For the first time in 24 years, this report comprehensively summarizes the status — population size and population trends — of Antarctica’s five penguin species, continent-wide and in key regions. These species total at least 5.7 million breeding pairs nesting at 660 or more sites across the entire Antarctic continent.

Noteworthy extreme events in 2016 included severe droughts that brought food insecurity to millions in southern and eastern Africa and Central America.
Meteorological studies have indicated that high alpine environments are strongly affected by climate warming, and periglacial debris flows are frequent in deglaciated regions. The combination of rainfall and air temperature controls the initiation of periglacial debris flows, and the addition of meltwater due to higher air temperatures enhances the complexity of the triggering mechanism compared to that of storm-induced debris flows.
This report provides regional sea-level rise scenarios and tools for coastal preparedness planning and risk management in the United States. It refines six global sea level rise scenarios (Low, Intermediate Low, Intermediate, Intermediate High, High, and Extreme) decade by decade.
