国际英语新闻:Obama: 'Let's Get to Work' on Climate Change

France says about 2,800 police and soldiers are securing the Le Bourget conference site, and 6,300 others will deploy in Paris. French Interior Minister Bernard Cazeneuve said nearly 1,000 people believed to pose security risks have been denied entry into France.
 
Ahead of the Paris summit, hundreds of thousands of protesters joined worldwide demonstrations Sunday calling for adoption of global environmental control.

Activists linked hands in the heart of the French capital amid tight security, in the wake of the deadly Islamic State terrorist attacks earlier this month that killed 130 people.

Bataclan site visit

Less than an hour after arriving in Paris, President Obama made an unannounced stop outside the Bataclan theater, laying a rose at a makeshift memorial for the 90 people gunned down during a concert on November 13.
 
Later on Monday, during his remarks at the climate summit, Obama said the world stands united in solidarity with the French capital.
 
“We salute people of Paris for insisting this crucial conference go on. An act of defiance that proves nothing will deter us from building the future we want for our children,” Obama said.
