Ireland and Britain could become like northern Norway if global warming causes a major change in an Atlantic Ocean current, climate scientists have warned.

As Reuters reports, more than 40 climate scientists have urged Nordic ministers to take action to cut global greenhouse gas emissions due to the risk of a collapse of the Atlantic Meridional Overturning Circulation (AMOC).

AMOC is a system of ocean currents carrying warm water into the north Atlantic and providing Europe with its mild climate.

A collapse of that system could trigger abrupt shifts in weather patterns and damage ecosystems, with severe consequences for people living in the Arctic region and beyond, the scientists warn.

The  Nordic Council of Ministers involves five countries, including Denmark and Sweden, and three autonomous territories.

Marine Science Perhaps it is the work of the Irish research vessel RV Celtic Explorer out in the Atlantic Ocean that best highlights the essential nature of marine research, development and sustainable management, through which Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. From Wavebob Ocean energy technology to aquaculture to weather buoys and oil exploration these pages document the work of Irish marine science and how Irish scientists have secured prominent roles in many European and international marine science bodies.

 

At A Glance – Ocean Facts

  • 71% of the earth’s surface is covered by the ocean
  • The ocean is responsible for the water cycle, which affects our weather
  • The ocean absorbs 30% of the carbon dioxide added to the atmosphere by human activity
