Our reefs love global warming


Andrew Bolt:

Professor Ove Hoegh-Guldberg is the world expert in forecasting warming doom for the Great Barrier Reef – crying wolf again and again.

This Ove Hoegh-Guldberg bloke, as Bolt readers would know, has been trying to scare the kiddies with tales of reef doom and gloom caused by global warming for years  now.

Thus, it was refreshing to read this in the Australian today (and it’s not the first finding of this sort by any means, either).

A GOVERNMENT-RUN research body has found in an extensive study of corals spanning more than 1000km of Australia’s coastline that the past 110 years of ocean warming has been good for their growth.

The findings undermine blanket predictions that global warming will devastate coral reefs, and add to a growing body of evidence showing corals are more resilient than previously thought, up to a certain point.

Love the little disclaimer at the end there, but let’s move on.

The researchers found that, contrary to their expectations, warmer waters had not negatively affected coral growth. Quite the opposite, in fact: for their southern samples, where ocean temperatures are the coolest but have warmed the most, coral growth increased most significantly over the past 110 years. For their northern samples, where waters are the warmest and have changed the least, coral growth still increased, but not by as much.

And I love how it’s the government-run Australian Institute of Marine Science who made these findings. That doesn’t fit the narrative!

😛

One has to wonder, but. Why did it take a whole swathe of scientists to work out that coal reefs like warm water more than cold? One would think that’s kind of obvious.

The article goes on to state that our fishies love warmer water, too. Hardly a surprise for cold-blooded creatures whose metabolisms (growth rates) benefit from this. In fact, fish farms often make the water warmer to obtain bigger yields.

UPDATE

Now, there’s dispute as to whether our oceans actually are warming (like the above article states) or not – and you can look that up yourself if my claim is really such a pressing issue for you – but to this layman, the fishies can handle it anyway, just as they’ve handled temperature, sometimes acute temperature fluctuations in the past. After all, our fishies can handle night and day and migrate from warmer to cooler to warmer waters all the time.

What would actually worry me, or at least intrigue me is if ocean temperatures suddenly became static.

Besides, apart from a few mad Russians, who likes swimming in cold water?
