Solar geoengineering research aims to reduce the impacts of global climate change. One possibility is to put aerosols into the stratosphere to alter Earth’s energy budget. This emerging technology entails risks and uncertainties, along with serious challenges to global governance. The greatest threat, perhaps, is that it will be used as a technical fix and encourage people to avoid the emissions cuts that are fundamental to curbing long-term climate risks.
Lecturer David Keith will describe the simple physics underlying the climate’s response to stratospheric aerosols, the...

Garden in the Woods, 180 Hemenway Road, Framingham
Explore the vast variety of native trees, shrubs, and woody vines. Learn which species grow well in shade, which support local wildlife, and how to stagger plantings for continuous bloom, fruit production, and fall color. The class discusses growth characteristics, cultural requirements, and best horticultural uses. It begins with lectures and walks at Garden in the Woods in Framingham and includes a field trip to the Arnold Arboretum in...

Capture the drama of fall, when landscapes present a vivid array of colors and the palette is most striking. Professional photographer Nancy Katz will introduce fundamental concepts of landscape photography and then teach techniques for getting the best photographs from your smartphone camera. You will capture images in dynamic color and muted shades, then learn to enhance them using a host of editing tools provided in the Snapseed App. For best results, bring your smartphone and a commitment to completing the weekly homework assignments. Class will take place indoors and out.

Celebrate National Fossil Day with ancient trilobites, sea scorpions, saber-toothed cats, giant ground sloths, and more. Meet Harvard paleontologists and learn about the amazing prehistoric animals on exhibit. Bring your curiosity and questions to this event for all ages!
As the earliest farmers began to select wild plants and animals that had desirable traits, they initiated a series of genetic changes in these species that gradually made them more suitable for agriculture. Plants became easier to grow, had greater yields, and were of higher quality. Animal species exhibited favorable changes in behavior, coat color, and reproductive traits. Barbara Schaal will discuss how the artificial selection of these species—a pivotal technological achievement—has influenced their genetics, evolution, and capacity to flourish in the care of humans.
Harvard Museum of Natural History, 26 Oxford St., Cambridge
Celebrate reptiles! Join Harvard students from the Harvard College Conservation Society for a variety of reptile themed activities including a scavenger hunt, storytime, and crafts. Come learn about the history and diversity of reptiles, and why they need to be conserved! All ages are welcome.
Please note: Regular museum admission rates apply.
Dana Greenhouse, Arnold Arboretum, 125 Arborway, Boston
When our staff returns from seed collecting in the wild, there is little time for rest. Arboretum staff Andrew Gapinski, Sean Halloran, and Jared Rubinstein will travel for three weeks this September in Appalachia in search of seed from taxa targeted as part of the ...
Hunnewell Building, Arnold Arboretum, 125 Arborway, Boston
The Arnold Arboretum provides both extensively documented collections for research and the facilities for the researchers—labs, greenhouses, and growing chambers. From around the world, scientists come to use the trees and shrubs in the Arboretum landscape, studying climate change, plant evolution, natural selection, and species adaptation. Join docent Esther Miller to hear about the science of the Arboretum.
Adolescence is dangerous, difficult, and destiny-shaping for humans and other animals. In Wildhood (Simon & Schuster, 2019), Barbara Natterson-Horowitz and Kathryn Bowers look across species and evolutionary time to find answers to a single, consequential question: Why do some adolescents safely, successfully, and independently enter the adult world, while so many others do not? The authors apply the results of their five-year study of wild animal adolescence to our species, presenting a new understanding of the dangers, stresses, and challenges we face on our journeys to...
In this performance-based lecture, the globe-trotting magician Joshua Jay will pull back the curtain on the way magicians think. He will explore how magicians achieve the seemingly impossible and how people can apply the same strategies to their own lives and work.
Hunnewell Building, Arnold Arboretum, 125 Arborway, Boston
With nearly 4,000 different kinds of plants represented in the Arboretum's living collections, every day presents rich opportunities to see something new. If you enjoy learning about plants and their unique characteristics, you can contribute to science as a participant in the Arnold Arboretum's Tree Spotters program. This citizen science project opens a window into the Arboretum's phenology: the timing of natural events, such as the leafing out and flowering of trees in the spring and changing foliage colors in the fall. Your observations will assist Arboretum scientists in their...
The Special Exhibitions Gallery, Science Center 251, 1 Oxford St., Cambridge
This exhibit features images and objects drawn from a variety of disciplines and time periods that show the importance of visual experiences in science. Images have played many roles in scientific research. Images can record fleeting observations, whether a painting of an animal glimpsed in the field or an interaction between sub-atomic particles that lasts a millisecond. They can also make unseen things visible.
Physical models can make abstract mathematical concepts into something that researchers can touch; properly arranged, sand, metal plates, and a violin bow can make...
Edo Berger, professor of astronomy at Harvard University, will discuss his efforts to explore the long-standing question of how gold and other heavy elements are created in the universe. In particular, his work aims to demonstrate the creation of these elements in neutron star collisions detected through their gravitational wave emission and the implications of the answer.
Ancient Maya civilization—known for its cities, monumental architecture, ceramics, hieroglyphic writing, and advanced understanding of mathematics and astronomy—suffered a major demise between the tenth and eleventh centuries. The causes continue to be investigated and debated. Paleoenvironmental research over the past twenty years has revealed that the demise coincided with a prolonged intensive drought that extended across the region, providing compelling evidence that climate change played a key role in the collapse of the Maya.

Dinosaur fossils were first found in England, but a series of late-nineteenth-century discoveries in the American West turned the United States into a world center for vertebrate paleontology. Around the same time, the United States also emerged as an economic powerhouse of global proportions, and large, fierce, and spectacular creatures...
