The Great Barrier Reef: breaking news from Australia – Aug 2018

A $400 million plan to rescue the Great Barrier Reef has been announced this week by the Australia government when issuing their federal budget.  It will include $60 million to tackle run off from farms, fund new research on coral bleaching and deal with the destructive crown of thorns starfish.

High ocean temperatures, caused by global warming have already ravaged the reef. Environmentalists have described the plan as totally inadequate, as it does not deal with the factors causing climate change, such as industrialisation and the burning of fossil fuels. A particular sore point for Australians campaigning for the reef is government support for the Adani coal mines in mid-Queensland.

The maps below show the location of the proposed mines in relation to the Great Barrier Reef.  Australia is one of the largest sources of coal in the world.

30th August 2018:

The Fight for our Reef campaigners have issued a new mailing, as they are extremely concerned about their new PM, who is a climate change denier.  The text of their recent email is as follows:

Less than a year before he was sworn in as our latest Prime Minister, Scott Morrison famously waved around a lump of coal in Parliament House, ridiculing our concerns about the impact of coal on our climate, and by implication our Reef. Now Australia’s new PM says he is “technology-agnostic”, which is code for continuing support for coal. Now more than ever, it’s time for urgent action on climate change. Will you join the global day of action on 8 September?

Coal in parliament? No way! Let's rise for climate, rise for our Reef!

Last week we watched the Liberal Party dump their long awaited energy policy to cut carbon pollution and elect Scott Morrison as our new Prime Minister.

This week the new Prime Minister has evaded any discussion on climate change, including its link to the devastating drought hitting Australia. He is also under pressure to ditch the Paris Agreement, from the same climate sceptics within the party who scuttled Malcolm Turnbull’s leadership.

While politicians in Canberra are shunning their climate responsibilities, the rest of us are living with the devastating effects of climate change gripping Australia and hitting our national icons like the Great Barrier Reef.

It’s time to take it to the streets. It’s time our government understands that we are sick and tired of climate change being a political football. We want strong action on climate change and we want it now.

5th September 2018 update from “Fight for the Reef”:

BREAKING: The Queensland Government has announced it is prosecuting Adani for releasing highly polluted water into the Great Barrier Reef World Heritage Area. 

 

Great news! The Queensland government has announced that it is prosecuting Adani for breaching it’s pollution licence by 800% in Great Barrier Reef waters.

Adani must now go to court to defend their actions. If found guilty they could face far greater penalties, including a suspension of their suitability to operate at Abbot Point.

We are pleased that the Queensland government is holding its ground and prosecuting Adani for the unauthorised release of concentrated coal-laden water into the Great Barrier Reef World Heritage Area at Abbot Point. While the outcome of the court case is too early to call, this is a big moment to celebrate. Thank you to everyone who contacted the Premier and Minister for the Reef, and who spread the word by sharing our video on Adani’s shonky reputation.”

The Truth about Heatwaves: 2

In the first of my blogs about heatwaves, I focused on the heatwaves that are occurring on land more and more often and the effects these are having on terrestrial life forms, including humans.

In this blog, I will describe the effects of heatwaves on the oceans, which have doubled in the last 30 years. Up till now, perhaps we have been unaware that heatwaves do affect the oceans and the life that in them. In other blogs, and in my book, I have talked about the destruction of coral as the seas warm, causing coral bleaching.  It is also known that, after the 2016 heatwave in Australia, one third of the coral in the Great Barrier Reef died.  Many of the beautiful fish who live in coral reefs, and are dependent on them, will be affected by the death of corals.

In yet another blog, I have referred to how global warming is affecting the gender of sea turtle eggs, developing in the hot sands where they have been laid, so that now the majority (99%) of the hatchlings born in Northern Australia are female.

Swiss scientists have been recording sea water temperatures over the period 1982-2016 and have found that the number of ocean heatwaves has doubled.  Marine heatwaves can last for several days, and even weeks, as water absorbs heat more readily than air and releases it more slowly.  Dr Thomas Frölicher, of the University of Bern in Switzerland, is the climate scientist who has conducted this study. He believes that the trend of increasing ocean heatwaves will only accelerate with time. Prolonged periods of extreme heat in the oceans can damage kelp forests as well as coral reefs, and harm fish and other marine life. Some sea creatures have evolved to survive in a very narrow band of temperatures compared to creatures on land.  Some free swimming fish can move to other places when the sea becomes too hot for them but, with fixed organisms like coral and kelp forests, there is no opportunity to move.

If the plankton in the sea, as well as kelp forests, are affected by warming temperatures, many marine creatures will lose their main source of food.
