Most states, and the US overall, are weak in resisting Covid-19 because they don't have enough testing capacity.

In California the shortage is disastrous.

It is easy to have enough testing capacity if you keep the number of cases down. But once it gets away from you, you have to run fast to catch up.

I've read that the US overall needs three times as much testing capacity as it has now. But try getting a Republican to understand that.

Erosion by waves, surely boosted by sea level rise, is eating away at rich people's homes in Australia.

To force people to leave home with two hours' notice seems heartbreakingly cruel. Even rich people, who could afford to buy a replacement for everything, will lose things that are impossible to replace.

If people want to take action to prevent seas from claiming the homes of tens of millions of people, mostly not rich, they should demand a rapid reduction in emissions of greenhouse gases.

A Philadelphia thug faces charges for pepper-spraying protesters.

Copyright absurdity: In Japan, retweeting a photo is copyright infringement — because of technical details of how Twitter presents the photo. Twitter has been forced to identify the people who did the retweeting.

In the US, this would typically be fair use, but that defense does not exist in other countries.

The UN concept of "responsibility to protect" arguably applies when a government gratuitously leaves the population open to a sometimes-fatal epidemic, as the US government is doing now.
