Not exact matches

Assuming the same holds true for DISCOVER, ink would bring an additional 9.6 tons of CO2 to the emissions calculation.

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).

-- Mass balance calculations, however, indicate that co2 concentrations should be twice as high as they are given the known emissions and the long residence time, indicating a missing sink.

IPCC makes all sorts of calculations on the deleterious effects of NOT halting CO2 emissions, based on the same climate sensitivity estimate and a bunch of model «scenarios» on CO2 increase.

First you erroneously opine that my calculation of the impact of halting all human CO2 emissions by 2030 on the temperature in 2100 is based on a false premise.

Theoretician - climatologist on climate calculation: We can model our biosphere's chaotic climate systems with enough confidence to know we are heading for a «big problem» if we don't mitigate CO2 emissions.

On this page... Boiling water CO2 abatement calculation CO2 calculated from distance travelled CO2 calculated from electricity used CO2 calculated from fuel used CO2 per person for a range of cars Greenhouse emissions by transport type Technical data Top Useful links

The first 200,000 plug - in hybrids and electric vehicles receive a zero gram per mile CO2 emissions value in compliance calculations ¹.

manacker: If I understood Mike Rossander's calculation as cited by Mike Jonas above, it shows that your poster linking human CO2 emissions to multidecadal climate in the past record does not hold water statistically.

If I understood Mike Rossander's calculation as cited by Mike Jonas above, it shows that your poster linking human CO2 emissions to multidecadal climate in the past record does not hold water statistically.

The British medical journal The Lancet, known for its tobacco Prohibitionist and anti-Israel views, created a commission on Health and Climate Change to promote, as if it were science, the view that «to avoid the risk of potentially catastrophic climate change impacts requires total anthropogenic carbon dioxide (CO2) emissions to be kept below 2900 billion tonnes by the end of the century» — not a calculation that physicians, biologists, and the like are particularly qualified to make.)

Sorry, but your calculations for CO2 growth are nonsense — you are comparing the rate of growth in population to the growth in the absolute amount of CO2 in the atmosphere, but you should instead be comparing it with the rate of growth of our annual emissions.

When economist Richard Tol did the calculation last year, he found that the private benefits of consumption that created CO2 emissions were something like $ 411 per ton of CO2 emitted, ten times the Obama Administration's social cost of carbon.

Consequently, the most advanced climate models now require, in addition to concentrations or emissions of greenhouse gases (CO2, CH4, N2O and halocarbons), emissions of reactive gases and aerosol precursor compounds (SO2, NOx, VOC, BC, OC and NH3), to model atmospheric chemistry and interactions with the climate system.6 For most variables, a sectoral differentiation would improve the quality of the calculations (e.g. from power plants and agricultural burning).

In a Feb. 3, 1981 letter to Gene Northington at Research and Engineering, Gervasi challenged a «rough calculation» that Northington had made of the CO2 emissions from producing Natuna's gas and burning it as fuel.

Winners were selected from projects submitted for the AIA Portland 2013 Design Awards and, in addition to reduced energy consumption, submissions were required to include a calculation of operational carbon dioxide (CO2) emissions.

The only time you need to know your CO2 emissions before doing the calculation is for the base year.

The main objections levied by Michaels and Dayaratna were that the Obama Administration's calculations assume too much warming from CO2 emissions, underestimate the positive effects of increased CO2, and favor low discount rates to accentuate damages in the far future.

1) On the basis of climate model calculations IPCC states only what kind of assumtions are needed by means of which the recent warming is made seem probably to be caused by antropogenic CO2 emissions, without any proper, empiric evidence.

Data is presented on CO2 band emissions for use in calculations.

Idso's calculations for climate sensitivity are greatly at odds with the paleoclimate data; if sensitivity were as small as he proposes, the Milankovic changes in solar forcing wouldn't be enough to kickstart the climb out of an ice age, but this still presupposes AGW, that CO2 emissions will increase the temperature by some amount.

1896 Arrhenius publishes first calculation of global warming from human emissions of CO2.

The second part of the article deals with CO2 - emissions per m2 per kWh, but these figures are exclusively based on the data of the researchers, not on my calculation above.

The worksheets available below constitute the details each entity's production of oil & NGLs, natural gas, coal, and cement from as early as 1854 to 2010, as well as additional sources of emissions (such as vented CO2, flared CO2, own fuel use, and vented or fugitive methane), non-energy uses of oil, gas, and coal, emission factors for each fuel, calculation of emissions attributed to each Carbon Major producer, and several summary worksheets by fuel and for cumulative emissions by all entities.

One calculation by Robert Brown, director of the Office of Biorenewables Programs at Iowa State University, revealed that if the U.S. adopted a cap and trade program in CO2 emissions like the one already in place in the European Union, farmers in the Midwest could almost double their income by using corn stover — the leaves, stalks and cobs that remain after harvest — to fuel pyrolysis.

Forcing by non-CO2 emissions includes a component driven by the response of the carbon - cycle to temperature changes induced by those emissions (as in the calculations for CO2 itself) based on a reduced carbon uptake of 1 GtC per degree warming (Arora et al. 2013; Collins et al. 2013b).

Perhaps that has been done for HITRAN's calculations of the absorption and emission spectra of different materials in the laboratory, but I think it can not have been done for its calculations of CO2's absorptions and emissions in the atmosphere because (fortunately for all life on the planet) the atmosphere can not be placed in a laboratory.
