Our earth's climate is changeing. Heat waves are likely to be more frequent and longer-lasting, extreme rainfall will become more intense and frequent, and the global mean sea level will rise. In 2015, the Centre for Climate Research Singapore(CCRS) and the United Kingdom's Met Office Hadley Centre concluded Phase 1 of the Second National Climate Change Study. The study analysed Singapore's climate up to the year 2100 and projected that Singapore is likely to become warmer, experience more frequent and heavier storms, and face rising sea levels.
