The Nitrogen in Europe project adopts a multidisciplinary approach to examining and tackling the main problems of excess nitrogen. It identifies nine main problems associated with excessive nitrogen use: aquatic, coastal and terrestrial eutrophication, acidification, climate change, photochemical smog, urban air quality, particles, and stratospheric ozone depletion. The project has recently drafted a declaration on nitrogen and the food chain which you can read here.

The US based NRDC and the Garrison Institute have jointly published a press release and a fact sheet based on the organisation’s internal analysis of opportunities to reduce annual GHG emissions in the US by 1 billion tonnes below business as usual, through simple and inexpensive personal actions.

Since 1999 atmospheric methane concentrations have leveled off while the world population of ruminants has increased at an accelerated rate. Prior to 1999, world ruminant populations were increasing at the rate of 9.15 million head/year but since 1999 this rate has increased to 16.96 million head/year.

This article in the New Scientist entitled 'Methane controls before risky geoengineering, please' by Prof. Kirk Smith, makes the following points:

Increasing temperatures, changing precipitation, rising sea levels, more intense and frequent extreme weather events and melting glaciers, ice sheets and Arctic sea ice are some of the challenges for Europe already triggered by global climate change, says a report released by the European Environment Agency, the World Health Organisation Regional Office for Europe and the Joint Research Centre of the European Commission.

India's greenhouse gas (GHG) emissions rose by 58 per cent between 1994 and 2007 with the energy sector contributing over half of the emissions, according to a report published by the Indian Government’s Minstry of Environment and Forests.
