The Holocene Conundrum - PUFINS at Sea

What Is Climate Change? - NASA Science

For decades, the Holocene was treated as climatically calm, stable enough to ignore in historical models. By the 1960s, the evidence said otherwise. Climate shifted repeatedly over the last 10,000 years, forcing researchers to rethink how deeply weather and environment shaped human history. | The Randall Carlson

Causes - NASA Science

Contrary to modern assumptions, the Holocene—the last 10,000 years—was not a time of steady climate. Hubert Lamb identified four major climate epochs: 1️⃣ The Postglacial Optimum 2️⃣ The Iron Age Cold Period 3️⃣ The Medieval Warm Period 4️⃣ The Little Ice Age Even the Arctic Ocean may have been ice-free in summer. The past wasn’t stable. So why assume the present is? | The Randall Carlson

Earth’s five mass extinctions

🔹 Climate Change “There have been five major extinctions during the life of planet Earth; the Ordovician, Devonian, Permian, Triassic, and the Cretaceous. All previous extinctions were due to climate change, the cooling of the oceans, the eradication of sunlight from volcanic eruption, or asteroid impact. A majority of scientists now believe that we are well into the sixth mass extinction (Holocene) on Earth. However, the current cycle is due entirely to human impact upon the planet and is happ
