Faltering Current

Can one ocean current change the climate of an entire hemisphere?For decades, scientists have warned that the Atlantic Meridional Overturning Circulation (AMOC)-the vast ocean conveyor that redistributes heat across the Atlantic-may be weakening. Some researchers argue that continued disruption could reshape weather patterns, alter ecosystems, accelerate sea-level rise, and bring unexpected cooling to parts of Europe despite an overall warming planet. Others caution that the evidence remains uncertain and that predictions of an imminent tipping point may overstate current scientific understanding.The Faltering Current examines one of the most important and debated systems in Earth's climate. Separating established science from speculation, the book explores how the ocean conveyor works, why it matters, what observations reveal, and where scientific consensus ends and uncertainty begins.Accessible to general readers while grounded in current climate research, this volume provides a balanced examination of one of the defining environmental questions of our time and invites readers to better understand the complex forces shaping Earth's future.
