Will sea-level rise solve our coastal acid sulfate soil issues?
sea-level rise solve coastal acid sulfate soil issues
2012/3/30
Sea level has risen approximately 1.2 mm/year over the last 100 years (Hennessy et al., 2004) and is predicted to rise up to 80 cm by 2100 relative to 1990 sea levels (IPCC, 2007). The number of extre...
