In the Western U.S., small mesh cages adorn the towering whitebark pines that dot high-elevation landscapes.
The cages have been placed around the trees’ pine cones to protect their increasingly precious contents: seeds.
The survival of the slow-growing whitebark pine is threatened by an array of pressures: an invasive fungus called blister rust, a hungry beetle, and wildfires that have grown increasingly intense on a landscape parched by human-caused climate change.
Blister rust arrived in the United States from Asia around the year 1900. ... Read more ...

Thinning dense forests can help reduce the risk of intense wildfires as the climate warms.
But getting forest restoration work funded can take a long time – and hold up this critical work.
So the nonprofit Blue Forest created a new approach to financing projects.
Anna Yip of Blue Forest says private investors fund what’s called a forest resilience bond. It provides the upfront capital needed for the Forest Service or other partner to do the restoration work.
Yip: “The financing dollars allow for the implementation to happen at a ... Read more ...

When it rains, the Duck Creek Tributary in northwest Indiana often floods, filling nearby roads with water.
Schleizer: “When it floods, it gets real messy … so people were, you know, getting stuck and not being able to travel like they used to.”
Bill Schleizer is with the nonprofit Delta Institute.
He says during storms, pollution from farms, road salt, and sediment also wash into the creek. And as climate change brings more intense rain, the risk of flooding is growing.
So Schleizer’s group is working with local officials to restore ... Read more ...

Fireflies face 'one-two punch’ of climate change, habitat loss, and light pollution - Yale Climate Connections - Ecosystems (Sep 05, 2024) |

On warm summer evenings across the U.S., you can glimpse the twinkling lights of fireflies.
These magical insects are threatened by light pollution and habitat loss. But a new study adds another risk to that list: climate change.
McNeil: “Those factors … coupled with the effects of climate change are probably going to be the one-two punch for many firefly populations.”
D.J. McNeil is an ecologist at the University of Kentucky.
He and his colleagues studied the relationship between environmental conditions and firefly numbers, using ... Read more ...

In 2020, about 200 volunteers helped plant trees at Crosby Farm Regional Park near the Mississippi River in Saint Paul, Minnesota.
They helped launch a 20-year project that seeks to identify which tree species will grow well in the region as the climate warms and precipitation becomes more extreme.
Emma Vanhdy of the nonprofit Mississippi Park Connection coordinates volunteers for the project.
She says they planted more than 1,000 trees across 24 research plots. Some plots contain species already common in the area.
Vanhdy: “So mainly ... Read more ...

As climate change has caused warmer winters, an invasive insect called the hemlock woolly adelgid has spread across forests in the Eastern U.S., killing hemlock trees from Maine to Alabama.
And scientists are worried that this insect’s spread could also accelerate climate change.
Hemlocks, like other trees, absorb planet-warming carbon from the atmosphere as they grow.
Danielle Ignace of the University of British Columbia explains that when hemlock needles fall, the carbon they contain is stored in the soil for a long time.
Ignace: ... Read more ...

For 20 years now, Ken Nedimyer has been strapping on his scuba gear and diving into the waters off the Florida coast in a desperate effort to restore coral reefs that have been decimated by climate change and pollution. In 2019, he founded his latest venture, Reef Renewal USA. The group’s YouTube channel shows Nedimyer and other members underwater, carefully attaching nursery-grown coral to structures designed to build healthy reefs.
“We’re working hard under pressure with innovation, speed, and efficiency to repopulate our coral reefs,” the narrator says. Read more ...

Climate change threatens the already endangered Karner blue butterfly - Yale Climate Connections - Ecosystems (Aug 16, 2024) |

The Karner blue – a tiny, powder blue butterfly – used to live in oak savannas and pine barrens across the Midwest and Northeast.
But over time, much of the Karner blue’s habitat has been destroyed – and today only a few small populations remain in places like Michigan, Wisconsin, and New York.
Now climate change is posing a whole new threat to this endangered butterfly.
Karner blue caterpillars only eat a plant called wild lupine. But as winters have grown warmer, the caterpillars have started hatching earlier in the year, before the ... Read more ...

In the Rocky Mountains, vast areas of whitebark pine trees have been killed by wildfires, mountain pine beetles, and a fungus called blister rust.
But even in hard-hit areas, a handful of trees survive.
Durglo: “There in the middle of all these dead hundreds of trees, you’ll see a green one.”
That’s Mike Durglo of the Confederated Salish and Kootenai Tribes in Montana.
He says whitebark pines provide vital wildlife habitat. And their shade helps slow down mountain snowmelt. For communities downstream, that helps reduce the risk ... Read more ...

The climate benefits of mangroves - Yale Climate Connections - Ecosystems (Jul 15, 2024) |

Yale Climate Connections
Mangroves are trees and shrubs that grow in thick groves right along the ocean’s edge, often with a tangle of roots and branches that weave in and out of the water.
During a storm, these roots and branches can help calm choppy waves and reduce the risk of flood damage farther inland.
So as climate change creates more extreme weather, mangrove thickets can help protect coastal communities from increasingly intense storms.
Mangroves can also help reduce global warming.
That’s because mangroves grow very quickly. And as they grow, they ... Read more ...
