Frontier Technologies to Protect the Environment and Tackle Climate Change





                                                       Longer, hotter periods will continue to become the
                                                       norm in many cities, making city life very taxing. The
                                                       ‘heat island effect’ will be exacerbated by concrete
                                                       surfaces  and  the  lack  of  greenery  in  many  cities.
                                                       Air  conditioning  systems  will  contribute  more  to
                                                       greenhouse gas emissions , making it urgent to find
                                                                            79

               Temperature, however, is just one indicator of climate change; changes in the global distribution of
               rainfall are also having major impact around the world. Rising sea levels – largely due to the thermal
               expansion of sea water and melting of the largest glaciers, like in Greenland and Antarctica – are
               another impact of climate change of deep concern for those living in low-lying urban coastal areas.
                                                                                                  81
               The global mean sea level reportedly rose 3.7 mm higher in 2018 than the previous year.  This is
                                                                                            82
               exposing coastal areas and islands to a greater risk of flooding and submersion. The resulting risks
               to transportation, especially in the case of coastal transport infrastructure, pose significant threats
               to global trade and development. International maritime transport carries over 80 per cent of the
               volume of world trade and provides access to global markets for all countries, including those that
               are landlocked. 83





































               For Small Island Developing States, which are already exposed to major natural hazards, the outlook
               is particularly alarming. Their critical reliance on coastal transport infrastructure, in particular:
               seaports and airports, worsens their susceptibility to climate change impacts such as rising sea-
               level and extreme weather events. These impacts threaten trade and disaster relief efforts, as well
               as international tourism, which is the crown jewel of economic development in SIDS that requires
               secure and reliable international transport connections. Yet SIDS, and other developing countries,
               have limited capacity to adapt and build the resilience of their transport infrastructure to cope with
