This week the most important thig I have learnt is how the ice flow to the ocean and as our planet warms, sea levels are set to rise.
Most of us do not live in polar regions. We do not come in contact with icebergs or ice sheets very often. Most of us have only seen these things in photographs. However, no matter where you live, the snow and ice of the Earth’s cryosphere has an impact on your climate.
So, this week makes me wonder how big could be the impact of the sea level in the coastal communities in Galicia ( the region of Spain where I live).
I have found a study realized by environmental education program Voz Natura 2007, using as source information obtained from the Institute of Geology of Coruña and the report Glaciers Dominate eustatic sea-level rise in the 21st Century, published by the journal Science.
In this study you can see the effect of sea level rise on the Galician coast, since 2007 to beyond 22,000. However, the first consequences are observed before 3000, with the disappearance of some populations.

And what about sea acidification?
If the carbon dioxide levels increase, the pH of the ocean will descend. So the ocean becomes more acidic. This fact can seriously affect to calcifying species because their shells can dissolve.
Again I tried to search some information about how the acidification of the ocean have influence in Galicia.
We agree that swim in acid is not a good idea, and less live in that environment so, the first consequences begin to emerge. Red tides increase in duration and intensity, mussel farming sufers a drop of 20% growth. Sardine fisheries have suffered reductions and the sardines are already migratin north and the same process explain the reduction in catches of octopus. Also, shellfishing is possibly the most sensitive to climate change.
The sea acidification can have a terrible effect on fishing and shellfish farming in Galicia.
In conclusion, all this data concerning Galicia could be applied in other parts of the world because climate change is a global issue with impacts all over the world and the sea level rise and acidification affects in one way or another.
