Right whales born in 1981 grew a metre longer than they do today

Surveillance of right whales in the North Atlantic show that individuals born today will grow to be 1 metre shorter, on average, than whales born in the early 1980s.
Joshua Stewart at the National Oceanic and Atmospheric Administration in San Diego, California, and his colleagues have used surveillance data collected from aircraft and drones to investigate how North Atlantic right whales (
Eubalaena glacialis) have changed over time.
The whales have been monitored consistently for decades, and researchers can identify individuals and know when each was born. Stewart’s team collected 202 length measurements of 129 of the whales born between 1981 and 2019: 133 measurements were taken from aircraft between 2000 and 2002, and 69 measurements were obtained using remotely operated drones between 2016 and 2019. ....

Coastal Georgia Ecosystem Report Card Scores Georgia's Coastal Environment B+

An annual report measuring the health of coastal Georgia’s ecosystem released today shows a slight decline from last year in overall scores, but most indicator trends remain positive.
The Coastal Georgia Ecosystem Report Card scored the state’s coastal environment at a “B+”, or 77 percent, a three-point decrease from last year, according to the Coastal Resources Division (CRD) of the Georgia Department of Natural Resources (DNR), which commissions the report.
“While we’re always striving to improve our scores, this slight decrease does not represent a concern at this point in time,” said Jan Mackinnon, a CRD biologist who oversaw the report. “Slight changes in environmental factors, including weather patterns, wildlife migration, and data collection can lead to different scores each year. The report still ranks Georgia’s coast in moderately good health, and we’re confident in the long-term trends.” ....
