DISASTERSWhy Are So Many Historically Rare Storms Hitting the Carolinas? Geography Puts These States at Risk, and Climate Change Is Loading the Dice
Why have so many storms that, historically and statistically, should be exceedingly rare, struck the Carolinas in just a few years? In regions near the coasts, the frequency of heavy rainfall has increased as a result of human-caused climate change. Warmer air can hold more moisture, and warmer oceans provide that moisture as the fuel for heavy rainfall.

FLOOD PLAINSThe U.S. Is Finally Curbing Floodplain Development, New Research Shows
Over the past century, the United States has built millions of homes along coastlines and rivers, developing on land that is all but destined to flood. At the same time that the warming of the planet has raised sea levels and increased rainfall, annual flood damages have surged in recent decades in large part because more homes are in flood-prone areas now than ever before.

ISRAEL’S PAGER ATTACKPagers and Walkie-talkies Over Cellphones – a Security Expert Explains Why Hezbollah Went Low-Tech for Communications
In general, I believe the adversary in an asymmetric conflict using low-tech techniques, tactics and technology will almost always be able to operate successfully against a more powerful and well-funded opponent. But from a cybersecurity perspective, Israel’s attack on Hezbollah’s pagers shows that any device in your life can be tampered with by an adversary at points along the supply chain – long before you even receive it.
