Are we heating the Earth too much - with heat?

As readers will know, I have been thinking about the hullabaloo about CO2 and global warming and I quickly concluded that CO2 is no threat, won't do any significant warming (which would be good anyway), and is in fact 100% good for the planet. But someone said to me, if CO2 is no danger, that doesn't mean that humans are not causing a danger in some other way. Of course I agreed with this, because there are lots of things humans are doing wrongly and thereby causing terrible damage to our world (and the CO2 storm in a teacup is distracting us all from fixing those real problems).

My friend then went on, however, to propose that the danger was still global warming and that the mechanism was, instead of CO2 greenhouse warming, the mere fact that human technology gives off heat. All the power used by all the machines and transport and so on eventually ends up as waste heat. Maybe that is in itself enough to cause us serious warming trouble? So I did some calculations.

According to the laws of thermodynamics, the process of doing useful work must necessarily lose some of the energy from the fuel in the form of waste heat; and that heat, well, heats. In other words, because of the huge extra amount of useful work we do, we create excess heat that would not have been here otherwise, and that heat has to either be dissipated somehow, or else raise the temperature.

The factors that have caused the ice ages, as we saw, are primarily small changes in insolation (heating) by the Sun. The changes can happen because the Sun’s energy output changes or because of cyclic changes in the Earth’s orbit and inclination, etc., changing the amount of heat that actually arrives on the surface. Changes in the Earth’s orbit are believed to be the triggers for the onset of ice ages, and the changes in heating caused by those changes are thought to be quite small compared to the total power output of the Sun. This might lead us to suspect that human-caused changes in the amount of heat at the surface might indeed have a significant effect on the climate.

Answer to 'Fourteen days to seal history's judgment'

So 56 newspapers are putting up a common editorial pushing the climate hoax. Are these editors: (1) too lazy to investigate the facts for themselves, and/or (2) too incompetent to do so and see the dripping evidence of fraud and political and financial manipulation cloying to this issue like thick red mud, and/or (3) one of the hoaxsters, who knows that the truth is that reducing CO2 emissions will cost lives in reduced food production as well as put endangered species in peril as their wild areas are converted to foodmaking by famished human beings? In other words, are they lazy, stupid, or evil? There is one other possibility, which I'll get to at the end, so without further ado, here is the entirety of their nonsense, with a few comments from me to the 56 editors.

'Fourteen days to seal history's judgment on this generation'

Today 56 newspapers in 45 countries take the unprecedented step of speaking with one voice through a common editorial.

Newsflash: Truth is not decided by majority rule, nor by authority.

We do so because humanity faces a profound emergency.

Yes. The proposed Copenhagen treaty establishes an unelected, socialist government in all but name, with the power to tax every transaction in the western democracies. It will reduce the output of carbon dioxide plantfood, thereby starving humans and animals. This treaty must be defeated. From Lord Monckton's speech about the treaty:

"I read that treaty. And what it says is this, that a world government is going to be created. The word “government” actually appears as the first of three purposes of the new entity. The second purpose is the transfer of wealth from the countries of the West to third world countries, in satisfaction of what is called, coyly, “climate debt” – because we’ve been burning CO2 and they haven’t. We’ve been screwing up the climate and they haven’t. And the third purpose of this new entity, this government, is enforcement.

"How many of you think that the word “election” or “democracy” or “vote” or “ballot” occurs anywhere in the 200 pages of that treaty? Quite right, it doesn’t appear once. So, at last, the communists who piled out of the Berlin Wall and into the environmental movement, who took over Greenpeace so that my friends who funded it left within a year, because [the communists] captured it – Now the apotheosis as at hand. They are about to impose a communist world government on the world. You have a president who has very strong sympathies with that point of view. He’s going to sign it. He’ll sign anything."

Unless we combine to take decisive action, climate change will ravage our planet, and with it our prosperity and security. The dangers have been becoming apparent for a generation. Now the facts have started to speak: 11 of the past 14 years have been the warmest on record, the Arctic ice-cap is melting and last year's inflamed oil and food prices provide a foretaste of future havoc. In scientific journals the question is no longer whether humans are to blame, but how little time we have got left to limit the damage. Yet so far the world's response has been feeble and half-hearted.

A generation ago the lamestream media were telling us that there would be an ice age. Actually that was closer to the truth than your current alarmism, but in neither case was the lamestream opinion based on sound science. The Arctic icecap is actually freezing rapidly as we head into the northern winter, but taking the above misleading remark as a reference to the yearly meltback, the Arctic icecap is almost all the way back to the mean, having increased dramatically for each of the past two years [and notice, readers, how the Antarctic, doing well, is neatly forgotten]. So in what sense is it "melting"? It isn't melting right now, it is freezing. It isn't melting compared to last year, it is growing: 2008 was 10.6% more than 2007, and 2009 was 23.4% more than 2007. Editors, your statement is a lie pure and simple. Nextly, inflamed food prices can be directly traced to conversion of food crops to biofuel. What do you fools editors think will happen when you take a great chunk of the world's food off the food market? And we now know, thanks to climategate, that the insiders have been 'fixing' the peer-reviewed literature, thus making the record found in 'scientific' journals worthless from the point of view of a lay person simply looking for something to trust. It cannot be trusted, period!

Warm or cold? Who's crazy now?

One of the strangest things about the success of the 'climate change' hoax is they way the perpetrators have so successfully got so many afraid of warmth. Whilst successful Americans have for generations fled their New Yorks and their Seattles for the Florida beaches, and Australian Melbournians and Sydneysiders have made the Queensland Gold Coast one of the fastest growing regions in the country, those same people have obediently lined up to condemn and to fear almost unmeasurably small warming trends in world climate. They would rather have their power bills and their food bills doubled, and to deny the benefits of extra food for the poor and for wildlife from enhanced atmospheric carbon nutrient.

Is it really that easy to stampede human beings into cutting their own throats?

Apparently so. The city-based environmentalists imagine, I suppose quite genuinely, that they are the knights in shining armour riding to save the planet.  I put this down to a complete lack of actual familiarity with the real processes of life that keep plants and animals alive - and of which we humans are not exempt. But here are a few things I noticed this week that should make sense even to people trapped in ignorance of the cycle of life.

Review: The Climate Caper - Garth W. Paltridge

This is a reasonably short work, very different from Ian Plimer's Heaven and Earth. Although Paltridge is an atmospheric physicist and erstwhile Chief Research Scientist with Australia's CSIRO, he has put together an accessible summary of some of the damning evidence against the global warming alarmism.

Global Warming: The Precautionary Principle Backfires

I'll probably be posting quite a bit about global warming, and you might wonder why I think it's a big issue for a site devoted to peace. Well, peace is easier if we aren't all scrapping with each other to eke out an existence in a starving world. True peace (which includes peace with all our nonhuman friends) requires we don't do things that will harm wildlife or damage Earth's capacity to feed us all. True peace should make everyone happy; and if you've seen Gitie's and my wild bird website (, you'll know I don't reserve "everyone" just for people.

Review: Heaven+Earth by Ian Plimer

I haven't yet told you all the reasons I personally am convinced we are in deep trouble with the belief that humans are causing dangerous global warming, but luckily there is a book that does so. Ian Plimer is perhaps best known as the geologist who debunked creationism in "Telling Lies for God". Here he turns his attention to the global warming beliefs that are now resulting in huge (possibly disastrous) policy changes by governments in the hope of avoiding "climate change". In "Heaven+Earth", I think Plimer does pretty well.

Once in a World-Time...

Four and a half billion years... half way through the lifetime of a planet... for some of that time molten and dead from bombardment in the early formation of the solar system... for most of the remainder inhabited only by single-celled life forms. And for a 'mere' half billion years, a flourishing of plants and animals. Then at last, for the merest flicker of geological time, there are human beings. How very long it took until a tool-making, syntactic language-using, self-reflecting species arose—for the first time and (for all we know) the only time in the entire galaxy.

But life on Earth is dangerous. Mass extinctions can happen slowly through geological changes that cause vulcanism and planetary cooling, or quickly through a collision with a meteorite. A nearby star could become a supernova. At least twice in its long lifetime, Earth has been frozen solid or nearly solid all the way to the equator—the sort of ice age which, if it happened now, would exterminate all multicellular life. Bacteria would once again be the only life forms. By the greatest of good fortune, our planet has survived until it is within reach of safety from cosmic disasters: its latest creation, ourselves, is slowly maturing in its capacity to develop the means to safeguard the planet for all life.
