17. Conclusions Climate is changing, no doubt It will get warmer, more arid in most subtropical areas: water problems Ocean will get more acidic: extinctions Mitigation is imperative, but adaptation must play a role Coal burning is the main emitter of CO 2 world-wide We need market mechanisms to curb it Poor countries will suffer most because of vulnerabilities: migration, war The really difficult problem is with problems that involve values we cherish, but cannot be quantified.
