Ocean Current in Trouble: What's Happening to the Gulf Stream?

The Gulf Stream, a major ocean current, is in serious trouble. Scientists have found that climate change is causing it to slow down. This current is part of a bigger system called the Atlantic Meridional Overturning Circulation (AMOC). The AMOC acts like a giant conveyor belt, moving warm water from the tropics to the Northern Hemisphere. The problem starts with the Greenland Ice Sheet. As the planet warms, this ice sheet melts. The meltwater flows into the North Atlantic and disrupts the AMOC. This disruption creates a warm spot deep in the ocean, near the equator. Scientists have been studying this warm spot and found that it has been growing for decades. The slowdown of the AMOC could have big consequences. It could cause temperatures in Europe to drop dramatically. This might sound good, but it's not. The cold would be extreme, like winters in Arctic Canada. It could also affect rainfall and make life harder for people. The last time the AMOC collapsed was thousands of years ago, before the last Ice Age. If it happens again, it could be very bad for people and the environment. Scientists are still trying to understand exactly what will happen if the AMOC collapses. Iceland has even declared the potential collapse of the AMOC a national security threat. This shows how serious the situation is. However, there is still a lot we don't know about how this will affect people.
