PARIS (AP) — The Latest on Earth Hour (all times local):

8:30 p.m.

The City of Lights has turned off the Eiffel Tower’s nightly twinkle to mark Earth Hour, a worldwide campaign to urge more action against climate change.

Paris Mayor Anne Hidalgo dimmed the lights Saturday on the city’s most famous monument for an hour starting at 8:30 p.m. (1930 GMT). The tower’s lights normally dominate the Paris skyline after dusk, but are dimmed for major world tragedies and events like Earth Hour.

French President Emmanuel Macron has campaigned to “Make Our Planet Great Again,” but has faced criticism from those who say his efforts to cut greenhouse gas emissions hurt the poor and others who say that his climate policies aren’t ambitious enough.

Earth Hour events have spread to more than 180 countries since the movement started in 2007.
