The U.N. Climate Change Conference in Durban, South Africa, is in full swing now, aiming to reach consensus and agreements on addressing the climate challenge by its close on December 9. While there are high expectations, people also realize that this is not an easy issue to tackle. Uncontrolled, man-made carbon emissions, which climbed to a new record of 30 billion tons worldwide in 2010, are at the core of the climate change dilemma. Curbing this trend is not only a daunting multisectoral task that demands sophisticated technical solutions, but its complexity is intensified by disagreements among countries on the size of the problem and what to do about it.
Climate change should matter to all of us, since changing weather patterns, including more frequent extreme climate events (e.g., the 13 warmest years on record have been in the last 15 years) and natural disasters (e.g. in some regions the number of particularly large hurricanes has increased), negatively impact the lives and well being of ALL people—the raison d’être of development. In this context, climate change should be seen as a critical health challenge that demands increased attention and management. Why?
A landmark 2009 report by The Lancet Commission documented how climate change over the coming decades could have a disastrous effect on health conditions across the world. There are both direct and indirect health threats through changing patterns of disease, water and food insecurity, vulnerable shelter and human settlements, extreme climatic events, and population growth and migration.
