The Paris Climate Agreement sets forth a bold goal to reduce greenhouse gas emissions, keep global temperature rise below 2.0 degrees Celsius, and employ best efforts toward no more than 1.5 degrees of warming. It also sets forth a new set of rules to achieve these goals. [Video Below]

Over the past decade, the number of undernourished people around the world has declined by around 167 million, to just under 800 million people. However, this positive trend glosses over a stark reality: Food insecurity is increasing in the world’s mountains. This pattern has been under-recognized by development experts and governments, a dangerous oversight with far-reaching social and environmental repercussions.

In an effort to scale-up climate change mitigation, the largest private sector engagement in the history of the United Nations was drafted to fund clean technology projects in developing countries. Carbon credits were to offset pollution in developed nations and pay for clean energy projects in developing countries. But many developed countries, including the United States, spurned the agreement, preferring to manage greenhouse gas emissions internally and build or retrofit infrastructure in ways that directly benefited their economies. The ambitions of the Kyoto Protocol, which went into effect in 2005, were subsequently stranded and then scrapped.

Global climate trends indicate that our planet will continue warming into the next century, leading to more extreme climate conditions. The Latin America and Caribbean region is vulnerable to some of the most challenging aspects of climate change – sea-level rise, changes in precipitation, glacial melting, spreading of disease, and extreme weather events.
