Governments around the world have agreed to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit). That would require an 80 percent reduction in energy sources like coal, oil and natural gas, which emit carbon dioxide into the air.
Nations are far from that ambitious path. There are big political and economic challenges. But technologists do see a way — at least for the United States — to achieve that goal.
The World Health Organization has declared a polio emergency in Syria.
After being free of the crippling disease for more than a decade, Syria recorded 10 confirmed cases of polio in October. Now the outbreak has grown to 17 confirmed cases, the WHO said last week. And the virus has spread to four cities, including a war-torn suburb near the capital of Damascus.

Some Oregon officials were sounding alarms about the tech company's work on the state's online health care exchange as early as last spring. Oracle was behind schedule and, worse, didn't seem able to offer an estimate of what it would take to get the state's online exchange up and running.
