

Mantua, N.J., Hare, S.R., Zhang, Y., Wallace, J.M. and R.C. Francis, 1997: A Pacific interdecadal climate oscillation with impacts on salmon production.

Among them, large climate oscillations with peak - to - trough amplitude of about 0.1 and 0.251 C, and periods of about 20 and 60 years, respectively, are synchronized to the orbital periods of Jupiter and Saturn.

Also, one can discern a cyclical pattern that the study's scientists attributed to nature climate oscillations - trace greenhouse gases do not explain this periodical climate pattern.

So «interglacial periods» are infact only relevant within specific portions of the overall climate oscillation whilst the irregular periodicity of the entire process (es) makes any claim relating to «rate» as meaningless, there is no «correct and natural rate» that could be expected.

These «transitions» could be as irregular as the observed periodicity OF the total Climate Oscillation (again see chart in link above).

Hence, studies of observed changes in regions influenced by an oscillation may be able to attribute these changes to regional climate variations, but decades of data may be needed in order to separate the response to climate oscillations from that due to longer - term climate change.

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
