No funds for researching cooling effect of the sun

Popular Mechanics has an article on the slow down in solar activity and the difficulty researchers are having getting funding to understand the cooling effect better. Cooling effect? That doesn't play into the current Climate Change hysteria so - no soup for you.

It's a perfect example of my view that the politicisation of science driven by the left will have a negative impact on those looking for funds to undertake real research.

Every day, scientists hoping to see an increase in solar activity train their instruments at the sun as it crosses the sky. This is no idle academic pursuit: A lull in solar action could potentially drive the planet’s temperature down, or even prompt a mini Ice Age.

For millennia, thermonuclear forces inside the star have followed a regular rhythm, causing its magnetic field to peak and ebb, on average, every 11 years. Space weathermen are watching for telltale increases in sunspots, which would signal the start of a new cycle, predicted to have started last March and expected to peak in 2012. “When the sun’s active, it’s a little bit brighter,” explains Ken Tapping, a solar researcher and project director for Canada’s National Research Council.

So far, Tapping reports no change in the magnetic field strength, as measured by radio telescopes. On the more positive side, last month NASA reported a small, earth-sized sunspot with a magnetic field pointing in the opposite direction from those in the previous cycle; qualities that designate the spot as a signal of a new upturn in activity. At the solar maximum, scientists expect to see between 75 and 150 such sunspots per day.

Tapping oversees the operation of a 60-year-old radio telescope that he calls a “stethoscope for the sun.” Recent magnetic field readings are as low as he’s ever seen, he says, and he’s worked with the instrument for more than 25 years. If the sun remains this quiet for another a year or two, it may indicate the star has entered a downturn that, if history is any precedent, could trigger a planetary cold spell that could bring massive snowfall and severe weather to the Northern Hemisphere.

The last such solar funk corresponded with a period of bitter cold that began around 1650 and lasted, with intermittent spikes of warming, until 1715. While there were competing causes for the climatic shift—including the Black Death’s depopulation of tree-cutting Europeans and, more substantially, increased volcanic activity spewing ash into the atmosphere—the sun’s lethargy likely had something to do with it.

Just how much influence the sun has on global temperatures has been the subject of sometimes acrimonious debate. While an upswing in solar activity may cause a warming trend, it was discounted in the mid-1990s as the sole driver of current climate change. And for anyone hoping that a solar downswing might bail us out of our current dilemma: Solar influence on climate is slight compared to the impact of man-made greenhouse gases, a National Academy of Sciences report concluded in 1995.

The planet’s climate is a messy picture, with all sorts of influences and feedback cycles that need to be taken into account. In order to build more accurate computer models, scientists need to understand both anthropogenic factors and the link between the sun and our planet, Tapping says. To help get at the sun’s influence, he and other researchers connect Earth’s temperature with historic sunspot records of sky watchers from Europe and China, as well as with carbon-14 isotopes­—residue from cosmic rays delivered by the sun’s magnetic field—found in tree rings. To understand our role in climate change,” he says, “we need to understand the natural process.”

A new generation of radio telescopes could lead to a better understanding of the sun’s behavior—of importance to space-faring countries, satellite operators, astronomers and earth scientists alike—but currently await government funding.

In Canada, where radio-telescopic monitoring of the sun has been conducted since the end of World War II, a new instrument, the next-generation solar flux monitor, could measure the sun’s emissions more rapidly. It would also provide details about the sun’s emissions by examining signals at more wavelengths than the current instrument. Canada’s space agency coordinates activity with England and the U.S., sharing data and constructing complementary telescopes. Researchers were hoping the new radio telescope would get the green light as early as last week, but are now saying that budget cuts from other countries may delay or even jeopardize the program.

“Things are all on hold due to the consequences of the huge science funding cuts in the U.S. and the U.K.,” Tapping says. “This is impacting other partner countries because of the possible need to cover financial holes. Nobody is clear yet as to how this will unfold so they are hanging onto their wallets, for the moment.”

The new Canadian telescope is an independent project but has been designed to work closely with a proposed array of 100 telescopes in the United States. Collectively called the Frequency Agile Solar Radiotelescope (FASR), the array will directly measure coronal magnetic field strengths. The system will also show the locations of electrons accelerated by solar flares and will provide images of coronal mass ejections. Assuming, of course, it is funded.

“Given fiscal realities, it has been slow in moving forward,” says Tim Bastian, principal investigator of the FASR team, which represents a consortium of American universities. “However, we recently submitted our preliminary proposal for construction to the National Science Foundation and expect to submit the full proposal in June. If all goes according to plan, the five-year construction project will be funded at the end of this fiscal year.” In which case, the first monitoring systems will be coming online in three years, giving us much-needed insight into the state of our local star.

You are very paranoid about 'climate change' being the root of all evil. You should do some research on at least the science funding cuts in the UK. Astronomy here has been sabotaged, whether it has any remote connection to climate or not, and not for your beloved 'political' reasons but simply through bureaucratic incompetence. Hundreds of jobs will be lost and the UK's scientific standing worldwide has taken a hit that it won't recover from for years, but it has nothing at all, whatsoever, to do with climate change.

More government means more incompetence.

It's something that Nanny State lefties don't quite get.

Yes, often that is true. But I'll say it again - that has nothing at all to do with climate change. I bet if the milk on your cornflakes tasted a bit off in the morning you'd blame the lefty climate change promoting media bias.

There is no question that university leftie whackjobs are driving so many of the funding decisions of grants. And while I'm not much of a believer in international conspiracies, there is no question that this UN-based drive on the global warming hoax has international implications which include nothing so much as an intention to hobble the US economy as well as other non socialist Western economies. Plus a huge transfer of wealth from the rich to the poor.

And then when you combine the emotional catastrophe nature of this issue with world government types, you have a potent brew of socialist lefties who will do anything to make sure that this train stays on the tracks.

Under no circumstances can any science emerge that will derail this train.
