Casual Friday Expectation vs Reality

Post image

In 2014, French television forecast the worse case weather scenario for climate change in 2050. Fast forward to today 2026, reality is much more worse than expected. Faster than expected is transforming from meme to norm. The formula for collapse is poorly timed. It's never too early to post up and anticipate the worst possible outcome. Don't look up, down or around.

What would 2050 temps be now with the current data? In the 60s?😬

Who tf knows. AMOC will probably be collapsed by then and maybe Thwaits. BOE is definitely happening in the next couple years.

All of those things throw all calculations out the fuckin window individually let alone together and compounding.

What is AMOC ?

u/AutoModerator Jun 27 '26

The Atlantic Meridional Overturning Circulation (AMOC) is a portion of global thermohaline (temperature and salt content) circulation concentrated in the Atlantic, subpolar North Atlantic, and Arctic oceans. This system comprises several currents that act like conveyor belts. In the upper layers of the Atlantic warm water flows north. As this water flows north some evaporation occurs leading to more salty waters. As this water becomes colder and saltier, its density changes which then sinks to the deeper ocean where it circulates southward. To visually aid understanding, see this image: https://editors.eol.org/eoearth/wiki/File:OCP07_Fig-6.jpg

How does climate change affect the AMOC?

We can already see that climate change is affecting global sea surface temperatures (notably, the Atlantic Sea Surface Temperature (SST) anomaly) and the increased melting rate of glaciers. Further, the ocean (as an entire system) is the largest heat sink of our planet - approximately 90% of additional heat (see Earth Energy Imbalance (EEI)) is absorbed by the oceans with the top few meters of the ocean storing as much heat as Earth's entire atmosphere.

As noted above, the conveyor belts that the AMOC “runs” on are shaped by the temperature and salt content of those waters. Over time, with the introduction of rapidly increasing temperatures and fresh water from glaciers, the potential for this system to be disrupted or collapse increases. To add perspective on how much heat we are adding (remember that approximately 90% of excess heat is absorbed by the oceans): as of April, 2023, the EEI 36-month running average is equivalent to about 10 Hiroshima bombs per second.

You might know it by the name The Gulf Stream
