The article discusses Energy issues, which includes green machine that helps tackle climate change is the paper book, a good replacement for electronic books, paper books store carbon and are recyclable.

The article discusses geo-engineering and climate change. Geo-engineering includes ideas of protecting the entire Earth from the effects of climate changing carbon dioxide. One such idea is putting large amounts of iron in the oceans to increase the amounts of phytoplankton which consumer carbon dioxide. A paper by the National Oceanography Centre in Great Britain found that geo-engineers have overestimated the amount of carbon removed by nearly 50 times.

Provides evidence that global warming is caused by man's influence on nature. Reference to a paper by Tim Barnett of the Scripps Institution of Oceanography in La Jolla, California, regarding the impact of human activity on global warming; Report that Barnett focused his climate change research on changes in ocean temperatures.

The article discusses the paper by Christopher Field, a co-chair of a working group of the Intergovernmental Panel on Climate Change, in which he wrote that hunting large herbivores could have contributed to global warming.

The article looks at two pieces of research claiming that planting trees can exacerbate drought and fail to tackle climate change. An international study led by researchers at the University of Newcastle, in Britain, and the Free University of Amsterdam, identifies several myths about the link between forests and water. For example, in arid and semi-arid areas, trees consume far more water than they trap. The government of South Africa has been taking a tough approach to trees. Trees lose water through evaporation at twice the rate of grassland or South Africa's unique fynbos scrubland. In a scheme praised by the hydrologists, the state penalizes forestry companies for preventing this water reaching rivers and underground aquifers. The second piece of research looked at how long the forests of the Amazon basin cling on to carbon. In a paper published in "Nature," a team of scientists found that trees were silently returning the carbon after just five years.

This article, the third of a series on the Copenhagen Consensus project, examines climate change. Global warming looms, in many people's minds, as one of the biggest threats facing the planet. Over the past 20 years researchers have gathered evidence that the burning of fossil fuels is causing temperatures to rise. However, the exact pace of global warming, as well as the size of mankind's contribution to the warming trend, remain uncertain. Aside from these issues is the question of precisely how greenhouse-gas emissions should be abated, assuming that they need to be reduced at all. In a new paper for the Copenhagen Consensus project, William Cline of the Centre for Global Development and the Institute for International Economics examines these topics. Rising temperatures are capable of causing great economic harm--though a lot depends not just on how big future rises prove to be but also on how quickly they happen.
