A report by Climate Spectator raises new questions about BHP Billiton’s $20 billion investment in the US shale gas business, saying Mike Yeager, the Houston-based boss of the world's number one miner's petroleum division, has been on quite a roadshow to explain the company's rationale but failed to adequately address the critical issue of water supply. Analysts are skeptical about the prospects of BHP's foray into shale gas – which the world’s most valuable miner could grow to $60 billion over the next decade – considering its poor track record with acquisitions, its relatively limited experience in the fracking business, environmental concerns and warnings that it is again buying at the top of the cycle.

Until recently, this discussion has mainly been the preserve of conspiracy theorists and backbench German politicians. But now the use of gold to fund a euro zone bailout is coming closer to reality.

Reuters reports the board of Brazil's Vale has approved a $6 billion expansion of its Moatize coal project in Mozambique to lift output to 22 million tonnes per year from the 11 million tonnes it expects to mine initially with first production forecast for the second half of 2014. The country's Tete province is believed to hold one of the world's largest untapped coal reserves that has been compared with Australia's coal-rich Bowen Basin. Mozambique suffered a 15-year long civil war that ended in 1992 and remains one of the poorest countries in the world, but the ex-Portuguese colony 7% economic growth this year is forecast to accelerate thanks to billions in mining and infrastructure spending. The Mozambique metical is also the world's best-performing currency.

Nebraska legislators have voted unanimously to reroute the Keystone XL pipeline away from an ecologically sensitive region and the governor has signed new bills into law. The legislation is to pay for new environmental studies on the exact route the rerouted pipeline will take. The state and the proponent of the project, Canadian company TransCanada Corp. (TSE:TRP), agreed earlier this month to reroute the $7 billion project away from the Ogallala aquifer, a sprawling water table that provides water to cities and for irrigating farms. The new path would involve about 50 kilometres of pipeline. The company had long resisted changing the route, having already spent some $1.4 billion securing right of ways and stockpiling material for the project, which would deliver 700,000 barrels of crude oil a day from the Alberta oilsands to Texas refineries.

The arrival of four tiger cubs in Tadoba – one of the country's oldest national parks – has brought cheers to wildlife lovers. However, rampant coal mining in Chandrapur and its surrounding areas pose a grave threat to tiger conservation and protection reports Hindustan Times.

Tadoba tiger reserve was in the news recently for better big cat conservation and birth of 32 tiger cubs in the area since January 2010. India's tiger population has dwindled from tens of thousands a century ago to a mere 1,411 according to the last census conducted in 2008.
