Sentences with phrase «ocean uptake»

In other words, is the larger - than - earlier - thought increase in atmospheric temperatures occurring in tandem with the natural variation in ocean uptake during the last decade or so?

Changes in upper - ocean biological productivity could also enhance or inhibit ocean uptake.

The excess CO2 we put into the atmosphere by burning fossil fuels such as coal, oil, or natural gas is removed very slowly by ocean uptake and other geological processes.

Warming tends to reduce terrestrial ecosystem and ocean uptake of atmospheric CO2, increasing the fraction of anthropogenic emissions that remains in the atmosphere.

Changes in ocean circulation could either enhance or inhibit ocean uptake.

Here is their difficulty: If they invoke the deep ocean uptake of heat (without proof) this looks like handwaving but also means that the time to equilibrium could be very long such that the next 100 years is governed by the transient sensitivity not the equilibrium value.

• Accelerated warming because of decreased ocean uptake of CO2 from atmosphere by phytoplankton and CFCs acting as greenhouse gases

But, we have explanation for the «pause» ranging from reduction in solar activity, increase ocean uptake, CFC curtailment and Chinese aerosol.

From the formula, we can see that the carbon footprint area is essentially calculated by dividing total anthropogenic carbon emissions remaining after accounting for ocean uptake (i.e., 72 % of net human emissions) by the rate at which existing forests sequester carbon.

There's typically an initial ocean uptake as tropical East Pacific upwelling (CO2 degassing) is reduced, followed by a stronger release of carbon from land.

On still longer time scales, acidification by the invading CO2 dissolves carbonate sediments on the sea floor, which further enhances ocean uptake.

Langenfelds et al. (1999) and Battle et al. (2000) have shown that recently estimated values for the disequilibrium terms lead to consistency between the partitioning of CO2 uptake into land and ocean uptake based on O2 and on d13C measurements.

The inferred ocean uptake pattern shows the sum of two components: the natural carbon cycle in which CO2 is outgassed in the tropics and taken up in the extratropics, and the perturbation uptake of anthropogenic CO2.

Climate change increases the fraction of emissions that remain airborne by suppressing ocean uptake, enhancing soil respiration and reducing plant NPP.

Air Pollution and Materials • Increased acid deposition • Increased photochemical smog • Degradation of outdoor paints and plastics Fig, p. 488 Global Warming • Accelerated warming because of decreased ocean uptake of CO2 from atmosphere by phytoplankton and CFCs acting as greenhouse gases

E.g., given that the net radiative balance at the top of the atmosphere remains negative, which certainly indicates continued warming, Trenberth's studies suggest deep ocean uptake of most of the recent heating.

This states that the variability of fossil fuel emissions and estimated variability in net ocean uptake are too small to account for this signal and is therefore thought to be due to year - to - year fluctuations in the land - atmosphere fluxes.

Remember, more than 90 percent of human induced planetary warming goes into the oceans, while only 2 percent goes into the atmosphere, so small changes in ocean uptake can have huge impact on surface temperatures.

The centre runs research programmes in climate variability and change, the monitoring of sea levels, ocean uptake of carbon dioxide, and Antarctic marine ecosystems.

[Response: I'm sure Eric won't mind me stepping in with some questions for you instead — 1) why do you keep insinuating that terrestrial and ocean uptake of anthropogenic CO2 is somehow not accepted by mainstream scientists?

The ocean uptake physics are governed by ocean circulation, which we know a lot about by measuring the carbon - 14 distribution in the ocean.

As to ocean uptake of heat, the novice might ask, «how come that didn't happen so obviously a in the past?

When your model neglects the Calcium Carbonate processes and silicate weathering, it predicts that there will be * NO * change in atmospheric CO2 after the ~ 300y ocean uptake is complete.

Cumulative land and ocean uptake of carbon for the period 1850 - 2005.

Suess (1955); the ocean uptake question was raised especially by measurements of carbon - 14 in sea shells.

Prior to reaching the target, 4.5 W m − 2, cost minimization requires that the greenhouse gas emissions price rise at the interest rate, adjusted by the rate of ocean uptake (Edmonds et al. 2008; Clarke et al. 2007; Hotelling 1931; Peck and Wan 1996).

In addition, warming tends to reduce land and ocean uptake of atmospheric CO2, increasing the amount of human - induced emissions that remains in the atmosphere

A global Biogeochemical - Argo array would enable direct observation of the seasonal to decadal - scale variability in net community production (the rate at which life - forms capture and store chemical energy as biomass), the supply of essential plant nutrients transported from deep waters to the sunlit surface layer, ocean acidification, hypoxia (low oxygen levels), and ocean uptake of carbon dioxide.

If nothing else there will always be Milankevich cycles, ocean uptake, and the Urey reaction.
