The engineer views a landfill as a living ecosystem, and the plastic that clogs it as a serious threat that crowds out life and never goes away. Can we eliminate the waste before it smothers us?

Scientists have been analyzing bones first uncovered by a utility crew digging at the Manassas National Battlefield Park in Virginia. The remains provide insights into surgery during the Civil War.

Biologists knew the sharks sometimes traveled from waters off Costa Rica south to the Galapagos Islands, but they'd never actually witnessed it.

The two satellites, which are collectively called GRACE and will replace two retired probes, are one of the most important tools for understanding the effects of climate change.

From bass to lobster, hundreds of species that live along U.S. coastlines are projected to migrate north over the next 80 years, making them harder to catch and manage. It's already happening.

New research shows how scorching temperatures in the Gulf of Mexico led to massive rainfall when the storm hit last year. The findings also suggest global warming will make the problem worse.

Plus-sized mama fish have a size advantage over their petite counterparts: They can produce more eggs, and those eggs produce larger fish. It's a reminder that protecting big fish matters.

Global warming has so far seen a gradual rise in average temperatures. But that may change, with extreme variations. And poor countries could bear the brunt of it.

As humans spread around the globe, other big mammals vanished. Researchers believe it's because they were tasty.

Extreme weather cost Americans over $300 billion last year. Scientists say climate change will bring more of that. Entrepreneurs and businesses see a new market in gauging risk.

Scientists hope MethaneSAT will show where the potent greenhouse gas is coming from. Tracking methane in the air is difficult because it rises and spreads from the source.

Turning food waste into fertilizer is popular in parts of Europe and is catching on in the U.S. But tiny plastics are also making their way into that fertilizer — and into the food chain.

Energy analysts are getting worse at predicting how much oil and gas will come out of the ground in the future, a new study finds.

The most thorough examination of the infamous "Pacific Garbage Patch"-- a floating swath of debris caught in a gyre — shows it's bigger, way bigger, than thought. And it's mostly plastic.

In total, scientists say there are about 79,000 tons of plastic in this area, which is more than double the size of Texas.

The report, obtained by NPR, shows that "sunny-day flooding" may be a regular occurrence in some areas. It sets out to give communities a clear guide to prepare for coastal flooding.

Scientists say some of the earliest cave art found in Europe was done before humans arrived; thus, Neanderthal art, suggesting that our "brutish" cousins were capable of symbolic thinking.

The Trump administration could give companies permission to set off sonic explosions to explore for oil and gas deposits. Scientists say this could seriously harm marine life.

Hurricanes, fires and even hail contributed to billions of dollars in damages. The government study also finds that it was among the warmest years on record.

A discovery of the remains of two infants in central Alaska provides evidence of the earliest wave of people to move from Asia into the Americas.
