As part of her doctoral research, Dr. Marathayil authored a significant scientific paper titled “The Role of Northern Arabian Sea Surface Temperature Biases in Model Simulations and Future Projections of Indian Summer Monsoon Rainfall.” This study was one of the first of its kind to demonstrate how systematic sea‑surface temperature (SST) biases in the northern Arabian Sea critically affect climate‑model simulations of the Indian Summer Monsoon (ISM). Her findings showed that even small warm or cold biases in this region can lead to large errors in monsoon rainfall projections—directly influencing forecasting accuracy for the Indian subcontinent. By identifying and quantifying these SST‑related errors, her research provided a strong scientific basis for improving rainfall prediction models, enabling better monsoon forecasting and more reliable climate‑risk assessments for agriculture, water management, and disaster preparedness. This work strengthened the understanding that correcting temperature

Bridging climate science, community development, and financial resilience to build a safer and fairer world.....

Climate Intelligence Must Become the Currency of Global Finance The world is entering a decisive decade where climate reality and financial reality can no longer exist in parallel lines. Dr. Deepthi Marathayil proposes a transformative idea: “To build a resilient global economy, climate intelligence must be embedded into every financial decision—just as universally and instinctively as credit checks or risk assessments.” Climate change is no longer an environmental issue; it is a financial stability issue, a community wellbeing issue, and increasingly, a global security issue. And yet, most financial mechanisms still treat climate data as an optional appendix rather than a foundational input. Dr. Marathayil’s idea challenges this status quo. With a Ph.D. in meteorology and deep experience in metocean data science—combined with her role inside one of the UK’s leading financial institutions—she sits at the rare intersection where scientific insight meets financial influence. She has seen first-hand how early warning systems, ocean data, and climate‑risk analytics could prevent trillions in losses… if only they were systematically integrated into how banks, insurers, and governments evaluate risk. Her idea reframes climate science as economic infrastructure, not environmental commentary. She argues that: 1. Data from oceans, atmosphere, and climate systems must become core inputs to lending, insurance, and investment. Her work in metocean and climate‑risk analysis shows how scientifically‑grounded climate intelligence improves resilience for communities and industries alike. 2. Financial institutions hold the leverage to accelerate adaptation—and must shoulder the responsibility. Through her role at TERAOM and her banking experience, she advocates for integrating climate‑risk disclosures and sustainability metrics into daily financial practice to mitigate the risk of change in climate and establish a data-driven adaptation approach for a sustainable economy. 3. Climate‑aware finance can unlock a fairer, more resilient world—especially for coastal and vulnerable communities. Her work at TERAOM supports net‑zero innovation and blue‑economy sustainability. Message - Climate data is not just science—it's financial foresight. If every financial decision included climate intelligence, the world would not only be safer… it would be more equitable. This is the future Dr Marathayil urges us to build: a world where every loan, every investment, every infrastructure project, and every national policy is aligned with the planet’s physics, not in conflict with it.

A journey from the oceans to the financial world — and why the future depends on bringing them together. I grew up fascinated by the natural world (Kerala, India) — by the oceans, the monsoons, and the invisible forces that move our climate. That curiosity eventually became a calling, leading me into oceanography and then a Ph.D. in Meteorology (Reading, UK), where I immersed myself in the science of weather and climate systems. My early research life was spent at the CSIR–National Institute of Oceanography, studying ocean processes and collecting data that revealed how sensitive — and how powerful — our planet’s systems truly are. I learned to read the oceans the way others read financial charts: patterns, cycles, warning signs. But something troubled me. Even as scientists warned of rising risks, the world’s most influential decisions — especially financial ones — were still being made as if the climate crisis were a distant possibility, not a lived reality. So my journey took an unexpected turn. I stepped into the financial world, joining Lloyds Banking Group, where today I serve as a Relationship Manager. Suddenly, I could see the gap from the inside: financial systems were overflowing with data, models, and risk frameworks… but they were missing the most important dataset of all — the climate data I had spent my life working with. In parallel, I continued my scientific and climate‑innovation work at TERAOM as a GeoData & Climate Change Analyst, supporting renewable energy concepts, blue‑economy resilience, and community‑focused climate solution Standing at this intersection — between climate science and finance — I found my purpose. I realised that the world does not suffer from a climate knowledge gap. It suffers from a climate integration gap. And this became the heart of my mission: To make climate intelligence as fundamental to global finance as credit scores, interest rates, or risk assessments. Because climate change is not an environmental problem alone — it is a financial stability problem, a community resilience problem, a human story. Today, my work bridges these worlds: using scientific knowledge to inform financial decisions, supporting communities vulnerable to coastal and climate risks, and advocating for a future where every institution — from banks to businesses to governments — aligns its decisions with the realities of our planet. My TED Story is the story of learning to speak two languages — the language of science and the language of finance — and discovering that our future depends on bringing them together. If we can embed climate intelligence into the world’s financial bloodstream, We won’t just respond to climate change — We will prepare, adapt, and build a fairer world for generations to come.

Translating complex climate and ocean data into simple, human‑focused insights that help people make better decisions. Most people see my work through the lens of banking or scientific research, but few realise how deeply I specialise in analysing metocean and environmental data—skills built through years of research in meteorology and oceanography. Behind the scenes, I’m often decoding patterns from oceans, weather systems, and climate trends so they can be used in practical ways by industries and communities. …connecting climate science to real‑world financial systems. People are often surprised that I can bridge scientific models with financial‑sector realities, helping translate climate risk into meaningful financial insights. It’s a blend of analytical thinking and human understanding that not everyone sees. …bringing calm, clarity, and structure to complex, fast‑moving projects. From managing large teams at Sainsbury’s to coordinating climate‑focused projects at TERAOM, I’ve developed a quiet strength in organising people, processes, and information—even in high‑pressure or uncertain environments. …telling stories—especially the kind that change how people think about climate and resilience. What many don’t know is that I love simplifying scientific ideas into relatable language and narratives, which is why I often engage publicly on topics like climate risk, sustainability, and women’s leadership.
