That’s obviously ridiculous. If the amount of plant mass increases with increased CO2 levels, the plants are converting CO2 into plant matter at a greater rate, and regardless of how they breathe, more carbon is captured in the plant itself as plant matter. The plants don’t create CO2 out of nothing. For the plants to increase the atmospheric CO2 level, they would have to decrease in mass themselves which is the opposite to reality (ref. the greening of the planet and case/control studies of plant growth under enhanced CO2 levels)

Plants and trees survive darkness by converting sugar to energy and heat, the warmer the night the LESS they need that energy for warmth. There is an effect where trees will actually protect the grass underneath them in parts of the world where frost is just an early morning event that then goes away. The trees are generating heat, the average plants DO NOT DO IT. They simply die.
Its the energy cycle of the plants. This is why in dense no-breeze conifer copses you can get that “not enough air†effect, they’ve chewed up a higher average of the ambient oxygen overnight and replaced it with a denser gas.

Well, since you replied to tobyglyn’s post, I have to assume you’re one of those horrible “de-nayers†with his head in the sand. Running off on some crazy rant about “more plants means more breathing†or some-such nonsense whilst refusing to address – at all – the unicorn issue!

You are so wrong … 97% of scientists agree that unicorns poop diamonds

Yeah, and then the massive accumulation of heat energy sequestered at the bottoms of the oceans will suddenly rise, raising atmospheric temperatures by 30 degrees and melting the icecaps overnight, resulting in thousands of mass shootings, millions of rapes, worldwide jihad... /s Thanks Ernest.
