More Barrier Reef scaremongering

Dangerously rapid warming, as you can see

Dangerously rapid warming, as you can see

Whenever things are a bit slow, and the alarmists are a bit desperate, they throw in a story about some cuddly creature becoming extinct, koalas or possums or polar bears, or in default, that great Aussie icon, the Barrier Reef. So here we go again, with the same ol’ same ol’ story rehashed and spun slightly differently:

THE Great Barrier Reef has only a 50 per cent chance of survival if global CO2 emissions are not reduced at least 25 per cent by 2020, a coalition of Australia’s top reef and climate scientists said today.

The 13 scientists said even deeper cuts of up to 90 per cent by 2050 would necessary if the reef was to survive future coral bleaching and coral death caused by rising ocean temperatures.

We’ve seen the evidence with our own eyes. Climate change is already impacting the Great Barrier Reef,” Terry Hughes, director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University, said in a briefing to MPs.

Australia is one of the world’s biggest CO2 emitters per capita [What relevance is that? We produce less than 1.5% of global emissions – Ed], but has only pledged to cut its emissions by five per cent from 2000 levels by 2020. The Government said it would go further with a 25 per cent cut, if a tough international climate agreement is reached at UN climate talks in Copenhagen in December, but this is looking increasingly unlikely with legally binding targets now off the agenda.

[Cue violins]This is our Great Barrier Reef. If Australia doesn’t show leadership by reducing emissions to save the reef, who will?” asked scientist Ken Baldwin.

The reality, of course, is that sea surface temperatures around the GBR have hardly risen at all, the reef has been here for hundreds of thousands of years, and has been through more warmings and coolings that Terry Hughes or Ken Baldwin between them have had hot dinners. And it’s still here. And it will still be here long after Terry Hughes and Ken Baldwin are pushing up the daisies. Why? Because reefs adapt. Unlike humans, who panic and throw trillions of dollars at a solution that won’t work.

  1. If that graph is correct, then we should get a please explain form those so called experts. Where did you get it from Simon?

  2. It’s from John McLean’s site here. He prepared the graph from the raw NOAA data (available online). I have not checked the graph against the raw data, but I have no reason to suspect that it would not be correct.

  3. Thanks for the info Simon, like your new site.
