Imagine if scientists could figure out how Earth's climate has varied for hundreds of millions of years, build sophisticated computers to project how humans are now radically altering it, and warn the public, only to have greedy corporations & venal politicians ignore them. Criminal. Immoral. Evil.

Imagine scientists could invent an effective, safe, cheap way to prevent a wide range of terrible diseases and the people in charge of the nation's health system worked hard to stop people from using them.
That would be crazy. Criminal. Immoral. Inexcusable.

The share of counties where 95% or more of kindergartners were vaccinated against measles has dropped from 50% before the pandemic to 28%, according to our analysis of public records from 44 states and the District of Columbia. At least 19,000 schools are now more vulnerable to outbreaks.

Especially if the first season is only 8 episodes or so.

Let me be explicit. If you hear anyone say replacing fossil fuels with renewables is going to be expensive, they're either misinformed, uninformed, or lying to you.
Even leaving out the massive economic costs of #climate changes caused by burning fossil fuels, #renewables are cheaper now.
