AMOC slowdown hits 1,000-year low in new proxy data

Just saw the latest paleoclimate reconstruction showing Atlantic circulation at its weakest point in a millennium. The proxy data from marine sediments is painting a much clearer picture than our instrumental record alone - and it's tracking almost perfectly with our high-resolution models.

The proxy reconstruction gives us the historical context we desperately need for AMOC policy - when circulation patterns haven't been this weak in 1,000 years, we're clearly in uncharted governance territory. The political challenge is that AMOC collapse unfolds over decades, but electoral cycles demand immediate results, creating a massive mismatch between physical and political timescales.
