CO2 Emission and Absorbtion by Tropical Trees?

Its interesting, bichemist and botanists may give you a good answer wither regard to it.

plant absorb c02 in the days to act photosynthesis. but release it at night as well.

<plant absorb c02 in the days to act photosynthesis. but release it at night as well>

They release it during the day as well, though it is usually swamped by phototynthesis; for the tree to grow, the time-average rate of phototynthesis exceeds the time-average rate of respiration, which is the cause of CO₂ release from all living things on this planet.

some books say so.

especially in the morning, so director suggests people dont sport in a trees in the morning until 8:30.

soemtimes its interesting. from chemical textbook we konw c02 has more heavier specific gravity than air. it alway decline lower position. how does it go up can distroy that ozone above us?

You're confusing carbon dioxide with ozone depleting chemicals (Freon, chlorinated molecules, radicals, etc). Carbon dioxide may be heavier (more dense) than air, but in a turbulent atmosphere, there is no stratification of nitrogen, oxygen, carbon dioxide, etc. Think of heavy water (deuterium oxide) in water. There is no natural isolation of heavy water from water. The ideal solution to things like Global Warming may be chemical decomposition of CO2 back into carbon and oxygen, using solar energy as the energy source, saving the carbon to make synthetic fuels once we run out of oil and even coal, and replenishing oxygen in the atmosphere. We have fouled the oceans badly, significantly increased CO2 concentration in the oceans, fouled the atmosphere and much of the Earth. The great variety and supply of fish in the ocean is being rapidly depleted by "factory ships" that take EVERYTHING from the oceans of the world, depopulating not only the fish, but destroying their breeding grounds.

That might be very energy intensive to reduce carbon dioxide to carbon. Plus you must keep in mind we are talking about concentration differences of parts per million in the atmosphere that you need to remove.

except some chemophiles

someday we can build a huge building which can collect extra co2 automaticlally at its roof, so that energy can by saved much.

for example, we can use interlayer glass like a sandwich filled with co2 in it to keep warm in the winter.

I find this concept of 'offsetting' horrible. What are we saying, we deforest the earth so we can plant trees on it in order to offset the effects of cutting them down? It's just brain washing for comfort/easing of guilt

Good point...

Also why does everyone always talk to Biologist and Meteorologist about global warming not Geophysicist.

Biologists make conjectures on theories, Meteorologists make assumptions on other's mathematical models, but Geophysicist can actually make mathematical models and knows how to use calculus.

Follow the money on this topic… Who is getting rich off of Carbon Credits??

The solution for global warming is planting billions of trees. Why not planting some 100 fruit trees every weekend?

If carbon dioxide is the cause of global warming, then somebody should be able to perform a laboratory demonstration of the effect, but they won't because they can't, and they can't because it isn't.

Water vapor is a more likely contributor to global warming. Anybody can perform a laboratory demonstration of the effect, but they won't because nobody is interested.

Planting trees by the millions is a good way to counteract global warming because it will work no matter what the cause. Even lowly creatures know that it is cooler under a tree during the sunny day but warmer under a tree during a cloudless night. Examine, through a prism, the spectrum of reflected sunlight from the sheen on a smooth leaf surface. Notice the region just beyond the red reflected light. That region is the infrared where those warming rays are reflected back into space.
