Obama's Climate Speech and Africa Trip: Connection?

Obama's big climate speech yesterday and his Africa trip today. Any connection? I posed the question (via Twitter) at yesterday's USGLC conference.

US Trade Representative Michael Froman didn't have time for questions, but moderator Frank Sesno asked Jack Lew later in the program. Here's Lew's answer:

In short, Lew said Obama's speech referenced the international component of climate change and that Africa will increasingly need clean power sources. He called climate the "formative issue of our day" and said the United States should use bilateral and multilateral assistance to help developing countries continue to grow their economies while boosting sustainable and affordable power.

What do you think of the response?
