Long-lost records confirm rising sea level

The discovery of 160 year old records in the archives of the Royal Society, London, has given scientists further evidence that Australian sea levels are rising. Observations taken at Tasmania’s Port Arthur convict settlement 160 years ago by an amateur meteorologist have been compared with data from a modern tide gauge. “There is a rate of sea level rise of about 1mm a year, consistent with other Australian observations,” says Dr David Pugh, from the UK’s Southampton Oceanography Centre.
