Fire ecologists are urging forest managers to allow more wildfires to burn on the landscape to help thin overgrown forests. Many challenges stand in the way.

The administration is proposing to substantially weaken President Barack Obama's signature rule on climate change. It would give states more power to regulate carbon emissions from coal plants.

President Trump is expected to announce a new plan this week for regulating carbon emissions from coal plants. It will weaken one of President Obama's signature policies for addressing climate change.

Massive wildfires in Western states are rapidly depleting funds set aside to fight fires. At the same time, many experts argue our priorities are wrong — we should be spending more on prescribed burns, and less on fighting fires in unpopulated areas.

Over more than three months, lava from Kilauea inundated two seaside communities and reshaped the island's southeast coast. But while activity has lessened, it doesn't mean the eruption has ended.

The Trump administration wants to roll back some rules for endangered species. Environmentalists say it could mean more species go extinct.

A warming climate is knocking nature's rhythms out of sync. High in the Rocky Mountains, scientists have been tracking the impact for decades.

Researchers at the Scripps Institution of Oceanography hope to turn surfers into citizen scientists by equipping them with a "smartfin" that gathers data as they surf.

Scandal-plagued EPA Administrator Scott Pruitt has resigned from his post, leaving many environmental regulatory rollbacks at the agency up in the air.

Lava from Kilauea volcano has filled Kapoho Bay and inundated a section of coastline that was once covered with lush forest and dotted by homes.

The eruption of Kilauea on Hawaii's Big Island is causing local devastation, but it is an exciting research opportunity for volcanologists.

The spectacular lava fountains and fissures on Hawaii's Big Island are scaring the tourists away. That's a big problem for an island whose economy is heavily dependent on visitor dollars.

The evacuated housing development at Leilani Estates was built on the flank of the volcano. Some people wonder why anyone would ever live there. The answer? The homes are affordable.

Hawaii officials continue to warn the public about dangers from the active volcano on the Big Island, including the lava flowing toward a power plant. In the meantime, they are trying to reassure possible visitors that the tourism opportunities have not been affected.

Over 40 structures have been destroyed and thousands remain evacuated as the volcano erupts. Lava flows from dozens of fissures have reached the ocean, creating a dangerous phenomenon known as "laze."

Environmental Protection Agency chief Scott Pruitt often cites the need for "regulatory certainty." But even some supporters of his sweeping rollbacks say they're creating the opposite.

EPA chief Scott Pruitt is praised by industry and conservatives for his aggressive moves to roll back environmental regulations. But how much he's changed the department is debatable.
