 The Atlantic meridional overturning circulation, AMOC, is a key component of the Earth's climate system, and its collapse could lead to drastic changes in the climate of the North Atlantic region. Recent studies have suggested that the AMOC may be weakening due to rising levels of atmospheric carbon dioxide, but these predictions are not yet conclusive. Researchers have identified two potential warning signs of a possible collapse and increase in variance and autocorrelation, which have been observed in recent years. Based on this evidence, they estimate that the AMOC will likely collapse sometime between now and mid-century if current emission trends continue.
