NZ Royal Society. Knowledge or ignorance?

Keith Hunter’s statement asserts: The evidence pointing towards AGW comes from multiple independent lines of argument, each pointing in the same direction. … a few examples follow.

This is his second example:

The amount of extra carbon accumulated in the ocean and the atmosphere matches the known quantity emitted by the combustion of fossil fuels.

How can he be so sure, when nobody else is?

NZ Royal Society. Strength or aggression?

Keith Hunter’s statement asserts: The evidence pointing towards AGW comes from multiple independent lines of argument, each pointing in the same direction. … a few examples follow.

This is his first example:

It is a plain fact that human activities have significantly increased the concentrations of greenhouse active gases in the atmosphere, particularly since the mid-20th century.

Who will tell him that nothing could be further from plain? What does he mean by “greenhouse active gases”? Does he mean that water vapour has increased in the atmosphere? Does he include methane? Nitrous oxide? Or does he only mean carbon dioxide?

Does he exclude the possibility that increased temperature has driven more carbon dioxide from the oceans into the atmosphere?

On 8 March, 2010, David Archibald wrote a guest post on WUWT entitled “The Logarithmic Effect of Carbon Dioxide”. This was brought to my attention recently as an article worthy of attention, so here it is.

The greenhouse gases keep the Earth 30° C warmer than it would otherwise be without them in the atmosphere, so instead of the average surface temperature being -15° C, it is 15° C. Carbon dioxide contributes 10% of the effect so that is 3° C. The pre-industrial level of carbon dioxide in the atmosphere was 280 ppm. So roughly, if the heating effect was a linear relationship, each 100 ppm contributes 1° C. With the atmospheric concentration rising by 2 ppm annually, it would go up by 100 ppm every 50 years and we would all fry as per the IPCC predictions.

But the relationship isn’t linear, it is logarithmic. In 2006, Willis Eschenbach posted this graph on Climate Audit showing the logarithmic heating effect of carbon dioxide relative to atmospheric concentration:

The logarithmic relationship between atmospheric CO₂ concentration and temperature forcing. In other words, Willis Eschenbach shows that later increments of carbon dioxide added to the atmosphere have lesser effects on atmospheric temperature.

And this graphic of his shows carbon dioxide’s contribution to the whole greenhouse effect:

John Boscawen has issued a notice which has just reached me. I urge everyone to send it on to family, friends and colleagues. This is your chance to be heard by the government.

Do you want to see all prices rise after July 1?

On July 1, the most pointless tax ever inflicted on New Zealanders will come into force.

It’s called the Emissions Trading Scheme. And it will make not the slightest practical difference to the Earth’s climate.

This is a story on the Emissions Trading Scheme, so I wanted a picture of carbon emissions. But when I was looking, I couldn’t see one, since carbon dioxide emissions are invisible (bit of global warming humour there). This is someone else’s. It’s actually a photo of steam emissions, but because it’s backlit the steam is dark, making it look like carbon, which is black, which makes stupid people everywhere think of carbon dioxide, even though it’s completely transparent, because the eco-mentalists have been showing us these pictures for years. There’s trickery everywhere! Protect yourself — learn the truth!

BUT it will make a HUGE difference to your household budget. Whether you believe in global warming or not, all New Zealanders should be asking why we are the only country in the world to be forcing economy-wide cost increases on all its citizens. For no genuine reason!

Cost increases that will make it harder for our businesses and exporters to compete. And cost essential jobs.

* If you live in Auckland, Hamilton or Christchurch, come to an URGENT PUBLIC MEETING and learn how: *

• The government and power generators will soon be celebrating windfall profits while you’re suffering a 5% price rise.
• Petrol will soon go up 4 cents a litre because of the ETS.
• The above rises will double to 10% and 8 cents a litre by 2013.

• The cost of EVERYTHING ELSE will go up after July 1, as the increased cost of power and transport forces increases across the board.

Hot air being used to lift a hot-air balloon. Since hot air is invisible, it is essential to mention it when present, else it goes unnoticed while lifting the insubstantial into the heavens. Deep, huh?

There’s little of royalty attached to recent climate change missives emanating from the Royal Society. Did I call them missives? I meant to say emissions.

Professor Keith A. Hunter, FNZIC, FRSNZ, Vice-President, Physical Sciences, Mathematics, Engineering and Technology, Royal Society of New Zealand, issued a statement on 7 April entitled Science, Climate Change and Integrity.

He means to support the hypothesis that human activity is dangerously warming the world’s climate. He uses whole sentences and impeccable syntax, but the evidence he cites is wrong.

The package is lovely but the contents rotten.

There are now several of our prominent public scientists who are unaware it is not sufficient merely to tog themselves out in the royal or other esteemed branding — they must actually live up to it and, before all else, speak the truth.

The senior scientists who’ve made misleading public statements about global warming include Peter Gluckman, David Wratt, James Renwick, Brett Mullan, Andrew Reisinger and Jim Salinger.

Their cheeks are smooth and their mouths are smiling but their breath stinks. Read more… »
