On the COVID-19 front, the projections for the end of this month are "up to 435,000," according to what I read yesterday.
That's based on 365k deaths through today.
But it's also based on a model that has the number of daily deaths plummeting starting on January 12th, even without rapid rollout of the virus. We've just hit new highs for deaths the last two days. We'll not set new daily death records all of the next 4 days, but we might set new records for those days of the week - we had a new average daily death rate that is hundreds above the projections from most places.
So, ~430k for the end of this month and ~567k (up to 600k) by April 1 strikes me as hopelessly naïve unless they have a reason for expecting the death rate to plummet that doesn't show in their model. 640k by April 1 seems conservative, and closer to 690k more likely.
