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.

The volcano - among the most familiar and perhaps the most terrifying of all geological phenomena. However, Earth isn't the only planet to harbour volcanoes. In fact, the solar system, and probably the entire universe, is littered with them. Our own Moon, which is now a dormant piece of rock, had lava flowing across its surface billions of years ago, while Mars can be credited with the largest volcano in the solar system.

More than half a billion years ago, our world was completely covered by glaciers, a "Snowball Earth" that persisted for millions of years. Incredibly, this unimaginable cold led to the remarkable diversification of life on earth known as the Cambrian explosion. With a geologist's eye and a knack for storytelling, Graham Shields explores when and how such inhospitable conditions enabled animals to evolve, radiate, and diversify into our earliest ancestors.

Every year, droughts, floods, and fires impact hundreds of millions of people and cause massive economic losses. Climate change is making these catastrophes more dangerous. Now. Not in the future: now. This book describes how and why climate change is already fomenting dire consequences and will certainly make climate disasters worse in the near future.

Raging wildfires have devastated vast areas of California and Australia in recent years, and predictions are that we will see more of the same in coming years as a result of climate change. But this is nothing new. Andrew C. Scott tells the whole story of fire's impact on our planet's atmosphere, climate, vegetation, ecology, and the evolution of plant and animal life. It has caused mass extinctions, and it has propelled the spread of flowering plants. The exciting evidence we can now draw on has been preserved in fossilized charcoal, found in rocks hundreds of millions of years old....

Wildfire is a major ecological issue, especially in the Western United States. On the Living With Fire podcast, you'll hear perspectives and stories from land managers, scientists, fire professionals and community members about the history of fire, how fire is currently managed in the landscape and the role that humans play in living more safely with wildfire. This podcast was funded by the Bureau of Land Management - Nevada State Office. The Living With Fire Program is a multiagency effort and is managed by the University of Nevada, Reno Extension. An EEO/AA institution.

Iceland's Volcanic Unrest: Is it A Cause for Concern? Iceland, a land of fire and ice, is no stranger to volcanic activity. With around 30 active volcanic systems, the country experiences an eruption on average every five years. However, recent volcanic disturbances in the Reykjanes Peninsula, southwest of Iceland's capital, Reykjavík, have raised concerns among locals and tourists alike. Since late March 2021, the Reykjanes Peninsula has experienced a significant increase in seismic activity. Thousands of earthquakes, some reaching magnitudes of 5 or higher, have rattled the region. This ...
