"If this ice melts in Greenland it can shut down the Gulf Current"

This quote by Jay Inslee is referring to the potential effects of international warming. If the ice in Greenland melts due to rising temperatures, it might have a devastating impact on the Gulf Stream, an effective ocean present that brings warm water from the Gulf of Mexico up the east coast of North America. This present assists to keep the climate in Europe and North America milder than it would otherwise be. If the Gulf Stream were to close down, temperature levels in Europe and North America would drop considerably, resulting in extreme climate condition and an interruption of the international climate. This might have a disastrous effect on the environment, wildlife, and human populations. It is for that reason essential that we take action to reduce global warming and prevent the ice in Greenland from melting.
