Reducing our dependence on fossil fuels is still a good thing for many reasons but global warming/cooling is just one factor. |

Measured global warming has started to level out over the last 20 years and fossil fuel usage has not. None of the existing models account for this leveling off so there is something else going on that is not yet understood. |

It is based on solar activity. According to the report, the level of solar activity goes in 11, 90 and 200 year cycles. The 11 year cycle doesn't affect much but the 200 year cycles have a pronounced affect on global climate. From the report: "Solar activity follows different cycles, including an 11-year cycle, a 90-year cycle and a 200-year cycle" Yuri Nagovitsyn comments. “Evidently, solar activity is on the decrease. The 11-year cycle doesn’t bring about considerable climate change – only 1-2%. The impact of the 200-year cycle is greater – up to 50%. In this respect, we could be in for a cooling period that lasts 200-250 years. The period of low solar activity could start in 2030-2040 but it won’t be as pervasive as in the late 17th century”. http://wattsupwiththat.files.wordpress.com/2013/04/archibald_1749_2049_projected_solar_cycle.png?w=64 0&h=354 |

Reducing our dependence on fossil fuels is still a good thing for many reasons but global warming/cooling is just one factor. If fossil fuels are going to cause global warming and doom mankind, we better just kiss our ass goodby. Europe and the US might cut usage but Asia, Africa and the sub-continent certainly are not doing it. That is where the future energy usage growth is coming from. South America is even more troubling. They are draining the wetlands and burning the rain forests in Brazil to grow sugar cane fuels. All you have to do is drive through Clewiston to see the damage sugar causes. The one that really gets to me is the argument from the left about Keystone. They act like, if we don't build the pipeline, Canada will just abandon that cash cow. Oh, I agree with your position that there are other things to worry about, but that doesn't take away from the fact that global warming is occurring and that the graphs directly correlate with the use of fossil fuels. Except if you listen to FOX. There two critical issues facing the world and they are access to potable water and to oil. |

And there is a third critical issue and that is unchecked/out of control population growth. There is only a finite amount of oil and supplies will eventually dwindle no matter how much is newly discovered. At some point it will become expensive enough that burning it for energy will be unthinkable. It will have much more value as an industrial/chemical feedstock. On the other hand, if global population growth is not reigned in, no amount of water or energy will be enough. |

Let's see, one of my first papers in college was about population growth, with the Club of Rome being a source of information. This was in the early 70's. That would be about 40 years ago, and I don't see the population growth dwindling by much. -- John |

It has actually gotten much worse in fact since India and China have become industrialized since they are now consuming and polluting much more per capita than previously. The catholic church's position on birth control is only part of the problem - more of an issue in the western hemisphere. Even here however the cultural issues outweigh the religious ones. |

And the Catholic Church, with its policy on birth control, isn't helping the situation much. Although, I'd have to admit it probably has little influence in China, India, Pakistan, etc, it most assuredly has influence in Mexico and lands south. I believe Mexicans (or Hispanics) are the fastest growing -- John |
