Will the AMO Save Arctic Sea Ice?

Skepticism, , , , , , , , ,

According to Michael Mann he coined the name “Atlantic Multi-decadal Oscillation”:

Two decades ago, in an interview with science journalist Richard Kerr for the journal Science, I coined the term the “Atlantic Multidecadal Oscillation” (the “AMO” for short) to describe an internal oscillation in the climate system resulting from interactions between North Atlantic ocean currents and wind patterns. These interactions were thought to lead to alternating decades-long intervals of warming and cooling centered in the extratropical North Atlantic that play out on 40-60 year timescales (hence the name). Think of the purported AMO as a much slower relative of the El Nino/Southern Oscillation (ENSO), with a longer timescale of oscillation (multidecadal rather than interannual) and centered in a different region (the North Atlantic rather than the tropical Pacific).

More recently Mann et al. claimed that in actual fact the AMO does not exist.

For several decades the existence of interdecadal and multidecadal internal climate oscillations has been asserted by numerous studies based on analyses of historical observations, paleoclimatic data and climate model simulations. Here we use a combination of observational data and state-of-the-art forced and control climate model simulations to demonstrate the absence of consistent evidence for decadal or longer-term internal oscillatory signals that are distinguishable from climatic noise. Only variability in the interannual range associated with the El Niño/Southern Oscillation is found to be distinguishable from the noise background.


More recently still I discovered the source of Matt’s optimistic, AMO based prediction of Arctic sea ice recovery. Here is the latest edition, courtesy of Roger “Tallbloke” Tattersall:

What’s Up With That Arctic Sea Ice Disinformation

Satire, , , , , , , , , , , , , ,

A few days ago we posted an article about the recent surge in the amount of disinformation being published about Arctic sea ice. Eventually one of our long list of usual suspects, Anthony Watts, published a copy of an erroneous Arctic article by Paul Homewood.

Now the Watts Up With That Arctic porky pie production line is going into overdrive, so here’s an already long list of its output in the run up to the COP26 conference in Glasgow in a month or so. First up is the aforementioned clone from NALOPKT. Allegedly:

It is very easy to show that Arctic sea ice has stabilised. As their graph itself shows, there have only been three years since 2007 with lower ice extent than that year, and eleven have had higher extents. Also the average of the last ten years is higher than 2007’s extent.

In itself, this is too short a period to make any meaningful judgements. But that is no excuse for the Met Office to publish such a manifest falsehood.

This comment of mine on that article remains invisible at WUWT:

This morning (UTC) I added another comment to Anthony’s moderation queue:

The Great White Con 2015 “New Einstein” Award

Satire, , , , , , ,

As regular readers will have realised by now, we are subject to a continuing barrage of verbal abuse as we fearlessly pursue our goal of telling the truth about the Arctic whatever the obstacles. Following the latest such episode we have consulted our learned counsel and decided to publish the spiciest episodes here. By the time August 2015 draws to a close a poll of our loyal reader(s) will determine which of our utterers of undeleted expletives will be awarded a wild card entry into the 2015 Great White Con Arctic Basin Big Wave Surfing Contest.

Here are the contestants so far this year:

1) Tony (“Steve Goddard”) Heller, with:

I’m amazed you have the gall to show up around here, after saying I should be jailed for accurately reporting and predicting Arctic ice.

Pathetic and quite psychotic Jim. And the NASA press release said nothing about uncertainty or satellites.

World class wanker

 

2) David (“Climate of Hate“) Rose, with:

3) Roger (“TallBloke”) Tattersall, UKIP’s Yorks and North Lincs Energy and Climate Change spokesman and prospective parliamentary candidate for Pudsey, with:

 

4) Gail Combs, regular commenter at unReal Science amongst other places, with:

Jim, How does it feel to be morally responsible for the deaths of thousands of people a year?


Please feel free to speculate about the ultimate outcome of this exciting new competition in the space provided for such purposes below!
