Sentences with phrase «trapping carbon dioxide in the air»

Volcanic eruptions may have put enough heat - trapping carbon dioxide in the air to warm methane frozen in the seafloor and allow it to belch to the surface, a team led by Micha Ruhl of Utrecht University in the Netherlands writes in the July 22 Science.

Not exact matches

A possible cause of SIDS is thought to be an infant's «re-breathing» exhaled air (carbon dioxide) that becomes trapped in pillows or soft bedding close to their face, or around their nose and mouth.

Rebreathing exhaled carbon dioxide trapped near an infant's airway by bedding has been suggested as a possible mechanism for the occurrence of SIDS in at - risk infants and may occur with the use of soft bedding, covering the head during sleep, and use of the prone sleep position.9 - 12 Inadequate ventilation might facilitate pooling of carbon dioxide around a sleeping infant's mouth and nose and might increase the likelihood of rebreathing.13, 14 Increased movement of air in the room of a sleeping infant may potentially decrease the accumulation of carbon dioxide around the infant's nose and mouth and reduce the risk of rebreathing.10 A recent study15 showing a significantly reduced risk of SIDS associated with pacifier use further supports the importance of rebreathing as a risk factor for SIDS.

In addition to the isotope concentration, the air bubbles trapped in the ice cores allow for measurement of the atmospheric concentrations of trace gases, including greenhouse gases carbon dioxide, methane, and nitrous oxidIn addition to the isotope concentration, the air bubbles trapped in the ice cores allow for measurement of the atmospheric concentrations of trace gases, including greenhouse gases carbon dioxide, methane, and nitrous oxidin the ice cores allow for measurement of the atmospheric concentrations of trace gases, including greenhouse gases carbon dioxide, methane, and nitrous oxide.

Growth rates for concentrations of carbon dioxide have been faster in the past 10 years than over any 10 - year period since continuous atmospheric monitoring began in the 1950s, with concentrations now roughly 35 percent above preindustrial levels (which can be determined from air bubbles trapped in ice cores).

Although there is much less of it in the air, it is 33 times more effective than carbon dioxide at trapping heat in the atmosphere and adding to greenhouse warming.

Locked in bubbles of ancient air trapped in glaciers is a precise record of carbon dioxide stretching back 160,000 years.

So far, the political pressure to produce domestic oil in a hurry has trumped public concern about the environmental cost of flaring, which includes local air pollution but mainly comes through the heat - trapping influence of the carbon dioxide produced when the gas is burned.

Healthy forests protect watersheds and generate clean drinking water; they remove carbon dioxide (a greenhouse gas that traps heat in the atmosphere) from the air and thus help maintain the climate.

What's so frightening to them is that after one of the regular warming periods begins, they can see (in air bubbles trapped in glaciers from those past times) that CO2 starts increasing, and they know that this is because of the warming and thawing of vast natural stores of carbon dioxide in the oceans — as well as in the frozen or frigid earth of the northern tundra.

This strategy could help policy makers overcome a fundamental conflict in the debate over global warming: carbon dioxide, the main heat - trapping gas in the air, is an unavoidable byproduct of burning fossil fuels like coal and oil — and combustion of fossil fuels is the foundation of industrial societies.

Is the carbon dioxide in the carbon dioxide filled bottle «trapping more heat» than the air in the air filled bottles, as is claimed by school teachers all around the country?

By far the best match was to the record of atmospheric carbon dioxide, measured from atmospheric samples and air trapped in polar ice.

Wenk Physics Institute, University of Bern, CH — 3012 Bern, Sidlerstrasse 5, Switzerland Studies on air trapped in old polar ice1, 2 have shown that during the last ice age, the atmospheric carbon dioxide concentration was probably significantly lower than during the Holocene — about 200 p.p.m. rather than 270 p.p.m.. Also, Stauffer et al. 3 recently showed by detailed analyses of Greenland ice cores, that during the ice age, between about 30,000 and 40,000 yr BP, the atmospheric CO2 level probably varied between 200 and 260 p.p.m..

This heat - trapping, warming influence of the blanket of air over the Earth's surface is called the greenhouse effect, and it will become even stronger as greenhouse gases such as carbon dioxide, methane and water vapor increase in concentration.

The pattern is linked to the rising and falling levels of carbon dioxide in the air, which traps heat.

When emitted into the air at the quantities humans produce — over 35 billion tons annually (over 3x our trash production)-- carbon dioxide traps heat that would otherwise escape from the planet's surface, in turn causing climate change.

The gradual but systematic rise of 1.5 degrees C is best explained by the record of atmospheric carbon dioxide, measured from atmospheric samples and air trapped in polar ice.

Glacial ice and air bubbles trapped in it (top) preserve an 800,000 - year record of temperature & carbon dioxide.

Air bubbles trapped in the ice and chemical clues about atmospheric carbon levels in corals have shown that there is now more carbon dioxide in the air than at any other point in the history of human civilizatiAir bubbles trapped in the ice and chemical clues about atmospheric carbon levels in corals have shown that there is now more carbon dioxide in the air than at any other point in the history of human civilizatiair than at any other point in the history of human civilization.

And the industrial countries became wealthy largely by burning the coal and oil that produced most of the heat - trapping carbon dioxide that is now in the air.
