Is it already too late for coral?

31 May 2005
It may already be too late to stop rapid climate change. The results will be terrible for coral reefs and other life systems.

So argues Thomas Goreau of the Global Coral Reef Alliance today on openDemocracy.

One of Goreau's central concerns is that models of the world's climate tend to greatly underestimate positive feedbacks - that is, effects that amplify themselves or other phenomena over time, like a microphone picking up noise from a speaker.

Is Tom Goreau making too extreme a case? openDemocracy welcomes a careful, evidence based response.

If he's right a more aggressive approach to reducing greenhouse gas emissions will be needed than the one reported to be on the table for the G8.

And even if the international community does agree to cut emissions, increased spending on ways to counteract the effects of changes already underway is likely to necessary.

Tom Goreau suggests "Biorock" for coral reefs. A loose analogy could be drawn with actions needed to protect another massive ecosystem, the Siberian forests (continent wide rather than ocean wide).

Forest fires in Siberia reportedly increased tenfold in the last 20 years and could again rage out of control this summer, according to Tim Radford in the 31 May Guardian. But in both cases - reefs and forests - the paths to wiser management and even (should climate change permit) restoration and not totally hidden, however hard they may be.

Stop the secrecy: Publish the NHS COVID data deals


To: Matt Hancock, Secretary of State for Health and Social Care

We’re calling on you to immediately release details of the secret NHS data deals struck with private companies, to deliver the NHS COVID-19 datastore.

We, the public, deserve to know exactly how our personal information has been traded in this ‘unprecedented’ deal with US tech giants like Google, and firms linked to Donald Trump (Palantir) and Vote Leave (Faculty AI).

The COVID-19 datastore will hold private, personal information about every single one of us who relies on the NHS. We don’t want our personal data falling into the wrong hands.

And we don’t want private companies – many with poor reputations for protecting privacy – using it for their own commercial purposes, or to undermine the NHS.

The datastore could be an important tool in tackling the pandemic. But for it to be a success, the public has to be able to trust it.

Today, we urgently call on you to publish all the data-sharing agreements, data-impact assessments, and details of how the private companies stand to profit from their involvement.

The NHS is a precious public institution. Any involvement from private companies should be open to public scrutiny and debate. We need more transparency during this pandemic – not less.


By adding my name to this campaign, I authorise openDemocracy and Foxglove to keep me updated about their important work.
