Climate change is reshaping how heat moves around globe
The Earth’s atmosphere and oceans play important roles in moving heat from one part of the world to another, and new research is illuminating how those patterns are changing in the face of climate change.
The greenhouse effect and carbon dioxide aren’t the only issues to consider as the planet grows warmer – they are just one part of the equation. The way that the atmosphere and oceans move heat around is changing, too, and this could have significant effects on temperatures around the world.
Without heat transfer, the world’s hottest spots would be sizzling and the coolest spots would be even more frigid. Conditions in both hot and cold climates are affected by the movement of heat from the equator toward the poles in the atmosphere and oceans.
The study concludes that warming temperatures are driving increased heat transfer in the atmosphere, which is compensated by a reduced heat transfer in the ocean. Additionally, the excess oceanic heat is trapped in the Southern Ocean around the Antarctic.
For now, that heat is not re-entering the atmosphere, but at some point it may. If that were to happen, changes in heat transfer could contribute to significant shifts in normal temperatures worldwide. For instance, if we didn’t have heat transfer, Ohio would be 20 or 30 degrees colder than we are right now.
