If you have a volume of Nitrogen (75%) and oxygen (25%) at a nice steady 288K you will see no radiated IR as those two gases are non-radiative. If you added say 400ppm Carbon Dioxide to that gas mixture it would radiate IR as Carbon dioxide is a radiative gas. This is happily quoted for the upper atmosphere but seems to be disregarded in the Mickey Mouse diagrams from Trenberth. It could be some of his missing heat.

Die kalte Sonne reports: Floods in northern Italy occurred preferentially at times of low solar activity. Google translation: The short increases in flood frequency in the early and middle Holocene are triggered by cold phases. At a scale of hundreds of years, changes in flood frequency can be associated with long-lasting climatic changes such as the Neoglazial and the Little Ice Age...

He'll not be getting custard creams with his coffee in the canteen after that one. as you say, must be a real "billy no-mates" at the Beeb; be a great replacement for the Met's Julia Slingo OBE when she finally gets pensioned off...

Another impressive coronal hole. If climatologist Eric Posmentier (Long Island University's Brooklyn Campus), solar physicists Willie Soon, Sallie Baliunas (Harvard-Smithsonian Center for Astrophysics) and physicist Pius Okeke are correct, the recent increase in the numbers of coronal holes could result in a drop of the Earth's globally averaged temperature: Link: www.sciencedaily.com/releases/2000/03/000315080417.htm

The interesting part is the top line where they claim that Sudden Stratospheric Warmings are a 'driver of cold weather'. This is very strange terminology as an SSW is a breaking wave in the tropopause which is more like a lava lamp than a defined boundary. What they need to do is to find out the 'driver' of the SSW. This is normally ascribed to orographically formed Rossby waves in the vertical plane running poleward along and 'breaking' the tropopause. Rossby waves are waves in the motion of a fluid caused by interaction with slower moving fluid or objects. There is a nice description of SSW but coming at the problem from another direction here . So what then causes the change in wind direction that leads to vertical Rossby waves from the Himalayas becoming SSW events at the pole? Well a meridonal jetstream with large lateral Rossby waves where the jetstream runs across Tibet. What causes the meridonal jetstreams? The reduction in the Sun's output in the shortwave and UV region leading to less heating of the oceans at the tropics less convection in the troposphere and various Ozone effect in the stratosphere leading to further cooling. So we are back to the Sun again. Eventually it will have to be accepted.

Interesting read; a couple of paragraphs stood out: The idea for “Global Crisis” first occurred to Parker nearly 40 years ago, when he heard a radio interview with solar physicist John A. Eddy, who had discovered that the reign of Louis XIV, from 1643 to 1715, coincided with a unique solar phenomenon: a lack of sunspots. (Scientists believe the lack of sunspots contributed to the Little Ice Age.) Eddy mentioned that this was particularly interesting because during this period “there were some wars, and some revolutions,” Parker recalls. “And I thought, yeah, some! That’s an understatement.”Livingston & Penn's prediction, inferring that sunspots will disappear by 2015: Dr Habibullo Abdussamatov's (head of the Pulkovo Observatory in St Petersburg, and also the Director of the Russian segment of the International Space Station) forecast: While the book is set squarely in the 17th century, it’s intended as a cautionary tale. And it also offers a lesson about what seems to have worked: Parker finds that survival often hinged on the willingness of central government to take action, coercively or not. “Here’s the evidence,” Parker says, “that climate really does matter, and we need to prepare.”Are any of the Northern Hemisphere governments considering the potential implications of a new solar minimum?

Interesting historical piece from the NoTricksZone: Imagine that it has hardly rained over the last 11 months. The leaves fall drown from the trees in the middle of the summer, cattle die of thirst, forest fires rage. You can walk far into Lake Constanz like during a very dry winter, the Rhine dwindles to a creek. The water boils. When did that happen? In 1540. An almost one-year long drought, from Toscana to the north German border, from France to Poland. A blanket of smoke from the burning forests covered the continent, just like we saw in Russia in 2010. Then came the anti-summer in 1588: It rained and storms raged during 88 of 92 days. The grape harvest could fit in a hat. We had never seen such a summer, wrote the admirals of the Spanish Armada, it was like the British fleet that struck back then in the English Channel. Who were to blame? Humans of course, female witches to be precise; historians estimate that from 1430 to 1650 in Europe 60,000 women were executed. Just how much CO2 does a cauldron emit?

Sigurdur, could I assume you agree with this: "...All over the countries of the world there is a fear of central government. It’s not unjustified. But when it comes to preparing for climate change, only big government has the resources to act in advance. That’s the dilemma we face" It´s clear that climate change or shifts -not meaning "weather" shifts but talking about larger-longer trends shifts- is part of Nature beyond any mankind influence, but the question or dilemma remains the same...

Cuttydyer, Spanish king Felipe II sadly said: "No mandé a mis naves a luchar contra los elementos" (I did not sent my ships to fight against weather elements?" but this was not completely truth: "Philip, who was styled King of Naples and King of Jerusalem by his father, was given the title King of England. However, he hated everything about England - the climate, the food and the people. A little over a year after the marriage to Mary, he left and returned to Spain. Mary saw him only once more, for a few weeks, in 1557. In 1588 as King of Spain, he organised the Spanish Armada with two objectives in mind - to re-establish Roman Catholicism in his former wife's Kingdom and in Holland, and to protect Spanish trade with America. On 28th July, a Spanish Armada (fleet) of 130 vessels sailed up the Channel. The English fleet had faster ships and guns with longer range and defeated the Spanish. www.geni.com/people/Felipe-II-el-Prudente-rey-de-Espa%C3%B1a-y-Portugal/6000000001600060051
