The relationship between climate change and cities is complex. City-based activities contribute significant amounts of greenhouse gases and, simultaneously, are often more vulnerable to the impacts of climate change. Dhaka is now the world's eighth largest city and a significant proportion of Bangladesh's greenhouse gases are generated there although, relative to total emissions worldwide, the contribution is negligible.

scientists have always been puzzled by hills mysteriously rising from the sea floor in the Arctic Ocean. A paper recently published in the journal Geophysical Research Letters (Vol 34 No 1) offers an

methane emission from livestock in India has been found to be much lower than the estimates of the International Panel for Climate Change (ipcc)

While the climate debate is raging, the climate negotiations themselves are barely moving. Finger pointing seems to be the name of the game, with each negotiating bloc focused on passing the bill for solving the climate crisis onto the others. The process as a whole is in impasse, and it's time to admit it, as it's time to admit that disagreements about fairness and equity are at the centre of the impasse.

This report represents an important contribution to the overall discussion on climate change and a post-2012 climate regime. It provides important insights regarding the history of the climate convention and various negotiating positions. It defines the major barriers for an effective post-2012 agreement and suggests possible action to overcome those barriers.

Study focusing on organic agriculture and mitigation and adaptation to predictable and unpredictable impacts of climate change - looks at the general contribution of agriculture to climate change; discusses the considerable potential of organic agriculture for reducing emissions of greenhouse gases, and its contribution to sequestration of CO2 in the soil; outlines weaknesses of organic agricultur
