"What the IPCC Report Didn't and Couldn't Say
Scientists involved in writing the report said recently that it is already out of date and that its predictions are too conservative. Here are some very important scientific findings (not modeling) from this past year that were not allowed into the report because of a deadline of a year and a half ago for the input of scientific data. This wasn't a dastardly conspiracy, just a rather stupid rule that proved to be quite tragic in light of the alarming scientific data of this past year. Moreover, the political contingent showed up as each report was written by the scientific community, and the political hacks softened up the language every where they could, so the report is not even close to what it should be.
The sea level rise forecast is the most notably skewed. Dr. James Hansen says a more accurate forecast for 2100 is more than 5 meters without measures to reduce CO2 substantially.(1) He, and many others, have said that the report was written without the very recent knowledge of glacial acceleration feedbacks that have surprised the scientists with the rapidity of the melting and flow, making the report's forecasts much too low.
Consequently, the level of urgency that is understood by policy makers around the world will be out of touch with reality and the chance to slow the warming of the planet disastrously diminished.

Recent Temperature Records -
21) 2005 was the Warmest year on Record.
22) 2006 was the 5th Warmest on Record.
23) 2006 was the 2nd Warmest Year on Record for the U.S.
24) '06 Dec. the Warmest December on Record
25) January '07......................Warmest on Record
26) April '07...........................Third Warmest on Record.
27) January-May period.............................tied with 1998 as the Warmest on Record
11 of the past 12 years are the warmest on record, and '07 is clearly on track to make it 12 in a row.
Skeptics say that this is normal 'variability' of the climate. But the more you read of the data of late, you see that it is only varying in the wrong direction.......... everywhere they look.

Remember the earth has a 35 year thermal lag, these are just the cumulative effects up to the and including the 70's! Please refer to number 11 and 12 above. Just since 2000 the rate of increase in emissions has tripled.
Time to drought proof your home and garden, invest in off grid renewable energy systems instead of entertainment, pay off your mortgage, learn a skill that is truly productive, rip up your lawn and plant food instead, keep chickens, and start forming close ties with likeminded neighbors. Learn to live sustainably now, don't put it off. Teach your children.

This is a 2-minute abbreviated version of a mountaintop removal video featured on ilovemountains.org. The video features Woody Harrelson and shows how the mountains and culture of Appalachia are being destroyed by a new form of coal mining called mountaintop removal
There should not be another coal fired power plant built on this planet. Please see the Architecture 2030 discussion on this topic. They propose cutting consumption via our choices relating to the built environment which is absolutely necessary but we must also look at our personal consumption within our buildings as well. How many TV's do we need, how many computers, clothes dryers, ipods, dishwashers, hair dryers, cell phones, stereos, and security systems to protect all this junk. By continuing to demand more electricity to power our unsustainable lifestyles we are tacitly approving mountaintop removal and the construction of more coal fired power plants. Cut your demand now or leave a world of hurt to the children.

“.......the United Nations Food and Agriculture Organisation cite Belgium, France and the UK as ‘extreme examples’ where only 10 percent of retail units account for more than 80 per cent of food distribution. (Food and Agriculture Organisation, 2002) Supermarkets’ reliance on economies of scale and repeatable quality standards inevitably favours larger suppliers and the use of chemicals in preference to environmentally benign agricultural methods. In contrast urban farms and community gardens, tends to be characterised by the use of organic methods and the local sale of produce.”
Urban Agriculture (UA) allows the use of organic waste for composting reducing landfill usage as well as partially remedying the breakdown of nutrient flows which are destroying our oceans and inland waterways, nutrients in the form of oil are pumped from the ground, shipped to refineries, processed into fertilisers, shipped to the farm, sprayed on the earth, washed into the water sources and thence into the sea or transported as food to the consumer and eventually landfilled or flushed down the sewer as waste. We are eating oil. UA offers an alternative to the high food/nutrient miles paradigm of the supermarket distribution model.
This reliance on supermarkets to the detriment of local food production leaves the urban dweller, particularly the poor, vulnerable to supply issues such as price hikes due to rising costs of energy and water as well as crop failure due to drought and future energy shortages, a virtual certainty with global warming and peak oil. Additionally the poor increasingly find themselves in ‘retail deserts’ as the large supermarkets fail to adequately serve more and more poor neighborhoods after having driven the local food supply network out of business or out of town. This leaves fast food as the primary option for many of the developed worlds most vulnerable with all it’s attendant health implications. Fast food as well as other highly processed foods have impacts beyond health.
Studies done in the 70’s, sparked by the oil shortages of that era, indicate that, for example the embodied energy in a typical loaf of white bread is primarily attributable to fertilisers and transport.(Chapman 1975) Here’s how it looked at that time with a total of 5.6kWh/loaf;
8.6% shop heat and light
9.4% non wheat ingredients
23.6% baking fuel
7.4% milling fuel
7.3% tractor fuel
Fertilisers and transport made up 37.6% of the energy embodied in a loaf of bread. While industrial processes have become more efficient since then, packaging and transport have increased. A study done in Britain in 2000 found that the embodied energy in the food consumed by a typical family of four household was 265kWh/m2 (Vale 2000) while the energy used by a typical house at that time was 257kWh/m2. If the energy used by the family car is included the equivalent carbon dioxide emissions of the food used by the household is roughly equivalent to the equivalent carbon dioxide emissions used in the house and for personal transport. (Kramer K.J. et al., 1999) Agriculture has a large equivalent carbon dioxide emission impact because petro chemical fertilisers release nitrous oxides which are 300 times more potent as greenhouse gases than CO2.
It has been suggested that if the UK switched entirely to food produced organically, locally and consumed in season, greenhouse gas reductions in excess of 40 million tonnes/year would result, a 22% reduction in total UK CO2 emissions. (Stanley 2002)
Until about 1920 the food produced in the US released an equal amount of energy upon consumption as the energy used to supply and produce it. By 1970 the energy used to produce food in the US had multiplied on average by a factor of 8. (Steinhart & Steinhart 1971) The energy ratio in the UK by 1968 was .2, the amount of energy derived from edibles divided by the energy used to produce it, thus for every joule of energy released by the food 5 joules were used to produce it. (Leach 1976) Neither figure takes into account packaging, transport, refrigeration, processing, and marketing.
It is also important to eat food in season. Not only have we adapted as primates to eat food in season and thus it is a more natural and healthy practice but eating only produce in season has a large impact on energy usage and thus greenhouse gas emissions. A vegetable requiring a heated greenhouse requires 57 times more energy at 37.15 MJ/kg to produce than a vegetable locally grown in an open field at 1.55MJ/kg. Even shipping produce 2000 km from a country where it is in season is preferable as it uses only 5.8MJ/kg. (Kol, Bieiot and Wilting, 1993) The easiest way to do this is to eat locally grown seasonal produce.
Locally grown can mean many things. In the context of urban agriculture or peri urban agriculture, on the periphery of town, it can mean within walking distance or short delivery haulage. At a local farmers market stall the produce may have been grown in a field on the outskirts of town and been driven in but the customers to the stall are more likely to have walked or cycled to the stall than to have driven a car. Supermarkets on the other hand, being typically situated on busy roads, are much more likely to rely on customers arriving by car in addition to international delivery of the produce itself. Additionally, the produce at the farmers stall will have less packaging and gone through less processing.
As communities practice more and more UA the amount of food miles, packaging and processing reduces even further as the food is traded house to house and neighborhood to neighborhood. Have you planted your veggies yet?

First lets look under the seat at toilet paper. The following quote is from the Sustainable Concepts Newsletter http://www.designforward.net
“Toilet paper, that ubiquitous and apparently indispensable component of modern life, is often manufactured by cutting down the world's forests. In Canada, clear-cut logging claims half a million acres of Ontario and Alberta's boreal forests each year with much of the destruction earmarked for virgin paper tissue products. Similar activity is taking place in the Southeastern U.S. Recently, Greenpeace and the Natural Resources Defense Council have started campaigns to educate the public on the environmental impacts of using these kinds of products.
The good news is that all of this industrial pressure for tissue products can be avoided simply by using recycled paper toilet tissue. In fact, if every household in the U.S. replaced just 1 roll of virgin toilet paper with just 1 recycled roll 424,000 trees would be saved!”

So what is the link to carbon sequestration? While all the business as usual folks go on about clean coal and developing carbon sequestration technology we are literally flushing away the most effective carbon sequestration technology there is, trees.
So please use toilet paper made from recycled content or even better don’t buy it at all, use recycled newspaper or old books and either put it in the bin, burn it in your woodstove, or throw it in your composting toilet. I can’t think of anything better to do with all those old Michael Crichton novels.
