Climate change and global warming links – refutation of climate change deniers
Posted by: | CommentsHi Hugh,
You say : “…the ten year cooling trend?…”
I say : What utter piffle ! Just look at this chart (link below). It’s
a very simplified form of the temperature charts, just to make it easy
for people like me to refute people like you :- Read More→

Only about 1/7th of China’s vast area is suitable for agriculture due to desertification occasioned by overgrazing. This has been going on for thousands of years, and was the reason for the Mongol hordes invading Europe (they got as far as the gates of Vienna, and right up to Poland)
Desertification is a huge and tabooed subject in China, and sand dunes are threatening to engulf Peking at some point not too far away.
As desertification continues, and more arable land is destroyed, and China’s demand for food grows, this leads to deforestation being exported to eg the Amazon to grow the soya beans to feed cattle for the Chinese.
This article describes a novel concept using existing technology to very quickly a) control the desertification and sand drifts b) enable the establishment of plant species and associated carbon sequestration in improved soils c) the construction of wind farms or CSP connected to Europe by either a lengthy HVDC transmission system, or the local production of ammonia which can readily be transported to eg Europe / USA and easily used as a vehicle fuel d) the construction of a vast area of seawater greenhouses using sea water pumped thousands of miles to be desalinated by solar energy to allow the production of food and or energy crops. (Contrary to what some ill-informed people claim this does not use a huge amount of energy compared to other national uses)
The concept described is ADRECS – Aerially Delivered Re-Afforestation And Erosion Control System which can be applied in any desert area but in particular to the Gobi and other deserts in China which have extremely serious potential effects on world food.
The ADRECS proposal claims to address this issue and the rough calculations show that using standard freight aeroplanes and heavy lift helicopters, the installation could be achieved in a matter of a decade.

Prof Klaus Illum talks about atmospheric C02 levels and climate change
Posted by: | Comments
From – Klaus Illum3 February 2009
The time scales of the graphs above and below differ by a factor 1,000. The composition of the
atmosphere (H2O, NH3, N2O, CH4, O2, …..) has changed during the last hundreds of millions of
years. During the last hundred thousands of years the CO2 concentration has fluctuated at a
much lower level than previously. Climate change risk assessments should refer to the more
recent periods, not to periods millions of years ago when the atmosphere and life on Earth was
very different.
Fred, (Singer)
if the question concerned a particular issue of minor importance, I would’t interfere in this discussion within a field in which I have no professional qualifications.
However, this is not an issue of minor importance to mankind.
Therefore, as a citizen with some experience in reading and apprehending scientific assessments I have an obligation to take a stand in the climate discussion.
To take the position that the anthropogenic GHG emissions are of minor importance relative to natural phenomena is not merely taking an academic standpoint. It means to take on ones shoulders a heavy burden of responsibility for consequences which we will hardly live to experience ourselves.
In actual practice a central question is whether or not to allow the substitution of coal for declining supplies of oil and gas.
Regarding the CO2 concentration experiment, you say: “Nature has made the experiment for us.” referring to a graph in your paper.
Please see the note attached as my comment to that statement of yours.
I do not accept the notion of the long history of the atmosphere and the concurrent development of life on Earth as an ‘experiment’ made by nature which is comparable to the experiment of increasing the CO2 concentration by 50-100% in a climate system which has been relatively stable for the last 10,000 years or so.
Best regards
Professor Klaus Illum

The radiative forcing potential of different climate geoengineering options
Posted by: | CommentsThis paper looks at various wheezes for interfering with global warming – apparently bio-char might be the a good bet, seeding the oceans with iron filings is likely a waste of time.

“Climate scientists: it’s time for ‘Plan B’ ” – The Independent Survey
Posted by: | CommentsAccording the Independent newspaper – Steve Connor, Science Editor and Chris Green.
Friday, 2 January 2009 “An emergency “Plan B” using the latest technology is needed to save the world from dangerous climate change, according to a poll of leading scientists” carried out by The Independent. This is due to the collective international failure to curb the growing emissions of carbon dioxide (CO2) in the atmosphere.
A significant proportion would now support research into such measures as seeding the oceans with iron filings to promote algae growth, seeding the upper atmosphere with sulphate particles to mimic the cooling effect noticed when large volcanoes such as Krakatoa exploded (still detectable in the early 20th Century), the location in fixed orbit of millions of solar mirrors, and the Salter scheme for spraying sea water in the air using thousands of radio controlled, sailing ships, to create fog which increases the earths albedo and on shore precipitation.
Just over half of the 80 international specialists in climate science who took part in the Independent survey think that the situation is now so dire that we need to start seriously considering these kind of geo engineering or “terra forming” approaches.
Its a shame there was no mention of the Desert Rose concept, and the Seawater Greenhouse concept
Most of the comments were sneeringly dismissive of the problem of global warming regarding it as a fantasy.
