Arrange the sentences into the correct order.
Put the sentences in the correct order:
- This shift has allowed scientists to compile a global picture of ice loss in a fraction of the time the old method required.
- Satellite imagery has since replaced most fieldwork, letting researchers measure the boundaries of thousands of glaciers simultaneously from orbit.
- This method produced accurate readings for individual glaciers but was far too slow and labour-intensive to apply across an entire mountain range.
- For much of the twentieth century, scientists tracked glacier size by physically walking the ice each summer and recording where the edge had retreated.
- Glaciers act as natural reservoirs of fresh water, and their gradual melting or growth offers one of the clearest signals of long-term climate change.
