Sentences with phrase «long timescales»

We had written about it the year before, in one of the first papers on the divergence problem — I think other groups had actually called it the divergence problem — and, since then, we have been working with other tree ring data trying to improve the way we process the data to try and make sure we keep as much of the low frequency information on longer timescales in the trees because you have to standardise trees in a certain way to produce temperature reconstructions.

But a lot more research will have to be done before we can be sure these positive effects persist and outweigh any negative ones over the very long timescales involved in storing radioactive waste.

When the project started, we mostly ran global models looking at long timescales of decades, but more recently we have been running regional models looking at much shorter time periods of months to a few years as part of our weather@home series of experiments.

Thus it can retain evidence for long timescale variability.

Unlike Charney climate sensitivity, which is related to the strength of feedbacks involving short timescale climate processes such as those involving clouds and water vapor, Earth System sensitivity also integrates feedbacks involving long timescale changes in the cryosphere, terrestrial vegetation, and deep ocean circulation.

The Decadal Climate Prediction Project addresses a range of scientific issues involving the ability of the climate system to be predicted on annual to decadal timescales, the skill that is currently and potentially available, the mechanisms involved in long timescale variability, and the production of forecasts of benefit to both science and society

That's true, but they fail to express the much longer timescales involved.

«Our results indicate that [Proxima Centauri b] and similar exoplanets are generally not capable of supporting an atmosphere over sufficiently long timescales when the stellar wind pressure is high,» Dong said.

We often think of this process as being so long timescale that its not a factor, but I'm not convinced that this assumptions holds up for the rapid and dramatic high - latitude warming of the past century.

Observations alone are too sparse in the oceans to describe and understand decadal and longer timescale variations in the ocean circulation and hence ocean heat uptake.

These problems occur on almost inconceivably longer timescales: the sun will be stable for hundreds of millions to billions of years; the dinosaurs died 66 million years ago.

Longer timescales bring changes in vegetation that also affect heat absorption, and the possibility that land and oceans begin to release CO2 rather than absorb it.

Until now, changes in the relative proportion of rare mutations, that could be both detrimental and adaptive, had only been shown over relatively long timescales, by comparing African and European populations.

Climatologists, who study longer timescales and are used to working with incomplete records, have more faith in the data, yet know less about the day - to - day dynamics of hurricanes.

«The main ingredients for this phenomenon,» de Ruiter says, «are the interplay between short timescale fluid dynamics, which set the adhesion, and longer timescale thermal effects, which lead to global deformation.»

Collisions take place over very long timescales compared to the length of our lifetime — several tens of millions of years.

Short timescale genes shape development and long timescale genes manage the cellular machinery.»

But it takes some time for the model systems to reach the new equilibrium state, because some of the feedbacks in the system (e.g., heat absorption as the ocean circulates) operate on fairly long timescales.

This relates to a change in overall long timescale temperature variability.

Nature: The vagaries of South Asian summer monsoon rainfall on short and long timescales impact the lives of more than one billion people.

On extremely long timescales of hundreds of millions of years, the output of the sun has changed significantly; this is of no urgent concern on human timescales.

An underlying manifestation from evolutionary processes fits well with the evidential long timescales noted in section 3.

Good quality proxy data are accurate and can reconstruct long timescales but are collected from limited locations and may not have broad geographic relevance; translating measurements from proxy data into useful climate variables (such as temperature and precipitation) may also be difficult.

The setting of rock weathering thermostat is influenced, on still longer timescale of My, the plate techtonics.

Prof Seralini said the results showed that genetic modification needed to be studied far more carefully than at present and over far longer timescales.

As the species» population grows and its energy harvesting intensifies, for example, the composition of the planet and its atmosphere may become altered for long timescales.

(The actual equilibrium takes on the order of a few thousand years, the mixing time of the oceans, to reach... But that's at constant temperature... So if the oceans warm significantly, then we lock in a new equilibrium, at higher atmospheric CO2 for much longer timescales.)

, economists who study climate change are inclined to choose lower discount rates because of the inter-generational transfers and long timescales associated with climate change.

Simulating such long timescales would take too much computation time with just conventional approaches.
