4:20 PM | Has the Sun Blown its Top?
I spotted this image on the Facebook page for NASA’s Solar Dynamics Observatory and found it so compelling that I had to share it. The brilliant arcing loops of hot plasma, and the roiling bright areas certainly caught my attention. But I was most intrigued by the two bluish, dark regions, especially the one atop […]The post Has the Sun Blown its Top? appeared first on ImaGeo.

12:03 PM | Mintylicious
This isn’t a fantasy alien landscape, its an image of a mint leaf, taken with a scanning electron microscope by Annie Cavanagh. This low-res version is available from Wellcome Images with a Creative Commons license, which allows me to show you how awesome plants are. The spike is a trichome (a hair, essentially). The blobs are oil, sitting on oil glands, and are what gives mint is delicious flavour. The oval structures that look a bit like seeds scattered on the surface, are stomata, […]

8:07 PM | When Pigeons Break the Pact
Birds lead hazardous lives. They are preyed on by cats. They fly into tall buildings, glass windows, airplanes, cell towers, and wind turbines. All of this happens mostly out of our sight. In New York City, where I live, people go about their business while pigeons flutter all around us, sometimes annoyingly, but largely ignored. One of the […]The post When Pigeons Break the Pact appeared first on Collide-a-Scape.

6:59 PM | Lake Mead Shrivels to Historic Low Level. In Just Two Years, the Change is Dramatic Enough to be Visible from Space
Not that it was any surprise, but thanks to continuing drought, Arizona’s Lake Mead is projected to shrivel this week to its lowest level since it first filled behind Hoover Dam in the 1930s. All told, 40 million people in seven states depend on water from the Colorado River Basin. Lake Mead is the giant […]The post Lake Mead Shrivels to Historic Low Level.

6:17 PM | So did Lake Mead break the record yet or not?
At this point it’s just a parlor game, but has Lake Mead broken through the old “lowest since they filled it” record yet or not? Regardless of the fractions of an inch involved, it’s a big deal. (Go to Circle of Blue for an explanation.) But the conversation this week has been a bit confused ...Continue reading ‘So did Lake Mead break the record yet or not?’ »

4:09 PM | Weekend Reads: Skunk Baby Boom, Farming Without Water, In Plankton We Trust
By Jason Bittel The Next BreadbasketCould the fields of Sub-Saharan Africa feed the world? Foreign investors think so, and the land grab is already on. But according to Joel K. Bourne, Jr., bringing a green revolution to Africa is a double-edged spade for the people who live there. For some, sustainable agriculture means new technology and more food. For others, it means surrendering family farms and working under deplorable conditions. National […]

Smart words from Phil Isenberg, California’s water sage: [O]ur historic population and economic growth—and the social and individual choices we have made—explain the water and environmental problems we face today. Unless we acknowledge that water supplies are limited, and act to temper our water use, we will limp toward the next drought, and act surprised when ...Continue reading ‘Isenberg: Drought amplifies, not causes, water problems’ »

By Jason Bittel Cruel summer: The same fluctuation of the jet stream that caused multiple polar vortices this winter will give the Midwest and East Coast a blast of cooler-than-normal air next week—which ironically will bring a lot of hot air from the mouths of certain conservative radio hosts. Remember everyone, a few cold snaps (no matter the time of year) don’t mean global warming isn’t happening. “This winter was a temporary cold […]

12:00 PM | Counting Polar Bears From Space
The icy (and increasingly ice-free) Arctic is a forbidding place. It’s isolated, it’s remote. The weather is tumultuous. If the polar bears don’t get you, the cold will. That makes it tough to conduct surveys of wildlife populations. Walruses and ribbons seals are so hard to monitor that they’re classified by the IUCN as “data
