I knew it was missing something!

It's officially known as a report on the "Measurement of the Duration of a Trendless Subsample in a Global Climate Time Series." In lay-speak, it's a study of just how long the current pause in global warming has lasted. And the results are profound:

According to Canadian Ross McKitrick, a professor of environmental economics who wrote the paper for the Open Journal of Statistics, "I make the duration out to be 19 years at the surface and 16 to 26 years in the lower troposphere depending on the data set used."

In still plainer English, McKitrick has crunched the numbers from all the major weather organizations in the world and has found that there has been no overall warming at the Earth's surface since 1995 - that's 19 years in all.

During the past two decades, there have been hotter years and colder years, but on the whole the world's temperatures have not been rising. Despite a 13 per cent rise in carbon dioxide levels over the period, the average global temperature is the same today as it was almost 20 years ago.

In the lower atmosphere, there has been no warming for somewhere between 16 and 26 years, depending on which weather organization's records are used.

Not a single one of the world's major meteorological organizations - including the ones the United Nations relies on for its hysterical, the-skies-are-on-fire predictions of environmental apocalypse - shows atmospheric warming for at least the last 16 years. And some show no warming for the past quarter century.

This might be less significant if some of the major temperature records showed warming and some did not. But they all show no warming.

Even the records maintained by devoted eco-alarmists, such as the United Kingdom's Hadley Centre, show no appreciable warming since the mid-1990s.

Despite continued cymbal-crashing propaganda from environmentalists and politicians who insist humankind is approaching a critical climate-change tipping point, there is no real evidence this is true.

There are no more hurricanes than usual, no more typhoons or tornadoes, floods or droughts. What there is, is more media coverage more often.

Forty years ago when a tropical storm wiped out villages on a South Pacific Island there might have been pictures in the newspaper days or weeks later, then nothing more. Now there is live television coverage hours after the fact and for weeks afterwards.

That creates the impression storms are worse than they used to be, even though statistically they are not.

While the UN's official climate-scare mouthpiece, the Intergovernmental Panel on Climate Change (IPCC), has acknowledged the lack of warming over the past two decades, it has done so very quietly. What's more, it has not permitted the facts to get in the way of its continued insistence that the world is going to hell in a hand basket soon unless modern economies are crippled and more decision-making power is turned over to the UN and to national bureaucrats and environmental activists.

Later this month in New York, the UN will hold a climate summit including many of the world's leaders. So frantic are UN bureaucrats to keep the climate scare alive they have begun a worldwide search for what they themselves call a climate-change "Malala."

That's a reference to Malala Yousafzai, the Pakistani schoolgirl who was shot in the head by the Taliban after demanding an education. Her wounding sparked a renewed, worldwide concern for women's rights.

The new climate spokeswoman must be a female under 30, come from a poor country and have been the victim of a natural disaster.

If the facts surrounding climate-disaster predictions weren't falling apart, the UN wouldn't such need a sympathetic new face of fear.

I agree with a lot of this.

What I'd dispute is whether we know know for certain it is largely man-made. Again I would defer to NASA where it specifies it is "very likely due to human activities" that is the consensus. I study statistics and the hypothesis/ significance testing you could perform to test time periods before and after human activity would be very rigorous in determining a trend change, and there is certainly no lack of data.

As far predicting the benefit/harm and the most cost effective policy alternative if one is required, I agree it's debatable. There are organisations such as the Copenhagen Consensus that argue for technology based solutions such as stratospheric aerosol injection or carbon capture rather than pure taxes/reduced emissions.

My own (layman) take here is that mitigating a potentially large unknown is pragmatic. At the very least until such technologies are proven to be effective and feasible in reversing the trend. European colonists destroyed ecosystems through introducing but a handful of non-native species to a previously isolated habitats. I think it goes without saying we should not be naive about the unforeseen impacts of a global change like this and taking a conservative approach is warranted.

I'm not saying that "climate change" isn't "real," but that the practice of climate science is highly prone to fraud and conflates natural science with social science.

This matters because one could accept climate change on the basis of natural science but still reject it on the basis of social science given the understanding that the policies normally associated with environmentalism are clearly not the proper ways of addressing the effects of climate change.

As such, there is a lack of scrutiny in much of the discourse about and around climate change (to say nothing of the ridicule and mockery and epithets that are slung on "both" sides). There are a few separate questions worth addressing:

1. Is the planet getting warmer?
2. If it's getting warmer, is it anthropogenic (human-caused)? (If not, then it's unclear how humans can 'reduce' it and/or deal with the consequences.)
3. If it's getting warmer, by what magnitude? (This is a scientific question with many implications for policy.)
4. What are the costs of climate change? (Oft asked/answered)
5. What are the benefits of climate change? (Might it, say, make the arctic habitable and a source of land or food? Might it bring down the costs of heating homes/businesses in colder climates?)
6. Do costs outweigh benefits or vice versa? (This question, while important, is based less on scientific fact than on interpersonal value and depends heavily on the results of the scientific questions above. As such, public policy is based on facts and values, and does not translate science directly into policy.)
7. If costs outweigh the benefits, what policies are appropriate? (This, again, would be determined by the matters of both fact and value -- natural science and social science.)
8. What are the costs of the policies designed to reduce the costs of climate change? (Might the policies imposed to address the costs of climate change have associated costs that may outweigh their potential benefits? Might reducing the effects of global warming slow the economic growth so as to impoverish half the planet, or imbuing powers to governments that're likely to be used in ways having little to do with climate change? Such costs might have grave and devastating effects that far outstrip their potential benefits to say nothing of the perceived costs of climate change, itself.)

This is a social scientific question that is no less important than the natural scientific questions listed above. There are many more questions in addition to these, but this is perhaps sufficient to make my points:

* It's possible to accept the natural science of climate change, but reject the policies proposed to combat it.
* It is possible to think that climate change is anthropogenic, but to humanely conclude that nothing should be done about it.

However unpopular it is (on videosift especially) to dissent to the claims that anthropogenic climate is "real," it should be noted that such dissent does not, de facto, "deny" the science, but does, instead, take a far more considered approach that accepts the natural science in light of its many social scientific implications.

I don't know how to get around the paywall ... But even so, fair enough I assume that the first paragraph is accurate. Does that say that global warming is no longer a threat?

The editorialising of the WSJ in the second paragraph certainly does, but given they haven't quoted the UN in their assertion that "global warming has stopped since shortly before this century began", I assume it is just that, unsubstantiated opinion from pundits who are not experts on the subject (and by stopped it's clear what they're implying is 'no longer a threat' not, a temporary pause).

Has the UN come out and said that they believe action against climate change is a waste of money? Have the many scientific organisations studying this, and surely aware of the latest developments changed their position? If not, then it's likely because in the long term, the prognosis hasn't changed.

From the WSJ:

"The U.N. no longer claims that there will be dangerous or rapid climate change in the next two decades. Last September, between the second and final draft of its fifth assessment report, the U.N.'s Intergovernmental Panel on Climate Change quietly downgraded the warming it expected in the 30 years following 1995, to about 0.5 degrees Celsius from 0.7 (or, in Fahrenheit, to about 0.9 degrees, from 1.3).

"Even that is likely to be too high. The climate-research establishment has finally admitted openly what skeptic scientists have been saying for nearly a decade: Global warming has stopped since shortly before this century began."

The usual to get around paywall.

I'm not an expert on climate change and I assume you have not devoted your life to climate science either.

From what I can ascertain, your links suggest a hiatus in warming not a reversal of trend.

To quote the BBC link:

"Prof Tung believes that whatever the cause and the length of the pause, we are on a "rising staircase" when it comes to global temperatures that will become apparent when the Atlantic current switches again.

At the end we will be on the rising part of the staircase, and the rate of warming there will be very fast, just as fast as the last three decades of the 20th Century, plus we are starting off at a higher plateau. The temperatures and the effects will be more severe."

And the LA Times link:

"Climate skeptics have pounced on this apparent discrepancy, citing it as proof that climate change isn't real, or at least that scientists don't completely understand it. But those who study Antarctic sea ice say their curious observations shouldn't shake anyone's confidence. Dramatic changes in temperature, sea level and extreme weather around the world are proof enough the planet is warming, they say; the only question is how these changes affect the Antarctic as they ripple through the climate system."

Again, I'm no expert. I don't presume that casual Internet research will enable me to properly evaluate and scrutinise academic articles and accurately assess their value within the broader rationale for acting against the purported harm caused by climate change.

Which is why I defer to organisations of scientists. If they overwhelmingly continue to believe that climate change is a threat, then so do I. If they change their views, so will I.

Why is this not the most reasonable approach?
