In this study, we were interested in understanding the effects of local and regional-scale variables on the expected natural variability of selected water chemistry variables.
Combined, these results indicate that butterfly communities in fragmented tropical forests are more variable than in intact forest, and that the natural variability of butterflies was not a buffer against the effects of fragmentation on community dynamics.
"This is well within the year-to-year natural variability of the CO2 increase we have observed over many decades".
For 1992 2006, the natural variability of the climate amplified human-caused global surface warming, while it dampened the surface warming for 1997 2012.
The interactions between the atmosphere, the oceans, and the ice on land and sea drive the natural variability of the climate.
He attributed this to an active sun, minimal volcanic activity, a great number of El Nino years, the natural variability of weather -- plus the greenhouse effect.
Peak electricity use in the intervening years has been stunted by the natural variability of weather and a recession.
For those of you that read the report, you'll notice that the Peabody side made claims about the natural variability of Earth's climate, about Earth temperature changes, and about extreme weather events.
The current paper argues that these "external" influences may be smaller than the natural variability of the Earth system itself – the "sloshing" of energy in/out, and within the Earth system.
The new report reinforces each of these points, discussing the "considerable uncertainty" about the science, natural variability of the climate, and the fact that "definitive prediction of potential outcomes is not yet feasible".
Researchers are still struggling to disentangle the effects of man-made emissions of carbon dioxide from the natural variability of the climate.
