Why Plants Are Seeding Climate Studies

The National Museum of Natural History’s herbarium is helping botanists research climate-driven changes in plants, their biology and their abundance

Warming temperatures allowed archaeologists to begin examining the barracks, which had previously been sealed off by a glacier, in 2017.

What Fossil Plants Reveal About Climate Change

Paleobiologists use fossil plants to reconstruct Earth’s past climate and inform climate change research today.

Hillary Hughes, Panamanian actress, visits the Smithsonian Tropical Research Institute's Agua Salud Project during the filming of videos in Spanish and English to share hope for the success of tropical forest reforestation informed by the largest experiment of its kind in the tropics.

Xiulin Ruan, a Purdue University professor of mechanical engineering, holds up his lab’s sample of the whitest paint on record.

Innovation for Good

This Ultra-White Paint May Someday Replace Air Conditioning

Developed by researchers at Purdue University, the paint reflects 98.1 percent of sunlight

The newly rediscovered species, Coffea stenophylla, has black fruit or cherries surrounding its "beans" which are actually seeds. Plant researchers are excited by the species' tolerance of higher temperatures and desirable flavor characteristics.

New Research

Rediscovered Coffee Species Boosts Crop’s Climate Resilience Without Sacrificing Taste

The rare, wild species was well-received by taste-testers and can grow in much higher temperatures than the most commonly cultivated varieties

Smoke rises from a wildfire in the summer of 2019 near Talkeetna, Alaska.

New Research

New-Growth Alaskan Forests May Store More Carbon After Wildfires

Researchers find forests are regrowing with more deciduous trees, which are more resistant to burning and may eventually store 160 percent more carbon

Landscapes have been managed by humans for thousands of years – some sustainably, others less so. The Martu people of Australia burn the grasses in continent’s Western Desert. The practice yields food, but also increases biodiversity in the area.

A lightning-caused wildfire in 2013 creates white smoke rising from the tundra in front of the Baird Mountains.

New Research

Climate Change Linked to Increase in Arctic Lightning Strikes

A warming climate makes Arctic lightning possible, and resulting wildfires release immense amounts of carbon from the permafrost

New research says the United States would need to more than double its current seedling production to add 30 billion trees by 2040.

New Research

To Fight Climate Change With Trees, America Needs More Seedlings

New research estimates the U.S. would need to double production to meet its reforestation goals

A study of ten narwhal tusks reveals how the animals are responding to a swiftly changing Arctic.

The founder of Climate Cardinals assembled a team of global volunteers to breakdown language barriers by translating climate science and research

Damages wrought by climate change and deforestation have transformed the Amazon rainforest. New research suggests the changes to this icon of the natural world caused by human activity may mean the Amazon now emits more greenhouse gases than it absorbs.

New Research

The Amazon Rainforest Now Emits More Greenhouse Gases Than It Absorbs

Climate change and deforestation have transformed the ecosystem into a net source of planet-warming gases instead of a carbon sink

This cow was fed a small amount of seaweed along with its feed to reduce methane emissions from its burps.

New Research
