The American media lends too much weight to people who dismiss climate change, giving them legitimacy they haven’t earned, posing serious danger to efforts aimed at raising public awareness and motivating rapid action, a new study shows.

While it is not uncommon for media outlets to interview climate change scientists and climate change deniers in the same interviews, the effort to offer a 360-degree view is creating a false balance between trained climate scientists and those who lack scientific training, such as politicians.

The most extreme drought event in hundreds of years caused a catastrophic die-off of the Sierra Nevada’s mature trees in 2015-2016.

A study published today in Nature Geoscience details how UC Merced Professor Roger Bales and his colleague Professor Michael Goulden from UC Irvine tracked the progress of the devastation caused by years of dry conditions combined with abnormally warm temperatures.

Climate change is bad news for forests, and a new study by UC Merced Professor Emily Moran demonstrates one aspect of that news.

Higher summer temperatures hurt tree seedlings’ growth and survival.

But whether that is entirely bad depends on the degree of change in the number of young trees.

Most people wouldn’t think sharks can teach researchers about the planet’s distant past and its more immediate future.

UC Merced paleoecologist Professor Sora Kim isn’t most people.

There’s a connection between data in fossilized shark teeth and climate change, and thanks to a grant from the National Science Foundation, she aims to use that information to better understand climate change.

Under the leadership of Professors Asmeret Berhe and Stephen Hart, three UC Merced Environmental Systems (ES) graduate students have been awarded fellowships from the U.S. Department of Energy (DOE) to advance their doctoral theses.

Two UC Merced Ph.D. students took to the State Capitol yesterday with representatives from the other UC campuses to advocate for the importance of the research being done across California.

Climate change is having a profound effect on the millions of migrating birds that rely on annual stops along the Pacific Flyway as they head from Alaska to Patagonia each year.

They are finding less food, saltier water and fewer places to breed and rest on their long journeys, according to a new paper in Nature’s Scientific Reports.

It’s estimated that a leaf-cutter ant colony can strip an average tree of its foliage in a day, and that more than 17 percent of leaf production by plants surrounding a colony goes straight into their giant, fungus-growing nests.

It’s no wonder these ants are considered the smallest recyclers on the planet and are referred to as "ecosystem engineers" by scientists because of the effects they have on the environment around them.

Climate change and wildfire make a combustible mix with deadly and costly consequences.

Scientists have been trying to understand that link for many years, studying the effects of climate and wildfire interactions in the Sierra Nevada.

UC Merced Professor LeRoy Westerling and University of New Mexico Professor Matthew Hurteau and colleagues have analyzed data via simulations of Sierra wildfires, and what they found was surprising.
