The University of California has announced that it has sold off more than $200 million worth of investments in coal and tar sands companies. University officials say the move was prompted by concerns over environmental sustainability as well as the increasing riskiness of investing in the coal and tar sands industries, which have both seen their profits plummet in recent months. Bill McKibben, co-founder of 350.org, hailed the move. The European Green Party and 350.org recently launched the “Divest for Paris” challenge, calling on institutions, individuals and governments to divest from fossil fuels ahead of the climate summit in Paris later this year.

Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon dioxide from the atmosphere, converting it to carbohydrates and oxygen. Many phytoplankton species also release dimethyl sulfide (DMS) into the atmosphere, where it forms sulfate aerosols, which can directly reflect sunlight or increase cloud cover and reflectivity, resulting in a cooling effect. The ability of phytoplankton to draw planet-warming carbon dioxide (CO2) from the atmosphere and produce aerosols that promote further cooling has made ocean fertilization — through massive dispersal of iron sulfite and other nutrients that stimulate phytoplankton growth — an attractive geoengineering method to reduce global warming.
This book argues that Africa can feed itself in a generation and help contribute to global food security despite its history of persistent food shortages and the rising threat of climate change. To achieve this, the continent must harness scientific and technological advances, invest in infrastructure, foster higher technical training, and create regional markets. It must also foster a new crop of entrepreneurial leaders dedicated to the continent’s economic improvement.
This new edition provides ideas on how to place agriculture at the center of the continent’s long-term economic transformation. It demonstrates how policy coordination can help realize agriculture’s full potential as a motherboard for other economic activities. Incorporating lessons from academia, government, civil society, and private industry, The New Harvest outlines how African countries can work together at regional levels to generate new knowledge and resources, harness technological advancement, encourage entrepreneurship, increase agricultural output, create markets, and improve overall economic performance.
Welcome to Transition Studies. To prosper for very much longer on the changing Earth humankind will need to move beyond its current fossil-fueled civilization toward one that is sustained on recycled materials and renewable energy. This is not a trivial shift. It will require a major transition in all aspects of our lives.
This weblog explores the transition to a sustainable future on our finite planet. It provides links to current news, key documents from government sources and non-governmental organizations, as well as video documentaries about climate change, environmental ethics and environmental justice concerns.
The links are listed here to be used in whatever manner they may be helpful in public information campaigns, course preparation, teaching, letter-writing, lectures, class presentations, policy discussions, article writing, civic or Congressional hearings and citizen action campaigns, etc. For further information on this blog see: About this weblog. and How to use this weblog.
