Richard Lawson. On how not to saw off the branch which you are standing on.
RichardA delay of the climate's response would explain that; but it also would mean that what we see as an reaction to human influnce today has been triggered from our impact during the seventies, sixties, may be the forties...If that was true we will be coming late; much too late!Christian A. Wittke
Yes, we have a problem. Even if we magically cut all CO2 emissions today, we would still be looking at significant warming, as there is a 40-50 year time lag. And then there are the positive feedbacks...That is why I am a bit of a heretic on the carbon sequestration debate: I believe we have to reforest the planet.http://greenerblog.blogspot.com/2006/11/climate-change-email-list-throws-up.htmlThis is my take on reforestation:http://www.greenhealth.org.uk/DesertRose.htmAlso, I back research on ocean fertilisation. We have find where to place the iron precisely, so that by the time the algal bloom is maximised, it is over an ocean sink.The task is enormous. I've just worked out that every year we release carbon that took about 67,000 years to sequestrate.However, Gaia has absorbed about 50% of our emissions already.We have to try, because if we don't try, we are like turkeys waiting for Christmas.I always say Green activism is like a parachute on a hang glider: it may or may not save your life, but at least it gives you something to keep your mind occupied as you plummet downwards.And reserve parachutes do work.I like your blog.http://efficiencymeetssustainability.blogspot.com/CheersRichard
Thanks DocRichard!1I agree, reforestation is needed, fast and furious, simply because wood is not C neutral at all!(http://efficiencymeetssustainability.blogspot.com/2009/02/whats-so-neutral-about-wood-time.htm)How can C be C-neutral, what delusive rubbish.2CCS is a technological gimmick, early days, and even if once reliable will never work in a big enough scale.http://efficiencymeetssustainability.blogspot.com/2009/02/cart-before-horse-i.html3Research on geo engineering is required urgently; however, any application needs to be thoroughly looked at and counter-checked on its sustainability, i.e. any possible un-wanted/un-known side effects. I am afraid it might offer vast open fields for neo-lib lobbies establishing new rounds on new gambling tables.http://efficiencymeetssustainability.blogspot.com/2009/02/can-geo-engineering-rebuild-planet.html4Energy saving technology and procedures are far from being deployed, not even fully explored. This needs to include all and any production cycle.http://efficiencymeetssustainability.blogspot.com/2009/05/picnic.html5In the end it needs a different economic goal setting, a different global society defining “growth” e.g. as something quality related; quality of life, health and death, of education and work, of fun and entertainment. I know it sounds odd and we have heard that too often from too many dubious do-gooders.However, this does not make it the wrong alternative – it is our only one!Good luck, Richard.Christian A. Wittke
Blogs are so informative where we get lots of information on any topic. Nice job keep it up!!_____________________________Students Resource

Might world war in the middle of last century have had something to do with it? Quite a lot of smoke....Found your blog via GreenWorld 67: very timely, as I'm giving a talk on climate change later this month. So many thanks for the material ! More comprehensive even than www.logicalscience.com .steve platerKent
Hi SteveI wondered that too, but if you look at the larger figure, the temp climb starts before the war, and falls away as the war progresses - if, indeed, wars can be said to progress. Smoke and soot does have that effect. It is considered that the industrial pollution of the 1960s had a cooling effect.What I like about this figure is that it shows that climate models do work, although they will be refined in the future.
This kind of information is very limited on internet. Nice to find the post related to my searching criteria. Your updated and informative post will be appreciated by blog loving people. UK Dissertations
And thank YOU for the spam.
