less carbon dioxide than fixed - wing aircraft, but he declined to predict
when the companies would be able to announce a launch customer.
Natural gas, which is mainly methane, may generate
less carbon dioxide than oil and coal
when burned, but as recent research has found, there's more to greenhouse gas emissions than just combustion.

less gas
when they drive, and so release fewer
carbon dioxide (CO2) emissions.
Today we are pushing the
carbon dioxide level to a height it last reached 24 million years ago,
when there was a lot
less ice on Earth and the climate was very different.
«
When taking into account that production of the far smaller batteries of plug - in hybrids is associated with
less carbon dioxide emissions than production of the larger batteries of electric vehicles, their
carbon dioxide balance is even better,» says Patrick Jochem of KIT's Institute for Industrial Production.
It produces no
carbon dioxide exhaust emissions, and even
when the CO2 released in generating the electricity used to charge its batteries is factored in, it is responsible for
less than half the amount emitted by the «greenest» petrol cars.
Natural gas produces
less than half the
carbon dioxide of coal
when burned.
When you account for these factors, corn ethanol — currently the most widely produced biofuel in the United States — generates about 43 percent
less carbon dioxide than gasoline.
Another factor, the carbonic acid's stability, makes it
less acidic — carbonic acid reverts to
carbon dioxide and water
when the pressure is released (
when you open the bottle), and this causes the bubbling that can be seen.
When run in Europe's standardized fuel economy and emissions test cycle, the Flextreme is expected to produce
less than 60 grams of
carbon dioxide per mile.
With human
carbon dioxide production accounting for
less than 3 % of the earth's total natural
carbon dioxide production it is ludicrous to think any small reduction we might make would be perceptible — Remember going back to the old stone age before mankind had fire (
when the climate was warmer than it is now) would result in a
less than 3 % reduction in
carbon dioxide production.
Was human life expectancy significantly
less when carbon dioxide was lower?
They further question the claims that a pre-industrial or «below 350 ppm [
carbon dioxide]» climate is necessarily more benign or
less affected by extreme weather, and they warn that «unachievable» CO2 emissions reduction policies are at risk of being classified as «ill advised, ineffective, and disingenuous» if and / or
when the public eventually recognizes how flimsy the evidence is upon which these policies are based.
And as to his claim that there may be «places around the world where global warming will lead to
less crop success and yield, even
when taking into account the
carbon dioxide fertilization effect,» he appears to be equally ignorant that rising levels of atmospheric CO2 tend to raise the temperature of optimum plant photosynthesis beyond the predicted temperature values associated with global warming, effectively nullifying this worn out claim (Idso & Idso, 2011).
Because the day's heat takes longer on average to pass through all those layers than it did
when there was
less carbon dioxide, Earth's average temperature has gone up.
Moreover, even
when emissions from the generation of electricity (upstream emissions) were considered, electric vehicles produced 21 times
less carbon dioxide equivalent emissions per year than their gasoline - powered alternatives.
Scientists complained that the programme makers distorted evidence, and made elementary mistakes such as claiming that volcanoes produce more
carbon dioxide than human activities,
when in fact they produce
less than 2 % of that caused by the burning of fossil fuels.
The study also contains a cautionary note: if effective heat capacity should prove to be
less than estimated in the study, or the
carbon dioxide degassing timescale proved longer, it could result in temperature overshoots in which initial temperature decreases are reversed
when carbon dioxide re-accumulates in the atmosphere.
And in fact
when you look at the scientific literature, it's an interesting disconnect because the modelers who study emissions and how to control those emissions are generally much more comfortable setting goals in terms of
carbon dioxide and other greenhouse gas concentrations because that comes more or
less directly out of their models and is much more proximate or more closely connected to what humans actually do to screw up the climate in the first place, which is emit these greenhouse gases.
So
when you add all the «forcings» together, the atmosphere today «sees» a warming equivalent to about 360 ppm of
carbon dioxide, slightly
less than today's concentration.
Even Obama administration officials have said gas was a «bridge fuel» to a green energy economy because it emits
less carbon dioxide than coal
when burned for power.
And you also knew, for example, that that an average gas driven car emitted 4.7 tons of
carbon dioxide per year and an electric car would cut that in half even
when powered from the current polluting grid, and much much
less on a life cycle basis from a future global efficient renewable energy system displacing almost all fossil fuels.
[10] Although new power plants,
when equipped with state - of - the - art pollution controls, have significantly
less of the type of pollutants that cause acid rain, fine particulate pollution, and mercury toxicity, no currently proposed plants include any equipment to capture emissions of
carbon dioxide.
Methane has the advantage over oil and coal of producing
less carbon dioxide gas
when burned.
Roberts responded: «Um... for example,
carbon dioxide... ah... has been, whenever we talk about
carbon dioxide on the ABC... um... you see on the news broadcast billowing steam pouring out, giving people the impression that
carbon dioxide is both... um... colourful and it's also huge in volume
when it's
less than 0.04 per cent.»
When the air's
carbon dioxide levels rise --- to 400, 600 or 800 ppm — the stomata shrink in size, causing them to lose
