If photosynthesis produces C6H12O6
Trees are 50% carbon & 50% water
Trees retain and recycle the moisture through the landscape.
Trees move coastal moisture inland
Trees create local microclimates & rainfall and influence global weather patterns.
Water is essential for every biological function in Nature &
Trees keep that water filtered, clean and recycled
Transpiration
Trees can emit up to 1000 litres of water/day, depending on their environment.
Trees transpire to keep cool (like we sweat).
It is 10 degrees cooler in the shade of a Tree!
A natural air conditioner keeping everything cool.
Humidification is the transpiration of a whole Forest.
This moist body of air activates local rainfall & moves moisture inland.
Humidification also influences global temperatures and weather patterns.
Studies (below) have shown that moist ocean air ( isotope H2O18) has influence on rainfall within 400km of the coast.
Trees keep that moist air moving beyond, inland, by recycling the water.
The isotope of the moist transpired air from the Trees is H2O16
Inland rain (H2O16) is dependent on the recycling of the water through the Trees.

“Forests are complex self-sustaining rainmaking systems, and the major driver of atmospheric circulation on Earth,” Makarieva says. "They recycle vast amounts of moisture into the air and, in the process, also whip up winds that pump that water around the world." Science Magazine
Victor Gorshkov and Anastassia Makarieva (Petersburg Nuclear Physics Institute (PNPI)) studied the effects of the Forests and Trees on the movement of water vapour inland.
The biotic pump is a mechanism in which natural Forests create and control ocean-to-land winds, bringing moisture to all terrestrial life. Winds tend to blow from areas of high air pressure to low. But how is a low pressure system created over land? Air pressure depends on the number of gas molecules. When water vapor condenses, it disappears from the gas phase; the number of gas molecules diminishes, and the air pressure falls. Therefore, if we manage to maintain the process of condensation over land, the latter becomes a persistent low pressure zone.
Water vapor in Earth’s atmosphere possesses a remarkable physical property: it is unstable to condensation. This means if an air volume containing a lot of vapor is occasionally displaced upward, the air will cool so significantly that the vapor condenses. Due to this instability, if there is a sufficient amount of water vapor in the warm lower atmosphere condensation will occur.
The green foliage and branches of Trees have a much greater cumulative area than that of a Tree projection on the ground. Hence, Forest evaporation enriches the atmosphere with water vapor more efficiently than evaporation from an open water surface of the same area. Consequently, condensation occurs more readily over Forests than over the ocean. Forests, rather than the ocean, become the low pressure zone where the moist winds converge to. Completing the cycle, moisture precipitates over the land and returns to the ocean in the form of river runoff.

Prof Clive McAlpine from University of Queensland explains that not only does land clearing release greenhouse gases into the atmosphere, it also has an effect on climate, well beyond the emissions.
“It causes warming locally, regionally and even globally, and it changes rainfall by altering the circulation of heat and moisture,” he says.
“Trees evaporate more water than any other vegetation type – up to 10 times more than crops and pastures. This is because Trees have root systems that can access moisture deep within the soil.”
The increased evaporation and rough surface of Trees create moist, turbulent layers in the lower atmosphere, he says. “This reduces temperatures and contributes to cloud formation and increased rainfall. The increased rainfall then provides more moisture to soils and vegetation.

Clem Dodd, a Dharriwaa elder at Walgett, has seen the change.
“It’s getting drier, it’s there for everyone to see,” he says. “You knock all the Trees out, you got no moisture in the ground. And you get no moisture in the ground, you get no clouds, and you get no rain. All you get is dust.”
