About XClimate – Climate Health Intelligence from Dartmouth

Building climate health intelligence
for everyone.

XClimate was founded at Dartmouth College to help people understand how their environment affects their health — and what to do about it.

Our story

XClimate started with a question: why do some days feel harder than others, even when nothing in your life has changed? The answer, it turns out, is often in the air.

Research shows that air quality, UV exposure, barometric pressure, and temperature shifts have measurable effects on mood, energy, and cognitive function. But no one was making this personal. Weather apps tell you the temperature. Health apps track your steps. Nothing connected the two.

XClimate bridges that gap. We built an AI-powered platform that correlates real-time environmental data with your personal health signals to surface patterns you'd never notice on your own — and deliver actionable recommendations to help you feel better.

Our mission

To make climate health intelligence accessible to everyone. We believe that understanding the connection between your environment and your wellbeing is not a luxury — it's a basic health need that's been overlooked.

Climate affects everyone. But it doesn't affect everyone equally. XClimate is designed to be accessible, affordable, and useful for people who are most affected by environmental conditions — not just those with the resources to monitor them.

What we believe

Mood is data

How you feel is a valid health signal. We treat it as seriously as heart rate or blood pressure.

Privacy is non-negotiable

We never sell your data. We never train AI models on your private health information. Full stop.

Science drives everything

Every insight we deliver is grounded in peer-reviewed climate science and behavioral health research.

Access over exclusivity

Climate health tools shouldn't require a wearable, an app, or a premium subscription. Text works.
