The Paris Climate Agreement entered into force last week, heralding a major milestone in international action on climate change, and an ambitious target to contain global temperature rise to well below 2°C above pre-industrial levels, in this century. Over 100 countries, which account for nearly 70% of global emissions, have ratified the Agreement, and are now obliged to deliver on their commitments and convert their plans into action. But unless countries act decisively and meaningfully, and increase their ambitions over time, this will not be enough to safeguard food and farming.
