Sentences with phrase «green plant growth rates»

That 1.1 C is the IPCC low end «sensitivity» estimate which isn't a scary number at all and in fact is a great number because if that's all it is then the slight warming, mostly in the winter in the higher latitudes, is a great boon to agriculture especially when the biological effect of higher CO2 on green plant growth rates and water consumption is taken into consideration.

It's baloney of course — the current climate is the best climate our planet has had in at least 500 years for human health and prosperity, and green plant growth rates.

Not exact matches

The researchers believe the greening is a response to higher atmospheric carbon dioxide inducing decreases in plant stomatal conductance — the measure of the rate of passage of carbon dioxide entering, or water vapor exiting, through the stomata of a leaf — and increases in soil water, thus enhancing vegetation growth.

Mander, a chemist from the Australian National University in Canberra, has developed a version of a plant growth hormone which keeps grass lush and green but slows its growth to about a third of its normal rate.

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.»

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.
