Affiliate disclosure

Updated 14 November 2026.

Some outbound links can earn a commission. They are marked rel="sponsored nofollow". A commission does not change the climate table or the cited facts.

Amazon

The travel-adapter button is an Amazon search with associate tag thetravelfact-20. If you buy through it, we may earn a commission. It is a search, not a product we tested.

Hotels and tours

The sheet reserves slots for Viator, Expedia, Booking.com, and Travelpayouts. Those program IDs are empty. The slots are labels, not links, and they are not affiliate links until an ID is added and this page says so.

Display ads

Each sheet has an empty slot where a display ad could go later. No ad script is on the site today.
