465: New York City’s record-setting AQI on Wednesday, June 7, by The New York Times measure.

377: The average AQI in New York on Wednesday.

39: New York’s average AQI on June 7 of last year.

320: The average AQI of New Delhi, India, in November 2022 — one of the city’s best Novembers in years.

    When is an announcement less an announcement than a confirmation?

    The National Oceanic and Atmospheric Administration’s 2024 hurricane season outlook, issued Thursday morning, might be one such case. For the past several weeks, hurricane agencies around the country have been warning of an extremely active, potentially historic season due to a confluence of factors including the record-warm water in the Atlantic Main Development Region and the likely start of a La Niña, which will make the wind conditions more favorable to Atlantic storm formation. With the Atlantic Hurricane Season set to start a week from Saturday, on June 1, NOAA has at last issued its own warning: There is an 85% chance of an above-average season, with eight to 13 hurricanes and four to seven of those expected to be “major” Category 3 or greater storms.
