Scientists used records from a nesting site to investigate a possible effect of global warming on swallows.
| First 10 years of the study | Last 10 years of the study | |
|---|---|---|
| Mean spring temperature in °C | 8.6 | 9.8 |
| Mean arrival date of the swallows | 24 April | 10 April |
Which conclusion is supported by these results?
The geographical distribution of the swallows changed as temperatures rose.
The nesting habitat of the swallows was flooded as temperatures rose.
The biodiversity at the nesting site decreased as temperatures rose.
The swallows' migration pattern changed as temperatures rose.
