A bipartisan group of mayors from across the country has unanimously backed an ambitious commitment for US cities to run entirely on renewable sources such as wind and solar by 2035.
As the US Conference of Mayors wrapped up in Miami Beach on Monday, leaders from more than 250 cities voted on symbolic resolutions pushing back against Donald Trump on climate change and immigration.
Steve Benjamin, the Democratic mayor of Columbia, South Carolina, proposed the resolution with three other mayors. Mayors had been on the frontline of climate and energy issues for a long time, he said, adding that the president’s actions had ignited the excitement of mayors and citizens who want to do more.
The clean energy resolution is one of the many measures that will be sent to Congress and the White House, hoping to influence legislation under an administration that has pulled the US out of the Paris climate accord. It was proposed by Democratic mayors in Republican-dominated states: South Carolina, Texas, Utah and Iowa.
Why Do Bird Eggs Have Different Shapes?
Look to the WingsIn the most comprehensive study of egg shapes to date, scientists say that the best predictor of long or pointy eggs is a bird’s flying ability.

Owls’ are spherical, hummingbirds’ are elliptical and sandpipers’ are pointy.
All bird eggs have the same function — to protect and nourish a growing chick. But they come in a brilliant array of shapes. This variety has puzzled biologists for centuries. Now, in the most comprehensive study of egg shapes to date, published Thursday in Science, a team of scientists seems to have found an answer.
The researchers cataloged the natural variation of egg shapes across 1,400 bird species, created a mathematical model to explain that variation, and then looked for connections between egg shape and many key traits of birds. On a global scale, the authors found, one of the best predictors of egg shape is flight ability, with strong fliers tending to lay long or pointy eggs.
“This paper is remarkable because it creates a wonderfully unified theory for the variety of egg shapes we see in nature,” said Claire Spottiswoode, a bird ecologist at the University of Cambridge and the University of Cape Town who did not participate in the research.
