Environmental Geology

Few of us have any conception of the enormous timescales in our planet's long history, and this narrow perspective underlies many of the environmental problems we are creating for ourselves. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future.

Spanning millennia and continents, here is a stunningly revealing history of how the distribution of water has shaped human civilization. Giulio Boc­caletti - honorary research associate at the Smith School of Enterprise and the Environment, Univer­sity of Oxford - shrewdly combines environmental and social history, beginning with the earliest civ­ilizations of sedentary farmers on the banks of the Nile, the Tigris, and the Euphrates Rivers.

In 2018, lumps of frozen soil, collected from the bottom of the world's first deep ice core and lost for decades, reappeared in Denmark. When geologist Paul Bierman and his team first melted a piece of this unique material, they were shocked to find perfectly preserved leaves, twigs, and moss. That observation led them to a startling discovery: Greenland's ice sheet had melted naturally before, about 400,000 years ago.

Four-and-a-half billion years ago, Planet Earth was formed from a vast spinning nebula of cosmic dust, the detritus left over from the birth of the sun. Within the next 100 years, human life on swathes of the Earth's surface will end in a haze of heat, drought, and, again, dust. Dust is a legacy of 20th-century progress and a profound threat to life in the 21st century. And yet dust is something we hardly ever consider--it is so small and so mundane as to be beyond the threshold of thought. Jay Owen's Dust sparks curiosity and corrects that oversight.

Masterfully tying together history, science, and human drama, The Lost Dinosaurs of Egypt is the gripping account of two of the 20th century's great expeditions of discovery. In 1911 a German paleontologist found the remains of four entirely new dinosaurs in the Egyptian desert, but in a single night, all of his work was destroyed. Eighty-nine years later, an American grad student leads an expedition to unearth Stromer's dinosaur graveyard, and in doing so, he stuns the scientific world.
