Bill Gates has a message for those worried about climate-related disasters like hurricanes, droughts, flooding, and extreme temperatures: No solution works on its own.
“To stop the planet from getting substantially warmer,” he wrote, “we need breakthroughs in how we make things, grow food, and move people and goods — not just how we power our homes and cars.”
That’s a lofty goal — especially in light of a recent report from the Intergovernmental Panel on Climate Change (IPCC), which found that the effects of climate change could reach catastrophic levels in just two decades.
To get ahead of the problem, Gates said, the world must focus on five “grand challenges” to reducing greenhouse gas emissions, which linked to rising global temperatures. These challenges have also been identified by the Environmental Protection Agency as the main sources of global emissions.
