When climate denial and "alternative facts" pervade the body politic, it's time to zoom in on the science. Climate change is real and its effects are already visible—even more so when you can see them play out on the big screen.
The 15th Wild and Scenic Film Festival, in Nevada City in January, was rife with such evidence. Unlike most film festivals put on by big production companies, this one is produced by a nonprofit environmental organization called South Yuba River Citizens League—and powered by 700 of its volunteers. The organizers' passion is clear and so is their intent: to inspire audiences to take action on the challenges facing our planet. With climate change at the top of that particular list and 120 films running over the course of a weekend, it's safe to say this reviewer faced no shortage of opportunity to sit back, relax and learn.
From the gravely sobering, to the relentlessly hopeful, to the darkly comedic, this year's standout climate-related films showcased the range of feeling one might have about climate change. A few themes ran through each, however. Several pointed to a need for a complete transformation of the economic system, connecting the dots between energy, economy and environment. They also highlighted major momentum in the renewable energy sector. But most fundamentally, they went to the experts for the facts, then wove together compelling narratives to bring climate science—and action—to life.
Following are four recommendations for provocative, intelligently made films that can make audiences think, feel and act.
1. The Age of Consequences (Jared P. Scott, U.S. 2016)
This harrowing yet dispassionate story opens with stark footage (like this) of soldiers scrambling out of trenches, some to, some away from the mushroom cloud rising in the distance—a fitting introduction for a film that suggests we are already perilously close to a new order of global disaster. From there, tension is sustained throughout, as some of our nation's highest ranking military and State and Defense Department leaders walk us through eight concrete ways in which climate change is emerging as a grave threat to national security.
Graphically illustrating how years of unprecedented drought have contributed to the rise of radicalization in Syria, Afghanistan and Sudan, as well as catastrophes yet to come, such as sea-level rise and mass displacement in Bangladesh, the film lays bare the implications for global conflict. It also shows the vulnerabilities at home, from Katrina to Superstorm Sandy's crippling effects on New York City, to projections that the world's largest military base, in Norfolk, Virginia, is on track for frequent flooding as soon as 2040.
The film traverses the world and the offices and libraries of major military leaders to show the cascading impacts of climate-related disasters like extreme weather, drought, sea-level rise and food shortage on other pressures … like poverty, conflict, capacity issues and migration, all together making existing vulnerabilities even more fraught.
Throughout, we learn the many ways that leaders like former Secretaries of State Madeleine Albright and George Schultz and Marine Brigadier General Stephen Cheney have worked to call attention to the deep connection between security and climate change. And yet their warnings have often fallen on deaf ears, because some people still don't accept that climate change is happening.
In what may be the film's most memorable comment, former army officer and artillery tank driver Michael Breen points out that if 99 percent of intelligence experts told him there was an ambush ahead, he would listen—he wouldn't say there was a 1 percent chance of no ambush. In this age of consequences, the film suggests, we cannot afford to ignore the vast majority of scientists' warnings. And yet, Breen later argues, we're not even engaging in the first line of defense.
The story ends with a call to action. Just as the precise future of climate change impacts is unpredictable, so too is the human potential to rise to the challenge. Wrapping up with a veritable PSA for renewables and for programs that connect veterans with clean energy jobs, the film closes with the reminder that there is still time left to act. And time is the one resource we can't replenish.

Farms with just one or a handful of different crops encourage fewer species of pollinating and pest-controlling insects to linger, ultimately winnowing away crop yields, according to a new study.
Up to half of the detrimental impacts of the "landscape simplification" that monocropping entails come as a result of a diminished mix of ecosystem service-providing insects, a team of scientists reported Oct. 16 in the journal Science Advances.

"Our study shows that biodiversity is essential to ensure the provision of ecosystem services and to maintain a high and stable agricultural production," Matteo Dainese, the study's lead author and a biologist at Eurac Research in Bolzano, Italy, said in a statement.
It stands to reason that, with declines in the sheer numbers of insects that ferry pollen from plant to plant and keep crop-eating pests under control, these services will wane as well. But until now, it hasn't been clear how monocultures affect the number and mix of these species or how crop yields might change as a result.
Aiming to solve these questions, Dainese and his colleagues pulled together data from 89 studies cutting across a variety of landscapes, from the tropics of Asia and Africa to the higher latitudes of northern Europe. They tabulated the number of pollinating and pest-controlling insects at these sites — both the absolute number of individuals and the number of species — along with an assessment of the ecosystem services the insects provided.
In almost all of the studies they looked at, the team found that a more diverse pool of these species translated into more pollination and greater pest control. They also showed that simplified landscapes supported fewer species of service-providing insects, which ultimately led to lower crop yields.
The researchers also looked at a third measure of the makeup of insect populations — what they called "evenness." In natural ecosystems, a handful of dominant species with many more individuals typically live alongside a higher number of rarer species. The team found as landscapes became less diverse, dominant species numbers dwindled and rare species gained ground. This resulting, more equitable mix led to less pollination (though it didn't end up affecting pest control).
"Our study provides strong empirical support for the potential benefits of new pathways to sustainable agriculture that aim to reconcile the protection of biodiversity and the production of food for increasing human populations," Ingolf Steffan-Dewenter, one of the study's authors and an animal ecologist at the University of Würzburg in Germany, said in the statement.
The scientists figure that the richness of pollinator species explains around a third of the harmful impacts of less diverse landscapes, while the richness of pest-controlling species accounts for about half of the same measure. In their view, the results of their research point to the need to protect biodiversity on and around crops in an uncertain future.
"Under future conditions with ongoing global change and more frequent extreme climate events, the value of farmland biodiversity ensuring resilience against environmental disturbances will become even more important," Steffan-Dewenter said.

Greenland had quite the summer. It rose from peaceful obscurity to global headliner as ice melted so swiftly and massively that many were left grasping for adjectives. Then, Greenland's profile was further boosted, albeit not to its delight, when President Trump expressed interest in buying it, only to be summarily dismissed by the Danish prime minister.
During that time I happened to be in East Greenland, both as an observer of the stark effects of climate change and as a witness to local dialogue about presidential real estate aspirations, polar bear migrations and Greenland's sudden emergence as a trending topic.

Creepy-crawlies are among the oldest life forms on this planet. Before dinosaurs ever walked the earth, insects were certainly already there. Some estimates date their origins to 400 million years ago. They're also extremely successful. Of the 7 to 8 million species documented on Earth, around three quarters are likely bugs.
But several insect species could disappear for good in the next few decades and that would have serious consequences for humans.
