Buffering system in the ocean
WebSep 22, 2024 · The ocean acts as a “buffer” that protects our atmosphere from seeing the full effects of climate change. September 22, 2024. Since the 1700s, humans have raised the amount of greenhouse gases in the atmosphere by almost 50%, trapping a huge amount of heat on Earth. But only a tiny fraction of that heat has actually stayed in the air.
