Earlier this week, the UNDP published its annual Human Development Report (HDR). This year, the research focused on one global concern - and the seventh Millennium Development Goal: climate change and environmental sustainability.

Released a week before the United Nations Climate Change Conference in Bali, the report gathers a wide variety of data, which reveals that the global warming trend will not cease unless or until decisions makers take global joint actions.

The report states that these actions must be led by the richest countries, as it is only through examples and setting up partnerships programs with the poorest countries that we can hope to improve the situation in the near future. "Working together with resolve, we can win the battle against climate change. Allowing the window of opportunity to close would represent a moral and political failure without precedent in human history" said Kevin Watkins, the lead author.
