Mountaintops get less lonely for alpine plants

It takes a hardy plant to live on top of a mountain, but new research shows that summits in the Alps are hosting more species of plants than ever before. Long-term botany surveys conducted on 302 European mountaintops over the past 145 years show that the variety of plant species living on the harsh summits has markedly increased over the last 10 years due to climate change.

Comment: The changing shape of local climates

Climate is changing globally, but how will it be experienced locally? Researchers are developing the techniques needed to understand and predict the local consequences of global change.

Down to Earth With: Conservation engineer Emily Pidgeon

“I can be a very blunt object,” says Emily Pidgeon, describing how she moves through the world and how she approaches her work. Her Australian accent, drawling yet punctuated, rises above the din of the lunch crowd at a café. She pauses a moment, and declares herself a larrikin. “Do you know that word, larrikin?” She explains that Australians have a larrikin culture — they’re troublemakers, but in a good way. “We have a healthy disrespect for authority,” she says, sipping her tea.

Comment: Arctic warming and midlatitude weather: Is there a connection?

Over the last few decades, the Arctic has warmed more than the rest of the planet, but is this Arctic amplification influencing weather patterns in the middle latitudes?

What drives hot spots of sea-level rise?

As sea levels creep up around the world, scientists have observed hot spots where regional rates of sea-level rise greatly outpace the global average. But what drives the formation of these hot spots, and how long they last, have been mysteries. In a new study, scientists tracking sea levels along the Florida coast suggest that the combined effects of two naturally occurring climate processes, the El Niño-Southern Oscillation (ENSO) and the North Atlantic Oscillation (NAO), control sea-level hot spot formation along the U.S. East Coast.

Geomedia: Books: Earth faces challenges, but are they tipping points?

The 2016 book, “Tipping Point for Planet Earth,” by paleoecologists Anthony D. Barnosky and Elizabeth A. Hadly, is a serious book on a serious topic, and a well-written, one-stop resource for anyone who wants to understand a host of looming problems. The book focuses on the alarming number of worrisome planetary trends now underway, mainly as a result of the convergence of population growth and human-induced global warming. Chapters cover people (population growth), “stuff” (increased purchases of material goods), storms, hunger, thirst (failing water supplies, clean or not), toxins, disease and war. These trends have merited serious attention from environmental scientists and deserve the same from politicians. Whether they are tipping points, however, is a point of contention.

Delusions of grandeur in building a low-carbon future

Traditional macroeconomic models provide an unstable foundation for decision-making when planning for a low-carbon future. To maximize our ability to achieve our future energy, climate and economic goals, economic modeling concepts must be improved.

More than a nuisance: Over time, small floods cost more than extreme events

Devastating storms like Hurricanes Katrina and Sandy dominate public attention when they hit, causing massive amounts of damage from high winds and waters. But small floods driven by rising seas may end up costing some coastal areas more in the long run. According to a new study published in the journal Earth’s Future, the cumulative property damage from these so-called nuisance floods could eventually match or exceed costs from rare extreme storms.

Burying the sky: Turning carbon dioxide into rock

At an Icelandic geothermal power plant, researchers are capturing carbon dioxide and burying it in basalt to keep the greenhouse gas out of the sky. But can this method be scaled up, and work elsewhere, to help meet global climate goals?
