Developing Countries’ Climate Change Adaptation Costs May Double $100 Billion per Year by 2050

Global climate is on track for changes including a greater than 2°C rise in average temperature, and that’s going to result in adaptation costs for developing countries well above the World Bank’s 2°C estimate of $70 billion by 2020 and as much as $100 billion per year by 2050, according to a report produced by ActionAid, Care, GermanWatch and WWF, which in a report introduced at the Bonn Climate Change Conference urge government leaders to adopt a set of policies to scale up and accelerate climate change adaptation and mitigation efforts.

The lopsided story of energy subsidies in the United States

Energy Subsidies: Oil versus Renewables

In a world that must reduce its dependency on fossil fuels, replacing oil subsidies with renewable energy subsidies makes sense. Although this is undeniably difficult, it would produce both environmental and economic benefits. Putting an end to oil subsidies would free public money that could be used to promote clean energy and make renewables more competitive. Although renewable energy is destined to increase it…

Hydrogen will become an integral part of the new energy economy

Unlocking Hydrogen Power with Renewable Energy

Hydrogen is the lightest and most common chemical element in the universe, but it is plagued by concerns about its net energy value (NEV). Depending on the type of energy used to make hydrogen fuel, it can be a remarkably sustainable energy source. To be a viable environmentally sustainable power source, hydrogen fuel must be manufactured using renewable sources of energy like solar. A 2005 Scientific American article…

UNFCCC chief warns that 2 degree target is not enough, especially for the most vulnerable nations and regions of the world

UNFCCC Chief Says Two Degrees is Not Enough

UNFCCC executive secretary Christiana Figueres said yesterday that the generally accepted 2 degree Celsius target for limiting global warming is not enough. “Two degrees is not enough – we should be thinking of 1.5C. If we are not headed to 1.5C we are in big, big trouble,” Figueres said at the International Trading Association’s annual Carbon Expo conference. The statement…

Carbon Emissions: Can the U.S. set and meet targets?

Carbon Emissions Spike to Historic High

The International Energy Agency (IEA) released estimates on Monday showing that CO2 emissions have soared to record highs after a lull in 2009 due to the global recession. 30.6 gigatons of carbon dioxide where emitted into the atmosphere in 2010, mostly from burning fossil fuels, a rise of 1.6 gigatons over 2009 according to estimates from the IEA, and up…

When will you be able to drive this hydrogen fuel cell powered car?

EarthTalk: The Future of Hydrogen Fuel Cell Powered Cars

EarthTalk® is a weekly environmental column made available to our readers from the editors of E/The Environmental Magazine Dear EarthTalk: Not long ago we were reading a lot about hydrogen’s role in a clean energy future, with cars transitioning from gasoline-powered engines to hydrogen-powered fuel cells. Where does hydrogen fit now in the mix with electric cars now coming on…
