New York's skyline has undergone significant changes, with some outlets noting dramatic transformations in Manhattan's skyline since the 9/11 attacks. However, it is unclear what specific changes are being referred to, as some reports appear to focus on environmental and development issues in the city, while others discuss changes to the city's ferry system or lawsuits against oil companies. The nature and impact of these changes on the city's skyline are also being debated, with some expressing concern about the potential negative effects of new developments.
