For over 15 years, Degree Day’s team has conducted research on climate and extreme weather impacts. We partner with businesses, engineers, utilities, asset managers, and governments to deliver original, data-driven risk insights. While climate data are central to our work, we integrate diverse information sources and expert judgment. Our hands-on, interdisciplinary approach ensures practical, focused solutions tailored to real-world challenges.
We believe that physical climate risks require expert navigation. Data alone will fail to drive meaningful action, as climate model outputs are inherently limited. That’s why we take a tailored, evidence-based approach, interweaving multiple sources of data, contextual knowledge, and expert judgement to provide organizations with a comprehensive understanding of risk and measurable risk management benefits.
We recognize that organizations face resource constraints. That’s why we are committed to clearly demonstrating the financial value of proactive risk management, ensuring our clients see measurable returns on their investments in weather and climate risk management services.
Principal Scientist
D.J. Rasmussen is the Principal Scientist of Degree Day. He has provided expert guidance and conducted cutting-edge research on the technical, strategic, and policy challenges posed by climate risks for over 15 years.
D.J. has collaborated with Fortune 500 companies, data center operators, federal and state government agencies, utilities, and transit organizations to develop tailored strategies for managing extreme weather and climate-related risks and enhancing resilience.
Previously, he held roles at multinational engineering firms and was a research fellow at Princeton University and NOAA’s Geophysical Fluid Dynamics Laboratory, a pioneering institution in atmosphere-ocean climate modeling.
His expertise is reflected in numerous technical reports and peer-reviewed research published in leading scientific journals, including Science and Nature Climate Change. He received his PhD in Applied Climate Science, Impacts, and Policy from Princeton University.
Marketing and Sales Lead
Daniel Talero leads marketing and sales at Degree Day, shaping the company’s market strategy and leading its engagement with industry professionals that use climate data in their decision-making. Before Degree Day, Daniel worked at KPMG, Guidehouse, and WSP, where he built a specialty in climate risk analytics for global private and public sector clients.
Across these roles, Daniel saw firsthand how mismatches between modeled and observed data stalled projects, misinformed planning, and created avoidable risk. That insight drives his work at Degree Day: giving decision-makers clarity about the data they rely on. Daniel brings both technical grounding and market fluency to help Degree Day's tools reach the teams who need them most.
