Sentences with phrase «burning gigatons»

Not exact matches

We humans emitted 35.9 metric gigatons of carbon dioxide into the atmosphere in 2014, mostly from burning coal and natural gas in power plants, making fertilizer and cement, and other industrial processes.

That molecule — released by the gigaton from human activities like fossil fuel burning and clearing forests — causes the bulk of global warming.

But for the biggest companies, the figures are quite exact: If you burned everything in the inventories of Russia's Lukoil and America's ExxonMobil, for instance, which lead the list of oil and gas companies, each would release more than 40 gigatons of carbon dioxide into the atmosphere.

An even shorter version is: It is getting warmer; CO2 is a greenhouse gas and so an increase in it will drive warming (logarithmically without feedbacks); we are taking many gigatons of C out of the earth and dumping it into the biosphere as CO2; the increase in CO2 and the change of isotopes in the C are consistent with the source being the fossil fuels we are burning.

There are enormous assumptions in most calculations, including the assumption that «carbon negative» technologies, like capturing CO2 from power plants burning biomass, can be done at a scale remotely relevant to the climate problem (to be relevant one needs to be talking in gigatons of avoided CO2 emissions per year — each a billion tons).

The ocean, with around 38,000 gigatons (Gt) of carbon (1 gigaton = 1 billion tons), contains 16 times as much carbon as the terrestrial biosphere, that is all plant and the underlying soils on our planet, and around 60 times as much as the pre-industrial atmosphere, i.e., at a time before people began to drastically alter the atmospheric CO2 content by the increased burning of coal, oil and gas.

But, that doesn't mean we need energy that comes from buried hydrocarbons that, when burned, spew gigatons of greenhouse gas into the atmosphere.

So climate modelling may not be perfect in the timing, but the end result would still be the same level of temperatures around 2100, so therefore we don't have any room to think emissions can continue at present levels, and the amount of carbon left to burn would not be as high as 800 gigatons.

If all of the currently available carbon resources — estimated to be around 10,000 gigatons — were burned, the Antarctic Ice Sheet would melt entirely and trigger a global sea - level rise of more than 50 meters, a new long - term modeling study suggests.

Humans have been burning about 7 gigatons of carbon per year (average of last 10 years.

The sink swallowed up roughly 0.77 gigaton of carbon per year, persisting despite a significant increase in biomass burning emissions that occurred during the dry season of 2011, fueled by the rapid growth of vegetation that year.

If public policy shifts to something closer to the 1,000 gigaton budget, there would be a lot of stranded assets and investors would get burned, as the fossil fuels would not.

About 3100 gigatons of CO2 is in the atmosphere — all fossil fuel reserves burned to the last erg would add about 2795 gigatons.

We talk about warming in terms of degrees Celsius and gigatons of carbon burned.

For continued fossil fuel burning would be enough to force a release of Arctic carbon stores equal to 35 % or more of the human annual emission, or about 3.5 to 4 gigatons of carbon each year.

The problem, 350.org says, is that fossil fuel companies have another 2,795 gigatons in their reserves that they want to burn.

and (4) that 9 Gigatons of carbon (coal, gas, oil) are being burned each year (by us humans).

You state he writes, «We have already burned through about 2,000 Gigatons, ie, we have expended two thirds of our apparent «carbon budget.»

Yet, Mann writes, «We've already burned through about 2,000 Gigatons, i.e. we have expended two thirds of our apparent

But on that last, we've burnt about 321 Gigatons carbon since 1751.

We're talking about a massive upscaling of wood burning, as much as 9 gigatons a year.

Humans emit gigatons of water vapor, by burning hydrocarbons, and it doesn't affect atmospheric H2O, because it's condensable.

What we do know (consensus) is 6.2 Gigatons of carbon are introduced into the atmosphere by the burning of fossil fuels (and production of cement) annually.

«The burning of fossil fuels sends about seven gigatons of CO2 per year into the atmosphere, which sounds like a lot.
