The Climate Web Team

support climate web on patreon red backgroundAfter almost 30 years working on climate strategy and climate risk, we have come to realize that climate risk management depends on more targeted communication of climate risks and opportunities. We focus on helping companies address the fundamental “is it worth it?” and “can I do it?” questions of climate change risk management. Through our climate risk scenario building, climate action tipping point services, tour guide services, and using the Climate Web, we can help you navigate a prudent and well-informed course through the uncertainties of climate change and climate risk.

The Climatographers have authored hundreds of publications and reports during their tenure in the climate change field. Contact us at info@climatographer.com for a comprehensive publications list.
