Newest investigation of relationship between past warming and sea-level rise confirms that sea-level rise is imminent even in case of stabilization at today’s CO2 levels. Moreover, new conclusion is that rise level will be much higher than it was predicted by long-term projections from the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). Corresponding research was accomplished by team from the National Oceanography Centre, Southampton (NOCS), along with colleagues from Tübingen (Germany) and Bristol. We take notice that GLOBIO3 global terrestrial biodiversity model currently not includes any effect of sea-level rise. This effect, however, can cause dramatic boost of biodiversity loss process via changes in land surface, unexpected mass migration over the Earth and impact on global economy in nearest future. The GLOBIO(EEBIO) East Europe team chalk up the summary and suggests to include the sea-level rise effect to model across with expected revised IPCC projections. Currently the GLOBIO(EEBIO) East Europe team work on model improvements for providing with more precious assessment of the climate change effect on biodiversity using SDM’s (Species distribution models).
