Sentences with phrase «releases less carbon dioxide»

Not exact matches

Industrialized countries with less than a quarter of the world's population are responsible for about three - quarters of the carbon dioxide released by burning fossil fuels.

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.

The researchers found that in hot years, trees in a Costa Rican rainforest grow less, and the tropics worldwide release lots of carbon dioxide (CO2).

In Maine, cooking the same turkey in the same oven but with electricity generated primarily from renewable energy releases less than three pounds of carbon dioxide.

Owners can burn less gas when they drive, and so release fewer carbon dioxide (CO2) emissions.

At higher temperatures, less of the gas is absorbed, and the ocean releases more carbon dioxide into the air, contributing to a runaway greenhouse effect.

Less than a micrometer in diameter, it's the most abundant photosynthetic organism on Earth, taking up carbon dioxide and releasing oxygen.

It produces less carbon dioxide emissions than coal for electricity or gasoline and diesel for fuel, but even a small amount of natural gas release — which is essentially methane — packs a greenhouse gas punch about 30 times more powerful than the same amount of carbon dioxide.

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.

The new study suggests that the impact may have released around three times as much sulfur and much less carbon dioxide compared with previous estimates from 20 years ago.

Scientists measured how much carbon dioxide the artificially warmed plants respired — released into the air via their leaves — and learned that over time, the trees acclimated to warmer temperatures and increased their carbon emissions less than expected.

For it to remain likely that we stay below two degrees, the total amount of carbon released through carbon dioxide emissions must be less than 1000 billion tonnes, the IPCC says.

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.

• albedo decreases as ice melts (ice is perhaps 80 % reflective, while ocean albedo can be as low as 3.5 %) • increased water vapor in a warmer climate • warmer oceans absorb less carbon dioxide • warmer soils release carbon dioxide and methane • plants in a hotter climate are darker

But because they are released in tiny traces, they currently contribute less than 1 percent of the climate - warming effect from human - generated carbon dioxide.

John Sterman, a professor at the MIT Sloan School of Management, published a paper earlier this year that argued burning pellets would release more carbon dioxide than coal in the short term because it was a less efficient source of energy.

In 2010, the Yale Project on Climate Change released a study claiming that «less than half of Americans (45 percent) understand that carbon dioxide traps heat near the Earth's surface, and a majority think that the hole in the ozone layer contributes to global warming.»

As the temperature increased in the past, oceans also released more carbon dioxide because warm water holds less carbon dioxide than cold water.

And, going back to the Little Ice Age, with the oceans appropriately a lot cooler than today they could hold more carbon dioxide and less was released into the air.
