Day-night-temperature average over earth atmospheric layers : Taverage= (TMin+TMax)/2

• Exosphere : +1200°C
• Thermosphere : -86,5°C=>1200°C
• Mesosphere : -2,5°C=>-86,5°C
• Stratosphere : -56,5°C=>-2,5°C
• Troposphere : 15°C=>-56,5°C

Over the past 4 millennia, near earth surface, tropospheric temperature went up to about 60°F and down to 54,3°F with 57°F or 15°C average

Although CO2 is a heavy gas, somehow CO2 succeeds to escape from the troposphere and get higher up into the stratosphere ...

• Earth rotational centrifugal force swings tropospheric CO2 out into the stratosphere ?

Natural atmospheric pressure is too weak to compress CO2 from gas to liquid nor solid at room temperature ...

Only in winter low temperature on the poles you can get CO2 from gas to liquid or solid ...

Where did the 7000ppmV CO2 go to over the past half a billion years ?

• We are missing about 7000ppmV-425ppmV=6575ppmV CO2 ?

Earth rotational centrifugal force did swing 6575ppmV CO2 out into space ?

Now 6575ppmV CO2 is coming back from space or from somewhere else, according to the Dr. Ralph Keeling CO2-curve at an annual rate of +2ppmV per year ?

• Per day about 100 MegaTon CO2 from carbon energy production for almost 8 billion humans on earth ?

• Average : 12,5kg CO2 per human per day

Private jet flyers may make a high peak to average ration in the statistical distribution on this 12,5kg CO2 per human per day ...

• Dry ice, or?solid?carbon dioxide, is the?solid state?of CO2?gas below -109.3?°F (-78.5°C).
• Dry ice does not occur naturally on earth but is man made.
• It is?colorless.
• People use dry ice to make things cold, and to make drinks fizzy, kill?gophers, and freeze?warts.
• The?vapor?of dry ice causes?suffocation?and eventually, death.
• Caution and professional assistance is recommended whenever dry ice is in use.

• Carbon dioxide?(CO2) is a?chemical compound?and is acidic. It is a?gas?at?room temperature. It is made of one?carbon?and two?oxygen?atoms. People and most animals release carbon dioxide when they breathe out. Also, every time something organic is burnt (or a?fire?is made), it makes carbon dioxide.?Plants?use carbon dioxide to make?food. This process is called?photosynthesis.[1]?The properties of carbon dioxide were studied by the?Scottishscientist?Joseph Black?in the 1750s.

Carbon dioxide is a?greenhouse gas.[2]?Greenhouse gases trap?heat energy. Greenhouse gases change the?climate?and?weather?on our?planet,?Earth. This is called?climate change. Greenhouse gases are a cause of?global warming, the rise of Earth surface?temperature.

Its concentration in Earth's atmosphere since late in the?Precambrian?was regulated by?photosynthetic?organisms and geological phenomena (mainly volcanos).

Biological role[change?|?change source]

Carbon dioxide is an end product in organisms that obtain energy from breaking down sugars, fats and?amino acids?with?oxygen?as part of their?metabolism. This is a process known as?cellular respiration. This includes most?animals, many?fungi?and some?bacteria. In higher animals, the carbon dioxide travels in the blood from the body's?tissues?to the?lungs?where it is breathed out. Plants take in carbon dioxide from the?atmosphere?to use in?photosynthesis.

Dry ice[change?|?change source]

Dry ice, or?solid?carbon dioxide, is the?solid state?of CO2?gas below -109.3?°F (-78.5°C). Dry ice does not occur naturally on earth but is man made. It is?colorless. People use dry ice to make things cold, and to make drinks fizzy, kill?gophers, and freeze?warts. The?vapor?of dry ice causes?suffocation?and eventually, death. Caution and professional assistance is recommended whenever dry ice is in use.

Dry ice when put in water

At usual pressure it will not?melt?from a solid to a?liquid?but instead changes directly from a solid to a gas. This is called?sublimation. It will change directly from a solid to a gas at any temperature higher than extremely cold temperatures. Dry ice sublimates at normal air temperature. Dry ice exposed to normal air gives off carbon dioxide gas that has no color. Carbon dioxide can be liquified at pressure above 5.1?atmospheres.

Carbon dioxide gas that comes off of dry ice is so cold that when it mixes with air it cools the water vapour in the air to fog, which looks like a thick white smoke. It is often used in the theater to create the appearance of?fog?or?smoke.
