Ancient Climates

Interweaving a grand historical narrative with cutting-edge climate science and genetic discoveries, Kyle Harper traces how the fate of Rome was decided not just by emperors, soldiers, and barbarians but also by volcanic eruptions, solar cycles, climate instability, and devastating viruses and bacteria. He takes listeners from Rome's pinnacle in the second century, when the empire seemed an invincible superpower, to its unraveling by the seventh century, when Rome was politically fragmented and materially depleted.

In the form of several journeys, beginning in January 2019, Neil Ansell returns for solitary walks to the New Forest in Hampshire, close to where he was born. With beautiful sightings and observations of birds, trees, butterflies, insects and landscape, this is also a reflective memoir on childhood, on the history of one of the most ancient and important natural habitats in the United Kingdom and on the Gypsies who lived there for centuries - and were subsequently expelled to neighbouring cities.

Glaciers figure prominently in both ancient and contemporary narratives around the world. They inspire art and literature. They spark both fear and awe. And they give and take life. In The Age of Melt, environmental journalist Lisa Baril explores the deep-rooted cultural connection between humans and ice through time.

Recently recovered from his epic bicycle journey that took him from the Delaware shore to the Oregon coast, distinguished climate scientist David Goodrich sets out on his bike again to traverse the Western Interior Seaway - an ancient ocean that once spread across half of North America. When the waters cleared a geologic age ago, what was left behind was vast flat prairie, otherworldly rock formations, and oil shale deposits.

As a basic definition, it may be said that an Ice Age is simply a period of time during which thick ice sheets cover vast areas of land. These sheets have advanced and retreated, at times taking over the entire planet, and conversely disappearing nearly altogether. Glacial ice formed by this regularly occurring process does not sit in a state of inertia, but moves dynamically, reshaping the geological features of the continents.
