The Eco News Roundup brings stories and commentary about issues related to climate change, renewable energy and the environment.

Denver Becomes Latest City to Require Green Roofs

Denver is the latest city to mandate rooftop gardens or solar installations on new, large buildings, joining San Francisco, New York, Paris, London and other cities around the world with similar green roof measures, the Associated Press reported.

The Colorado capital ranks third in the nation for highest heat island and eighth in the nation for worst ozone/particulate pollution, according to the Denver Green Roof Initiative, a grassroots group that advocated for the city’s green roof ordinance, Initiative 300.

Although the official tally is not in, the ballot initiative had 54 percent approval as of Thursday, signaling that the measure is headed towards victory. The vote will be certified on Nov. 24.

Study Says Public’s Politics Are Correlated With Climate Change Opinion. They Shouldn’t Be.

Ice does not understand the concept of liberal or conservative, it simply melts. Former Oceanographer of the Navy, Admiral David Titley has made this simple but important point when talking about the ridiculous political divide on climate change. Dr. Titley, now a professor at Pennsylvania State University, has a point. I too have been surprised by why many people align their climate change opinions along party lines with very little thought about it. A recent study continues to point to political polarization on climate change.

Melting permafrost is leaving people’s homes on shaky ground

Beneath many parts of Alaska is permafrost, frozen ground that’s stable enough to support buildings. But now the ground is melting and shifting beneath people’s homes.

Some shifting is expected: on top of the permafrost is a layer of soil that freezes and thaws each year. So for a stable foundation, many homes are built on piling, metal rods drilled into the permafrost.

But as the climate warms and the permafrost starts to melt, it can undermine building foundations and cause plumbing problems, uneven floors, and windows that won’t shut properly.

So now engineers must consider a warming climate during construction.

The most extreme effects of climate change people are seeing in the Arctic

nuit elders are reporting a strange sight in the Arctic: The moon and stars appear to be in the wrong place, and the sun is rising in a different location.

Elders believe the earth’s tilt has changed, but western scientists say what they are seeing is an illusion created by a warming atmosphere.

When he was a child, on the shortest day of the year, Dec. 21, he remembers the sun would rise in the south. “You would see it but it would continue to stay red because it was so close to the horizon, and just disappear without ever fully showing up.”
But in recent years, on Dec. 21, the sun rises in the south/southeast and stays in the sky, giving at least six hours of daylight, “and it shows up pretty clearly.”

Longer hours of sunlight, and the sun seemingly rising in a different location, are among the unique visual illusions scientists say are caused by a warming atmosphere.

Scotland ‘on target’ for 100% renewable energy by 2020

Scotland is on target to generate all of its electricity from renewable sources by 2020, the Citizens’ Assembly has heard.
Under chair Ms Justice Mary Laffoy, the 99 assembly members, meeting in Malahide, Co Dublin are spending a second weekend debating on how the State can make Ireland a leader in tackling climate change.

Scotland has hit its 2020 emission targets five years early and has gone from delivering 10 per cent to 60 per cent of its electricity consumption from renewable sources over the past 15 years.

The Zombie Diseases of Climate Change

I visited Greenland because, lately, the land here has gone soft, and disquieting things threaten to wake in it.

Lately, as summers have lengthened and winters have warmed, this seasonal transformation has lost its symmetry. What biologists call the permafrost’s “active layer”—the part of the dirt where microbes and other forms of life can live—now reaches farther underground, and further north, than it has for tens of thousands of years.

The newly active permafrost is packed with old stuff: dead plants, dead animals, mosses buried and reburied by dust and snow. This matter, long protected from decomposition by the cold, is finally rotting, and releasing gases into the atmosphere that could quicken the rate of global warming.

This matter is also full of pathogens: bacteria and viruses long immobilized by the frost. Many of these pathogens may be able to survive a gentle thaw—and if they do, researchers warn, they could reinfect humanity.

At BPI Campus our Progressive Agenda is:
1. People matter more than profits.
2. The earth is our home, not our trash can.
3. We need good government for both #1 and #2.
