The latent super power in our energy grids | Clyde Mallinson | TEDxJohannesburg
TEDx Talks· 2025-12-12 16:51
Honestly, we couldn't have got the timing better than we've got it. Here we sit with our coal fleet due for retirement anyway. Some of it should have been retired already.So, it's due for retirement. And we sit in the middle of the biggest, most exciting disruption to the energy sector ever. The prospect of abundant, clean, renewable energy for everyone is no longer a dream.It's real. And the concept of people having access to uncapped electricity at no additional cost, it's it's transformative. Now the gov ...

Climate Change Supercharged Deadly Asia Floods, Study Finds
Insurance Journal· 2025-12-12 07:10
Core Insights - Climate change significantly exacerbated severe flooding in South and Southeast Asia, resulting in over 1,600 fatalities and approximately $20 billion in damages due to three tropical cyclones in November [1][2]. Climate Impact - Warmer Indian Ocean waters, approximately 0.2°C above long-term averages, contributed to the intensity of Cyclones Ditwah and Senyar by providing additional heat and moisture [2]. - Without human-induced climate change, ocean temperatures would have been about 1°C cooler, indicating a direct link between climate change and increased storm severity [2]. Urbanization and Environmental Factors - The combination of climate change, seasonal weather cycles, and rapid urbanization, along with widespread deforestation, intensified the flooding, with water levels exceeding expected heights during the monsoon season [3]. - Researchers noted that while flooding is typical during monsoon season, the levels reached in some areas were unprecedented, exceeding 14 to 15 feet [3]. Climate Model Limitations - Current climate models have struggled to accurately predict the rapid pace of climate change and its impacts, particularly since 2022, leading to economic challenges for insurers and financial firms [4]. - The inconsistency in major climate models regarding rainfall increases from the cyclones suggests a need for improved models that can better capture regional dynamics [3][4]. Historical Weather Analysis - An analysis by ClimaMeter indicated that meteorological conditions during Indonesia's floods were up to 7 millimeters a day, or 15%, wetter than historical averages, underscoring the influence of climate change [6]. - The attribution group expressed low confidence in their findings due to the rarity of similar events, but noted that natural climate variability played a minimal role in the floods [7]. Increasing Extreme Weather Events - Research indicates a growing trend of extreme rainfall events in Southeast Asia over recent decades, aligning with the findings of the recent floods [7].

The shift from finite capital to infinite resilience | Leanne Emery-Hunter | TEDxJohannesburg
TEDx Talks· 2025-12-11 17:12
Key Arguments - The current financial architecture is not designed for a world of constant crisis, reacting instead of anticipating risks [6] - South Africa needs hundreds of trillions of US dollars by mid-century to tackle climate change [7] - The Just Energy Investment Plan estimates a need of $98 billion over the next 5 years to transition to a low-carbon economy [7] - Of the $11.5 billion secured for the Just Energy Transition, only 7% is in the form of grants, while over half are loans [8] Financial Resilience & Investment Strategies - Financial resilience is defined as the ability of markets to adapt to and absorb shocks while maintaining sustainability and growth [6] - Catalytic capital is essential for absorbing risks and unlocking further investment [8] - The Galapagos Islands debt-for-nature swap demonstrates how layered funding models (donor grants, concessional loans, institutional investment) can turn debt into climate action [15][16] - South Africa's Green Outcomes Fund has leveraged 100 million rand in public money to create four times that amount in private sector funding for small green jobs [19] Recommendations for Systemic Change - Build capacity in communities for governance and finance, and in investors for local context [20] - De-risk resilience investments through guarantees, public funding, and concessional loans [21] - Make resilience attractive by lowering interest rates for climate outcomes and rewarding long-term sustainable views through policy and pricing [21] - Governments need to provide clear policy signals, structure catalytic funds, and simplify processes to facilitate the flow of funds to investable projects [23]

[music] [applause] Hello everybody. I've always seen the law as a powerful shield, a tool to protect the vulnerable and to uphold justice. And I grew up in a family of lawyers.My grandparents and my mother are all lawyers. And I decided to become a lawyer myself because I strongly believe in the power of law to effect change and to benefit society. But law does not always effect change and benefit society.The evolution of law is often shaped by profit motive and corporate interests. I've spent years in corp ...

[music] [applause] Have you ever felt a sudden rush of anxiety after seeing a climate headline like this. Global temperatures must fall by 1.5% degrees Celsius. Or we face irreversible catastrophe.Maybe it's a graph. Maybe it's statistics. Maybe it's news alert that make your stomach just drop.Me too. For years, I used to believe that all of the answer to climate solution is embedded in data. And of course, I still believe that.But that's not the whole story. What if the answer to our climate solution is al ...

The Power of Risk Thinking: Choosing Our Future | David Lallemant | TEDxChiangMai
TEDx Talks· 2025-12-11 16:24
Risk Analysis Framework - Risk is defined as the combination of hazard, exposure, and vulnerability, where hazard refers to extreme events, exposure describes what's in the path of those hazards, and vulnerability describes the fragility or resilience [4][5] - Understanding risk involves assessing the intensity and frequency of hazards, and quantifying the potential damage and repair costs [4][16] - The framework of hazard, exposure, and vulnerability can be used to quantify risk in financial or operational terms, making it actionable for decision-makers [13] Disaster Risk Management & Solutions - Traditional access to risk information has been limited, primarily available to insurance companies in wealthy countries, highlighting a gap in global risk awareness [13][14] - High-resolution risk models, developed using AI and remote sensing, can cover the entire world, addressing flooding, tropical cyclones, extreme heat, and more [15] - Resilience should be viewed not only as avoiding losses but also as creating value, such as improving quality of life and generating revenue [19][23] - While hazards are often difficult to control, exposure and vulnerability are more manageable, allowing for interventions like building away from flood plains or elevating critical assets [17][18] Future Trajectory - Climate change is generally increasing the frequency of extreme events, leading to a growing risk trajectory [24] - Risk models provide a map to navigate towards a resilient future, enabling informed decisions and steering towards safety and prosperity [25]
