Most of today's batteries are made up of rare lithium mined from the mountains of South America. If the world depletes this source, then battery production could stagnate.

Sodium is a very cheap and earth-abundant alternative to using lithium-ion batteries that is also known to turn purple and combust if exposed to water—even just water in the air.

Electric Scooters’ Sudden Invasion of American Cities, Explained

           

Turns out there’s a lot of latent demand for a quick and cheap way to get around.

vox.com - by Umair Irfan - August 27, 2018

 . . . Amid the feverish passion for and against scooters, there’s a larger reckoning taking place about rapid changes to our cities and public spaces. The scooters are forcing conversations about who is entitled to use sidewalks, streets, and curbs, and who should pay for their upkeep.

They’re also exposing transit deserts, showing who is and isn’t adequately served by the status quo, and even by newer options like bike share. That people have taken so readily to scooters shows just how much latent demand there is for a quick and cheap way to get around cities.

West Antarctic Ice Melt Poses Unique Threat to U.S.

           

Sea level rise contributions from ice melt in different areas, including Greenland (a), West Antarctica (b), East Antarctica (c) and median of global glaciers (d). Values are ratios of regional sea level change to global mean sea level change. Adapted from Kopp et al. 2015.

News of Antarctica's accelerating ice melt garnered worldwide headlines yesterday, as scientists revealed that 3 trillion tons of ice has been lost to the sea since 1992 — mostly from the thawing West Antarctic Ice Sheet and Antarctic Peninsula.

Why it matters: The location of the ice melt is important for determining the future of coastal communities, according to climate scientists. And, due to West Antarctica melting, it turns out that the U.S. coastline will be hit extra hard . . .

Hurricanes Are Strengthening Faster Than They Did 30 Years Ago

                   

A new study found that hurricanes intensify more quickly now than they did 30 years ago. Hurricanes from 2017 like Irma (center), and Jose (right) are examples of these types of hurricanes. Hurricane Katia is seen on the left.  (Photo: NOAA)

With the start of hurricane season just three weeks away — and memory of last year's disastrous storms still fresh — scientists reported that powerful hurricanes are strengthening faster than they did 30 years ago.

Four of the monster hurricanes last year (Harvey, Irma, Jose and Maria) all intensified rapidly — when the maximum wind speed increases at least 29 mph within 24 hours . . .

 . . . According to a study out this week, the main cause appears to be a natural climate phenomenon that warms the seawater where hurricanes typically intensify in the Atlantic.

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.

Are We Ready for the Deadly Heat Waves of the Future?

           

HEAT ISLANDS  Heat claims more lives than floods, hurricanes and other weather-related disasters. How will cities cope as temperatures rise?  ULTRAFORMA/ISTOCKPHOTO

When days and nights get too hot, city dwellers are the first to run into trouble

sciencenews.org - by AIMEE CUNNINGHAM - April 3, 2018

Since 1986, the first year the National Weather Service reported data on heat-related deaths, more people in the United States have died from heat (3,979) than from any other weather-related disaster — more than floods (2,599), tornadoes (2,116) or hurricanes (1,391). Heat’s victim counts would be even higher, but unless the deceased are found with a fatal body temperature or in a hot room, the fact that heat might have been the cause is often left off of the death certificate, says Jonathan Patz, director of the Global Health Institute at the University of Wisconsin–Madison.

As greenhouse gases accumulate in the atmosphere, heat’s toll is expected to rise. Temperatures will probably keep smashing records as carbon dioxide, methane and other gases continue warming the planet. Heat waves (unusually hot weather lasting two or more days) will probably be longer, hotter and more frequent in the future.

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.

Wildfires Hit Greenland After Record Temperatures

           

This satellite photograph depicts the wildfire raging in Greenland, as seen from space last week. - NASA Earth Observatory

phys.org - August 14, 2017

Police in Greenland warned people to stay away from western areas of the island as wildfires scorched swathes of scrubland . . . 

 . . . Denmark's meteorological service BMI said the island registered its hottest-ever temperature of 24.8 degrees (77 Fahrenheit) on August 10.

Last year was Greenland's hottest on record.

The Danish territory has lost about 4,000 gigatons of ice since 1995, British researchers said in June, making ice melt on the huge island the biggest single contributor to rising sea levels.

renewableenergylongisland.org - June 19, 2016

On June 15, 2016 Renewable Energy Long Island, along with a number of cosponsors, organized the South Fork Clean Energy Forum, to discuss with community leaders how to build a smarter, more affordable, more resilient energy system for the South Fork of Long Island. At the forum, experts presented exciting new plans to make the South Fork a leader in clean energy.

The South Fork Clean Energy Forum was the first time the public was able to get an in-depth look at the various building blocks and proposals for a new energy system for the South Fork. It was also the first energy forum ever co-sponsored by both towns, and the first one to be broadcast in both towns.
