Response to John...
1. What I said is true. Males travel for thousands of miles and hang out at the nearest nesting ground mating with any females who return to the grounds where they were born. Males don't return. So any one nesting area won't be at risk for population collapse just because of a trend of female clutches. And males are very aggressive, mating with as many females as they can catch. So the population thrives better when there are lots of females around.

2. I would challenge their methodology. My point is valid. Given the length of the season, there's no way temps average over 88 for the entire season triggering all female clutches. Their sampling requires taking eggs into the lab and maturing them far enough to sex them. In other words, sample size is too low to make sweeping statements like 'only females' born in any year. They didn't provide the proper context with the sampling size data. Weak.
3-7 the most important takeaway is that there's never a mix of females and males. Its either/or. All female or all Male. The only exception is at 88 degrees and then it's a single male surrounded by 100 or more females. Point being, they make this big deal over all females, but that's just normal.
In other parts of the world, it's all males, they find each other and make it work. Lots of hyperbole with no proof and no global population decline to back it up. Weak science.
8. They do clearly and inaccurately state that turtles are not keeping up with climate change. Unsubstantiated nonsense.
And yes, I am fine with animals adapting by migrating to places that better meet their needs. That how it happens throughout history. It's not sad, its resilience at it's best and most wonderful. Growing up in Marylander, I never saw half of the animals I see regularly today... hummingbirds, Canadian geese, eagles, deer, coyotes, bear, foxes, owls, pelicans, turkeys, etc. I love having them and more around knowing things change over time. I hate when man made pollution affects wildlife like it has. I am a huge conservationist in that regard and really want clean rivers, streams and lakes, and especially want clean oceans. That said, co2 is not a pollutant. And a slightly warmer world is much better for plants, crops and most animals. And I am not convinced that man has as much influence over climate change as many think. There are some seriously smart climate scientists who shape my opinions. Like Judith Curry and Richard Lindzen, just to name 2. I do believe we are in a warming cycle. And I believe we're entering into a cooling cycle for the next 20-30 years based on the solar minimum.
