After 20 years dominated by inaction on climate change, the world is entering a “third era” when the impacts of climate change are unavoidable, says a London climate expert.

Even if countries instantly reduced carbon emissions to zero, the impacts of emissions already in the atmosphere are “inevitable and unavoidable for the next 20 or so years,” said Saleemul Huq, a climate expert at the London-based International Institute of Environment and Development and former executive director of the Bangladesh Centre for Advanced Studies.

Energy demands in South Asia are growing at rate of over 6.0 per cent a year - a pace that is far in excess of the region's capacity to meet. The fact that a sizeable section of the population does not have access to electricity makes energy security a daunting challenge for the countries of this region.

Pollution in China: Man-made and visible from space

Pollution in China: Man-made and visible from space
Show

 “PM2.5” seems an odd and wonky term for the blogosphere to take up, but that is precisely what has happened in China in recent weeks. It refers to the smallest solid particles in the atmosphere—those less than 2.5 microns across. Such dust can get deep into people’s lungs; far deeper than that rated as PM10. Yet until recently China’s authorities have revealed measurements only for PM10. When people realised this, an online revolt broke out. Such was the public pressure that authorities caved in, and PM2.5 data are now being published for Beijing and a handful of other cities.

 This map is a work in progress. The uses of water, air and land are diverse in New Mexico and will change dramatically with climate change. For caretakers of this sacred trust, the map offers a bird’s eye view of the health of our environment. It documents primarily the energy-related sources of pollution, though in New Mexico other polluting factors are also at work.

India records world-beating green energy growth

 Increase of 52% to $10.3bn in 2011 was based on strong solar performance

India's transformation into a cleantech powerhouse moved up a gear in 2011 when it racked up investments of $10.3bn in the sector, a growth rate of 52 per cent year on year that dwarfed the rest of the world's significant economies.

Solar investments led the growth with a seven-fold increase in funding, from $0.6bn in 2010 to $4.2bn in 2011, just below the $4.6bn invested in wind during the year, according to figures released yesterday by analysts Bloomberg New Energy Finance (BNEF).
