For the past decade, the concept of “sustainability” has dominated climate change conversation around the world. Sustainable development, which aims to meet present needs without sacrificing future well-being, has been an appropriate focus toward the threats that climate change and natural resource depletion pose to our society. However, sustainability is not strong enough, or resilient enough, to stand alone. Global climate change is no longer an event to anticipate and plan for; it is a reality that challenges us today. ... Read more about Resilient San Diego and a Platform for Other Cities

“This figure shows carbon dioxide emissions from 1990 to 2011 for different regions of the world. These totals do not include emissions or sinks related to land-use change or forestry. Inclusion of land-use change and forestry would increase the apparent emissions from some regions while decreasing the emissions from others.” – United States Environmental Protection Agency ...

UN special rapporteur on the right to food champions agroecology as sustainable alternative to existing framework

The existing food system has failed and needs urgent reform, according to a UN expert who argues there should be a greater emphasis on local food production and an overhaul of trade policies that have led to overproduction in rich countries while obliging poor countries – which are often dependent on agriculture – to import food. ...

ClimateWire: Tuesday, February 4, 2014

As the climate changes, some parts of the world will become more hospitable to malaria, putting more people at risk, but large uncertainties still loom over the models making these forecasts, according to a new study.

Malaria is one of the most devastating vector-borne diseases in the world, surging at the intersection of temperature, rainfall, land use and human intervention (ClimateWire, Aug. 13, 2013). ...
