All in all, they have zero net effect - once they die, the carbon re-enters the atmosphere. The problem is all the carbon we brought up from the depths of earth. To counter that, you'd need to bury all the dead plants really deep, to get back at the values of carbon that we had few hundreds years ago. | |

The problem is that the same core reason why we produce so much CO2 / CH4 is the same reason we can't easily replenish forests. There are too many people, using too much space (not just what they live on, but the space for roads, work spaces and farmland to keep a person alive). Then, there's non-GHG pollution (e.g. acid rain) that affects plant growth. Some say, if it warms, trees near the equator may die, but will be replaced by trees near the poles. But, as life hasn't flourished near the poles recently, that soil isn't rich, as trees need. | |

The net effect depends on the kind of cloud, and altitude, basically. It's also important to note that water vapor is less of a concern because of a natural self-equilibrating effect. More water in the atmosphere will rain out back to us, and dryer air will increase the rate of evaporation, moistening the air again. CO2 and CH4 don't have quite the same natural balance point. | |

Humans intake Oxygen and exhale Carbon Dioxide, and plants reverse the process. Sure, many of our machines are producing CO2 as well, which has contributed to the massive accumulation in the atmosphere. However, humans have removed a very significant portion of the planets natural vegetation, resulting in far lower processing of CO2->O2 than in the past. I think that global warming could be counteracted by aggressively replenishing the forests. | |
