Need To Know.
Border Clash.
The San Ysidro border crossing was closed for hours yesterday after US agents fired tear gas into a group of Central American migrants when a number attempted to break through the border fence separating the US and Mexico. The migrants are part of a larger caravan from Guatemala, Honduras, and El Salvador that arrived in the city of Tijuana, which sits on the Mexican side of the border crossing, directly across from San Diego, earlier this month. The incident occurred after a protest by the migrants calling on the US to speed up the asylum review process devolved into chaos, with a number of protesters reportedly throwing rocks and other objects at border agents. The Mexican government said it was preparing to deport around 500 people who rushed the fence. 

In separate news, President Trump touted a new "Remain in Mexico" policy that would keep migrants seeking asylum on the Mexican side of the border until cases are decided, though the Mexican government denied making a final deal.
Climate Report.
A major report released by the Trump administration on Friday linked the threat of increasingly destructive natural disasters with climate change. The behemoth document, the fourth volume in a congressionally-mandated series that began during the first Bush administration, noted that natural disasters like hurricanes and wildfires have cost the US nearly $400B since 2015 (see full report here). The report - which focused more on quantifying impact than remedies - examined issues ranging from increased flooding in South Carolina, to more frequent heatwaves in the Southern Great Plains, to the effect on military assets around the globe. In moderate scenarios (where average global temperature rise is between 1.1 and 2.6 degrees by the year 2100), the US economy was projected to slow by $280B/year (in 2015 dollars). A separate federal report (paywall) issued Friday said that North America's share of greenhouse gas emissions dropped from 24% in 2004 to about 17% in 2013, mostly due to better vehicle fuel efficiency and the replacement of coal-fired power with natural gas. 

All told, 17 of the 18 hottest years since records began in 1850 have occurred in the 21st century. 
Holiday Shopping Shifts Online.
More post-Thanksgiving shoppers chose to stay home and shop online than ever before, with online sales during last week's Black Friday shopping rush hitting an estimated $6.22B. That total is up 23.6% from last year, and it was the first year to see over $2B in sales made via smartphones. Many consumers didn't wait for Friday - digital sales on Thanksgiving smashed records, passing $3.7B on the day. Preliminary estimates of overall sales data projected a $23B haul for US retailers, also a record, though sales at brick-and-mortar stores fell 4-7%. Sales on Small Business Saturday, during which consumers are encouraged to explore local and independent retailers, topped a reported $3B. Last but not least, today's Cyber Monday is expected to see the highest-grossing single-day online sales in US history, coming in at a projected $7.8B. 

A survey from the National Retail Federation survey said US consumers are expected to spend an average of about $1,000 this season, up 4.1% from last year.
