Re # 53: First off, it is unclear whether CO2 is the limiting factor for plant growth (particularly now).

Not exact matches

However, the changes in climatic conditions arising from climate change could represent a far more important factor here: i.e. temperatures that increasingly exceed the optimum level for plant growth, like those experienced this summer, shifts in the vegetation periods, and more frequent droughts.

The paper is «solid, exciting research,» says ecologist Chris Field of Carnegie Institution for Science in Palo Alto, California, who notes that various models have looked at ways different factors might affect future plant growth.

sprouts are more chemically complex because the plant is a little chemical factory producing an ever changing set of growth factors essential for the formation of all the parts of a plant which will change through out it's life cycle as it reaches it «s ultimate goal of self repoduction.

Zinc was very attractive to me because of earlier studies showing that it was a growth factor for microorganisms, for plants and for animals.

Since sterols are animal growth factors and phytosterols and plant growth factors which we, as animals don't particularly respond to, I would think that the (animal) sterols would set us up for cancer simply by virtue of the fact that as growth factors, they would promote growth of tumors.

Indeed, unlike animal protein, plant protein has not been associated with increased insulinlike growth factor 1 levels28, 29 and has been linked to lower blood pressure,30 - 32 reduced low - density lipoprotein levels,32 - 34 and improved insulin sensitivity.35 Substitution of plant protein for animal protein has been related to a lower incidence of CVD36 - 39 and type 2 diabetes.40 - 42 Moreover, although a high intake of red meat, particularly processed red meat, has been associated with increased mortality in a recent meta - analysis of 13 cohort studies, 43 high consumption of nuts, a major contributor to plant protein, has been associated lower CVD and all - cause mortality.44 These results underscore the importance of protein sources for risk assessment and suggest that other components in protein - rich foods (eg, sodium, 45 nitrates, and nitrites46 in processed red meat), in addition to protein per se, may have a critical health effect.

The word puvidham loosely translates from Tamil as «love for the earth,» and children learn much of their academics through organic farming, including math (establishing planting patterns), biology (studying the relationships between plant growth and environmental factors), economics (determining the price of a farm product), and language skills (writing about their activities and observations).

In addition, Ridley did not make it clear that Myneni had suggested that 42 % of the 14 % increase in annual productivity «can be attributed to relaxation of climatic constraints to plant growth,» with «57 % to other «anthropogenic factors»,» whereas the paper published in the journal «Nature Climate Change» in April 2016 did not present a figure for annual productivity, instead concluding that 25 % to 50 % of the Earth's vegetated area had greened, with about 70 % of this trend attributable to carbon dioxide fertilization.

I would not have expected this to be the case as the decomposition process involves oxidation reactions that are exponential functions of temperature while the alarmists have been been arguing for years that the plant growth process is limited by, and dependent on, factors other than just temperature.

Having been raised in a family which once owned America's largest independent dairy, I'd like to think I know something about plants and trees, so I am always puzzled when someone says temperature exerts the primary control, because different factors are all major contributors to plant / tree growth, water availability arguably being the most important factor facilitating nutrient uptake for a given non-extreme area.
