Happy Easter Unthreaded

Yes, incredibly, I am on a real holiday. Happy Easter to you all. I am at the beach again.

The site will be going on a holiday too. So sometime this break unfortunately we’ll be offline.  Sorry about that.

Do book those Delingpole tickets.

Satellites show a warmer Earth is releasing extra energy to space

(I’m revisiting older important papers and setting up resource pages, largely thanks to Tony Cox’s prodding. In this post I found it interesting that Lindzen’s work, which was so controversial because it proved the IPCC is wrong, was in many ways merely confirming earlier results. — Jo) Guest Post: Tony Cox and Jo Nova Satellite measurements agree with the ocean heat content measurements. As the Earth warms, more radiation escapes to space.

If feedbacks are positive (as the IPCC estimates), then as the Earth warms the amount of energy being radiated to space will shrink (thus warming the Earth even further). If feedbacks are negative, as the Earth warms more energy will radiate away.

Multiple studies show that feedbacks are negative.

Lindzen and Choi analyzed short periods of warming looking for changes in the outgoing long-wave radiation leaving from the top of the atmosphere. The satellite observations show, repeatedly, that as the Earth warms, the climate system shifts and lets more of the infra red or long-wave energy out to space.[1],[2] It’s like a safety release valve. This means that the system has negative feedbacks (like almost all known long-lived or stable natural systems). The changes dampen the effects of [...]

Regulators wet dreams of controlling you

The Planet Under Pressure conference has brought out the clawing powermongers. The Commentator.com team who were brave enough to attend, tell us that no one got very excited about the science, but the word “regulation” was received, well… ecstatically.

The conference was largely focused on how scientists and activists can coalesce to deconstruct the Western way of living and moving to something entirely different, where economic growth and wealth creation is abandoned and replaced, instead, with sustainability targets, trade barriers, regulation and taxation. Indeed there were numerous occasions during the main sessions whereby even the mention of the word ‘regulation’ was met with rapturous applause.

See? The “regulating class” name fits them to a tee.

They have given up on reasoned debate and instead are fomenting a revolution.

According to Lord Anthony Giddens – a preeminent sociologist and speaker at the conference – it means that now is the time for an “activist civil society” to move away from the Western way of life which has proved “too destructive” and toward a radical utopia (read, communes) – all part of what he terms a renewed assault on global warming sceptics.

We can laugh at them, but as Marc Morano points [...]

James Delingpole on Tour in Australia — Book Now!

The brilliant James Delingpole is coming to Australia thanks to the IPA to promote freedom for the world, to rescue modern science and to sell a hundred thousand copies of his new book: Killing the Earth to Save It (How Environmentalists are ruining the planet, destroying the economy and stealing your jobs). He is visiting Perth, Adelaide, Melbourne,  Sydney, and  Brisbane. If you don’t know who James Delingpole is, all I can say is Where Have You Been?

Delingpole is devastating. His disarming honesty, outrageous anecdotes and wide ranging research makes for an ripping read that combines politics, science, money in ways only Delingpole can. His quips paralyze the most excessively pious and drown pomposity with cold common sense.

He has a knack for getting to the heart of the matter, and usually with a poleaxe. I’d heard a lot about Agenda 21, but I didn’t know why it mattered or where it came from until I read Killing the Earth…”

James Delingpole -  one of the worlds most popular, most irreverent libertarian commentators. His twitter bio says: I’m right about everything.  He pulls no punches, and tells it like it is.

Guaranteed to be eye-opening, though provoking, and [...]

The end of the Global Warming Scare would look a lot like this

Soon, the moment will come when the crowd will say “I always knew it was fake”.

Here are three signs we are at the beginning of The End.

1. Op-Ed writers will be pointing out how governments are unwinding  policies: Dominic Lawson: Britain Has Finally Rejected The Bogus Economics Of Climate Change. Germany (home of half the worlds solar energy production)  is winding up its pursuit of renewables, and eight Eastern European nations said “No Thanks” (legally) to the EU’s authoritarian dictat on carbon emissions, and hardly anyone complained…

And which energy source is ecologically correct Germany now developing faster than any other? Lignite, otherwise known as brown coal, the most carbon- intensive fuel known to modern man.

This makes the countries on the European Union’s eastern borders (notably Poland, for which indigenous coal is a dominant energy source) even more reluctant to accept the national emissions targets promoted by Brussels. Eight of these nations launched a legal challenge and last week they won a ruling by the European Court of Justice that Brussels had exceeded its powers in imposing such limits. The court brushed aside the European commission’s complaint that it would not otherwise be [...]

The new world order – Black, Brown, and Soviet-red all over.

Scoff scoff scoff.  There is no global conspiracy to get One World Government. If there was, the leaders would have sent a memo to Bob Brown to be quiet, to Scientific American to rephrase the agenda, and to Richard Black to stay out of group photos at socialist events. So there is no central command, no invisible patriarch who pulls all the strings. But clearly there is a whole class of people who “know” what you need better than you do, and they know you need more governing. The regulating class. Shhhh.

First, the red shade of Black

Blacks Whitewash* has caught Richard Black (paid by the British taxpayer to be an impartial science reporter) taking an active part in a meeting of people who want to influence government policies. Quoting BlacksWhitewash:

“So the Outreach Group advises UNEP and it looks at how unelected NGO’s can better use the information within the GEO reports to pressure Governments. In the Network 2015 document there is a photo of the Outreach Group at the San Sebastian meeting:

There, behind a Felix Dodds and an Esther Larranaga, is Richard Black,  BBC journalist, a publicly funded broadcaster with a duty to remain impartial, [...]

Idso 1998 – eight different ways to show CO2 will have little effect

Here’s a forgotten paper that deserves more attention: Idso 1998.

Rather than using an enormously complex global circulation model (or 22) to come up with a figure for climate sensitivity, Sherwood Idso does calculations from eight completely different natural experiments which all arrive at similar figures. In short, he reviewed 20 years of work to arrive at a prediction that if CO2 is doubled we will get 0.4°C of warming at most, and even he admitted, it might be an overestimate. Basically by the time CO2 levels double, he says we ought expect 0 – 0.4°C of warming, after feedbacks are taken into account. Idso started off assuming that the feedbacks were largely positive, but repeatedly found that they were negative.

Idso’s approach was novel. Instead of climate sensitivity to CO2, he estimates the sensitivity of the Earth to any factor. He calls it the “surface air temperature sensitivity factor“. Once something known heats or cools the Earth, how much do the net feedbacks amplify or dampen that initial change? Rather than trying to measure and capture every single feedback and process, and then calculate the end results, Idso finds situations where he can isolate a factor and calculate [...]
