Researchers are sounding a serious alarm tonight: the Atlantic Meridional Overturning Circulation, the vast ocean current system that regulates climate across Europe and North America, may already be locked into collapse. Scientists warn the tipping point could be behind us, not ahead, with consequences for weather patterns, sea levels, and agriculture that would unfold over decades.

The system now underpins agents, retrieval-augmented generation, and contact deduplication. The story is a useful window into what it actually costs, in engineering complexity and infrastructure, to run AI at production scale.
