4、is also about accessibility (presentation) and utility (guidance)predict, optimise and relax預(yù)測、優(yōu)化與放松預(yù)測、優(yōu)化與放松focus is on the climate and projected change 聚焦氣候與預(yù)期變化聚焦氣候與預(yù)期變化often assumes that we are adapted to “today”時常假定我們是在適應(yīng)時常假定我們是在適應(yīng)“今天今天”follows a linear model:遵循線性模式氣候預(yù)測遵循線性模式氣候預(yù)測focus is on gett

5、ing the climate “right” uncertainty remains a barrier to decision making “徹底徹底明白明白”氣候氣候不確定因素會對決策構(gòu)成障不確定因素會對決策構(gòu)成障礙礙tendency for decision and policy makers to hold off awaiting better climate information and there is a need to start over each time there is new projections 決策者與政策制定者有這樣一種傾向，他們會延時決決策者與政策制

6、定者有這樣一種傾向，他們會延時決策以等待更佳的氣候信息，因此，每當(dāng)有新的預(yù)期出現(xiàn)，就要從頭開始。策以等待更佳的氣候信息，因此，每當(dāng)有新的預(yù)期出現(xiàn)，就要從頭開始。climate projections氣候預(yù)期impacts影響adaptation適應(yīng)assess, adjust and review評估、調(diào)整與回顧評估、調(diào)整與回顧focus is on understanding the climate (and other) risks焦點(diǎn)在于認(rèn)識氣候（及其他）風(fēng)險(xiǎn)焦點(diǎn)在于認(rèn)識氣候（及其他）風(fēng)險(xiǎn)assumes that “today” may need some further adaptat
