Natural gas (NG) is a potential «bridge fuel» during transition to a decarbonized energy system: It emits
less carbon dioxide during combustion than other fossil fuels and can be used in many industries.
Overturning textbook knowledge, the researchers discovered that the trees «exhale»
less carbon dioxide during the day than previously thought, and that forest photosynthesis doesn't decline over the course of the summer.
Not exact matches
The simulations suggested that the indirect effects of increased CO2 on net primary productivity (how much
carbon dioxide vegetation takes in
during photosynthesis minus how much
carbon dioxide the plants release
during respiration) are large and variable, ranging from
less than 10 per cent to more than 100 per cent of the size of direct effects.
But the aged drink had lost much of its fizz, containing much
less carbon dioxide than modern champagne, likely because it had diffused out through the cork
during its centuries under the sea.
During the fermentation process,
carbon dioxide is formed and tries to escape, making the vegetables
less packed.
During the period, the state became -49 %
less carbon dioxide efficient.
During the past 600 million years, the Earth has experienced great extinctions of major fractions of the planet's species of life whenever the present conditions and slightly
lesser temperatures and
carbon dioxide levels occurred.
Lower temperatures =
less melting = more ice = lower temperatures, on and on and until factors # 1 and # 2 rescue us from turning into a giant snowball (or,
during the most extreme ice age, a spate of volcanic eruptions eventually helped belch out enough
carbon dioxide to warm the atmosphere and reset the thermostat.)
Recalculating this amount into the total anthropogenic
carbon dioxide emission in grams of CO2, one obtains the estimate 1.003 Ã — 1018 g, which constitutes
less than 0.00022 % of the total CO2 amount naturally degassed from the mantle
during geologic history.
