Why and how we built this

The Washington Post has been publishing coverage of the climate and environment for more than two decades. We know that readers may have questions that aren't always easy to answer.

This tool searches the past eight years of our articles and ranks the results based on relevancy. We then use a Large Language Model to write a response to match the query you have posed. This experiment may not always understand your question or be able to come up with an answer. Read our FAQ to learn more and visit our feedback form to tell us about your experience.
