Colorado State University forecasters predicted the Atlantic hurricane season that began on Wednesday would be a busy one with 16 tropical storms and nine of those growing into hurricanes. They said there was a 47 percent chance that a major hurricane would make landfall along the U.S. coast of the Gulf of Mexico, where major oil and gas facilities are clustered. The CSU outlook is in line with those of other meteorologists who issue seasonal forecasts, all of whom expect an above-average year.

Brazil's environment agency gave its definitive approval on Wednesday for construction of the Belo Monte hydroelectric dam. This is a much debated project in the Amazon that has drawn criticism from native Indians and conservationists. The 6-km-long (3.75-mile) dam, to be the third largest in the world with a cost of $17billion, might displace 30,000 river dwellers, partially dry up a 100-km (62-mile) stretch of the Xingu river, and flood large areas of forest and grass land. The government has said that the 11,200-megawatt project, to start producing electricity from 2015, is crucial for the Brazil's fast-growing economy.

Logging mostly illegal continues in Congo, despite a moratorium on new forestry contracts in place since 2002. Rich countries have pledged billions of dollars under the scheme for Reducing Emissions from Deforestation and Forest Degradation (REDD), which effectively pays developing countries not to cut their forests down. But developing countries complain that, apart from a deal with Norway and Indonesia worth $1 billion to halt licenses for clearing Borneo's forests, funds have been slow to trickle out.

Environmental experts from 35 countries have gathered in the Congo Republic, DRC's smaller neighbor, on Tuesday for a week-long summit seeking ways to protect the world's three largest rainforests -- the Amazon in South America, the Congo in Central Africa and the Borneo-Mekong in Indonesia. The outcome of the summit could play a role in the preservation of some 80 percent of the world's remaining tropical forest, seen by experts as key to offsetting rising global emissions of heat-trapping carbon dioxide - reports Thomson Reuters.

In a recent news article in Nature, the author Fred Pearce examined the assumption behind the latest estimate of the population growth. The global  population expected to rise one more billion by the end of the century.
