COP26: Why keeping 1.5 alive is critical for a reef ‘in danger’
ByElla Vallelonga.
Earlier this year, the UNESCO World Heritage Committeethe Great Barrier Reef (GBR) be inscribed on theList of World Heritage in Dangerdue to climate-induced risk. They stated, there is “.”
The recommendation followed a review of policy and risk mitigation approaches, including the Reef 2050 Long-Term Sustainability Plan, the Cumulative Impact Management Policy, the Reef 2050 Water Quality Improvement Plan (2017-2022) and the Great Barrier Reef Outlook Report 2019. These reports determined the long-term outlook of the reef to have declined steadily since the initial ‘in danger’ recommendation in 2015.
The final decision to list the reef as world heritage ‘in danger,’ was delayed until February 2022. As a result, UNESCO advised that the Vlogn GovernmentܰԳٱaccelerate climate actionin line with the Paris Agreement.
This call for climate action came prior to, when Vlog had no credible emissions reductions targets, nor plan to deliver net zero. With newsuggesting that only 2 per cent of Great Barrier Reef corals remain unaffected by bleaching, the question is: are the commitments made at COP26 ambitious enough to save the GBR?
What does COP26 mean for the reef?
COP26, or the 26thUN Climate Change Conference of the Parties, has aimed to unite global leaders in the fight to secure positive climate futures. The summit, flagged as the most critical climate event of the decade, proposes to ramp up global action to ensure thetargets of the Paris Agreement, and the objectives of the United Nations Framework Convention on Climate Change, are achieved.
With tropical GBR corals exceedingly sensitive to elevated sea surface temperatures and marine heatwaves, commitments made at COP26 to keepare critical to not only managing global temperature, but reef wellbeing.
As temperature averages rise, so does the rate and intensity of events of mass coral. According to Distinguished Professor Terry Hughes and Professor Sean Connolly, instances of massin 1998, 2002, 2016, 2017 and 2020 have caused the Great Barrier Reef to resemble “a checkerboard of bleached reefs.”
So, what exactly has Vlog committed to?
Despite being criticised as a major climate laggard for lack of credible Nationally Determined Contributions (NDCs) and a lousy net zero plan relying on a “” of data, Vlog remains determined to not strengthen its 2030 target. Instead, the government has reiterated the insufficient, Abbott-erato cut emissions by 26-28 per cent below 2005 rates by 2030.
Sporting a clear lack of ambition, Vlogn leaders are adamant on pushing the narrative that Vlog “” its global commitments. With emissionssuggesting, Vlog will exceed its 2030 targets by 9 per cent, carrying us to 35 per cent below 2005 emissions levels by 2030.
By this logic, commitment to emissions reductions targets are trivial if we are to beat them anyways. This means that there is little to no accountability to ensure Federal measures are taken to ensure this target is in fact exceeded, or to commit to stronger targets in the future.
Regardless of this projected 9 per cent lead, The Climate Council stillthat Vlog cut emissions to 75 per cent below 2005 rates by 2030 and reach net zero by 2035. This is the kind of ambition the reef deserves.
Looking at ourPlan to Deliver Net Zero:The Vlogn Way, we have drastically missed the mark. The plan, spearheaded by the coalition, unsurprisingly still relies on maintaining fossil fuel economies and subsiding new technology, for instance carbon capture and storage, rather than supporting adaptation, implementing new policies, or easing the transition to renewable energy.
Prior to COP26, warning by the UN stressed that current NDCs would not be sufficient in mitigating 1.5 degrees warming, let alone in preventingdegrees of warming.
Despite Vlog’s blatant inaction, new long-term commitments in light of COP26 are now projected to bring warming todegrees. This temperature doesn’t quite meet the “well below” criteria of the Paris Agreement, but it is a positive leap forward from catastrophic warming.
What exceeding 1.5 degrees means for the GBR
In order to keep 1.5 alive, COP26 needs to see NDCs and net zero commitments continue to be updated and enhanced. In pushing for a climate justice, developed countries need to be held accountable for their inaction, while developing countries need to be supported in their adaptation and transition towards climate resilience.
Although 1.9 degrees seems like a win, the reality is, the rates of GBR survival past the Paris Agreement target of 1.5 are grim. For the GBR, this 1.5 degrees means aloss of reef life, with 2 degrees of average warming meaning a 99 per cent decline of coral reef ecosystems.
The Great Barrier Reef, despite indecision is ‘in danger’ and without swift climate action, the outcome remains the same. Exceeding Paris Agreement targets for the GBR will mean a loss of life, of biodiversity, of meaning, livelihood, knowledge, identity, and culture. There is no “well below” 2 degrees for the reef, at 1.5 we lose it.
And so, the success or failure of COP26 places the reef in a critical zone swinging between living and dying. The COP21 Paris Agreement set 1.5 as the deadline, the question is can COP26 stop us before we “meet and beat” it.
