Final answer:
The ocean's ability to absorb and transfer heat around the globe, absorb carbon dioxide reducing extreme climate change, and the subsequent effects on marine ecosystems and species distribution provide evidence of the ocean's role in climate change.
Step-by-step explanation:
The oceans play a crucial role in regulating the Earth's climate. One key piece of evidence indicating the ocean's significant impact on climate change is its ability to absorb and transport heat around the world. Oceans store vast amounts of solar energy, especially near the equator, and move this heat via currents across different temperature zones. This not only moderates climate by transferring excess heat from equatorial regions to polar ones but also results in more stable maritime climates with fewer temperature variations. Moreover, the ocean's capacity to absorb carbon dioxide has buffered the planet against even more extreme climate change, although it has also led to increased ocean acidity, which affects marine ecosystems. Furthermore, as the global temperature rises by nearly 1°C, it places stress on organisms and changes species distributions, with marine species moving towards the poles faster than those on land.
