It’s about time to review the evidence for man-made global warming

\ 22 Comments \ by
From my colleague and good friend John McLean, of Melbourne, comes a penetrating discussion about evidence that’s long been missing from science, let alone the unmoderated disputes in the global warming branch of science. His sixth paragraph is surgically astute. I will have a contribution in this area ready soon. – RT

Some people seem to think man-made global warming has been proven. Others believe there’s no evidence that man-made warming exists. Neither is correct. Evidence exists, but, as people familiar with courts of law will know, what’s submitted as evidence is not automatically proof. Continue Reading →

TV One sinks into climate swamp – Friday

CLOUDS – water vapour (think steam); non-polluting, non-toxic, form on micro-particles, make fantastic animals and shapes

— by John McLean

TV One managed to plumb new intellectual depths last Friday when it tried to associate photo-chemical smog and micro-particle emissions in urban areas with carbon dioxide and other greenhouse gases. It frequently displayed images of real air pollution. Continue Reading →

TVNZ’s medley of climate nonsense – Thursday

\ 18 Comments \ by

Drought — the big dry

• Guest post •

— by John McLean

TV One’s great “climate change” campaign continued last Thursday, featuring a medley of nonsense about “extreme events” and New Zealand’s future scorching temperatures before sounding off about Donald Trump’s foolishness in withdrawing the USA from the Paris Climate Agreement. As we have come to expect, TVNZ was wrong on each point. Continue Reading →

Beyond a joke — this must stop!

It’s Tuesday evening and TV One isn’t improving. This time it claims that climate refugees will be leaving Kiribati due to rising seas, caused by man-made climate change, and heading to New Zealand where, surprisingly, the new government is preparing to issue ‘climate refugee’ visas.

McLean reveals IPCC confessions

\ 12 Comments \ by
John McLean is a PhD candidate, climate researcher, computer scientist and IPCC reviewer and lives in Melbourne. He has long made thoughtful and informed contributions to the debate on dangerous man-made global warming (DAGW). Two weeks ago I received a copy of a letter he had sent to the Dominion Post in Wellington concerning the spat between Carter and Leyland, Hot Topic and Wratt, Reisinger and Renwick (WRR). The letter contained startling revelations from the latest IPCC Assessment Report, AR5, and John kindly agreed I could publish them, though they’re new only to me. As far as we know the letter was not published. His letter takes its facts from an article he wrote for Quadrant Online last year. – RT

Oddly, NIWA scientists conceal them

UPDATE 1: 28 Mar 1300 NZDT, see below.

John’s letter refers to the WRR article Human role in climate change is clear. The following are excerpts from the AR5 then the WRR article (emphasis added). Notice the stinging observation that WRR failed to disclose what was inconvenient for the IPCC to say, because it contradicted the alarming sounds of doom. Continue Reading →

How the IPCC writes its own ticket

The end of this week (March 15) marks the cut-off for scientific papers if they are to be cited in the Working Group I contribution to the forthcoming IPCC Fifth Assessment Report, due in 2014. Unless the papers are published or accepted for publication the report cannot refer to them. The final expert review of the draft document ended on November 31, 2012, some 15 weeks ago. But according to IPCC procedures, the draft document can still be modified to accommodate new papers.

Newspapers

This is an adopted article.

You might reasonably wonder what’s going on, especially when the IPCC claims that its report is comprehensively reviewed by experts. To borrow the catch phrase beloved of ads for “miracle” knives and so much of the other schlock merchandise sold on late-night TV: but wait, there’s more! Continue Reading →

It’s not warming, you nitwit — it’s cooling

icicles in Germany

Recent domestic icicles in Germany brought on by the mind-altering greenhouse gas, CO2.

All right, so it might not be getting down to out-of-the-ordinary freezing temperatures, but it’s certainly not unduly warm, which is the claim we’re constantly hearing in the mainstream media, even now. Even after all the contrary evidence. Here’s more.

To show that there is scientific data backing up the refutation of strong, even dangerous, warming brought on by our over-indulgence in the famous capitalist mind-altering industrial pollutant, carbon dioxide, the NZ Climate Science Coalition just issued a press release. The 2009 paper from McLean, de Freitas and Carter shows the uncanny correlation between the Southern Oscillation Index and global temperature several months later. The press release shows how the paper “predicts” the current temperature plunge.

And I really mean plunge, because McLean et al speculate this year could be the coldest since 1956. Brrr!

Now be my guest: show how wrong it is! Show us how the correlation is not really a correlation. It’s a free world!

Oh — and you’ll also have to demonstrate, of course, that global temperatures are NOT following the SOI graph from about seven months ago (please don’t forget that part). The press release is next. Continue Reading →

More proof global temps lag SOI

SOI forecast January 2011

Bryan Leyland’s latest graph (January 2011) showing the implied SOI forecast (thick pink line) of global temperatures for late 2010. Click for larger version.

NIWA, listen to this, it’s amazing

UPDATE 1, 11 JAN 2011, 09:30 NZDT

On December 1 last year, we wrote about Bryan Leyland’s prediction of significant cooling before the end of the year coming true. You can see from the chart exactly what happened. Not only that, it would appear that the temperature has not finished going down yet.

This remarkable forecast, now some eight months old, comes out of a 2009 paper showing a lagged correlation between global temperatures and the Southern Oscillation Index (SOI), calculated from fluctuations in the air pressure difference between Tahiti and Darwin, and indicative also of the start (and the state) of a La Nina (as now) or an El Nino. This correlation is a lot more convincing than comparing global temperature with CO2 levels! Continue Reading →

Nature, not man, responsible for recent global warming

\ Leave a Comment \ by

Now the cat is put among the pigeons.

Research recently completed by two Kiwis and an Aussie reveals that natural forces are the dominant influence on climate. They say little or none of the late 20th century global warming and cooling can be attributed to human activity. Continue Reading →
