Climate impacts in northern forests
Northern forests hold around 54% of the world’s total terrestrial carbon stock and contribute more than one-third to our global terrestrial carbon sink. This report reviews the impact of human induced

Farming contributes more to global warming than all the world's cars, trains, ships and planes put together. And the single biggest problem with farming is not carbon but nitrogen. From the maize fields of Kansas to the emerald rice paddies of China, today's bountiful harvests depend on generous applications of nitrogen fertiliser. Although only a tiny proportion escapes into the atmosphere as nitrous oxide, it is an extremely potent greenhouse gas. It's a vexing problem, but Eric Rey believes he has some of the answers, in the form of crops genetically modified to require less fertiliser.
More than a decade after the first commercial plantings of genetically modified crops, the same old disagreement rumbles on. On one side stand agribiotech companies, arguing that crops engineered to produce insecticidal proteins or resist herbicides boost yields in an environmentally friendly way. Opposing them are advocacy groups who charge that these crops, or the farming practices they encourage, threaten biodiversity. (Editorial)
Market mechanisms are increasingly being considered as a tool for allocating somewhat scarce but unpriced rights and resources, such as air and water. Tradable permits have emerged as the most cost--effective measure leading to the emergence of both nationwide (SO2) and supranational (CO2) emission permits markets. By means of the dynamic optimization of companies which are covered by such environmental regulations, it develop an endogenous model for the emission permit spot price dynamics that account also for the presence of asymmetric information.
Biotechnology proponents claim that genetically modified (GM) crops are good for consumers, farmers and the environment, and that they are growing in popularity around the world.
This report analyzes the corporate governance and strategic approaches of 40 of the world’s largest banks to the challenges and opportunities posed by climate change. This report is designed as a benchmarking tool that highlights climate change best practices within the financial sector. It employs a “Climate Change Governance Checklist” to evaluate the 40 selected banks in their approaches to climate change in five governance areas: board oversight; management execution; public disclosure; GHG emissions accounting; and strategic planning.
This report provides an overview of information on the world fertilizer situation in 2007/08 and a forecast till 2011/12. The fertilizer situation is examined in relation to crop production and factors likely to affect the latter. High commodity prices experienced over recent years led to increased production and correspondingly greater fertilizer consumption as reflected in tight markets and higher fertilizer prices at the start of the outlook period. While demand for basic food crops, for high value crops such as fruit and vegetables, for animal products and for crops capable of being used to produce bio-fuels is likely to remain strong, it is expected that increased fertilizer consumption required to support higher levels of production will be adequately catered for by growing supply world wide during the outlook period.
This global screening study makes a first estimate of the exposure of the world's large port cities to coastal flooding due to storm surge and damage due to high winds. This study also investigates how climate change is likely to impact each port city's exposure to coastal flooding by the 2070s, alongside subsidence and population growth and urbanisation. The assessment provides a much more comprehensive analysis than earlier studies, focussing on the 136 port cities around the world that have more than one million inhabitants.
Climate change will affect water availability differently in Europe
Biotechnology proponents claim that genetically modified (GM) crops are good for consumers, farmers and the environment, and that they are growing in popularity around the world. Unfortunately, journalists often report such claims as fact, without first subjecting them to critical scrutiny.
The Encyclopedia of Global Warming and Climate Change includes more than 750 articles that explore major topics related to global warming and climate change-ranging geographically from the North Pole to the South Pole, and thematically from social effects to scientific causes. It contains a 4-color, 16-page insert that is a comprehensive introduction to the complexities of global warming.
