In Storms of My Grandchildren, James Hansen - the nation's leading scientist on climate issues - speaks out for the first time with the full truth about global warming: the planet is hurtling even more rapidly than previously acknowledged to a climatic point of no return. Although Hansen was Al Gore's science adviser for the 2006 documentary An Inconvenient Truth, his recent data shows that our situation is even more dire today.

Chris Mooney, author of The Republican War on Science and one of the leading young environmental journalists and bloggers working today, immerses listeners in the world of those who study hurricanes. What was once an arcane branch of meteorology (itself an arcane science) has become embroiled in one of the most politicized and hotly contested debates in American science: whether or not the recent hurricane disasters, culminating in Katrina, are connected to global warming.

Around 13,000 years ago, three things happened at once: (1) Global temperature suddenly stopped rising and plunged back to ice age-frigidity. (2) The Western Hemisphere’s largest mammals, including the horse, camel, woolly mammoth, saber-toothed cat, and dozens more, went extinct. And (3) the uniquely beautiful stonework of the early American Clovis people disappeared from the archeological record. For the past half-century, scientists have struggled to explain the three events. Were they independent of each other, or could they have had a common cause?

A fascinating, comprehensive, accessible account of conodont fossils—one of paleontology's greatest mysteries. Simon J. Knell takes the listener on a journey through 150 years of scientific thinking, imagining, and arguing. Slowly the animal begins to reveal traces of itself: its lifestyle, its remarkable evolution, its witnessing of great catastrophes, its movements over the surface of the planet, and finally its anatomy. Today the conodont animal remains perhaps the most disputed creature in the zoological world.

Fire is rarely out of the headlines, from large natural wildfires raging across the Australian or Californian countrysides to the burning of buildings such as the disasters of Grenfell tower and Notre Dame. Fire on these scales can represent a serious risk to human life and property. But the advent of fire made and controlled by humans also represented a crucial point in our evolution, allowing us to cook our food, forge our weapons, and warm our homes.

Using the lessons of Noah's ark, Micheal Levine, founder and owner of Levine Communications, based in Los Angeles, offers a lighthearted approach to the serious business of taking stock, taking control, and transforming calamity into opportunity.

An experienced geologist with years of study in sedimentology, Chris Severson shares his passion for the Delta at the mouth of the Mississippi River. Introduced to the Delta as a young adult, the author ventures into this wild and fascinating region for many, many years. The stories herein tell of adventure, mishaps and perils while giving a view into the beauty of the delta and a geologic picture of the building and destructive forces at work to have created this ever changing, amazing landscape.

There's so much we don't know about what lies deep beneath the ocean's surface - and the time to find out is growing increasingly precious . . . Professor Alex Rogers is one of the world's leading experts in marine biology and oceanology, and has spent his life studying the deep ocean - and in...
