World-wide observations of current climate change, such as increased temperature and severe rain events and droughts are caused by release of CO2 by human activities using fossil fuels and by biogeochemical feed-back mechanisms (Solomon et al. 2007, Wesssel et al. 2004, Melillo et al. 2011). Such changes may disrupt the functioning of terrestrial ecosystems on our planet, which are vulnerable to disturbance (Millennium Ecosystem Assessment 2005, Elmendorf 2012).
