I want to know the answer to the following question:
When did sea levels reach their current highth?
All the background I'm provided with is that "As this ended, the central Irish Sea was deglaciated and the English Channel flooded, with sea levels rising to current levels some 4,000 to 5,000 years ago, leaving the British Isles in their current form.". Is that enough to answer the question?
Answer: yes
