Effects on ocean among primary climate concerns for Iceland

Ocean acidification, increased frequency of landslides, and possible changes to ocean currents are some of the impacts of climate change that could most affect Iceland, according to the country’s experts. Responding to the newly released report from the UN’s Intergovernmental Panel on Climate Change (IPCC), Iceland’s Environment Minister Guðmundur Ingi Guðbrandsson says government around the world need to step up their response to the climate crisis.

The PICC’s newest climate change report, intended as a resource for policymakers, compiles the latest data on climate change. Compared to the panel’s earlier reports, its findings are categorical about climate change being caused by humans and about the severity of the consequences it has in store.

Ocean acidification as concerning as warming

Tómas Jóhannesson is Director of Glaciology and an expert on the avalanche team at the Icelandic Met Office. He says the impact on the ocean surrounding Iceland is one of the biggest concerns regarding the local impact of climate change. The earth’s ocean’s have absorbed around 90% of the heat that has accumulated due to the increased greenhouse effect.

Considering Iceland’s dependence on the ocean, its acidification as a result of the carbon it absorbs from the atmosphere could be a long-term issue for the country. Acidification can affect the survival of smaller ocean organisms, in turn affecting the survival of fish and sea birds. “The acidification of the sea is unequivocal and is just as much a reason to stop emissions as warming,” Tómas stated.
