Excerpt: The first sunspot appeared in January this year and lasted only two days. A tiny spot appeared last Monday but vanished within 24 hours. Another little spot appeared this Monday. Pray that there will be many more, and soon. The reason this matters is that there is a close correlation between variations in the sunspot cycle and Earth’s climate. The previous time a cycle was delayed like this was in the Dalton Minimum, an especially cold period that lasted several decades from 1790. Northern winters became ferocious: in particular, the rout of Napoleon’s Grand Army during the retreat from Moscow in 1812 was at least partly due to the lack of sunspots. That the rapid temperature decline in 2007 coincided with the failure of cycle No.24 to begin on schedule is not proof of a causal connection but it is cause for concern. It is time to put aside the global warming dogma, at least to begin contingency planning about what to do if we are moving into another little ice age, similar to the one that lasted from 1100 to 1850. There is no doubt that the next little ice age would be much worse than the previous one and much more harmful than anything warming may do. There are many more people now and we have become dependent on a few temperate agricultural areas, especially in the US and Canada. Global warming would increase agricultural output, but global cooling will decrease it. Millions will starve if we do nothing to prepare for it (such as planning changes in agriculture to compensate), and millions more will die from cold-related diseases. […] All those urging action to curb global warming need to take off the blinkers and give some thought to what we should do if we are facing global cooling instead. It will be difficult for people to face the truth when their reputations, careers, government grants or hopes for social change depend on global warming, but the fate of civilisation may be at stake.

The Australian: Sorry to ruin the fun, but an ice age cometh

The Antarctic deep sea gets colder, which might stimulate the circulation of the oceanic water masses. This is the first result of the Polarstern expedition of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association that has just ended in Punta Arenas/Chile. At the same time satellite images from the Antarctic summer have shown the largest sea-ice extent on record. In the coming years autonomous measuring buoys will be used to find out whether the cold Antarctic summer induces a new trend or was only a “slip”.

The Polarstern expedition ANT-XXIV/3 was dedicated to examining the oceanic circulation and the oceanic cycles of materials that depend on it. Core themes were the projects CASO (Climate of Antarctica and the Southern Ocean) and GEOTRACES, two of the main projects in the Antarctic in the International Polar Year 2007/08.

Under the direction of Dr Eberhard Fahrbach, Oceanographer at the Alfred Wegener Institute, 58 scientists from ten countries were on board the research vessel Polarstern in the Southern Ocean from 6 February until 16 April, 2008. They studied ocean currents as well as the distribution of temperature, salt content and trace substances in Antarctic sea water. “We want to investigate the role of the Southern Ocean for past, present and future climate,” chief scientist Fahrbach said. The sinking water masses in the Southern Ocean are part of the overturning in this region and thus play a major role in global climate. “While the last Arctic summer was the warmest on record, we had a cold summer with a sea-ice maximum in the Antarctic. The expedition shall form the basis for understanding the opposing developments in the Arctic and in the Antarctic,” Fahrbach said.

In the frame of the GEOTRACES project the scientists found the smallest iron concentrations ever measured in the ocean. As iron is an essential trace element for algal growth, and algae assimilate CO2 from the air, the concentration of iron is an important parameter against the background of the discussion to what extent the oceans may act as a carbon sink.

As the oceanic changes only become visible after several years and also differ spatially, the data achieved during the Polarstern expeditions are not sufficient to discern long-term developments. The data gap can only be closed with the aid of autonomous observing systems, moored at the seafloor or drifting freely, that provide oceanic data for several years. “As a contribution to the Southern Ocean Observation System we deployed, in international cooperation, 18 moored observing stations, and we recovered 20. With a total of 65 floating systems that can also collect data under the sea ice and are active for up to five years we constructed a unique and extensive measuring network,” Fahrbach said.

In order to get the public, and especially the young generation, interested in science and research and to sensitise them for environmental processes, two teachers were on board Polarstern. Both took an active part in research work and communicated their experiences to pupils, colleagues and the media via internet and telephone. “We will bring home many impressions from this expedition, and we will be able to provide a lively picture of the polar regions and their impact on the whole earth to the pupils,” Charlotte Lohse, teacher at the Heisenberg-Gymnasium in Hamburg, and Stefan Theisen from the Free Waldorf School in Kiel said.

AWI Press Release: The Antarctic deep sea gets colder

Long before we are extinguished by global food shortages or raised sea levels, I predict, we are fated to die of boredom, struck down in our prime by the devastating virus 0157eco-smugness. Doctors will be powerless to stop as the bug invades our minds, causing nervous paralysis leading to eventual seizure. We are doomed, for sure, to terminal ennui brought on by environmental righteousness.

This is the terrible paradox of the environmental movement. The paradox that, if society proceeds down the true path of eco-purity, we may well save the planet; but will simultaneously discover that life is too dull to be worth living on it any more. Women in particular, I fear, will find themselves returned to the Dark Ages.

How can it be otherwise? No skiing, no cars, no travel, no exotic foods, no extravagance, no Hollywood, no wasteful labour-saving devices, no clothes made of anything but recycled plastics and hemp. No more Luxx magazine filled with beautifully engineered, sleek, accessory porn. In their place we will chant a litany of carbon offset, recycling and composting, the buttresses of a new religion that makes radical Islam resemble Methodism.
