Climate change means more floods, which overwhelm urban sewers and send raw sewage into rivers and streams. Philadelphia is aiming to capture rainwater before it flows into city drains.

THE NOVEL coronavirus has halted much of the country — but it has not stopped the Trump administration from ramming through unwarranted and unwise rollbacks of major environmental rules. Administration officials have pressed government workers, even amid the pandemic, to rip up regulations well before the November election, which would make them harder for a new president to reinstate.

Here is the stark and sad truth: There is almost no way to explore the planet without harming it.

A company called Oceanix is building a prototype floating island as an experimental solution for crowded coastal cities threatened by climate change, the company told the United Nations habitat program Wednesday.

Unlike “seasteading,” Silicon Valley’s vision of independent city-states that float outside national rule, the islands proposed by Oceanix would follow local laws. Nor would these be playgrounds for the rich, Collins Chen said. He told The Washington Post he was “not ready to share” projected costs. But he staked his claims of affordability on the cheapness of prefabrication and marine development. Construction costs would stay low, he said, because the floating hexagons can be mass-produced in factories and towed to destination bays.

Trees are the most efficient carbon-capture machines on the planet. Through photosynthesis, they absorb carbon dioxide, the greenhouse gas that traps heat in the environment, and turn it into energy. That energy creates new leaves, longer stems and more mass — locking away carbon.
