Global Model Confirms: Cool Roofs Can Offset Carbon Dioxide Emissions and Mitigate Global Warming

Can light-colored rooftops and roads really curb carbon emissions and combat global climate change?

The idea has been around for years, but now, a new study by researchers at Lawrence Berkeley National Laboratory that is the first to use a global model to study the question has found that implementing cool roofs and cool pavements in cities around the world can not only help cities stay cooler, they can also cool the world, with the potential of canceling the heating effect of up to two years of worldwide carbon dioxide emissions.

You’re standing at the edge of watery abyss. What comes to your mind first? The beauty? The amount of electricity? How unimportant you are? How much money you could make with a visitor center?

How you answer says a lot about how you think, and as pollsters are beginning to wonder, how you might feel about science.

Whether Glaciers Float May Affect Sea-Level Rise

WASHINGTON — Glaciers that detach from the seafloor and begin floating create larger icebergs than glaciers that stay on the sea floor, researchers have found. Floating glaciers also produce icebergs more erratically.

These new observations may help researchers better understand and predict iceberg production from glaciers and ice sheets, improving estimates of sea-level rise due to climate change.

Photo Proof: Super Stars of the Universe Have Humble Beginnings

ANN ARBOR, Mich.—The first close-up picture of a nascent super massive star and its surroundings has shown that the highest mass stars in the universe form just like their smaller counterparts. They are born from swirling disks of gas and dust, rather than from violent stellar collisions.

“How these high mass stars form has been a debate for 20 years,” said Stefan Kraus, a research fellow in the University of Michigan Department of Astronomy who is first author of a paper on the findings published July 15 in Nature.
