What will happen once Britain officially leaves the European Union? Could there ever be a second Brexit referendum? How are cities around the world trying to deal with the repercussions of climate change? And how will the results of the upcoming midterm elections shape U.S. relations with the rest of the world?

For more than a year, I’ve been discussing the future of Europe with readers on WhatsApp. Over the coming months, we’re inviting you to join the second round of our project, as we embark on a series of month-long journeys that will explore the issues that matter most to readers in Europe and elsewhere, including migration, populism and climate change.

Subscribe here to be part of these conversations. I also intend to share relevant articles, run occasional polls and talk directly with you in individual chats.

In October, we’ll take a closer look at populism. November will be all about a changing role of the United States in the world, as voters head to the polls. In December, migration is set to be our focal point, and in January, I’ll take you along with me to Australia to discuss climate change and what we can do to prevent the worst repercussions.
