What is the current outlook for Argentinas coasts?
JORGE CODIGNOTTO: The Argentine coast is affected by a broad phenomenon of erosion, which has been increasing since the 1970s. This has normally been attributed to global warming, because as the planet heats up – the causes of which are being debated – the anticyclones (areas of slowly rotating high atmospheric pressure) move towards the poles, which means more frequent and more intense storms in more southerly areas that normally don’t have them, so there are more waves, more energy, and stronger currents in coastal areas. But there is also an increase in erosion from human causes. TIERRAMRICA: How does the rising sea level influence erosion? JC: Actually, the sea level rises just three millimetres per year, but the important thing is the domino effect: there are more coastal currents that cause erosion, and it is raining more in some places, and that carries soil towards the sea, which modifies ecosystems. It is estimated that in 2025 there will be one billion more people on the plan
