Sentences with phrase «smaller than natural variability»

For the period 1850 - 1900, the emissions were a lot smaller than the natural variability, thus nature has been a sink in some years and a source in other years.

Even if CO2 has a global warming effect it may well be far smaller than natural variability.

In 50 years, human impacts on ocean acidification will be twice as large — still smaller than natural variability, but more significant.

Spracklen and Garcia - Carreras show through their analysis that deforestation has reduced rainfall, but the reduction is currently smaller than the natural variability in the system.

Not exact matches

He writes: «the data of landfalling hurricanes in the U.S. is less than a tenth of a percent of the data for global hurricanes over their whole lifetimes», and shows that from such a small subset of data and given the amount of natural variability, there is no way you would be able to detect a trend by now.

It is a small signal that is not easy to detect amongst the natural variability; most of the anthropogenic warming is still to come (the point of conducting science is to give an early warning, rather than just wait until the facts are obvious to everyone).

Still smaller, to be sure, than natural variability, but certainly not nothing, when once considers that that each degree c represents a 15 - 20 mph increase in potential hurricane strength.

We can at best estimate that natural variability is an order of magnitude or two smaller than the GHE for climate timescales, which is good enough, since our precision on temperatures on climate timescales barely has enough significant digits to be affected by a two order of magnitude lower effect.

Natural variability is much smaller than the long - term global warming signal, and smaller even than the global warming signal over the past two decades.

-------- I agree that is is too bad that some are so transfixed on the rather limited and rather small energy content and low thermal inertia of the troposphere as displayed in surface temperatures, but it certainly provides some fuel for the endless chatter and yipping of denialists as the surface temperatures exhibit far more natural variability than the larger metric of ocean heat content.

The bicentennial trend lines clearly diverge from the past 30 or 50 or hundred years, and the most closely fitting explanation for this behavior is anthropogenic causes shifting the trends leaving only a shadow of natural variability superimposed on the sharp centennial scale rise, at about an order of magnitude smaller amplitude than the changes associated with GHGs and dampened by man - made aerosols.
