| 1 | He dived in first and test the temperature of the water. | |
| 2 | These currents control more than water temperature. They transport distant marine life as well. | |
| 3 | The results have implications for lake ecosystems, which can be adversely affected by even small water temperature changes. | |
| 4 | Funny how sensitive humans are to just a few degrees difference in water temperature. | |
| 5 | Writing in the journal Nature, scientists say the decline appears to be linked to rising water temperatures. |
