Sentences with phrase «less oxygen in the air»

I could have sworn there was less oxygen in the air up here, but I'd actually only climbed the equivalent of two stories and I knew it was probably no more than three - to four - hundred feet above sea level.

The 2009 State of the Climate report gives these top indicators: humans emitted 30 billion tons of of CO2 into the atmosphere each year from the burning of fossil fuels (oil, coal, and natural gas), less oxygen in the air from the burning of fossil fuels, rising fossil fuel carbon in corals, nights warming faster than days, satellites show less of the earth's heat escaping into space, cooling of the stratosphere or upper atmosphere, warming of the troposphere or lower atmosphere, etc..

Not exact matches

During winter when people crack up the heat in the room, the air becomes dry and stuffy due to less circulation of oxygen and the harsh air leads to different sinus and respiratory problems.

In theory, less oxygen and lower air pressure should make athletic flying tougher.

This allowed the carbon to be stored in the seabed instead of being released into the air, and thus less oxygen was needed to react with carbon.

By measuring the size of the largest raindrop imprints (inset) in ash that solidified soon after an eruption 2.7 billion years ago (pocked slab, main image) and comparing them to the imprints made by drops of various sizes and momentums in lab tests, the team estimates that the density of Earth's oxygen - free atmosphere 2.7 billion years ago most likely ranged between 50 % and 108 % of today's air and was certainly less than twice its modern density — a thickness insufficient to offset the dimness of the sun at the time.

Now, if you have all this very cold, nearly freezing water surrounding these ice caps, sucking up carbon dioxide out of the polar atmosphere, at nearly the highest possible rate, 30 times faster than oxygen, and 70 times faster than nitrogen, doesn't it stand to reason that the air that remains might just have a lot less carbon dioxide in it than the atmosphere across the rest of the planet?

In this case, less air enters the lungs and the blood does not receive the proper amount of oxygen.

This means that although the oxygen percentage in the air stays the same, you will still take in less oxygen with every breath you take because the air is less dense, or «thinner».

EANx does this by replacing some of the nitrogen in the air with oxygen, this means you absorb less nitrogen during a dive, which gives you longer no decompression limits.

Water vapour, as Stephen Wilde pointed out above, is anyway lighter than air, but heated will expand more in volume becoming even less dense and rise faster, as will air itself, nitrogen and oxygen.

The higher you get above sea level, the less oxygen there is in the air, which can affect how multiple things, including gasoline, burn.
