More ice in scary melting

Arctic ice

The Associated Press chills our blood again with a story on record Arctic sea ice melting.

Arctic sea ice melted this summer to the second lowest level since record-keeping began more than 50 years ago, scientists reported Thursday, mostly blaming global warming.

“This is not a random event,” said oceanographer James Overland of the U.S. National Oceanic and Atmospheric Administration. “It’s a long-term change in Arctic climate.”

Only in 2007 was there less summer sea ice, which has been dramatically declining since scientists began using satellites to monitor melt in 1979.

So, unless I’m mistaken, in each of the last four years there has been more ice than there was in 2007. That sounds like a recovery — it’s certainly not getting worse. Continue Reading →

Miraculous: computer game finds missing heat

From today’s Summit County Citizen’s Voice, we read Bob Berwyn’s account of Kevin Trenberth’s favourite paper so far this century.

Global warming: ‘Missing’ heat found deep in the ocean

Changes in ocean currents and circulation are capturing some of the sun’s incoming heat deep in the ocean, according to researchers with the National Center for Atmospheric Research, who said their latest computer models account for some of the global warming heat that’s “missing” from land and sea surface temperature readings.

This implied that heat was building up somewhere on Earth, according to a 2010 study published in Science by NCAR researchers Kevin Trenberth and John Fasullo.

Observations from a global network of buoys showed some warming in the upper ocean, but not enough to account for the global build-up of heat. Although scientists suspected the deep oceans were playing a role, few measurements were available to confirm that hypothesis.

To track where the heat was going, Meehl and colleagues used a powerful software tool known as the Community Climate System Model, which was developed by scientists at NCAR and the Department of Energy with colleagues at other organizations.

Well, well, who would have thought? All the missing heat, safe in the ocean deep, alive and well, having nipped through the upper reaches of the ocean without warming it. I never guessed — did you? Truly amazing.

But there’s no data, just more modelling

The computer game doesn’t care about realism, so the lack of any plausible mechanism whereby the heat might have reached more than 1000 ft (305 m) deep while leaving the upper levels unwarmed didn’t affect its findings.

When the game “found” extra heat deep in the ocean, there was nothing to say “that’s impossible.”

So, because they’re real scientists, we can expect an announcement very soon of a new study aimed at discovering how the missing heat got to where it was found.

One day they’ll get around to actually observing the climate effects they report. When they do, you can read about it here!

NIWA’s web site a revelation

NIWA's logo

 

NIWA has an interesting web site which they change frequently. One must visit often to keep up with the changes, because NIWA never sends one a memo.

There’s a section under Climate called “NZ temperature record” where you can see the latest version of the seven-station temperature series.

I think the judge supervising our application for judicial review would be keen to know that what NIWA solemnly pledged to the Court was not the “official or formal New Zealand temperature record” is in fact named on its web site in effectively that very manner.

For taking the words “NZ temperature record” in their most natural meanings, without strain, one understands that NIWA is presenting to the public the very thing it promised the judge it does not have. Continue Reading →

Suddenly everyone hates farming

Few people admire farming as we once did when we understood where this country’s wealth was created. On the contrary, farming has come under sustained attack, and from none more strongly than the National Party, once almost a fellowship of farmers and the industry’s staunchest supporter. Now our formerly admired farmers must tolerate the impending ETS tax on ruminant eructation, which farmers are helpless to reduce, yet for which they are further harassed by the modern epithet of “emitter”. As though those clean, natural gases could pollute the environment that has been creating them in vast quantities for millions of years. The “carbon tax” is a significant imposition, yet it’s hardly remarked upon except by those who strive to get it noticed and repealed — or others, apparently more numerous (certainly more vocal and popular with the media), who would gladly see it increased. The Coalition here rails against the unreasonable burden of an ETS which purports to “fight” in our name against so-called “anthropogenic global warming”. Do we still call it that? I guess this month’s stupid synonym is “climate disruption.” But since climate never goes for long without disruption the term defines tautology — how completely brainless to then declare it a crime and seek a culprit.

NZ farming remains at threat from ETS

“New Zealanders know that their prosperity relies heavily on the farm sector” says the Hon Barry Brill, chairman of the New Zealand Climate Science Coalition, “and yet the biggest threat to the future of farming is an attack by our own Government. Continue Reading →
