Bill Gates interview: The breakthrough technologies that will solve climate change

• Bill Gates says curbing climate change is more challenging than putting an end to the coronavirus pandemic, and requires urgent action. 
• In a new book set to publish this month, he lays out how to clean up the worst-emitting sectors.
• Insider interviewed Gates last month. Read on for our full conversation with the Microsoft billionaire.  

In 2015, Bill Gates warned in a speech that we weren’t ready for the next pandemic, and he urged action.

An infectious virus is “the greatest risk of global catastrophe,” he said. “We’ve actually invested very little in a system to stop an epidemic. Time is not on our side.”

The consequences of inaction then are playing out today: The coronavirus has infected more than 100 million people worldwide and killed more than 2.3 million.
