Bemærkelsesværdige citater.....

..the ice cover this spring shows an unusually large proportion of young, thin first-year ice; about 30% of first-year ice typically survives the summer melt season, while 75% of the older ice survives.

For a simple estimate of the likelihood of breaking last year's September record, we can apply survival rates from past years to this year's April ice cover. This gives us 25 different estimates, one for each year that we have reliable ice-age data (see Figure 2).

To avoid beating the September 2007 record low, more than 50% of this year's first-year ice would have to survive; this has only happened once in the last 25 years, in 1996.

What irony. I am a passenger on one of the most powerful icebreakers in the world, travelling through the Northwest Passage - which is supposed to become almost ice-free in a time of global warming, the next shipping route across the top of the world - and here we are, stuck in the ice, engines shut down, bridge deserted. Only time and tide can free us.

Det bidende grønlandske vintervejr understreges af en ny officiel kulderekord for februar i Kangerlussuaq. Den 10. februar klokken 18 UTC nåede termometret ned på minus 46,8°C. Den - på dagen og timen - 24 år gamle rekord lød på minus 46,4°C. Det absolut laveste DMI har målt i Kangerlussuaq er minus 47,2°C den 4. januar 1983, men data-serien er ikke så lang. Tidligere skulle en amerikansk station i området have målt tempetaturer under minus 50°C!

Final results: Among 1292 voters, 64% think that it's because the greens are wrong and one can't defend wrong statements well; 18% think that they're overwhelmed by their "religion" or big ideas and can't see and learn the "details"; 9% think that they're obsessed with the change that prevents them from seeing the status quo (the previous two groups have twenty-seven percent in total); 5% think that the greens are not under the same pressure that forces the skeptics to be good to survive; 4% think that the greens are more ignorant or more stupid; 1% think that the greens have less at stake; 0% or 2 participants think that the greens are less passionate.

Vi må med andre ord holde op med at stille spørgsmålstegn ved, om den globale opvarmning er en kendsgerning, og om mennesker i givet fald er de skyldige. Den snak er for længst passé i klimaforskerkredse

The unfortunate reality of the situation is that we are not making progress

"We've realigned the observations and as a result the models agree with the observations much better than previously,"

For præcist 20 år siden sagde jeg her i Kongressen, at det er 99 pct. sikkert, at de globale klomaforandringer er forårsaget af menneskelige aktiviteter. Det standpunkt står jeg stadig fast ved. Det eneste, som har ændret sig siden 1988, er, at vi har langt mindre manøvrefrihed end dengang.

We believe that the protection of life on Earth is a profound moral imperative. It addresses without discrimination the interests of all humanity as well as the value of the non-human world. It requires a new moral awakening to a compelling demand, clearly articulated in Scripture and supported by science, that we must steward the natural world in order to preserve for ourselves and future generations a beautiful, rich, and healthful environment. For many of us, this is a religious obligation, rooted in our sense of gratitude for Creation and reverence for its Creator.

It is a great irony that the melting of the ice cap could give us access to yet more fossil fuels that will accelerate climate change even further.

I suspect the only thing that is going to stop humanity wrecking the planet is when we get hit by some serious ecological disasters, and by then it may well be too late.

I needed to explain the Pacific Decadal Oscillation to this IPCC lead author, who leans heavily on claims that Alaska is melting and who had earlier in the day demanded — on tape — to know what the PDO was.

India is faced with the challenge of sustaining its rapid economic growth while dealing with the global threat of climate change. This threat emanates from accumulated greenhouse gas emissions in the atmosphere, anthropogenically (menneskeskabt) generated through long-term and intensive industrial growth and high consumption lifestyles in developed countries

The persistently low sea ice cover in the area and data from some interesting sources, electronic seal hats [caps worn by seals that provide temperature, depth and position data] seems to suggest that warm water beneath the halocline may be reaching the underside of the Wilkins Ice Shelf and thinning it rapidly - and perhaps reaching the surface, or at least mixing with surface waters

The American Physical Society, an organization representing nearly 50,000 physicists, has reversed its stance on climate change and is now proclaiming that many of its members disbelieve in human-induced global warming.

There is a considerable presence within the scientific community of people who do not agree with the IPCC conclusion that anthropogenic CO2 emissions are very probably likely to be primarily responsible for the global warming that has occurred since the Industrial Revolution.

APS Climate Change Statement.
APS Position Remains Unchanged.

The American Physical Society reaffirms the following position on climate change, adopted by its governing body, the APS Council, on November 18, 2007:

"Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth's climate."

An article at odds with this statement recently appeared in an online newsletter of the APS Forum on Physics and Society, one of 39 units of APS. The header of this newsletter carries the statement that "Opinions expressed are those of the authors alone and do not necessarily reflect the views of the APS or of the Forum." This newsletter is not a journal of the APS and it is not peer reviewed.

National Policy
07.1 CLIMATE CHANGE
(Adopted by Council on November 18, 2007)

Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth's climate. Greenhouse gases include carbon dioxide as well as methane, nitrous oxide and other gases. They are emitted from fossil fuel combustion and a range of industrial and agricultural processes.

The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth's physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now.

Because the complexity of the climate makes accurate prediction difficult, the APS urges an enhanced effort to understand the effects of human activity on the Earth's climate, and to provide the technological options for meeting the climate challenge in the near and longer terms. The APS also urges governments, universities, national laboratories and its membership to support policies and actions that will reduce the emission of greenhouse gases.

... and is now proclaiming that many of its members disbelieve in human-induced global warming. The APS is also spon-soring public debate on the validity of global warming science. The leadership of the society had previously called the evidence for global warming "incontrovertible."

Men hvordan kan det være at jeg aldrig ser dig give din modpart ret i noget som helst? Begge parter er jo af kød og blod og fejler nogen gange

It will no doubt dawn on the APS in due course that the correct response, rather than red-flagging the paper as they have, and rather mendaciously stating that the paper was not peer-reviewed, is to invite an alarmist to tear it to shreds in the next issue. I'm sure that is what will happen, and will be interested to see the extent (if any) to which the demolition of my equations is done ad rem rather than ad hominem.

We are a little late to the party, but it is worth adding a few words now that our favourite amateur contrarian is at it again. As many already know, the Forum on Physics and Society (an un-peer-reviewed newsletter published by the otherwise quite sensible American Physical Society), rather surprisingly published a new paper by Monckton that tries again to show using rigorous arithmetic that IPCC is all wrong and that climate sensitivity is negligible. His latest sally, like his previous attempt, is full of the usual obfuscating sleight of hand, but to save people the time in working it out themselves, here are a few highlights....

I want the public to be very scared by what they see. I want them to see a very bleak future. I want them to feel disillusioned halfway through and feel hopeless.

If we heap contempt on God's creation, that is inconsistent with glorifying God.

The ancient prophet laid the choice before the people. Life or death, blessings or curses. Therefore choose life so both thou and thy seed may live.

The evidence is there. The signal is on the mountain. The trumpet has blown. The scientists are screaming from the rooftops. The ice is melting. The land is parched. The seas are rising. The storms are getting stronger. Why do we not judge what is right?

This is our home. We will make our stand here. It is at risk. It is not ours. The earth is the Lord's, and the fullness thereof.

In particular, we do not observe the large surface warming trends predicted by models; indeed, we detect significant surface cooling trends over the western Arctic Ocean during winter and autumn. This discrepancy suggests that present climate models do not adequately incorporate the physical processes that affect the polar regions.

Some skeptics of global warming have also suggested that the melt is part of a cyclical process. Flat out wrong, says Serreze. He explains, "It's not cyclical at this point. I think we understand the physics behind this pretty well. We've known for at least 30 years, from our earliest climate models, that it's the Arctic where we'd see the first signs of global warming."
Serreze says, "It's a situation where we hate to say we told you so, but we told you so.

If the ice were melting, then the ice cover would be retracting, not expanding and breaking off. The fact that ice is being pushed into the sea means that there is pressure behind the ice, usually from precipitation [snow], piling up and forcing the ice out, where it eventually breaks off into the sea. The same thing happens when a glacier expands: a build up of ice pressure pushes the glacier out.

This is indicative of cooling, not warming.

It is impossible to reason a person out of positions they have not been reasoned into.

It doesn't help that NASA scientist James Hansen was one of the early alarmists claiming humans caused global warming. Hansen is a political activist who spreads fear even when NASA's own data contradict him.
