Mostley CO2. Freezing.<br /><br />Tell ne how that works if CO2 increases temperature? <br /><br />Think about it. It may contribute a tiny amount. And as we seem to be heading into a GSM, we need all the help we can get. CO2 as temperature dial is about to receive a test. From the real world. Not models. <br /><br />Getting to the point where Captcah images are so grainy it takes m 7 or 8 goes to get it right. Life's too short.

So low carbon, but not at any cost. And the sooner we start properly counting embedded energy - in buildings, vehicles, stuff - the better. The biggest con of the day is not counting whole-life CO2 cost. Early-replacement of a 10 year old widget that emits 200g of CO2 a year with a widget with a life of 5 years that saves 100g of CO2 a year but costs 3kg of CO2 to make and transport is a con. <br /><br />I can quite happily live without fresh out of season veg flown in from Kenya, winter flowers flown in from Peru and volcanic water shipped from the pacific islands. I could bear without grumbling a doubling of the cost of leisure flying. I can forego four meat meals a week without hardship and would cheer a carbon sales tax on non-medical domestic use of air conditioning. <br /><br />I want to choose how to maintain a low carbon footprint though - not to be forced or coerced. And I won't make sacrifices if I see repulsive con tricks such as the Bloomberg Building being foisted on the public - it's NOT the greenest building in London, it's a hideous carbon-guzzling monster that will NEVER in its lifetime repay the embedded hundreds of thousands of tonnes carbon cost of its construction <br />Raedwaldhttps://www.blogger.com/profile/11699610899843349594noreply@blogger.comtag:blogger.com,1999:blog-32841798.post-60020555688021840792019-06-13T12:46:29.919+01:002019-06-13T12:46:29.919+01:00Whether the CO2 global warming theory is true or n...Whether the CO2 global warming theory is true or not doesn't really matter. The simple point is that we need to build at least a dozen new nuclear power stations over the next 30 years. Otherwise, there will be power cuts and a massive import bill for gas.<br /><br />Nuclear power stations today are safe, clean and have a minimal effect on the environment, unlike wind turbines. They are expensive to build, but they last for a long time.<br /><br />Any suggestion that we can power London in January from batteries is pure fantasy.<br /><br />Don Cox Anonymousnoreply@blogger.com
