Need To Know.
Shutdown Ends (For Now).
The longest federal government shutdown in US history ended late Friday evening after President Trump and congressional leaders agreed to a short-term funding bill. Talks to end the 35-day-long stalemate quickly accelerated after a shortage in air traffic controllers and supporting staff caused major delays at airports around the US, including a ground halt at New York's La Guardia airport. The plan, which funds operations through February 15th, provides time for continued talks on border security - a White House request for $5.7B to expand a border wall at the center of the standoff was not funded in the short-term bill. The deal included back pay for the nearly 800,000 federal workers affected by the shutdown, many of whom missed their second consecutive paycheck on Friday. 
Brazil Dam Collapse.
At least 58 people are dead and nearly 300 missing after a dam at an iron ore mining site collapsed in southeast Brazil. The dam was owned by Vale, a multinational metals and mining company and the world's largest producer of iron ore and nickel. Unlike typical dams built for water management, the failed structure was a tailings dam, which is meant to hold sludge-like mixtures of mining byproducts. A number of such dams are among the largest engineered structures in the world. Vale was also involved in a 2015 dam collapse in the same region that killed 19 and resulted in one of the worst environmental disasters in Brazil's history. The break, which released an estimated 12 million cubic meters of waste, is newly-elected President Jair Bolsonaro's first crisis

Polar Vortex.
The temperature in International Falls, MN, hit 49 degrees F below zero on Sunday, passing the day's record of 36 degrees F below zero as a deep freeze set in across the upper Midwest. The frigid conditions will continue throughout the week from Minneapolis to Detroit while moving towards the East Coast on Tuesday. The cold air is driven by changes to what is known as the polar vortex - a pocket of low-pressure, cold air that rotates counter-clockwise above both of the Earth's polar regions (see 101). When the air masses have strong rotation, the cold tends to sit near the poles. When the rotation weakens, the cold air masses can be dislodged by pockets of warmer air, pushing an arctic blast southward. 

The chill is expected to last at least through the end of the week.
