Coral reefs have long been regarded as one of the earliest and most significant ecological casualties of global warming. And as ocean temperatures continue to rise, mass bleaching and die-offs have gone from being rare to a somewhat regular occurrence.

Aside from climatic changes, human activities are no doubt damaging reefs beyond repair. Overfishing, pollution and coastal development are at the top of the list of chronic stressors. And meanwhile, reefs are also dredged or sandblasted for their limestone or to improve access and navigational safety in some areas.

On this episode of Climate Connections, Vrikro Yu, CEO of Archireef shares her personal story of witnessing the disappearance of a small patch of coral community in just two months during her research project and how that led to the founding of her climate tech venture that’s working to restore fragile marine ecosystems by using 3D printing technology and some good old-fashioned terracotta.

Archireef, which was founded in 2020, made the Forbes 100 To Watch List in 2023. Vriko was also recognised as a Top Innovator at the 2023 World Economic Forum in Davos.

2024 is "virtually certain" to be the hottest on record. In recent months, the world has seen back-to-back hurricanes, catastrophic flooding, devastating typhoons and severe drought.

It is against this backdrop that global leaders gather at the COP29 UN climate summit in Baku, Azerbaijan, where a draft text of the new climate finance target was published. The finance agreement - also known as the New Collective Quantified Goal - would apply when the current US$100bn per annum target ends in 2025, and will be crucial for scaling up finance for climate action around the world.

With more than a week of talks ahead, the final outcome is still uncertain. However, the text contains many options still under consideration, as world leaders and negotiators work out a new financial target to support developing countries in their climate actions post-2025.

On this episode of Climate Connections, Sophie Sirtaine, CEO of CGAP - an international partnership housed in the World Bank Group, dedicated to promoting inclusive financial ecosystems - weighs in on what’s at stake.

Until now, geologists have been divided as to whether this superdeep, superhot resource can be tapped.

Rock under high temperature and pressures - more than 373 degrees Celsius and 220 bars of pressure - is ductile, or gooey, as opposed to a smashable stone from your backyard.

So far, data shows that rock that fractures at superhot conditions can be ten times more permeable than rock that fractures at conditions closer to the Earth’s surface, and can also deform more readily.

Scientists have found that in the Taupō Volcanic Zone, supercritical conditions are as shallow as 4 km, making it one of the rare places in the world where supercritical development is both accessible and technically feasible. So far, only Iceland, Japan, the United States and Kenya have successfully drilled superhot wells.

On today’s Climate Connections, Sheena Thomas, Interim General Manager Research Strategy and Partnership from GNS Science shares her insights on the economic potential and viability of superhot geothermal in New Zealand, and why proper environmental impact studies and collaborations with local indigenous Maori communities are absolutely critical in ensuring minimal environmental impact. She’s also a speaker at the Singapore International Energy Week this year.

GNS Science is leading a multi-year research programme 'Geothermal: The Next Generation’ - to investigate New Zealand’s ‘supercritical’ (high temperature/superhot) geothermal conditions and evaluating the economic opportunity for supercritical geothermal heat and electricity generation in New Zealand.

Algae are microscopic organisms that live in aquatic habitats and they use photosynthesis to produce energy from sunlight, just like plants. So far, there are over 50,000 species of living algae documented currently. And one thing that people sometimes forget is that algae are the base of many food webs and are an integral part of a healthy aquatic ecosystem.

But, algae can also grow out of control if the water around them contains too many nutrients, resulting in harmful algal blooms. And did you know that toxins from these harmful algal blooms could get kicked up into the air as airborne algae?

With the focus on climate change growing, scientists are continuing to document the effects of climate change on algae, and how airborne algae in turn interact with our environment.

On this episode of Climate Connections, Mickey Rogers, Pauling Fellow and Chemist, Pacific Northwest National Laboratory, who is researching airborne algae and its impact on atmospheric processing, shares her insights. She's currently also developing new methods of aerosol generation and online gas flux monitoring of biological cells including acoustic levitation of small particles.

Industrial waste makes up at least 50% of waste generated globally. And much of that waste is the result of poor quality products from manufacturing processes, as well as the sheer complexity of manufacturing and supply chain management.

As consumer awareness about the environmental impacts of waste increases, recycling is expected to grow considerably in the coming years. By 2032, the global waste recycling services market is forecast to have surpassed a value of US$90 billion, registering a compound annual growth rate of 4.7 percent during the forecast period 2023 to 2032.

But cost is often an issue. So, what can be done to scale up recycling within industries?

On this episode of Climate Connections, Susie Burrage, President, Bureau of International Recycling, who will be actively involved in the World Recycling Convention, held in Singapore from 28th to 29th October, shares her perspectives of being a fourth-generation recycler.

Nature films tell the stories of the world's flora, fauna, and landscapes - often a journey into the secret lives of what exists around us. These stunning visual tales show us how we are interconnected with nature in many ways. This, in turn, allows us to better understand the current conversations about climate change, sustainability and biodiversity, and put us in a better position to be agents of hope and change.

That’s exactly what the inaugural ‘Earth in Focus’ Singapore Nature Film Festival 2024 hopes to achieve. Running from 1st to 3rd November this year, the festival will showcase local and international films, photography and ecological art exhibitions, as well as workshops run by conservation NGOs - covering a wide range of conservation topics, from ocean and land conservation to water scarcity and technology for conservation.

On this episode of Climate Connections, Daphne Ong, Conservationist & Festival Director of Earth In Focus, and Andy Ridley, CEO of Citizens of the Reef & Co-founder, Earth Hour share their insights ahead of the festival.

Nature is our life support system, but right now, it’s in trouble. WWF’s latest Living Planet Report reveals that the average size of wildlife populations have declined by a staggering 73% since 1970, providing a stark warning “that the world is fast approaching dangerous tipping points”.

Habitat loss and degradation, driven primarily by our food system is the most reported threat to wildlife populations, followed by overexploitation, invasive species and disease.

With Australia’s role as a regional food supplier growing in importance as global food demand surges, an Australian farmer-owned mutual - Regen Farmers Mutual - is working hard at giving landowners greater access to the growing environmental goods and services markets as the world transitions to net zero.

More than 80 farmers, conservationists and landcarers behind Regen Farmers Mutual have designed a new brokerage model to reduce transaction costs and enable farmers to aggregate their market power to sell environmental services. They are raising $51 million from mining and energy players to fund a series of regenerative farming projects. The mutual has agreed to $100 per unit for the first 1,000 of 18,500 available carbon credits across 750 hectares of land.

On this episode of Climate Connections, Rohan Clarke, Co-director, Regen Farmers Mutual shares how they’re tapping on carbon markets and regenerative farming to preserve their lands.

About 180,000 chimpanzees, gorillas and bonobos could be directly or indirectly threatened by current and future mining projects for these transition metals, particularly in West Africa.

With the world focusing its attention on clean energy transition, a boom in African mining activity is expected as critical minerals such as copper, lithium, nickel and cobalt are needed for clean energy technologies such as wind turbines and electric cars. This surge in demand is driving destruction of tropical rainforests which are critical habitats for Africa’s great apes.

In a recent study, researcher Jessica Junker and a team of scientists found that the overlap between mining exploration and preparation areas and important ape habitats was particularly high in West Africa, especially Guinea.

On this episode of Climate Connections, lead author of the study, Jessica Junker, Researcher, Re:wild shares her insights on the delicate balance.
