New York, NY — The July/August issue of Popular Science is on newsstands and the iPad now.

We Can’t Stop Breaking Heat Records 2016 was our planet’s hottest year since humans began keeping records, with average global surface temperatures spiking to 58.69 degrees Fahrenheit—1.69 degrees warmer than the 20th-century average. It might not sound like a lot, but the difference between our current global average and one during an ancient ice age is only 5 degrees or so. And human fingerprints are all over the recent temperature trends (page 8). 

Embrace Your Inner Prepper For most of us, an elaborate doomsday bunker is overkill. But when facing down whatever Mother Nature flings at you, a little preparation can save you from that last-minute grocery store panic. Start with water, batteries, and the infinitely versatile duct tape. Then branch out into meal supply kits and multi-tools. (page 32).

The Last Umbrella You’ll Ever Need A corner-store umbrella might save you in a pinch, but it’s bound to fail at an inopportune moment. It’s worth it to invest in a canopy tough enough to deserve a lifetime warranty. If any of these rain blockers do flounder, you can replace them for free—instead of angrily stuffing them in a trash can (page 34).

Mod Squad With drought parching the West, seeding clouds is a more appealing option than ever. Cloud seeding is when a crew of scientists and researchers drop silver iodide into the clouds and watch to see if they are making extra snow. Could the SNOWIE team (Seeded and Natural Orographic Wintertime clouds: the Idaho Experiment) prove it actually works? (page 42).

Exposed Humans aren’t the only ones battling the forces of nature. PopSci has identified eight other creatures living on the brink—thanks to extreme weather and climate change. The harlequin frog, giant panda, snow leopard, koala, woodland caribou, whooping crane, chevron butterflyfish, and Adélie penguin’s populations are all at risk (70).

Tales From the Field Chase a massive storm with a Weather Network meteorologist; raft a volcanic-ash field in Katmai with a National Park Service Ranger; rescue a family from a Louisiana flood with a U.S. Coast Guard Aviation Maintenance Technician, and more (page 81).

Everything-Proof Your House The environment can, at any time, put your home under siege—whether it’s tornadoes sweeping through the Midwest, hurricanes inundating the coasts, wildfires burning up the Southwest, or blizzards freezing the North. But with clever architecture and advanced materials, houses can defend themselves. Consider some of these designs when preparing to batten down the hatch (page 56).
