-----------------------------------------------------------------


Major ecosystem changes like sea-level rise, desertification and lake warming are fueling uncertainty about the future. Many initiatives - such as those fighting to fully eradicate non-native species, or to combat wildfires - focus on actively resisting change to preserve a slice of the past.

However, resisting ecosystem transformation is not always a feasible approach. According to a new paper published today in the Ecological Society of America's journal Frontiers in Ecology and the Environment <https://esajournals.onlinelibrary.wiley.com/doi/full/10.1002/fee.2377>, accepting and directing ecosystem change are also viable responses, and should not necessarily be viewed as fallback options or as last resorts. The paper presents a set of guiding principles for applying a "RAD" strategy - a framework that involves either resisting, accepting or directing ecosystem changes.

"We are facing the harsh reality that, in some locations, ecosystems are transforming at such a pace that we won't be able to restore or rehabilitate them to what they once were," said Abigail Lynch, the paper's lead author and a research fish biologist at the United States Geological Survey (USGS) National Climate Adaptation Science Center. "The RAD framework provides a common language for starting productive conversations about what comes next - when we need to consider options to accept and direct change in addition to just trying to resist it."

The paper was a collaborative effort by 20 federal, state and academic researchers from across the United States. It zeroes in on three National Wildlife Refuges (NWRs) along the East Coast, where sea-level rise is increasing at three to four times the global average rate and transforming ecosystems and local communities. Managers of the three NWRs have applied all three of the responses outlined in the paper:

John H Chafee NWR (Rhode Island): managers are resisting the effects of sea-level rise by depositing dredged sediment on waterlogged salt marshes and securing the sediment with bags of recycled oyster shells.
Chincoteague NWR (Virginia): After years of resisting dune overwash, managers are now allowing storm-induced waves to fill in waterfowl impoundments, accepting the landward transport of sand and moving National Park Service visitor infrastructure.
Blackwater NWR (Maryland): Managers are directing the effects of sea-level rise by facilitating marsh migration upwards. Assisted marsh migration is ten times cheaper than trying to restore marsh in situ.

According to Erik Beever, a research ecologist at the USGS Northern Rocky Mountain Science Center, research affiliate faculty at Montana State University and a coauthor of the paper, the importance of considering costs and benefits is paramount when selecting a course of action within the RAD framework.

"A 'resist' approach may involve less cost in the immediate term or may allow the persistence of a culturally treasured species, but it may involve substantially higher costs over the course of a period as short as 10-15 years," said Beever. "For example, if that treasured species' bioclimatic niche no longer occurs within the management area, facilitating its persistence will require more intensive and more costly efforts."

Accepting ecosystem change can involve a fundamental shift in the way of life for communities that rely on an ecosystem's goods and services. However, solutions that focus on resisting change are becoming increasingly impractical as ecological changes occur more frequently and more dramatically. The paper contends that three broad feasibility criteria - ecological, societal, and financial - must be considered when deciding which RAD strategy is most suitable.

Natural resource managers are using options from within the RAD framework to tackle a variety of problems across many different systems, including:

Loss of corals in the Mexican state of Quintana Roo
Spruce bark beetle epidemic and wildfires on Alaska's Kenai peninsula, where white spruce forests are transforming into grasslands
Projected decline of cisco populations under warming conditions in Minnesota lakes
In the RAD framework, accepting change is not a passive approach; rather, it is a deliberate course of action geared toward a defined set of objectives. While the framework still needs to be tested and fine-tuned, the authors ultimately view it as a strategy of empowerment.

"It might be tempting to throw one's hands up in the air when faced with drastic and transformative environmental change, but there are options available," said Laura Thompson, a coauthor who is a research ecologist at the USGS National Climate Adaptation Science Center and adjunct faculty member at the University of Tennessee, Knoxville. "This RAD framework provides the full range of strategies."

“A death zone is creeping over the surface of Earth, gaining a little more ground each year. 

As an analysis published this week in Nature Climate Change shows, since 1980, these temporary hells on Earth have opened up hundreds of times to take life (C. Mora et al. Nature Clim. Change http://dx.doi.org/10.1038/nclimate3322 <http://dx.doi.org/10.1038/nclimate3322>; 2017). 

“The analysis also reveals that even aggressive reductions in emissions will lead the number of deadly heatwaves to soar in the coming decades.

Book review : Under the Sky We Make. Kimberly Nicholas, PhD

Excerpt : Individual responsibility has become something of a flashpoint in the climate discourse. 

On the one hand, oil companies love to harp on about <https://grist.org/energy/footprint-fantasy/> personal carbon footprints as a way of distracting from their much larger contributions to the climate crisis, both through the fossil fuel products they make and their longstanding, ongoing efforts to delay climate action and misinform the public. 

At the same time, prominent journalists and scientists have waved off individual climate actions as a distraction from the systemic changes that are needed to solve the crisis — changes like overhauling our electricity and transit systems through governmental investments in clean energy, better regulation, and carbon pricing. 

They’re joined by a growing chorus of climate justice advocates who rightly point out that asking poor people to make difficult dietary shifts or give up the car they need to get to work is completely unfair.

That’s not what Nicholas is doing. Her message isn’t aimed at folks struggling to make ends meet, but at people making a middle-class income or higher who live in a wealthy country like the United States, Germany, or France. Far from a distraction, Nicholas argues that the climate impact of the carbon elite is something we need to focus on — individually    and systematically. She points out that globally, more than two-thirds of climate pollution can be attributed to household consumption <https://pubs.acs.org/doi/10.1021/es803496a>, and that the richest 10 percent of the world population — those making more than $38,000 a year <https://wedocs.unep.org/xmlui/bitstream/handle/20.500.11822/34432/EGR20ch6.pdf?sequence=3> — is responsible for about half of those emissions.
