RE: Sea levels aren't dropping, Polar bears aren't increasing and other weak anti-climate arguments - debunked.

Global warming is such a very important issue to discuss. I hope they put more effort to it because mother Earth seems hungry for green leaves and trees.

    Hm, yet the more effort put in, the more resistance it gets from the politically motivated (as you can see in a comment below)

      Rising CO2 levels has actually been good for green leaves and trees.

      Global warming alarmists and hoaxers, of course, have warned that CO2 levels crossing the threshold of 400ppm will spell certain doom for the human race. What they don't mention is that rising CO2 levels actually set off a "global greening," complete with forests re-growing at an accelerated rate, gardens producing more food and arid regions seeing a restoration of green plants.

      Impact of CO2 fertilization on maximum foliage cover across the globe's warm, arid environments

      Abstract
      [1] Satellite observations reveal a greening of the globe over recent decades. The role in this greening of the “CO2 fertilization” effect—the enhancement of photosynthesis due to rising CO2 levels—is yet to be established. The direct CO2 effect on vegetation should be most clearly expressed in warm, arid environments where water is the dominant limit to vegetation growth. Using gas exchange theory, we predict that the 14% increase in atmospheric CO2 (1982–2010) led to a 5 to 10% increase in green foliage cover in warm, arid environments. Satellite observations, analyzed to remove the effect of variations in precipitation, show that cover across these environments has increased by 11%. Our results confirm that the anticipated CO2 fertilization effect is occurring alongside ongoing anthropogenic perturbations to the carbon cycle and that the fertilization effect is now a significant land surface process.

      @mobbs is anti-carbon dioxide

      • anti-carbon-dioxide = anti-plants
        • Plants are food.
        • Plants produce oxygen.
