Irrigating Africa as the rains become unreliable
You might not think irrigation would be a good way to boost production on sub-Saharan Africa's chronically underperforming farms. After all, many parts of the region, particularly the south, are expected to see drying weather and worsening droughts as clim
A painful look back at Copenhagen
The International Institute for Environment and Development is promoting a documentary that it says "provides a revealing insight into the way international diplomacy can become an intricate game" that potentially threatens millions of the world's poorest
Fast-start funding shaping up, but using it effectively will take work - study
At Copenhagen, wealthy nations promised developing countries $30 billion in 'fast start' assistance from 2010 to 2012 to help them adapt to the effects of climate change and try to minimize their own emissions of greenhouse gases. Is the money coming? A ne
Cut fossil fuel subsidies to save emissions and budgets, OECD urges
It sounds like a win-win proposition: phasing out fossil fuel subsidies worldwide could cut greenhouse gas emissions by 10 percent, and save cash-strapped governments a load of money in tight financial times, the Organisation for Economic Co-operation and
Rare temperature records show long-term warming trend
Getting evidence of long-term temperature changes is hard work. Weather stations change location over the decades, and readings from once-rural recording stations are affected by the shade-throwing buildings or heat-trapping tarmac roads built around them.
Could global warming trigger geological disasters?
Could climate change be triggering more geological activity? In an article this week in the Guardian, British scientists say changes in glacier melt, snowfall and storms might redistribute enough weight on the earth's surface to potentially trigger geologi
Grassroots climate adaptation efforts paying off
Building climate change adaptations that works will require focusing on community-based ideas, then starting small and scaling up what works. That's been the thinking for some time, but early results from a community adaptation push backed by the U.N. Deve
Detailed reporting aims to improve data, boost faith in climate science
Public opinion polls show a growing number of people question the science behind climate change. A recent stolen email scandal, a handful of errors in key UN reports and some uncharacteristically brutal winter weather in northern climes haven't exactly rea
Shortfall in promised emissions cuts needs quick remedy, Steiner says
To have a fighting chance at keeping global temperature increases below 2 degrees Centigrade - the most widely agreed 'safe' level of climate change - countries will have to stump up significantly deeper emissions cuts than they've promised under the recen
VIDEO: Hurricane-hit Grenada braces for expected climate impacts
The Caribbean island of Grenada, like other small island developing states, is facing daunting challenges as a result of climate change. This short video looks at hurricane damage on the island and the nation's efforts to prepare itself for coming problems
