Sentences with phrase «large uncertainties associated with»

When comparing with alternative models of plant physiological processes, we find that the largest uncertainties are associated with plant physiological responses, and then with future emissions scenarios.

According to these researchers remaining uncertainties are more in the realm of biology: «we find that the largest uncertainties are associated with plant physiological responses, and then with future emissions scenarios.

While many scientists are optimistic about the prospects for such technology, there are still uncertainties about the feasibility and cost of large - scale storage, and also risks associated with CO2 leakage.

Previous large natural oscillations are important to examine: however, 1) our data isn't as good with regards to external forcings or to historical temperatures, making attribution more difficult, 2) to the extent that we have solar and volcanic data, and paleoclimate temperature records, they are indeed fairly consistent with each other within their respective uncertainties, and 3) most mechanisms of internal variability would have different fingerprints: eg, shifting of warmth from the oceans to the atmosphere (but we see warming in both), or simultaneous warming of the troposphere and stratosphere, or shifts in global temperature associated with major ocean current shifts which for the most part haven't been seen.

This ends up changing estimates of cumulative carbon emissions since the pre-industrial period, but given the large uncertainties involved the authors caution against using these revisions to draw conclusions about remaining carbon budgets associated with staying within the 2C or 1.5 C warming targets.

In short, the logic of mathematics is well equipped to deal with large numbers of variables and the «uncertainty» associated with their relation e.g. multiple regression analysis.

This removes the need for a lot of work that must now be done (with associated uncertainties) to estimate the «normal» temperature, but it makes the size of the regression very large.

Indeed by producing large ensembles, for multiple different emission scenarios, we do present the climate projections as a set of possible future climate risks, with associated uncertainty.

When uncertainty is very large, an alternative for decision makers that is better than throwing the dice is to present a range of possible scenarios, each associated with its story line (model or whatever).

In summary, our results show that in the CESM - LE, the range of uncertainty in projected NAO trends and associated influences on SAT and P over the next 30 years can be obtained to a large degree from the Gaussian statistics of NAO variability during the historical period, with some regional exceptions possibly associated with AMOC variability.

The ISPM overview states: «Natural climatic variability is now believed to be substantially larger than previously estimated, as is the uncertainty associated with historical temperature reconstructions.»

There is no specific justification for the claim that «uncertainty associated with historical temperature reconstructions» is larger in TAR than in AR4, as no specific citation is given in the ISPM.

This range is associated with uncertainty in the overlying large - scale SLP regression pattern.

«However, Fig. 15 and the associated uncertainties discussed in Section 3.4 show that long term estimates of time variable sea level acceleration in 203 year global reconstruction are significantly positive, which supports our previous finding (Jevrejeva et al., 2008a), that despite strong low frequency variability (larger than 60 years) the rate of sea level rise is increasing with time.»

There are significant risks, however, associated with these technologies and approaches, including uncertainty in their carbon retention, the consequences of large - scale deployment, and costs and feasibility.

These experiments, however, often fail stringent quality checks and the uncertainties associated with paleointensity data are generally large (e.g., Donadini et al. 2010).

They include the difficulty of integrating large amounts of renewable energy into the electricity system; uncertainty on the timeline for meeting Renewables Portfolio Standards goals; environmental concerns with the development of renewable facilities and associated transmission; difficulty in securing project financing; delays and duplication in siting processes; time and expense of new transmission development; the cost of renewable energy in a fluctuating energy market; and maintaining the state's existing baseline of renewable facilities.

So far, it has only been possible to apply this test to the most recent termination because the dating uncertainty associated with older terminations is too large to allow phase relationships to be determined.

Although the most advanced theoretical climate models still leave uncertainty, particularly about the sign and magnitudes of the effects, on GHG feedbacks, of some low - and high - clouds, a consensus began to develop that threats of resulting increases in global temperature — and the very large risks associated with their possible consequences — deserved substantial increase in attention.

Some key findings may be policy - relevant even though they are associated with large uncertainties.
