BBC Play Green Turtle Climate Card–But Ignore The Real Threats

This is just a rehash of an old story, which I covered here three years ago. It is based on the fact that warmer sand temperatures lead to faster incubation and a greater proportion of females.

Green turtles are found worldwide primarily in subtropical and temperate regions of the Atlantic, Pacific, and Indian Oceans, and in the Mediterranean Sea. It is absurd to suggest that there is an ideal temperature for them.

They have also been around for 100 million years or so, and flourished through massive climatic changes, so are hardly likely to be inconvenienced by a half a degree rise in temperature.

But what about the premise that 99% of baby turtles are female? The dopey BBC reporter calls this “devastating”, as if they were humans. In reality one male turtle will mate with many females, so more females equates to more eggs. Furthermore faster incubation means a higher survival rate. There is a very good reason why green turtles thrive in hot places such as Queensland, rather than somewhere like Blackpool. It really would be catastrophic if temperatures dropped, and there were fewer females.

Even if some beaches like Heron Island did become too hot, others in cooler latitudes would quickly become more suitable. Just as with all animal life, there is nothing in nature which says turtles have to to stay in the same location for ever. Populations ebb and flow as conditions change.

The tragedy is that there are very real threats to green turtles, as NOAA explain:

Needless to say, they have to mention future climate change, but the other items listed are real and threatening now. Proof of this lies in the fact that turtle populations are increasing in some Pacific Islands, thanks to conservation efforts.

By focussing on climate change, we lose sight of these other threats. It is a pity that the BBC reporter did not ask the useless WWF bimbo about these.
