More plant growth could slow global warming: NASA
(AFP) – 7 hours ago
WASHINGTON — In a world with twice as much carbon dioxide in the atmosphere, plants could grow larger and create a cooling effect on a warming globe, but could not halt or reverse climate change, NASA said Tuesday.
One of the main mysteries scientists face with climate change is how to project it over time, particularly how to account for Earth’s reaction to warmer temperatures, a phenomenon known as “feedback.”
It has long been known that plants — which use carbon dioxide, sun and water to grow through the process of photosynthesis — are able to adapt to higher carbon dioxide levels by using nutrients more efficiently and growing bigger leaves.
“The process is called ‘down-regulation.’ This more efficient use of water and nutrients has been observed in experimental studies and can ultimately lead to increased leaf growth,” NASA said in a statement.
But just what effect that increased plant growth would have on global warming has been difficult to predict.
Time for another $1billion to check if CO2 is used by plants?
When is Coke going to be in trouble, all those bottles of coke opened all over the world, must emit more CO2 then my car?
Coke gets a pass because they use a polar bear in their commercials.
I have been keeping planted fish tanks for years, and injecting CO2 in to the water with amazing results. Growth rate can increase by x 10, but all the other nutrients need to be increased too. The system for dosing the water is called Estimative Index.
Pollutant my arse!
They are on the cutting edge. Maybe the moon landing really was staged.

Staging the moon landing would require more intelligence than determining that plants use CO2 to live
lol, yeh I saw that at WUWT. We should all welcome NASA to the 21st century. They’re catching up! Only a few years behind skeptics.
AAM, I’m starting to think they that maybe someone else landed on the moon and sent NASA pictures and film. Obviously, the brain trust they have today, I doubt they could float a boat from Fla to Texas.
But how could this study possibly be correct? It’s based on models! Right? We know the models can’t show us anything accurately.
A ridiculous post to make on a computer modeler’s web site.
The information provided above is very useful. Thanks.
