Most U.S. Companies Say They are Planning to Transition to a Circular Economy

But the definition of circular economy remains unhelpfully broad.

fastcompany.com - by Adele Peters - February 5, 2019

When Amsterdam’s Schiphol Airport remodeled a terminal, it didn’t buy light bulbs; instead, the company signed a contract for “light as a service” from Signify, the company formerly known as Philips Lighting. Signify owns the physical lights, giving it the incentive to make products that last as long as possible and that can be easily repaired and recycled if anything breaks.

The service is one example of a shift to a circular economy model. Rather than just mining materials and manufacturing products that ultimately end up in landfills, companies are increasingly trying to figure out how to use resources in closed loops.

Unusually Warm Sea Water Boosted 2017's Catastrophic Hurricane Season

                   

A Sept. 7, 2017, satellite image from NOAA shows the eye of Hurricane Irma, left, just north of the island of Hispaniola, with Hurricane Jose, right, in the Atlantic Ocean. Six major hurricanes formed in the Atlantic in 2017, including Harvey, Irma and Maria.  (Photo: AP)

usatoday.com - by Doyle Rice - September 27, 2018

The catastrophic 2017 hurricane season – which included such monsters as Harvey, Irma and Maria – was fueled in part by unusually warm ocean water, a new study suggests.

And because of human-caused global warming, the study said similar favorable conditions for fierce hurricanes will be present in the years and decades to come . . .

 . . . "We show that the increase in 2017 major hurricanes was not primarily caused by La Niña conditions in the Pacific Ocean, but mainly by pronounced warm sea surface conditions in the tropical North Atlantic," the study said.

Solar energy is becoming more and more popular as prices drop, yet a home powered by the Sun isn’t free from the grid because solar panels don’t store energy for later. Now, researchers have refined a device that can both harvest and store solar energy, and they hope it will one day bring electricity to rural and underdeveloped areas.

The problem of energy storage has led to many creative solutions, like giant batteries. For a paper published today in the journal Chem, scientists trying to improve the solar cells themselves developed an integrated battery that works in three different ways.

How Storms, Missteps and an Ailing Grid Left Puerto Rico in the Dark

           

A transmission tower and downed lines in the mountainous terrain of eastern Puerto Rico. Workers from the island and throughout the United States have worked to restore power after Hurricanes Irma and Maria last September.

It took months to restore electricity in Puerto Rico after hurricanes dealt a one-two punch. Many homes are still without power, and the system’s future is far from certain.

 . . . After Maria and the hurricane that preceded it, called Irma, Puerto Rico all but slipped from the modern era . . .

 . . . an examination of the power grid’s reconstruction — based on a review of hundreds of documents and interviews with dozens of public officials, utility experts and citizens across the island — shows how a series of decisions by federal and Puerto Rican authorities together sent the effort reeling on a course that would take months to correct. The human and economic damage wrought by all that time without power may be irreparable.

Tired of Waiting for Electricity in Puerto Rico, Man Builds His Own Solar Power System

           

Frank says his experience with electrical work helped him tackle the solar panel installation.

Another day, another blackout in Puerto Rico; Wednesday's blackout was the latest to hit the island still recovering from Hurricane Maria. But one man beat the power outages and his troublesome gas generator by switching to solar power.

"As I'm typing this, we are in the middle of a blackout and my fridge, lights and fans are running worry free," a man named Frank told CNN.

cnn.com - by Nicole Chavez - April 6, 2018

Puerto Rico is closing 283 schools this summer following a sharp drop in enrollment in the past year, officials said.

Since May, schools have lost 38,762 students as the US territory works to rebuild following a devastating hurricane last year, the education department said in a statement.

"Half of the existing schools are at 60% of their capacity," it said. The department said only 828 schools will reopen in August.

Scalable Water Management Solutions for Developed & Developing Cities

           

Cape Town, South Africa

meetingoftheminds.org - by Manohar Patole - April 3, 2018

The growth of urban settlements is subject to a range of factors influenced by demographic, economic, political, environmental, cultural, and social factors. Weather variability, or climate change, has recently risen up this list. These two factors: climate change and urban population growth, are dramatically affecting urban water management. On one hand, growing populations increase urban water demand and on the other, climate change has increased water variability (volume, distribution, timing and quality) . . . 

 . . . How will cities adapt? Reframe. Develop new responses.

Pregnancy Outcomes after ZIKV Infection in French Territories in the Americas

submitted by Anita Goel

                                                     

N Engl J Med 2018; 378:985-994
DOI: 10.1056/NEJMoa1709481

Abstract

BACKGROUND

The risk of congenital neurologic defects related to Zika virus (ZIKV) infection has ranged from 6 to 42% in various reports. The aim of this study was to estimate this risk among pregnant women with symptomatic ZIKV infection in French territories in the Americas.

METHODS

From March 2016 through November 2016, we enrolled in this prospective cohort study pregnant women with symptomatic ZIKV infection that was confirmed by polymerase-chain-reaction (PCR) assay. The analysis included all data collected up to April 27, 2017, the date of the last delivery in the cohort.
