A sample of recent scientific news from NIPCC * The Glaciers of Greenland were smaller 5000 years ago; * African savanna trees thrive with increases in CO2; * It was hotter in China a thousand years ago, and by a whole degree; * Marine-life-with-shells can’t agree on their favourite CO2 level and * Temperatures make no difference to the 5000 year record of hurricanes.

Quadrant approached me asking for my response. Dr Glikson replied to my reply, and I replied again to him (copied below). No money exchanged hands, but Dr Glikson is, I presume, writing in an employed capacity, while I write pro bono. Why is it that the unpaid self taught commentator needs to point out the evidence he doesn’t seem to be aware of? Why does a PhD need to be reminded of basic scientific principles (like, don’t argue from authority). Such is the vacuum of funding for other theories that a debate that ought to happen inside the university obviously hasn’t occurred. Such is the decrepit, anaemic state of university science that even a doctorate doesn’t guarantee a scientist can reason. Where is the rigor in the training, and the discipline in the analysis? Credibility lies on evidence by Joanne Nova April 29, 2010 Reply to Andrew Glikson Dr Andrew Glikson still misses the point, and backs his arguments with weak evidence and logical errors. Instead of empirical evidence, often [...] April 29th, 2010 | Tags: Acidification, Antarctica, Climate Models, Corals, Evidence, Glaciers, Glikson (Dr Andrew), Hot Spot, Logic & Reason, Missing Hot Spot, Plant growth, Quadrant, Sea Levels, Sherwood (Steven) | Category: AGW socio-political, Logic & Reason | Print This Post | Email This Post | Comments (176)A little under half (typically about 45%) of the dry weight of any plant is carbon, and almost all that “C” came from CO2 in the atmosphere. No wonder plants love more CO2. Trees and bushes can grow out of cracks in rocks because they suck the carbon right out of the air. Likewise hydroponics is only possible because the building blocks come from liquid and aerial fertilizer. CO2 is about the only “pollution” you can pump around plants and watch them grow faster, stronger, taller and indeed more resistant to most of the stresses that normally bother a plant.
