I need to write a report on the impact of climate change on coastal cities. Can you provide an outline for this report? The report should have at least 4 sections, marked with "SECTION" X, such as: SECTION 1. Include a title in double angular brackets, such as <<Impact of Climate Change on Coastal Cities>>. Each section should have a title, and the content should follow the title. The response should contain at least 4 placeholders represented by square brackets, such as [city_name]. Finish your response with this exact phrase [ender]: "Please review and let me know if any adjustments are needed." No other words should follow this phrase.
