In fact, we run cattle on our ranch. If people didn't eat beef, I'd lose a source of revenue! g And even quite a pessimistic estimate of CO2 emissions from beef gives 40kg CO2 per kg beef; at a remediation cost of $50/ton that doesn't add that much to the price of beef cuts worth the eating. Some do. Many don't. One problem is that things are set up in a way that hides true costs. For instance, energy generated from coal and oil is quite a bit more expensive than energy generated from wind or solar. But since the true costs of the former are hidden, and not paid by the users in any obvious way, these seem economical. Again, remediation costs just aren't that big; 1kWh from coal is about a kilo of CO2, about five cents to remediate, which is I think a good deal smaller than the differential between the pricing of coal and wind power now. Wind and solar power are likely to get cheaper, and the convenience of not needing fuel is a great one. It's possible that I'm committing the fallacy of scale with my discussions of remediation: if I want an 8" SCT tomorrow, it costs only money, whilst I can't get a million 8" SCTs tomorrow for any sum of money because it takes longer than that to make them and there aren't that many in stock, or an 80" SCT tomorrow for any sum of money because there's only the one in the world, it would take some time to negotiate with the Karl Schwarzchild Observatory to buy it, and some time to move it. If the remediation requires a forest of quick-growing trees larger than Earth's arable land area, it's not going to work. Tom |

Large scale use of wood for energy would cause massive deforestation, increase the CO2 and reduce the amount of greenery that might counteract that CO2. *You just choose not to notice that. http://www.usatoday.com/news/nation/...od-power_N.htm QUOTE: "One of the world's oldest energy sources is making a comeback. Across the USA, power plants are turning to wood to make electricity. The move is spurred by state mandates to encourage renewable power and by bills moving through Congress that require more renewable electricity nationwide. Wood power's rise is "meteoric," says William Perritt, editor of Wood Biomass Market Report. One wood-burning plant started up in 2007, seven in 2008 and a dozen in 2009, he says". There is considerable interest in growing Willow as a source of heat energy with regular harvesting of saplings followed by rapid regrowth and multiplication from the living crown. There is no need to grow large trees for large split logs over several decades. I believe the willow is chopped and used in pelleted form with screw-fed automatic boilers much like commercially available, compressed sawdust pellets. Our own Willow cuttings planted as an ornamental hedge are multi- stemmed and over ten metres high after only a few short years. |

The United Nations (Home of the IPCC) isn't very happy about beef production. Yes, it's a problem on multiple fronts. The solution is similar to that for fossil fuels: tax beef production to reflect its true cost. There's no need to tell people what they can or cannot eat; if beef cost $15 per pound, consumption would drop to sustainable levels. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |

Of course it would.. *The wealthy elite, (like Al Gore and Michael Moore) could continue to fatten up on cheese burgers, and the President could keep serving $100 per lb Kobe beef at his functions while the poor folk grew leaner eating turnips. How many farmers and auxiliary industries (like beef processors) would go out of business if beef were $15 per Lb? * What effect would that have on the economy? *(Not just the US but the world economy). I say again... *The average American (or world citizen) has NO idea what's coming down the pike and what they will ultimately have to sacrifice in order to "stop" global warming. If they did, they might show more interested in the growing evidence that AGW has not only stopped, but is in retreat. How's your Danish? As bad as your science? Then just look at the pictures.

I'll throw in a BBC article if you're interested. http://news.bbc.co.uk/2/hi/8299079.stm . You might read what the UK Met office has to say http://www.metoffice.gov.uk/climatec.../slowdown.html The first paragraph reads … trends over the past 10 years show only a 0.07 °C increase in global average temperature. Although this is only a small increase, it indicates that there has been no global cooling over this period. In fact, over the past decade, most years have remained much closer to the record global average temperature reached in 1998 than to temperatures before the 1970s. All the years from 2000 to 2008 have been in the top 14 warmest years on record. Several key points: 1) The last ten years have shown a 0.07 °C INCREASE NOT COOLING. 2) the eight year period 2000-2008 have been in the top 14 warmest years on record. The BBC reporter who wrote the story (Paul Hudson) cann't even copy word for word what he claims is a UK Met Office report. |

[1]http://www.npower.com/web/fuelswitching/index.htm The reason you are getting these solicitations linking carbon dioxide with global temperature levels is due to the absence of astronomers,nothing more or less. The job of an astronomer is not just to make sense of celestial observations as we look out into the celestial arena and as these observations from a moving Earth apply to solar system structure or something larger but also apply planetary dynamics to terrestrial effects and unfortunately this is not happening.There is even a severe aversion to the normal relationship between daily rotation and orbital motion as it applies to the current seasonal temperature drop seen in place like New England as 'tilt' does not cause the seasons but rather a simple additional orbital specific which can be demonstrated easily and observed dramatically (Uranus) satisfies the difference between seasonal weather patterns and global climate which encompasses it. It is extremely agonizing to see people actually gloat that they can simply ignore the two basic motions which are responsible for not just the daylight/darkness cycle but also variations in daylight/darkness that follow seasonal temperature drops so they can discuss global climate from the point of view of what comes out of a chimney or a tailpipe instead of the magnificent astronomical principles which create global climate in the first place. |
