中美科学家联合调查：关键洋流面临崩溃，恐将开启冰河时代

Core Viewpoint - The research indicates that the Atlantic Meridional Overturning Circulation (AMOC) is at risk of collapse within decades, potentially leading to a new ice age and significant sea level rise [2][4]. Group 1: AMOC and Climate Impact - The AMOC is a crucial ocean current that transports warm water from the tropics to the North Atlantic, influencing the climate of Europe, the UK, and the US East Coast [2]. - The current slowdown of AMOC has been ongoing for decades, with a complete collapse possible by the end of this century [2][5]. - Historical precedents exist, as a similar AMOC collapse occurred approximately 12,000 years ago, marking the end of the last ice age [5]. Group 2: Regional Responses and Concerns - Iceland's climate minister has raised alarms about the potential collapse of AMOC, highlighting it as a direct threat to national stability and security [6]. - This issue has been formally recognized by Iceland's National Security Council, prompting heightened vigilance and coordinated responses from relevant departments [6]. - The international scientific community is increasingly concerned that the risks associated with AMOC collapse may be underestimated, as evidenced by a recent seminar involving 60 experts assessing its societal impacts [6][7].
