Increase in dust in the air, since 1800, may have cancelled out some of global heating.

Up to 8% of it.

However, since the 1980s, the amount of dust has been decreasing.

On the complex relationship between unions and public opinion.

In the long term, unions need public support to block right-wing governments from legislating to impede organizing and striking. People will give this support through the occasional inconvenient strike if they recognize that in the long term it makes a better life for all the non-rich. Thus, unions must make sure that the labor movement keeps that aim in mind.

Peruvian thugs raided San Marcos University and forced students out of their dorm at gunpoint and with violence. The thugs gave them no explanation, and reportedly then began to search the students' rooms.

Some years ago, San Marcos University had a student group, San Marcux, which taught students how to spread the free software ideas. They invited me to speak on some occasions. That was years ago. I wonder what is happening there now.

When companies are compelled to reduce staff, some countries laws' pressure the companies to do it in a gradual way that doesn't cause a trauma to workers, rather than using the mass layoffs typical in the US.

A general discussion of the moral issues of which kinds of protest are legitimate, then applied to the case of protesting by blocking highways.

This discussion makes sense, in its narrow framework. However, treating the Just Stop Oil protests in isolation, ignoring the deadly threat they confront, leads to wrong conclusions.

Global heating and the resulting climate breakdown are already causing millions of deaths. This year, 200 million deaths are predicted. The UK government has pledged to help stop global heating but is not taking much action. Can you seriously argue that blocking highways in desperation to pressure the state to carry out its mission is morally wrong?

Blocking highways seems to be a self-defeating method, but that is a different kind of issue.
