Effective Adaptation, or Dangerous Contribution to Climate Change?

Expanding Global Cold Chains: Effective Adaptation, or Dangerous Contribution to Climate Change? by Benjamin Ritter and Kevin Karl |January 27, 2023 Keeping food cold as it moves through the supply chain is crucial to fighting food insecurity, preventing food waste, and supporting agricultural livelihoods and economies throughout the developing world. But each step and technology of the cold chain — refrigerators, industrial chillers, and transportation — has significant potential impacts on climate change, from massive energy demands to powerful fluorinated greenhouse gas emissions. Together, these impacts make global fo...

Earth’s average recorded surface temperatures were some 1.2°C warmer than preindustrial times. Nearly 30 countries set individual all-time heat records, and some 850 million people experienced the warmest temperatures of their lives last year. As in 2021, the warming was suppressed by a persistent, multiyear La Niña cooling pattern in the tropical Pacific Ocean, the agencies said. But La Niña is expected to wane this year, setting the stage for even higher temperatures. Meanwhile, the world’s oce...
