| Sydney heatwave, bushfires, seawall construction, renewable energy. |
Following is a review of climate change related events in Australia for the week ending 16/3/2025:
1. Heatwave and Bushfire Risks in New South Wales
New South Wales experienced a severe heatwave, prompting authorities to issue a total fire ban for Sydney due to elevated bushfire risks.
Temperatures soared, increasing concerns about potential fires across the region. Link
2. Debate Over Seawall Construction in Collaroy and Narrabeen
A seawall was constructed between Collaroy and Narrabeen, suburbs on Sydney's northern beaches, in response to significant erosion that threatened local properties.
This development has sparked debate among residents and experts regarding its long-term effectiveness and environmental impact.
Some coastal scientists and environmental groups warn that such structures might increase erosion and alter beach dynamics, while some residents feel it offers temporary security. Link
3. Criticism of the Coalition's Nuclear Energy Proposal
Dr. Jonathan Pershing, a former U.S. special envoy for climate change, criticised the Federal Coalition's proposal to adopt nuclear energy, labelling it the most expensive option compared to alternatives like solar power paired with battery storage.
He highlighted the global trend away from new nuclear projects due to high costs and lengthy implementation timelines, suggesting that renewable energy sources offer more cost-effective and reliable solutions. Link
4. Sydney's Record-Breaking Heat
Sydney faced potentially record-breaking heat, with temperatures reaching unprecedented levels for this time of year.
The city anticipated relief with an upcoming cool change, but the unusual heat underscores the increasing frequency of extreme weather events linked to climate change. Link
5. Australia's Progress Towards Climate Goals
The latest Quarterly Update of Australia's National Greenhouse Gas Inventory reported emissions at 440.6 million tonnes of CO₂-equivalent for the year up to June 2024, marking a 0.7% decrease compared to the previous year.
This reduction aligns with Australia's ongoing efforts to meet its climate commitments and transition towards a low-carbon economy. Link
