What is geoscience?

Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...

Clickbait. Ocean currents, and the means by which they redistribute heat, have been both a known mechanism, and considered a significant factor, for a while.

We just don't know how significant it will be in the context of the PPM and temperature ranges we're looking at this century (e.g. what will trigger tipping points and feedback loops).

Click bait much? Kinda interesting.

Their findings revealed that the movement of Earth’s continents during the Cretaceous period caused a slowdown in the large swirling ocean currents responsible for carrying warm water from the equator to the poles. This slowdown disrupted the way the ocean regulated its surface temperatures, resulting in a significant increase in temperature differences between the poles and the tropics during that time. These findings align with geological evidence from the Cretaceous era, providing a more comprehensive understanding of past climate dynamics.
