Sentences with phrase «given certain temperature»

Not exact matches

We know approximately how much of certain atoms must be made in a given type of star, says Mac Low, but lab - based experiments could help nail down exact numbers under various conditions, such as changing temperatures or plasma density.

«Because different plants grow at different temperatures, we can constrain what the temperatures were in a given place at a certain time.»

From the macroscopic standpoint, superconductivity is a property of certain materials that, when cooled below a given temperature, conduct electricity without any energy loss — i.e., with zero electrical resistance.

The computer monitors the warm up cycle of your engine — it looks for your coolant temperature to rise to a certain level within a given time frame.

The climate change in this period is generally believed to be associated with precessional changes in the distribution of solar radiation, which primarily affect land - sea temperature contrast, and give only a regional warming, plus an enhancement of certain monsoonal circulations.

Given that 1985 was the last year with temperatures below the 20th century average, and 2000 - 2010 was the hottest decade on record, it has become impossible to say for certain that any given storm is free from the influence of our warmed wGiven that 1985 was the last year with temperatures below the 20th century average, and 2000 - 2010 was the hottest decade on record, it has become impossible to say for certain that any given storm is free from the influence of our warmed wgiven storm is free from the influence of our warmed world.

Given all these measurement issues / fiddles / errors / uncertainties, how certain can we really be that the putative temperature rise is real, anthropogenic or not?

It's not very good for saying «in 2050, the temperature will be X», but it is useful for determining what range the average temperature is likely to be within over, say, a 30 - year period centered on the date in question (with much uncertainty) given certain starting conditions and certain inputs and changes in forcing over time, and.

A given amount of radiant energy, say 1000 watts per square meter, can only heat the molecular structure of solids and liquids to certain level of heat [which measured as temperature].

You may notice 60 K is different from the value often given according to certain theoretical calculations: 33 K. I am curious what the same calculations would suggest for the temperature of the moon, supposing it had an atmosphere with the same composition and surface pressure as found here.

Even worse, it is actually misleading to say the world is heading for 3.5 °C of warming, or 3.0 °C or 4.0 °C, because to do so gives the impression that we can set the global thermostat at a certain temperature, whereas beyond a certain amount of warming (maybe 2.0 °C although scientists do not really know) feedback mechanisms will be set in train that will amplify human - induced warming and take the Earth to a warmer, perhaps much warmer, state.

Another interpretation is that given a certain energy imbalance at the top of atmosphere, if the heat is not manifested as surface temperature rise then it goes elsewhere.

Given a planet with a certain albedo, a certain distance from a star of a given luminosity, one can determine what the average temperature of the planet would be in the absence of a greenhouse efGiven a planet with a certain albedo, a certain distance from a star of a given luminosity, one can determine what the average temperature of the planet would be in the absence of a greenhouse efgiven luminosity, one can determine what the average temperature of the planet would be in the absence of a greenhouse effect.

The reason given in Briffa 2001 for their selection of a certain reconstruction is discussed: >> > The selection of a single reconstruction of the ALL temperature series is clearly somewhat arbitrary... The method that produces the best fit in the calibration period is principal component regression... << >> ``... we note that the 1450s were much cooler in all of the other (i.e., not PCA regression) methods of producing this curve...» << <

The reason because those longer cycles have not been included in the present model is because their amplitude is not certain given to the fact that the temperature records start in 1850.

«Sure, it's possible that we will fail to stabilize temperatures below 2C warming even given concerted efforts to lower our carbon emissions, but simply discarding this goal would make failure almost certain,» he said via email.

Given that said (CO2) emissions are much more certain to benefit food supplies than they are to influence climate and / or temperatures, reduction seems like a perverse and foolish option.

While these uncertainties prevent the establishment of a high - confidence, one - to - one linkage between atmospheric greenhouse gas concentrations and global mean temperature increase, probabilistic analyses can assign a subjective probability of exceeding certain temperature thresholds for given emissions scenarios or concentration targets (e.g., Meinshausen, 2005; Harvey, 2007).

Re 416 Bernd Herd — in climate science, for global climate change, specifically a global (average surface) temperature change in response to a global (typically average net tropopause - level after stratospheric adjustment) radiative forcing (or other heat source — although on Earth those tend not to be so big), where the radiative forcing may be in units of W / m ^ 2, so that equilibrium climate sensitivity is in K * m ^ 2 / W (it is often expressed as K / doubling CO2 as doubling CO2 has a certain amount of radiative forcing for given conditions).

It's all fairly basic — there's no conditional triggers, for instance, like having the Echo Plus run Routines based on motion sensors being activated or if the temperature drops below a certain level, and you can't have specific songs or playlists played — but should give those new to automation a taste of what's possible.
