## In brief

- Some estuaries on Australia's east coast already reach about 98°F (37°C) in summer.
- That is hotter than the harshest projections for the end of this century, according to the source.
- Fish in these estuaries continue to feed, grow, and get caught, despite the heat.

## Why it matters

Estuarine fish living near their thermal limits show that current heat tolerance may be higher than some climate projections assume, which matters for forecasting how marine species will respond to warming.
