Polynesia is a part of the world where tourism, especially focused on rich coral reefs, is an important part of the economy. But from the viewpoint of both tourism and conservation biology, it is one of the most threatened areas of the world. Here the ethical issues are somewhat different. How long can this dependence continue and at what cost? What is the ethical planning course for the Region?s national governments, not just in Polynesia, but throughout the Pacific? Like the general activities on the islands, tourism is heavily dependent on petroleum, both for bringing tourists and supplies and for maintaining them. Thus, the very industry that contributes so importantly to Polynesia?s economic viability also contributes significantly to human-induced global warming. As a region, Polynesia is particularly threatened by the accelerating impacts of global warming. Virtually all the islands are threatened by sea level rise, the atolls by inundation, and the high islands by flooding of infrastructure that is concentrated in low coastal areas. There are also the risks of increased and more intense tropical storms, as well as the risks to ocean ecosystems from rising temperatures and the increased acidification of ocean waters.

The use of socio-ecological controversies, such as global warming, in classrooms has been suggested to increase students’ awareness about complex issues, although detailed analysis of their implementation in classrooms are still scarce. This research shows a model-based inquiry approach (MBI) instructional sequence, using scientific news as a trigger, aimed at addressing a global problem on a real socio-ecological system: the effect of global warming on the Great Barrier Reef. Its implementation in a lower secondary school classroom allowed the assessment of the effectiveness of the instructional sequence designed, based on students’ perception of what secondary school students have learned and felt. Results show that the MBI instructional sequence seems to have favored the mobilization of students’ alternative conceptions about global warming, coral reefs, and symbiotic relationships. In addition, it contributed to increasing the students’ awareness of the problem of global warming and its effects on an essential socio-ecological system, such as coral reefs.

Global warming and sea-level rise (SLR) induced by rising atmospheric CO2 concentrations can cause coral bleaching, death, and submergence of the world’s coral reefs. Adopting the GIS and RS methods, we modeled how these two stressors combine to influence the future growth of the atolls and table reefs of three archipelagoes in the South China Sea (SCS), based on geomorphic and ecological zones. A large-scale survey of the coral communities in Xisha Islands in 2014, Dongsha Islands in 2014–2016 and Nansha Islands in 2007 provided zone-specific process datasets on the range of reef accretion rates. Sea surface temperature and extreme (minimum and maximum) SLR data above 1985–2005 levels by 2100 in the SCS were derived from the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) models forced with the Representative Concentration Pathways (RCPs). Our model projected that: (1) the Xisha Islands and Dongsha Islands may have a better growth status, because the reef flat biotic sparse zone may be recolonized with hard coral and become a biotic dense zone; (2) the southern Nansha Islands reefs have a risk of stopping growing due to their earlier annual bleaching years. The increasing of water depths of these reefs is stronger in the RCP with more emissions. Our approach offers insights into the best-case and worst-case impacts of two global environmental pressures on potential future reef growth under a changing climate.

As the empirical evidence for the global warming hypothesis augments, not the least for Asia, it is time to take climate change more seriously, starting with major activities to bring down the CO2:s and guard against methane. It is no longer enough with small scale experimental activities, but a major policy push is necessary to get rid of coal, stone or wood, replacing it or constructing carbon capture facilities everywhere. Old polluting buses and trucks must be replaced urgently, diesel abandoned, and the closure of atomic plants stopped. South Asia and Eat as well as South East Asia have now to embark upon major big scale policies to stop deforestation and desertification, protect coral reefs and secure fresh water sources. Traditional renewables must be replaced by modern renewables. And the pollution from the immense car park has to be regulated somehow. What is now at stake for Asia at the most dynamic part of the globe is to fulfil Goal I and Goal II in the COP21 decarbonisation Agreement? And no government can be allowed to renege.
