Called AmazonFACE (Free - Air Carbon dioxide Enrichment), it's based on a simple idea: For 12 years, researchers will spray pure CO2 into instrumented plots in the rainforest northwest of Manaus, Brazil, raising ambient concentrations to 600 parts per million — a level the world could reach as early as 2050 — all the while taking meticulous measurements to determine how the gas affects the growth of plants.

Climate change, resulting in more frost - free days and warmer seasonal air temperatures, can contribute to shifts in flowering time and pollen initiation from allergenic plant species, and increased CO2 by itself can elevate production of plant - based allergens.137, 15,16,17,18,19,138 Higher pollen concentrations and longer pollen seasons can increase allergic sensitizations and asthma episodes, 20,21,155,22 and diminish productive work and school days.138, 22,23

I think what Alastair is alluding to is the fact that, say by 2050 when the arctic ocean will conceivably be ice - free in the summer, the atmosphere will have a much higher relative humidity than it has currently because of the open air = water interface, so this will have a magnifying effect beyond just the feedback from increased CO2.

Free - air concentration enrichment (FACE) technology has now facilitated large - scale trials of the major grain crops at elevated [CO2] under fully open - air field conditions.

If we can not agree on that step, then we can not have markets as the main force in solving problems, since markets do not define the problems to be solved without costs being assigned to «free» things like air, water and CO2 emissions.

If the development of this air - to - fuel process plays out on a commercial scale, it could be used to both capture excess CO2 from the environment (or used at carbon capture points), as well as produce «guilt - free» gasoline.

Climate change, resulting in more frost - free days and warmer seasonal air temperatures, can contribute to shifts in flowering time and pollen initiation from allergenic plant species, and increased CO2 by itself can elevate production of plant - based allergens.137, 15,16,17,18,19,138 Higher pollen concentrations and longer pollen seasons can increase allergic sensitizations and asthma episodes, 20,21,155,22 and diminish productive work and school days.138, 22,23

Scientists make CO2 measurements in remote locations to obtain air that is representative of a large volume of Earth's atmosphere and relatively free from local influences that could skew readings.

So if I understand the basic flow chart, the plant will suck in 80 kilotons of air per second, cool it enough to cause the CO2 to precipitate out, and pump the 80 kilotons (minus 32 tons of CO2) of CO2 free air far enough away to prevent it from mixing with the intake.

, so that the CO2 free exhaust won't dilute the CO2 in the intake air and reduce the processing efficiency.
