The study's lead author, Ian Wilson, explains further, "[The paper] supports the contention that the level of activity on the Sun will significantly diminish sometime in the next decade and remain low for about 20 - 30 years."
According to Wilson, the result is a strong, rapid pulse of global cooling, "On each occasion that the Sun has done this in the past the World’s mean temperature has dropped by ~ 1 - 2 C."
A 2 C drop would be twice as large as all the warming the earth has experienced since the start of the industrial era, and would be significant enough to impact global agriculture output.
Earlier this year, astronomers from around the world noted solar activity was suspiciously low; some began predicting global cooling at that time. Since then, activity has remained far below average, with it now being over two months since a single sunspot has appeared on the surface of the sun.
In May, a team of German climatologists published research stating that, due to "natural effects", global warming would halt for up to 15 years.
The new paper appears in the June issue of PASA, Publications of the Astronomical Society of Australia.

quote: I was about to say IF, but when we start drilling for oil again domestically, It should have several factors you have missed.
quote: I see no downsides for drilling and finding new sources of oil.
quote: Market forces? There will be a desperate rush for action when oil reserves run low along with a huge price tag and all the other negative things- If money is not spent on those alternative projects earlier.
quote: Sure, I see that plenty of you think that it's possible to drill for oil and develop new sources of energy at the same time, but I don't think that's how the world works... Where is the incentive for anyone to invest in nuclear then? If you reduce the price of oil, how can you hope to limit consumption?

quote: All he's doing is showing that there is other research out there that indicates the opposite. Does it mean we should all get into a panic and implement policies to stop global cooling? No.
quote: How many would you expect to finish a research paper, 12? Does the number discount the research?
quote: The key thing to bear in mind is that both my article and Michael's were speculative in nature
quote: If the pole were to melt out, or if there really was to be 1-2 degree cooling, that would be tiered news

quote: Now that I'm here, there are two opposing viewpoints. Don't like that? Only like your own view? Tough. If you want you can only read Michael's articles. Nobody is making you read mine
quote: If GW proponents who read my articles were to criticize Mike's right to write his side of things that would be equally disturbing to me

quote: There are many examples of Masher's articles that were classified as blogs that are reports on past events contain no speculation by Masher. Here's just one: http://www.dailytech.com/Temperature+Monitors+Repo... This is a past event. Anything resembling speculation in that article is a fact driven statement: eg "Cold is more damaging than heat", "the warm periods ... were beneficial for civilization"
quote: But I am still sticking to my main point. One blog was given a link on anandtech, and another was not. Thus anandtech is implicitly endorsing one side. This is called bias.
quote: We provide serious opposing viewpoints on controversial topics like GW, piracy, OS debates, etc., something which most networks only make a half-hearted attempt at
