Heat is the first order threat that drives all other impacts of the climate crisis. And as the temperature rises, it is revealing fault lines in our governments, our politics, our economy, and our values. The basic science is not complicated: Stop burning fossil fuels tomorrow, and the global temperature will stop rising tomorrow.

Grim Reaper sits on the heart surgeon's shoulder. A slip of the hand and life ebbs away. The balance between life and death is so delicate, and the heart surgeon walks that rope between the two. In the operating room, there is no time for doubt. It is flesh, blood, rib retractors and pumping the vital organ with your bare hand to squeeze the life back into it. An off day can have dire consequences - this job has a steep learning curve, and the cost is measured in human life. Cardiac surgery is not for the faint of heart.

At the center of the controversy was Dr. Andrew Loveridge, the zoologist who had studied Cecil for eight years. In Lion Hearted, Loveridge pieces together, for the first time, the fascinating life and murky details of this beloved lion’s slaying.

Imagine a world without natural light, where you can barely stand up straight for fear of knocking your head, where you have no idea of where in the world you are or what time of day it is, where you sleep in a coffin-size bunk and sometimes eat a full roast for breakfast. Now imagine sharing that world with 140 other sweaty bodies, crammed into a 430ft x 33ft steel tube, 300ft underwater, for up to 90 days at a time, with no possibility of escape.

The grizzly is one of North America's few remaining large predators. Their range is diminished, but they're spreading across the West again. Descending into valleys where once they were king, bears find the landscape they'd known for eons utterly changed by the new most dominant animal: humans. In searing detail, award-winning writer, Montana rancher, and conservationist Bryce Andrews tells us about one such grizzly. Millie is a typical mother: strong, cunning, fiercely protective of her cubs. But raising those cubs becomes ever harder as the climate warms and people crowd the valleys.
