Many countries in Africa are starting to turn the corner economically.

A new report presented at the European Respiratory Society's Annual Congress in Amsterdam over the weekend claims that individuals who regularly bicycle in major cities like London and Amsterdam ha

Turn greenhouse gases to stone? Transform them into a treacle-like liquid deep under the seabed? The ideas may sound like far-fetched schemes from an alchemist's notebook but scientists are pursuing them as many countries prepare to bury captured greenhouse gases in coming years as part of the fight against global warming. Analysts say the search for a suitable technology could become a $150 billion-plus market. But a big worry is that gases may leak from badly chosen underground sites, perhaps jolted open by an earthquake.

Recipe for energy saving unravelled in migratory birds

Texas oilman T. Boone Pickens has placed an the largest ever order for wind turbines: he ordered 667 wind turbines from GE, each costing $3 million dollars, making the total order $2 billion. Picken plans to develop the world's largest wind farm in the panhandle of Texas.

Large-scale destruction of mangroves contributed heavily to the damage inflicted by cyclone Nargis in Myanmar last week, says the UN Food and Agriculture Organization (FAO). Myanmar, home to the eighth largest mangrove area in the world, has lost large swathes of mangroves over the last four decades. FAO estimates from 2005 put the loss at around 70,000 hectares between 1972 and 2005, but 2008 estimates suggest this could be much higher.

A new NASA-led study shows human-caused climate change has made an impact on a wide range of Earth's natural systems, including permafrost thawing, plants blooming earlier across Europe, and lakes declining in productivity in Africa.

Some day, fuel cells may power your car and exhaust only water and perhaps carbon dioxide. More efficient and cleaner than an internal combustion engine, their emissions will be much lower. They may also run your home without the energy loss of power lines, or even power your laptop or cell phone. But not today or even tomorrow.

The ongoing food crises in 36 countries around the globe are a cause of worry for major institutions such as the World Bank because the problems signal profound problems of disbalance in the world economy. The main reasons behind the high food prices in poor countries are the high oil price and market liberalization shocks. Biofuel crops are hardly a factor. Climate change is something that has played a role for as long as everyone can remember and it's only being recognized now.

Some of the world's largest biotechnology companies have filed hundreds of patents on "climate ready" gene-altered crops, hoping to dominate a market expected to emerge as farmers respond to environmental stresses caused by global warming, an advocacy group for subsistence farmers said in a report today. BASF, Monsanto, Bayer, Syngenta, Dupont and biotech partners have filed 532 patent documents around the world for crops genetically altered to adapt to rising temperatures, the ETC Group's report says.
