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 ...

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.”

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.

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.

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 ...

The Adirondacks region of New York is famous for its brook trout fishing. But as the climate warms, this cold-water fish is in trouble.
Stephen Jane is a postdoctoral fellow at Notre Dame University. He says in the summer, the sun warms the water near a lake’s surface. Warm water is less dense than cold water, so it forms a layer that floats on top of the cooler water below.
Jane: “In many lakes, it stays that way until late in the fall when the air temperatures cool down.”
That top layer can get too hot for brook trout. And it’s getting ... Read more ...

If you go to a city park on a hot, summer day, you might sit under a big, shady tree to cool off.
But that tree is helping you beat the heat, even when you’re not standing directly under it.
One study found that on very hot days, greener areas of Baltimore and Washington, D.C. can be more than 15 degrees cooler than areas of those same cities with fewer trees.
One reason for this dramatic difference in temperatures is that dark-colored roads and rooftops get scorchingly hot when the sun shines down on them. Then those surfaces release the ... Read more ...

Among the most consequential effects of a warming globe is the disruption or even destruction of habitats for plants and animals, from the blue whales and giant sequoias to the tiniest of bacteria. Some species are mobile and flexible enough that they can move or adapt on their own - by, say, moving uphill or toward the poles. Others, like sequoias, are not so lucky; woven into their current locations by multiple factors, they lack the capacity to change as quickly as the climate and ecosystem around them. These species may need a little help from humans. ... Read more ...

Arah Narida leans over a microscope to gaze into a plastic petri dish containing a hood coral. The animal - a pebbled blue-white disk roughly half the size of a pencil eraser - is a marvel. Just three weeks ago, the coral was smaller than a grain of rice. It was also frozen solid. That is, until Narida, a graduate student at National Sun Yat-sen University in Taiwan, thawed it with the zap of a laser. Now, just beneath the coral’s tentacles, she spies a slight divot in the skeleton where a second coral is beginning to bud. That small cavity is evidence that ... Read more ...

Scattered along the Eastern seaboard and Gulf Coast, grassy salt marshes provide habitat for birds and marine life.
They help protect coastal communities from flooding by absorbing wave energy and soaking up water.
And they store a lot of carbon because when marsh grasses die, they fall into waterlogged soils.
It’s a low-oxygen environment where plants break down very slowly, so all that carbon-rich material builds up over time.
