The US Department of Energy has pulled out of a flagship project to build the first 'clean' coal-fired power plant in the United States, a move that will kill the project unless supporters can rouse Congress on its behalf.

The consequences of global climate change are profound, and the scientific community has an obligation to assess the ramifications of policy options for reducing greenhouse gas emissions and enhancing CO2 sinks in reservoirs other than the atmosphere. Ocean iron fertilization (OIF), one of several ocean methods proposed for mitigating rising atmospheric CO2, involves stimulating net phytoplankton growth by releasing iron to certain parts of the surface ocean.

One way to cut greenhouse gas levels in the atmosphere may be to exploit a particular talent some plants have of locking away carbon. All we need to do is choose the right strains of crops to grow, and they will sequester carbon for us for millennia. That's the idea of two agricultural scientists in Australia, who say the trick is to grow grasses such as wheat and sorghum, which lock up large amounts of carbon in so-called plantstones, also known as phytoliths.

Climate change and policies to address it will fundamentally alter the market dynamics of the forest products industry. The management of forests and the manufacturing, use, disposal, and recycling of forest products can affect the balance of greenhouse gases in the atmosphere. Because trees are a renewable resource with an ability to capture and store carbon, forest products companies that invest in sustainable production practices may be well positioned to provide climate change solutions through new and existing business models.

This report aims to evaluate CCS in the context of climate stabilization wedges and the challenges and opportunities linked to its wide scale deployment. This report first examines the technologies that comprise CCS, exploring the state of development of each component technology and how mature the technology is, as well as who the early adopters in the market place are.

This book shows how various levels of society can work towards climate neutrality. Written and reviewed by experts from many disciplines and various countries, the book is aimed at a broad audience, with solutions for individuals, small and large businesses, NGOs, international organizations, cities and countries.

Environmental groups have condemned an Australian company's plan to dump tonnes of urea into Philippine waters as part of an experiment called ocean fertilization to combat climate change. The

This paper focuses on the following areas: reducing methane emissions from ruminant animals (cattle, sheep) by modification of plant composition; reducing nitrous oxide emissions by making the use of nitrogen more efficient both in terms of going from soil to plant and in the animal; plant breeding may also enhance carbon sequestration in grasslands by focusing both on below ground traits of importance and on the composition of material returned to the soil as litter; and the processes involved in fertiliser production, particularly nitrogen fertilisers, result in considerable greenhouse gas

For drylands with low inherent levels of biological productivity, coping with climate change presents particular problems. The world’s drylands cover over 40 % of the global terrestrial area and house more than 2 billion inhabitants MEA, (2005). The world’s poorest people live in these areas and they will be hit hardest by the adverse effects of climate change. The effects will manifest themselves not through increased temperatures per se but rather via changes in hydrological cycles characterised by both increased droughts and paradoxically, increased risks of flooding.

Companies and countries are planning a series of controversial experiments to help determine if seeding the ocean with iron can mitigate global warming.
