The tide is turning for turtles
- Environmental Impact Assessment
A study published in the latest issue of Current Biology has found that green sea turtles born in areas of heated water and sand around Australia’s Great Barrier Reef are 99.8% female.
In turtle biology, different temperatures dictate their sex, with cooler temperatures producing more male hatchlings and warmer areas producing more females. The change in sea and sand temperature is thought to be a consequence of climate change.
It is not yet clear how the extreme sex ratio will affect sea turtles’ future, but there are concerns that this could create something of a time bomb.
Michael Jensen, the study’s lead author, said: “What happens in 20 years’ time when there are no more males reaching adulthood? Will there be enough breeding males to sustain the population?”

The Environment Bill returned to Parliament following the Queen’s speech and is making progress through the House of Lords.
In June 2021, the UK’s governing Conservative Party lost a by-election in Chesham and Amersham, a seat it had held for 47 years. The principal reasons reported as the cause of this defeat were proposed planning reforms and the promotion of housebuilding on greenfield sites across the south of England.
As we celebrate the 10-year anniversary of the EIA Quality Mark, IEMA can announce that, during the past 12 months, the scheme has undergone a thorough review of practice, including stakeholder consultation with registrants and assessors, in order to improve it.
The delivery of effective outcomes for the environment, communities and development is a team effort, and more so when it comes to consenting projects that undergo Environmental Impact Assessment (EIA).
