Inconvenient truths in The Guardian: As CO2 has increased, fish stocks have improved, species diversity in estuaries is up, rate of sea level rise has evidently *decreased*

British seas: More fish, cleaner and greater biodiversity, says Defra | Environment | The Guardian

Thousands of holidaymakers heading to British beaches this summer will be cheered by a major government report into the state of the UK's seas. Coastal waters are getting cleaner, fish stocks are improving and species diversity in estuaries is increasing, according to the most authoritative examination ever carried out of UK seas.

But while the Department for Environment Food and Rural Affairs study boasts of "significant improvements" since the last such report in 2005, it also paints a picture of an environment being rapidly affected by a warming world. Seas around the British Isles are higher, warmer and more acid, it says, and coastal litter levels are at a record high.

Climate change is also causing sea levels to rise, with the mean sea level rising by 1.4mm per year in the 20th century. While slower than global growth of 1.7mm per year in the same period, the rise has not always been steady - in the 1990s, it was going up by 3-4mm each year.
