Sentences with phrase «smaller concentrations so»

For example, the direct radiative effect of a mass of methane is about 84 times stronger than the same mass of carbon dioxide over a 20 - year time frame [22] but it is present in much smaller concentrations so that its total direct radiative effect is smaller, in part due to its shorter atmospheric lifetime.

However, the resolution of the LEND instrument is greater than the size of most PFS, so smaller PFS slopes, perhaps approaching yards in size, may have significantly higher abundances, and indications are that the greatest hydrogen concentrations are within the permanently shaded regions, according to McClanahan.

It seemed so obvious that if fairly small changes in development, which adjusted the timing and concentrations of growth and signaling factors, could have led to the evolution of birds from nonavian dinosaurs, we could readjust those changes in development and get a dinosaur from a chick embryo.

It's very difficult to detect these nanomaterials in the environment since the concentrations are so low and the particles so small.

So Weschler and Wisthaler simulated a typical office environment at the Technical University of Denmark in Copenhagen — two people in a carpeted 28.5 — cubic meter room at a temperature of 23 degrees Celsius with two small stainless steel tables, two chairs, two flat - screen LCD monitors, two headsets, one walkie - talkie, one small mixing fan, a few books, two laptops, two bottles of water and ozone concentrations that reached roughly 32 parts per billion, an average exposure for a hot, smoggy day.

But because the concentrations that affected the animals were so small — 30 times lower than the current allowable limit in drinking water — the findings support the use of amphibians as environmental sentinels.

You can set a dial feature for the ppm you want, and you get mostly ionic - silver as opposed to nano - size particulate colloidal silver clumps (agglomerations), but even those will be so small because the SilverGen does not make the clumps large enough that it turns the distilled water yellow, this being due to it's automatic shut off feature for the ppm concentration you select using the dial setting.

Some also claim that it absorbs more efficiently and results in greater creatine muscle concentration than monohydrate, so the dose can be smaller.

So you get that concentration of power in a relatively small number of big publishers and bookstore chains.

Though many dogs can stomach small amounts of cheese or yogurt without incident, milk has higher concentrations of lactose, so it takes a far smaller serving to cause problems.

The xylitol concentration is low enough that it shouldn't be a concern so long as portions are limited, but if your small dog consumes too many berries behind your back, keep an eye on him.

Small breeds also tend to live longer than larger breeds, so having a dog food with a high concentration of antioxidants can help to prevent any free radical damage that may occur as your miniature or teacup Yorkie ages.

Here, the concentration of nutrients and the resultant populations of smaller fish is so great as to sustain shoals of larger fish which feed on them.

He does not, however, address the size and bias of the approximation errors with respect to a small change (1 % or less of mean temp in Kelvin) resulting on Earth from a small change in forcing (doubling of CO2 concentration), over a long but finite time (140 years or so for the concentration of CO2 to double from what it is now.)

The concentration of HCO3 — goes up a bit, but there is so much HCO3 — that the relative change in HCO3 — is smaller than the changes are for CO2 and CO32 -.

Climate neutralises these small factors, however, so even, say a 0.02 % decrease in CO2 concentration can be easily dealt with in climate models.

[Response: A small new source is swamped by larger already existing sources, so the relative change in the atmospheric concentration is relatively small.

So even doubling the concentration of atmospheric carbon dioxide would only result in a very small theoretical rise in temperature, since the largest amount of the greenhouse effect caused by atmospheric CO2 has already occurred with the first 20 ppmv concentration.

The process of breaking big rocks into smaller ones releases more minerals and chemicals so the water below valley fills contains higher concentrations of selenium

Because this reduction in CO2 concentration was so small, the warming abated over the 10 - year period of the tax would be just 0.000085 C °, at a discounted cost of $ 130 billion over the ten - year term.

Because this fraction was so small, the projected CO2 concentration of 412 ppmv that would otherwise obtain in the atmosphere by 2020 would fall to 411.987 ppmv.

Methane that escapes the sea is generally a small fraction of methane that is released from clathrates at the sea floor, though if the concentration rose high enough so much could make it to the atmosphere that the impact of methane as a GHG in air (before it devolves to CO2 in air) overwhelmed the negative effects of methane decomposing to CO2 in the oceans..

Reading just that people might easily be led to believe that because human carbon dioxide emissions are so small, they won't be noticed against the background noise of natural exchanges, when that is patently untrue with CO2 concentrations stable within a few ppm around 280 ppm for the last few thousand years until mass fossil fuel burning started.

Thus if the concentration of carbon dioxide doubles there is relatively smaller effect in moister regions than in the dryer regions so the temperature effect of the increased carbon dioxide is greater in the dryer regions.

Over time, the small annual increases have raised the atmospheric concentration of CO2 by around 35 % or so.

Good explanation — but only if the concentration of the greenhouse gas is vanishingly small so that it's absorption of the infrared is near zero.

From there, Bayesian approaches to «small area estimation»; detection of small concentrations; Bayesian time series and hierarchical models, and so on.

Wayne, Robert Stevenson and others have made the point that, given current concentrations of CO2 and H2O and other so - called «greenhouse gases», the first - generation photons from the Surface up into the Atmosphere are absorbed to extinction in 120 meters or some other relatively small distance compared to the total height of the Atmosphere.

Many fluorinated gases have very high global warming potentials (GWPs) relative to other greenhouse gases, so small atmospheric concentrations can have proportionately large effects on global temperatures.

The growth is measured in total livestock numbers — so although the number of livestock farms in the U.S. has actually decreased, according to Food & Water Watch, the number of livestock has increased, which means the industry has continued on its path away from small - scale farming and toward a monopoly - like concentration.

The AGW proponents realize that on its own, increasing CO2 concentrations are not going to make a huge difference, so they have to include other factors to multiply the effect a small temperature increase due to increasing CO2.
