Scholars implore San Francisco not to cover up the murals that depict misdeeds of George Washington.

It is true that we can't tell the school's students (or anyone else) how to feel. That doesn't mean we must cater to misguided demands that are motivated by those feelings.

Local disasters due to global heating are happening at a rate of roughly once per week.

Mizutori's stance is misguided. We must give priority to long-term reduction of the harm that global heating will do. We must do all we can in that direction. Defending cities from floods and fires of the 2020s must take second place to reducing the floods and fires of the 2030s, 2040s, 2050s and beyond.

It is good to defend cities better in the short term, provided this is not at the expense of measures to reduce the long-term threat.

"[Trudeau's] promise to direct pipeline profits to clean energy is like allowing cigarettes to be sold to kids as long as tobacco companies make generous donations to cancer research."

There is no room in the carbon budget for strip-mining Alberta's tar sands.

Global heating is causing havoc in Somalia, through repeated drought.

Tsipras and Syriza lost the first battle to the global plutocracy. Then, instead of fighting for every inch, they capitulated eagerly.

Then most Greeks did the foolish thing that a defeated people often do: they decided to support a different set of right-wing plutocratists instead. This was pitiful and stupid. Despair can drive a people to do self-mutilation, just as it can drive an individual to it, but don't help your enemies subjugate your people.
