#18: Solar irradiation is already slightly declining, while next Solar cycle is expected to be weaker or much weaker than previously thought. In the meanwhile, since 2003 oceans show a slight but clear cooling trend (I must be precise: we cannot say it is clear because it is below error range; but, since someone is saying that GW accelerated in the last decade, or that the warmest year of the millenium is so for 0.01°C with a 0.1°C error, I think we could call it “clear”). So, I would bet we would have not to wait 15 or 20 years, but right in the next years we should see a slight decline in global temperatures, led both by Solar cycles, and Earth’s cycles (indeed oceans appear to have medium-time temperature cycles): but how much and how fast, I cannot tell you, I studied astronomy but not astrology
But it is curious that, having had a stable decade in global temperatures, someone is telling that in 2010-2012 we should see a new sudden temperature rise like 1998: it is exactly the same period where, basing on just natural cycles (mainly Sun’s ones), we should expect cooling to begin acting sensibly. So, we should wait just 5 years to know who is right and who is wrong: and for then, almost everyone will be still alive.
In the event of cooling in the next decade, outside the worst ever figure for climatology and maybe all science, I would bet on other possible explanations: man-made pollution is leading cooling (e.g. sulphate emissions from China and India); water feedbacks have not been modeled in the right way, but the thoery is good, and anyway Mankind is guilty of every climate change, and anyway now a “cold doom” will soonly arrive; we have just to wait some year (decade, century, millenium) more for the “hot doom” to arrive; it is a global plot, financed by warmongers and oil companies, against environmentalists and IPCC-UN.

88: Really interesting. Certainly the climate scientists are aware of this effect….

Re #88 Everyone should take a look at John’s two maps, and note the differences in visual impression.

I wonder which projection is used by GISS? Let me guess…

I've made available an unmodified surface temperature anomaly map and an area correct version of the same map on the internet. The area distorted original map was much more alarming. Mercator projections are a fraud in this context.

Willis,
Ach, I have done nothing more than create an application that makes a Gall-Peters projection out of a Mercator projection. Are Behrmann and Gall-Peters projections two names for the same thing? They are both equal-area projections. Perhaps “R” knows about them?

gcc along with all the other gnu software is freely available for Windows too. Just go to http://www.gnu.org and look for the Windows binary distributions.

Ah, my Apple-owning friend chimes in:

Me: do Macs come with gcc installed (OS10)?
Him: not by default, but it ships on the OSX DVD (#1) – so, if you want gcc (and all the other tools), stick the DVD in, there’ll be a folder ‘xcode tools’ or something, and you just run the installer

Seeing as Mac OS 10 is based on FreeBSD (with a Mach kernel, IIRC), I'm surprised it doesn't come with gcc. This Apple page makes it sound like it does come with it. Try opening a terminal and typing "gcc --version".

I haven’t tried to run Linux on my mac … does gcc run under Unix?

All you need is a copy of Linux. It comes with gcc.
