Madison was wrong. Separation of powers, checks and balances, and federalism do not prevent tyranny when a demagogue combines with blind partisanship in Congress and a Judiciary selected by the demagogue.
And John Roberts has never looked like more of a fool.

Many of us are about to be visited by complex weather, possibly including ice storm. Ice can do major damage to trees, even kill them, but an ice-covered tree is hazardous to you. These trees should not be touched. Here are some simple suggestions for managing ice-covered trees.

Packed with frescoes, paintings and reliefs, the federal government’s Cohen Building has been called “the Sistine Chapel of the New Deal.” Advocates fear these works could be at risk.

Important summary of the impact of current geopolitical actions on #climateheritage.
It’s no coincidence the 66 int’l orgs Trump quit cluster around climate and arts & heritage. Trump knows better than most green transformation is a social & cultural issue. It now falls to the rest of us to fill the culture gap in climate policy & action.
