Sentences with phrase «already accumulated in the atmosphere»

With the greenhouse gases already accumulated in the atmosphere, it would take less than 30 years for it to be inevitable that temperature would in time reach 2 °C above the pre-industrial level if the global greenhouse - gas emissions stayed at their current rate.

Not exact matches

So the only carbon used would be that which already existed above the surface; it could no longer dangerously accumulate in the atmosphere.

Cuts would constitute the nation's first restrictions on carbon dioxide, a gas that has no direct effect on human health — in fact, it is the bubbles in beer — but that many scientists have concluded is already altering ecosystems and weather patterns as it accumulates in the atmosphere.

However, while displacing all fossil fuel power plants with solar and wind farms is necessary in curbing the flow of additional greenhouse gases into our atmosphere, it does nothing to capture the prevailing stock of greenhouse gases that has already accumulated.

Clearly we are already in trouble and need to stop accumulating carbon in the atmosphere as soon as possible.

The fraction of aCO2 in the atmosphere is already about 9 %, partly because the human fraction of the inputs did grow to 5 % (8/150 GtC) over time, partly because it accumulates over 5 years, as only 20 % of all CO2 is exchanged per year, thus also only 20 % of the aCO2, but only the deep oceans exchange it with aCO2 free fresh deep ocean natural CO2, while ocean surface and vegetation give some aCO2 back in the next season.

So there is another reason to believe that while humans certainly ARE adding CO2 to the atmosphere, it isn't the primary component (we already know it isn't the primary component because the atmosphere is accumulating CO2 at a much faster rate than humans add each year) because while human emissions have been rising nearly exponentially, atmospheric CO2 has been rising linearly and that rate of rise did not change when global human CO2 emissions fell in absolute terms (tons of CO2 emitted to atmosphere fell in 2009, rate of increase of atmospheric CO2 unchanged).
