After a historic Atlantic storm season, climate change monitoring has become more important than ever before as have the forecasting of the effects on sea level change and what this means for global populations and ecosystems. Although there are plenty of challenges facing scientists, governments and businesses when it comes to climate, it’s not all bad news. Huge leaps forward have been made in fossil fuel disinvestment, green tech innovation continues at a frantic pace and changes in Chinese energy policy has seen renewable investment on a whole new scale.

Submit an enquiry with your audience, date and outcome. A consultant will return with fees, availability and a shortlist of Climate speakers aligned to your brief. ### What are typical speaking fees for Climate speakers? Fees depend on the speaker, format (in-person or virtual), location, session length and required customisation. Contact London Speaker Bureau for a tailored quote — we do not publish a public rate card. ### Can you shortlist Climate speakers against our brief? Yes. Share your audience, sector and objective and London Speaker Bureau will recommend the right voices from our Climate network (148 profiles listed here) — including speakers not listed on this page. ### Are Climate speakers available for international events?

We brief the speaker on your audience profile, sector and objectives so the talk is shaped to your event. The level of customisation depends on the speaker and lead time. ### Do you only book keynotes, or also workshops and panels?
