12 scary takeaways from the climate report the Trump administration dropped on Black Friday - and one reason for hope

On Black Friday, as many Americans were shopping or spending time with family, the Trump administration published a major report on climate change.

The findings are dire.

Average temperatures could rise by up to 11 degrees Fahrenheit by the end of the century in a worst-case scenario. We could see as much as 6 feet of sea-level rise. And the price tag associated with deaths from extreme temperatures could reach $140 billion if we continue business-as-usual.

The study, called the "National Climate Assessment," is the fourth in an ongoing series mandated by a 1990 law. It looks at how climate change is affecting the US now and what the country might look like by the end of the century. Hundreds of scientists and other experts from academia, government, nonprofits, and the private sector help write and review it, a process that takes years.

Thanks to advances in climate science, this latest version gets specific about how various regions of the US will be impacted differently, which economic sectors will take the hardest hit, and how healthcare costs will rise as diseases spread and air quality worsens.

Here are the most important and scary takeaways from the report.
