Palaeoclimate constraints on the impact of 2 C anthropogenic warming and beyond
Over the past 3.5 million years, there have been several intervals when climate conditions
were warmer than during the pre-industrial Holocene. Although past intervals of warming …

[HTML][HTML] Evolution of the Laurentide and Innuitian ice sheets prior to the Last Glacial Maximum (115 ka to 25 ka)
Abstract The Laurentide Ice Sheet was the largest global ice mass to grow and decay during
the last glacial cycle (~ 115 ka to~ 10 ka). Despite its importance for driving major changes …

A global environmental crisis 42,000 years ago
Geological archives record multiple reversals of Earth's magnetic poles, but the global
impacts of these events, if any, remain unclear. Uncertain radiocarbon calibration has limited …

A new global ice sheet reconstruction for the past 80 000 years
The evolution of past global ice sheets is highly uncertain. One example is the missing ice

The timing and effect of the earliest human arrivals in North America
The peopling of the Americas marks a major expansion of humans across the planet.
However, questions regarding the timing and mechanisms of this dispersal remain, and the …

Sea-level records from the US mid-Atlantic constrain Laurentide Ice Sheet extent during Marine Isotope Stage 3
The US mid-Atlantic sea-level record is sensitive to the history of the Laurentide Ice Sheet as
the coastline lies along the ice sheet's peripheral bulge. However, paleo sea-level markers …

The marine δ18O record overestimates continental ice volume during Marine Isotope Stage 3
There is disagreement in the Quaternary research community in how much of the marine δ
18 O signal is driven by change in ice volume. Here, we examine this topic by bringing …
