Abstract:
Based on the analysis of the data on sea surface temperature and pH recorded in sectors of the Colombian Caribbean and Pacific coast, we identified the long term trends which locally represent the global ocean warming and acidification phenomena. Based on these changes we deduced the potential impacts on the marine ecosystems. A rise of about 0.23ºC/decade in the sea surface temperature for the Caribbean Sea and of 0.18ºC/decade for the Pacific Ocean was evidenced. We also found a reduction of approximately 0,071 units/decade in the pH for the Caribbean Sea, and of 0,090 units/decade for the Pacific Ocean in the sectors under study. The estimation of the change in the sea surface temperature for the end of the 21st century suggests an increase of about 2ºC compared to the temperature observed at the beginning of this century. At the end of the 21st century the pH might be 0,5 units lower under the conditions of the A2 extreme scenario. Based on the review of the evidences published by other authors about the impacts caused on ecosystems by the recent sea temperature increase and the pH reduction, it can be assumed that Colombian ecosystems will be dramatically impacted given that changes in the physical environment are greater than those reported up today, a situation that will worsen with time. © Acad.
