The present interglacial, the Holocene, spans the period of the last 11,700 years. It has
sustained the growth and development of modern society. The millennial-scale decreasing …

A prominent, abrupt climate event about 8200 years ago brought generally cold and dry
conditions to broad northern-hemisphere regions especially in wintertime, in response to a …

2 Chapter 2 assesses observed large-scale changes in climate system drivers, key climate
indicators and 3 principal modes of variability. Chapter 3 considers model performance and …

We consider the long-term relationship between human demography, food production, and
Holocene climate via an archaeological radiocarbon date series of unprecedented sampling …

• The sustained rate of increase over the past century in the combined radiative forcing from
the three well-mixed greenhouse gases carbon dioxide (CO2), methane (CH4), and nitrous …

The threat of future global warming has generated a major interest in quantifying past
climate variability on centennial and millennial time-scales. However, palaeoclimatological …

The Atlantic meridional overturning circulation (AMOC) transports warm salty surface waters
to high latitudes, where they cool, sink and return southwards at depth. Through its attendant …

We review and synthesize the geologic record that constrains the sources of sea level rise
and freshwater discharge to the global oceans associated with retreat of ice sheets during …

Evidence from a North Atlantic deep-sea sediment core reveals that the largest climatic
perturbation in our present interglacial, the 8200-year event, is marked by two distinct …

A mean continental July temperature reconstruction based on pollen records from across
North America quantifies temperature variations of several timescales for the past 14,000 cal …
