Abstract

Klima se na Zemlji oduvijek mijenjala, no zbog antropogenog utjecaja klimatske se promjene ubrzavaju, a njihove su posljedice sve izraženije. Zbog velike emisije stakleničkih plinova došlo je do globalnog zatopljenja. U proteklih nekoliko desetljeća zabilježen je sve veći utjecaj klimatskih promjena na dinamiku i ekosustav Jadranskog mora. Opaženo je povećanje temperature, posebno izraženo u površinskom sloju do 20 m dubine. Zbog povećane količine antropogeno nastalih plinova (CO2, dušikovi i sumporni oksidi) te njihovog otapanja u moru došlo je do procesa zakiseljavanja. Ono, zajedno sa povećanjem temperature djeluje na sesilne organizme u moru, a posebno su izloženi koralji kod kojih dolazi do izbjeljivanja. Jadran sve više privlači različite termofilne vrste, poput riba, algi, bakterija i želatinoznih organizama. Dolazi i do promjene areala rasprostranjenosti vrsta unutar samog Jadrana te do promjena u dotoku vode i hranjivih tvari rijekama te posljedično do povećanja saliniteta. Sve se češće i ranije pojavljuju cvjetanja fitoplanktona, došlo je do povećanja razine mora, a mijenja se i cirkulacija vode u samom Jadranu. Brojne su druge posljedice koje će se u narednim godinama povećavati ukoliko se klimatske promjene nastave odvijati istim tempom.

Abstract (english)

The Earth“s climate has always changed, but due to the anthropogenic impact it is changing faster. Global warming is an aspect of climate change and it is caused by increased concentrations of greenhouse gases. Adriatic Sea during the last few decades has been influenced by climate change. It has been observed an increasing of water temperature, especially expressed in the surface layer up to 20 m. Another change is an acidification of water due to the increase of atmospheric carbon, nitrogen and sulfur oxides. This, together with the increase of temperature, has an effect on sessile organisms. Coral reefs are especially vulnerable to climate change and they are affected by bleaching. The increasing seawater temperature facilitated the spreading of thermophilic species such fish, algae, bacteria and gelatinous organisms. There is also the change in the migration patterns of species that are native to the Adriatic Sea. A marked decrease of the freshwater outflow that caused a rise of surface salinity was observed during the last few decades. Phytoplankton blooms have been occurring more and more frequently. The sea level and the circulation of the Adriatic Sea is also changing. There are many other consequences that will be magnified in the coming years if temperatures continue to rise at the same rate.
