As the inevitable primary battles heat up, Sen. Bernie Sanders (I-Vt.) took the opportunity on Friday to slam former Vice President Joe Biden's "middle ground" climate change plan that has been crafted with the help of a former aide to President Obama.

Why it matters: Climate change has become one of the most pressing issues as Democratic presidential candidates claw their way to the party's 2020 nomination.

What they're saying: Rep. Alexandria Ocasio-Cortez also berated Biden for his moderate proposal tweeting, calling it "a dealbreaker. There is no “middle ground” w/ climate denial & delay. Blaming 'blue collar' Americans as the main opponents to bold climate policy is gas lobbyist 101. We’re not going to solve the climate crisis w/ this lack of leadership. Our kids’ lives are at stake." Ocasio-Cortez introduced the progressive Green New Deal that other presidential candidates have come out in support of.

This week, United Airlines warned 36,000 U.S. employees their jobs were at risk, Walgreens cut more than 4,000 jobs, Wells Fargo announced it was preparing thousands of terminations this year, and Levi's axed 700 jobs due to falling sales.

Why it matters: We have entered round two of the jobs apocalypse. Those announcements followed similar ones from the Hilton, Hyatt, Marriott and Choice hotels, which all have announced thousands of job cuts, and the bankruptcies of more major U.S. companies like 24 Hour Fitness, Brooks Brothers and Chuck E. Cheese in recent days.
