Sentences with phrase «in plant growth rates»

The missing variable fallacy of neglecting a factor entirely, implicitly treating it as 0 % effect, minimizing mention to quickly skip on (except when the target audience unavoidably already has heard of it), is common when something is so extraordinarily dangerous to the CAGW movement as to be he - who - must - not - be-named to them, a distinction which belongs to the magnitude of beneficial effects of CO2 (several tens of percent rise in plant growth rates under a more extreme scenario of CO2 doubling, plus as huge a rise in water usage efficiency, if the plants aren't underfertilized meanwhile) and to the dominating influence of cosmic rays on climate as in the link in my name.

Early evidence suggests that globally, the rate of water loss from soil and plants (called «evapotranspiration») has declined, a finding reinforced by a global slowdown in plant growth.

The CO2 produced does, however, accelerate the growth rates of plants and also permits plants to grow in drier regions.

But even without warming, an increase in carbon dioxide should itself accelerate growth rates of plants.

The inescapable if unfashionable conclusion is that the human use of fossil fuels has been causing the greening of the planet in three separate ways: first, by displacing firewood as a fuel; second, by warming the climate; and third, by raising carbon dioxide levels, which raise plant growth rates.

This greater plant growth means more carbon is stored in the increasing biomass, so it was previously thought the greening would result in more carbon dioxide being taken up from the atmosphere, thus helping to reduce the rate of global warming.

And it's happening because of carbon dioxide and global warming: «human use of fossil fuels has been causing the greening of the planet in three separate ways: first, by displacing firewood as a fuel; second, by warming the climate; and third, by raising carbon dioxide levels, which raise plant growth rates.»

There are two primary externalities that result from our emissions of carbon dioxide into the atmosphere — 1) an enhancement of the greenhouse effect, which results in an alteration of the energy flow in the earth's climate and a general tendency to warm the global average surface temperature, and 2) an enhancement of the rate of photosynthesis in plants and a general tendency to result in more efficient growth and an overall healthier condition of vegetation (including crops).

Aerial CO2 fertilization is the reason for the increase in plant growth, crop yield, and presumably tree growth for the recent past, where some trees grow at faster rates than others by increasing airborne carbon dioxide concentrations.

The basic physics of greenhouse gases are simply not one of those things that are not well - enough understood and if you don't understand how greenhouse gases work you can't possibly move on to any reasonable debate about other phenomena which can and do (IMO) largely negate the effects of increasing greenhouse gases and leave us in a situation where the modest increase in carbon dioxide has vast beneficial effect by warming the planet at high latitudes where warming is welcome, not warming it at low latitudes where it is already warm enough, increasing the growth rate of green plants, and decreasing the water needs of green plants at the same time.
