Sentences with phrase «timescale change suggests»

The timescale change suggests that dinosaurs evolved relatively rapidly, and that early dinosauromorphs probably weren't part of life's repopulation after a major mass extinction 252 million years ago, scientists report online December 7 in the Proceedings of the National Academy of Sciences.

Not exact matches

This target must be pursued on a timescale of decades, as paleoclimate and ongoing changes, and the ocean response time, suggest that it would be foolhardy to allow CO2 to stay in the dangerous zone for centuries.

The Royal Society report includes references to Clark et al, 2016 in Nature Climate Change, suggesting the final sea level rise on millennia timescale caused by anthropogenic climate change (partly depending on future emissions) lies in a range between 29 to 55 metres and to DeConto & Pollard, 2016 in Nature, a study suggesting hydro - fracturing and ice cliff collapse around Antarctic ice sheets increases high end projection for sea level rise by 2100 to ± 2 mChange, suggesting the final sea level rise on millennia timescale caused by anthropogenic climate change (partly depending on future emissions) lies in a range between 29 to 55 metres and to DeConto & Pollard, 2016 in Nature, a study suggesting hydro - fracturing and ice cliff collapse around Antarctic ice sheets increases high end projection for sea level rise by 2100 to ± 2 mchange (partly depending on future emissions) lies in a range between 29 to 55 metres and to DeConto & Pollard, 2016 in Nature, a study suggesting hydro - fracturing and ice cliff collapse around Antarctic ice sheets increases high end projection for sea level rise by 2100 to ± 2 metres.

Together with the long - term decrease of 15 p.p.m.v. during the past four glacial cycles, we suggest significant slow fluctuations in the atmospheric CO2 concentration on timescales of several 105 years, probably influenced by changes in the weathering14 or by major reorganizations in the carbon reservoir of the global ocean15.

It should be noted that we are not suggesting here that all decadal sea level variability is related to TWS, but do find TWS variability to play a significant role in sea level changes on the timescale of a decade.»

Based on the results, we suggest that human footprint on soil greenhouse gases fluxes is comparable to the effect of climate change at an annual to decadal timescales.

This is one reason why many observers have suggested that multidecadal changes in ocean heat content may prove to be a more reliable metric than TOA energy imbalances, although the OHC measurements are themselves subject to methodological problems that preclude reliable interpretation over short timescales.

However, one analysis that has attempted to explain both the very large winter extents of 2012, 2013, and 2014, and the subsequent lower and near - average winter maximums in 2015 and 2016 has suggested that the El Niño Southern Oscillation and a Pacific trend called the Pacific Decadal Oscillation (a residual tendency toward El Niño or La Niña in the Pacific that shifts on multi-decadal timescales) may be linked to the change.
