New topographic and predictive rainfall data means more people in Harris County will be mapped in floodplains.

houstonpublicmedia.org - by Davis Land - November 26, 2018

When Hurricane Harvey left so much of Houston underwater, it highlighted a problem that’s been getting worse for years: Harris County’s existing floodplain maps just don’t work.

In the year since the historic storm, flood control officials have promised to change that, and they already had plans to redo the maps, but new data on the geography of the area and the amount of rainfall forecasters expect in the future means the new maps could look drastically different.

It’s crucial the maps are done right, as people are using the maps, meant to set flood insurance premiums, for more than they are intended . . .

 . . . One Concern is launching a machine learning platform that provides cities with specialized maps to help emergency crews decide where to focus their efforts in a flood. The maps update in real-time based on data about where water is flowing to estimate where people need help the most. It’s the latest in a wave of AI-powered tools aimed at helping cities prepare for an era of severe, and increasingly frequent, disasters.

Hurricane Harvey swamped Houston with seven days of pounding rain last August. When scientists went back to look at historical weather patterns, they reported Harvey dumped 20 percent more rain than it typically would have. The culprit: climate change.

The flood maps don’t factor in sea level rise or changes in extreme weather, and many are years out of date. In Mexico Beach, 'minimal-risk' homes were swept away.

insideclimatenews.org - by James Bruggers - November 1, 2018

The official map laid it out for more than 200 homes within the community of Mexico Beach, Florida: the federal government had characterized their flooding risks as minimal, despite their near-beachfront locations.

That meant for them there were no requirements to buy flood insurance, and local residents say many did not.

When Hurricane Michael and its 155-mile-per-hour winds slammed into the town on Oct. 10, with a storm surge of perhaps 19 feet, the result was devastation. An analysis by coastal geologists from Western Carolina University has found that 70 percent of the homes were demolished. Another 10 percent were severely damaged.

FBI searches Florida mail center in hunt for sender of package bombs | Reuters

Authorities found two more suspicious packages on Friday addressed to U.S. Senator Cory Booker and James Clapper, the former U.S. director of national intelligence, amid a manhunt for the person who sent bombs to prominent Democrats and critics of U.S. President Donald Trump . . .

 . . . Meanwhile, a local police bomb squad and canine units joined federal investigators on Thursday to examine a sprawling U.S. mail distribution center at Opa-Locka, northwest of Miami, Miami-Dade County police said.

U.S. Homeland Security Secretary Kirstjen Nielsen said that Florida appeared to be the starting point for at least some of the bomb shipments.

Urgent changes needed to cut risk of extreme heat, drought, floods and poverty, says IPCC

the guardian.com - by Jonathan Watts - October 8, 2018

The world’s leading climate scientists have warned there is only a dozen years for global warming to be kept to a maximum of 1.5C, beyond which even half a degree will significantly worsen the risks of drought, floods, extreme heat and poverty for hundreds of millions of people.

The authors of the landmark report by the UN Intergovernmental Panel on Climate Change (IPCC) released on Monday say urgent and unprecedented changes are needed to reach the target, which they say is affordable and feasible although it lies at the most ambitious end of the Paris agreement pledge to keep temperatures between 1.5C and 2C.

These are the typical areas for development and tracks of Atlantic Basin tropical cyclones in October.

At a Glance

Florida is the state most likely to see a landfalling hurricane in October.

Since 1950, 15 hurricanes have made a U.S. landfall in October, eight of which occurred in Florida.

In South Florida, October is the month with the most hurricane direct hits.

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 do you get healthy food on the table when you can't find any?

This is a question that Ortilia Lujan Flores had grappled with many times before.

She wanted affordable, nutritious food, but lived in a neighborhood that didn’t have an accessible grocery store.

Flores couldn't drive, which limited the few food options she had. "There was nowhere to go," she explains.

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.

Solar installers could make a better business case for panels bundled with heat pumps and other electric devices that offset natural-gas use, according to the Rocky Mountain Institute.

Solar installers could offer rooftop customers even more savings by bundling solar panels with heat pumps and other electric appliances, according to a recent study by the Rocky Mountain Institute.

RMI studied the carbon benefits and financial costs  of electrification of home heating in four U.S. cities. The carbon reductions were pronounced in three of the four. The financial costs were harder to overcome—unless the electricity comes not from the grid, but from the rooftop.
