The Mysterious Cold Blob and the Threat to Earth's Climate

TLDROceans absorb 90% of the heat trapped by greenhouse gas emissions, but recent records show that the ocean itself is experiencing heat waves. One exception to this warming is a cold blob in the North Atlantic, which has actually cooled since the Industrial Revolution. This phenomenon, along with the weakening of the Atlantic Meridional Overturning Circulation (AMOC), could be a sign of a collapsing earth system with severe consequences. Scientists are concerned about the potential impacts, including cooling temperatures, extreme weather, changes in rainfall patterns, rising sea levels, and disruption of marine ecosystems. The risk of collapse may be greater and closer than previously thought.

Key insights

🌊Oceans absorb 90% of heat trapped by greenhouse gas emissions

🔥Heat waves are occurring in the ocean due to global warming

🌡️The North Atlantic has a cold blob that has cooled since the Industrial Revolution

🌍The weakening of the AMOC could have severe consequences worldwide

🌡️The AMOC is currently flowing at its slowest rate in over 1,000 years

Q&A

What causes the cold blob in the North Atlantic?

The cold blob in the North Atlantic is likely caused by the melting of Greenland's ice sheet and increased precipitation in the far north, which dilutes the water and reduces its density.

What are the potential consequences of the AMOC collapsing?

The potential consequences of the AMOC collapsing include cooling temperatures, more extreme weather events, changes in rainfall patterns, rising sea levels, disruption of marine ecosystems, and impacts on food production.

Can we prevent the collapse of the AMOC?

While it is difficult to predict and prevent the collapse of the AMOC, reducing greenhouse gas emissions and taking action to mitigate climate change can help to minimize the risks.

How soon could the collapse of the AMOC occur?

Recent studies suggest that the collapse of the AMOC could occur around mid-century under the current scenario of future emissions.

What can individuals do to address this issue?

Individuals can contribute to addressing this issue by reducing their carbon footprint, supporting sustainable practices, and advocating for climate action.
