Sentences with phrase «significantly change the concentration»

This means that even a small change in pH can significantly change the concentration of H + ions in seawater.

So, if your argument is that we know we are significantly changing the concentration of a major gas that impacts the temperature of the earth's surface, and you hold that all of our attempts to project how seriously this will impact us are useless, then we really need to ratchet back our use of fossil fuels quicker and more radically since in your world, the impacts may be much WORSE then the computer models.

Not exact matches

But at pressures found between those two depths, bridgmanite undergoes chemical changes that end up significantly lowering the concentration of iron it contains.

Moreover, a cell culture constantly alters its own environment — changing the concentration of oxygen, carbon dioxide and nutrients significantly over time.

By this time, atmospheric CO2 concentration will probably have become sufficiently high (and we will be committed to further increases) that a climatic change significantly larger than any which has occurred in the past century could be unavoidable.»

One study that focused specifically on the relationship between exercise intensity and BDNF concentration levels found no significant changes in BDNF levels after the low - intensity exercise, but significantly elevated BDNF levels after high - intensity exercise.13 Ferris, L.T., et al. «The Effect of Burst Exercise on Serum Brain - Derived Neurotrophic Factor Levels and Cognitive Function,» Medicine and... continue

However it is unlikely that the past atmospheric concentrations would have led to a significantly lower pH in the oceans, as the rate at which atmospheric CO2 changed in the past was much slower compared with the modern day.

Can you describe very specific changes in bacterial mass and metabolism that over the course of a century would not only significantly increase atmospheric CO2 concentration but also increase the ratios of C12 to C13 and C14 in the manner that has been observed (we'll leave out the bookkeeping from industrial records that also must be accounted for)?

From 1870 to 2015, the CO2 concentration in the atmosphere increased significantly, said Professor Maria Sanz, scientific director at the Basque Center for Climate Change in a recent webinar organized by WWF Forest and Climate.

Given that CO2 has such a major role in the natural greenhouse effect, it makes intuitive sense that changes in its concentration because of human activities might significantly enhance the greenhouse effect.

Importantly, the scientists recognize that «atmospheric growth rates have deviated significantly from predictions of a linear model of atmospheric CO2 concentrations and anthropogenic emissions since 2002,» underscoring the imprecision of computer models for predicting climate change.

Despite a half century of climate change that has significantly affected temperature and precipitation patterns and has already had widespread ecological and hydrological impacts, and despite a near certainty that the United States will experience at least as much climate change in the coming decades, just as a result of the current atmospheric concentrations of greenhouse gases, those organizations in the public and private sectors that are most at risk, that are making long - term investments and commitments, and that have the planning, forecasting and institutional capacity to adapt, have not yet done so.

It is also because there is much more water vapor in the atmosphere than CO2 and, since the amount of climate forcing goes approximately logarithmically with concentration that means the concentration of water vapor has to change by a significantly larger ABSOLUTE amount to produce the same effect.

The juiciest disaster - movie scenario would be a release of enough methane to significantly change the atmospheric concentration, on a time scale that is fast compared with the lifetime of methane.
