The analysis of mercury isotopes deposited from #seabird guano into #peatlands serves as a continuous geochemical proxy to reconstruct ancient seabird population dynamics and correlate them with historical climatic shifts over millennia.

During the Late Miocene epoch, massive volcanic eruptions in the Andes deposited nutrient-rich ash into the Southern Ocean, triggering widespread marine algae blooms that simultaneously fueled the evolution of gigantic whales, caused localized mass mortality events, and significantly cooled the Earth by drawing atmospheric carbon dioxide into the sea.

Analysis of a 16-meter sediment core from Lake Yoa in Chad reveals that the "African Humid Period" (14,800 to 5,500 years ago) was not a continuously wet era, but was instead abruptly interrupted by severe, decadal-scale droughts.

The 40,000-year obliquity cycle tied to Earth's axial tilt, which dictated the growth and decay of the Antarctic ice sheet 34 million years ago, directly drove marine biological productivity in the distant subtropical ocean.

#Peatlands in the #Magdalen Islands preserve a 4,000-year record of Atlantic storm activity, revealing that the region's recent surge in intense #hurricanes aligns with historical cycles of heightened storminess rather than being a strictly modern phenomenon.

Atmospheric Science is the comprehensive study of the Earth's atmosphere, its physical and chemical processes, and the interactions between the atmosphere and other systems such as the hydrosphere, lithosphere, and biosphere.

Paleoclimatology is the scientific study of climates in the geologic past. It aims to reconstruct Earth’s climate history to understand how and why #climate changes over long periods, using data preserved in natural records such as ice cores, tree rings, sediment, and fossils to provide context for current and future climate trends.

Ancestors of key #crops like wheat, barley, and rye were significantly less widespread in the Middle East 12,000 years ago than previously believed, surviving primarily in a "refugium" along the Mediterranean coast of the Levant.
