The world's second-largest Ebola outbreak on record is underway in the Democratic Republic of the Congo and has now spread to Uganda.

What to watch: The World Health Organization and aid groups are pouring resources into the region to try to contain it, but the longer this Ebola outbreak continues, the greater the likelihood it will spread to other highly populated areas within the country, move to other neighboring countries or even internationally.

Threat level: The danger of this particular outbreak, which began Aug. 1, 2018, is that it's what several experts call the "perfect storm" of a highly lethal and contagious virus in an area of the DRC that's a hub for poverty and neglect, insurgent activities, distrust of government and international organizations, and a mobile population with many refugees.

The big picture: The world is being buffeted by rapid yet uneven advances in technology that will revamp work and what it means to be human. At the same time, fundamental demographic changes will alter democracies and autocracies alike while the effects of climate change accumulate, physically redrawing our globe.
