Sentences with phrase «positive effects of carbon dioxide»

In fact, the report staunchly defends positive effects of carbon dioxide.

Going forward, Wang said, the positive effect of carbon dioxide - induced water savings may eventually be offset by the negative effect of carbon dioxide - induced temperature increases when the temperature increase crosses a certain threshold.

Not exact matches

In most cases, the surcharges were initially met with hostility, but the positive effects have been hard to deny: Immediately following the initiation of zone charging, London saw congestion reduced by a quarter, average speeds increase by 30 percent, and carbon dioxide emissions decrease by 20 percent, per the Fix NYC report.

The theory of dangerous climate change is based not just on carbon dioxide warming but on positive and negative feedback effects from water vapor and phenomena such as clouds and airborne aerosols from coal burning.

U.S. Department of Agriculture data tables provide evidence for the importance of the eight Midwest states for U.S. agricultural production.3 Evidence for the effect of future elevated carbon dioxide concentrations on crop yields is based on scores of greenhouse and field experiments that show a strong fertilization response for C3 plants such as soybeans and wheat and a positive but not as strong a response for C4 plants such as corn.

``... the positive effects of elevated carbon dioxide on plant growth are well established experimentally and theoretically.

They have, in effect, caused a positive feedback loop: the more soil is exposed to sunlight as a result of trees burning, the speedier the decomposition process and the more carbon dioxide is released.

Regardless, climate models are made interesting by the inclusion of «positive feedbacks» (multiplier effects) so that a small temperature increment expected from increasing atmospheric carbon dioxide invokes large increases in water vapor, which seem to produce exponential rather than logarithmic temperature response in the models.
