POPSDinosaurs Diversified Over Time, not Suddenly During this epoch of riotous biodiversity, flowering plants, social insects, butterflies, modern groups of lizards, mammals, and possibly birds, too, all emerged. Some experts have suggested that dinosaurs were also part of the show, as so many weird fossils, such as duckbilled hadrosaurs, horned ceratopsians, pachycephalosaurs and other wonders, date from this time. But a new study, published on Wednesday in a British journal Proceedings of the Royal Society B, says that dinosaurs were less than a sideshow in the DNA spectacular. Researchers led by Graeme Lloyd of the University of Bristol, western England, devised a "supertree" of dinosaur evolution, patiently analyzing how more than 450 species -- about 70 percent of the known finds -- developed.

POPSDino diversity earlier than first thought Maybe there is the idea that species including the dinosaurs were trying to deal with conditions brought about by the meteor, so many adaptations arose, but nature loves nothing more than competition, even when times are good.

POPSFuture Climate Change
The average surface temperature of the Earth is likely to increase by 2 to 11.5°F (1.1-6.4°C) by the end of the 21st century, relative to 1980-1990, with a best estimate of 3.2 to 7.2°F (1.8-4.0°C) (see Figure 1). The average rate of warming over each inhabited continent is very likely to be at least twice as large as that experienced during the 20th century. Warming will not be evenly distributed around the globe (see Figure 2): Land areas will warm more than oceans in part due to water's ability to store heat. High latitudes will warm more than low latitudes in part due to positive feedback effects from melting ice (as discussed above). Most of North America; all of Africa, Europe, northern and central Asia; and most of Central and South America are likely to warm more than the global average. Projections suggest that the warming will be close to the global average in south Asia, Australia and New Zealand, and southern South America. The warming will differ by season, with

POPSSupermarkets Throwing Away 2 Million Tons Of Food A Year We visited a dozen stores over several nights last week to check what was being thrown away and discovered hundreds of pounds worth of food dumped. At a Sainsbury’s superstore next to the Dome in Greenwich, South East London – the chain’s flagship “environmentally-friendly” shop with its own wind turbines – staff said it was standard practice to throw away food before its sell-by date. And they’re not even allowed to take it home. One said: “Someone just stands there and throws it into the skip. We wish we could buy it – but we’re not allowed.” Pointing to meat on the “reduced” shelf, he added: “Come midnight, anything that hasn’t been sold will get taken off the shelf... if it’s out of date it will be logged on the computer, put against our losses, then in the skip.” Four-pint bottles of milk with nine days still to run had been thrown out, along with nine cans of cola with a date stamp of April 2009.

POPSAl Gore Inches Toward Solartopia A major root of the Solartopian vision of an Earth totally free of fossil and nuclear fuels dates back to the 1975 “Toward Tomorrow Fair” at the University of Massachusetts in Amherst. Featuring, among others, the work of wind pioneer William Heronemus and efficiency guru Amory Lovins, the gathering joined the vision of a totally green-powered Earth with the rise of the grassroots No Nukes movement.
