Good Monday morning ... energy and cybersecurity are often intertwined. So I recommend you sign up here for Codebook. Axios' Joe Uchill will bring you the latest in cybersecurity policy and defense news twice a week, beginning tomorrow. 

OK, let's dive in. My latest Harder Line column takes a close look at Exxon's climate-change strategy: its report to investors and a little-noticed session on the topic with analysts earlier this month. And then Ben Geman will take things over for the rest of today’s news.
