Sentences with phrase «decay rate from»

When the oceans begin to slow the rate of CO2 uptake at saturation point that will futher push atmospheric CO2 even higher, simultaneously the massive amounts of additional CO2 and methane and nitrous oxide etc released from the decay and oxidisation of oceanic living creatures who can not survive in a low ph environment will future ram the nail in the coffin.

So it is quite likely that plant photosynthesis (including that happening in the ocean from phytoplankton) could well be constrained by CO2 concentration at 280 ppmv, with a slightly higher input from animal respiration plus emissions from the Earth's interior balancing out the natural decay rate.

Was this «decay rate» offset in the past by slightly higher animal respiration than plant photosynthesis, plus unknown CO2 emissions from submarine volcanoes and fissures in Earth's crust?

Recent modeling work also points toward future collapse, even at reduced rates of warming and decay from the present (19).

The Hoyt & Schatten reconstruction used by Soon is not based on ANY measurements of solar radiation, but on [dubious] guess work extrapolated from solar activity proxies: «These indices are (1) the equatorial solar rotation rate, (2) the sunspot structure, the decay rate of individual sunspots, and the number of sunspots without umbrae, and (3) the length and decay rate of the sunspot cycle.»

In a linear system, the exchange rate controls the decay (recovery from impulse) rate — see my analysis at # 672.

The decay rate can be derived from the measured increase in volume and calculated outflow (s), which is a highly linear system, independent from the exchange rates or reservoir sizes.

Your analyses in # 672 is completely right, except for one point, the decay in mass from an impulse is not controlled by the exchange rate.

The IPCC uses several time constants: the constant for the exchange rate of ~ 8 years, and several time constants for the decay rates in different compartiments, ranging from less than a year (ocean surface) to decades (deep oceans) to centuries and millennia (rock weathering, sedimentation).

The «second order» review draft of the SPM for the Working Group II volume said «If current warming rates are maintained Himalayan glaciers could decay at very rapid rates, shrinking from the present 500,000 km2 to 100,000 km2 by the 2030s.»

If current warming rates are maintained, Himalayan glaciers could decay at very rapid rates, shrinking from the present 500,000 km2 to 100,000 km2 by the 2030s.

The water drawn from Shreveport gives a slower decay rate than does water from NYNY.

The oxygen content of the atmosphere is diminishing at a rate that corresponds to the increase in CO2, so the increase in CO2 is due to oxidation of carbonaceuos material of some kind, eg., burning, decay, etc., and not from, say, the oceans, volcanoes or some other geological process.

While lots of carbon cycles in and out of the atmosphere from photosynthesis and decay (most of that 95 % figure), the planet has a (comparably) very slow rate of removing carbon from the atmosphere and oceans for geological timescales — only enough to roughly cancel out volcanoes and other proportionally very small «old carbon» sources.

# 146 — From Global Climate Change and Agricultural Production «Temperature effects on the rates of biochemical reactions may be modelled as the product of two functions, an exponentially increasing rate of the forward reaction and an exponential decay resulting from enzyme denaturation as temperatures increase (FigurFrom Global Climate Change and Agricultural Production «Temperature effects on the rates of biochemical reactions may be modelled as the product of two functions, an exponentially increasing rate of the forward reaction and an exponential decay resulting from enzyme denaturation as temperatures increase (Figurfrom enzyme denaturation as temperatures increase (Figure 6.

Tabulate the CO2 exhalation rates over the last 15,000 years from (i) terrestrial and submarine volcanism (including maars, gas vents, geysers and springs) and calc - silicate mineral formation, and (ii) CH4 oxidation to CO2 derived from CH4 exhalation by terrestrial and submarine volcanism, natural hydrocarbon leakage from sediments and sedimentary rocks, methane hydrates, soils, microbiological decay of plant material, arthropods, ruminants and terrestrial methanogenic bacteria to a depth of 4 km.
