Confused about climate change? Talk to our chat bot

BBC News has launched a chat bot to help users learn about climate change in weekly conversations on Facebook Messenger. Subscribers will get an alert every Wednesday inviting them to explore topics from rising temperatures to new ways of tackling global warming. They can also ask questions which the bot will pass on for our human journalists to answer. You can sign up at the bottom of this page. We know that audiences are hungry for a better understanding of where the world stands on targets to control rising temperatures.
