The first part is just the number 270. What it means is that if we go back in time by more than a few hundred years, the average CO2 concentration in the atmosphere would have been around 270 ppmv (compare that to today’s 390 ppmv !) The second part is responsible for the oscillation of the concentration due to seasons. 2021-04-08 Regarding `most of this rise is due to human activity' (taking CO 2 from 280 to 390 ppmv), the evidence is strong, though subject to minor uncertainties. The most important feature is the steady rise over the past century or two -- not the transient, short-term fluctuations that are inevitably superposed on it, such as the regular seasonal cycle and other transients impacting the biosphere. ambient value of 27.85‰ and 350 ppmv for plants growing in the open atmosphere and 28.0‰ and 390 ppmv for plants growing un-der a closed canopy or in dense stands, re-spectively (Broadmeadow et al.

2020-08-17 · In 2010 the average concentration was 390 ppmv, and climatologists expect the concentration to rise to between 413 and 750 ppmv by 2100, depending on the level of greenhouse gas emissions. With additional CO 2 transferred to the oceans, pH would decline further; under worst-case scenarios, seawater pH would drop to between 7.8 and 7.9 by 2100. Numerous studies have addressed effects of rising atmospheric CO2 concentration on rice biomass production and yield but effects on crop water use are less well understood. Irrigated rice evapotranspiration (ET) is composed of floodwater evaporation and canopy transpiration.

Numerous studies have addressed effects of rising atmospheric CO2 concentration on rice biomass production and yield but effects on crop water use are less Climate Change Recent evidence suggests that the Earth, now passing 390 ppmv CO2 in the atmosphere, has already transgressed the planetary boundary and is approaching several Earth system thresholds.

With concentrations measured as ppmv the mass of the molecule is incorporated and the concentrations of two or more gases can be compared in molecular terms without any further calculations. of c. 390 or 750 ppmv pCO 2.
