Altocumulus Radiatus

Altocumulus radiatus is defined as clouds arranged in parallel lines that appear to converge at a central point near the horizon. Conversely, they could be said to appear to radiate from a central point, hence the radiatus in the name. Of course they aren’t really converging or radiating. They only appear to be because of perspective. In open country or on the sea, the horizon is a lot farther away than the clouds overhead. Our minds are tricked by their tendency to assume that they are roughly equally distant. That our sky is bowl shaped and the overhead dome is as far away as the horizon. So, even though the lines of altocumulus clouds are parallel and so just as far apart at the horizon as they are directly overhead, we see them as converging and radiating.

Altocumulus radiatus are not indicative of any particular weather. They’re just something that stands out and can be given a name, and we humans do like to do that, don’t we?

Fossil Fuel Subsidies Cost $5 Trillion Annually

They keep telling us that alternatives to fossil energy are too expensive. That we shouldn’t be subsidizing the alternatives because it creates an uneven playing field. They tell us that the alternatives should compete on merit, just like the fossil energy industries do, and stop looking for government handouts. I think we should go the other way and subsidize the competition to the same level we already have been subsidizing the incumbent. With that kind of money, I foresee rapid advancements in new technology. – rjb

Global energy subsidies, including the social and environmental costs associated with heavily subsidized fossil fuels, are costing the world’s governments upward of $5 trillion annually, according to new estimates released yesterday by the International Monetary Fund.
