Climate change will affect tourism and marine ecosystems

sea ​​level rise due to climate change

The effects of climate change such as rising sea levels, higher water temperatures, wave heights, and the increased frequency and intensity of extreme events will affect tourism and marine ecosystems.

These effects of climate change are already present in the Mediterranean Sea, especially in the part of Valencia. Miguel Rodilla is a biologist from the Polytechnic University of Valencia and has commented that all buildings, promenades and coasts of Valencia will have to change their current appearance to adapt to these effects of climate change.

Leave the beachfront

The first thing is to adapt to rising sea levels. To do this, it is best to adapt over the years and change the structure little by little, so that the financial expenses are not so impactful or direct. Leaving the beachfront is a priority Since the threat is not only that of rising sea levels, but with more water, the storms will destroy everything in their path.

With regard to the increase in sea water temperatures, we have the disappearance of many common species and the appearance of many other invasives from remote places such as tropical waters or the Red Sea.

The Mediterranean it is especially sensitive to the acidification phenomenon driven by climate change, which supposes the increase of the acidity of the water, due to the increase of carbon dioxide in the atmosphere. This also causes an obvious increase in water stratification. It consists in that there is great difficulty in the water to be able to mix, which leads to a problem of nutrient availability.

Increased species mortality and adaptation

For the reasons mentioned above, increases in mortality have been recorded in many species such as gorgonians and other species such as calcareous algae have difficulty surviving (this is because algae need high concentrations of calcium carbonate which is no longer available for an increase in CO2 in the water).

The rise in sea level will modify the beaches and the change in frequency and magnitude of storms it will damage and cause problems in coastal structures. Just a slight increase in this level can greatly affect the coastal aquifer and generate problems of fresh water availability.
