Short summary
Long-term climate change impacts on fire, vegetation and permafrost in the Arctic are uncertain. Here, we show the high potential of organic compounds from low-temperature biomass burning to serve as proxies for surface fires in lake deposits. During warm periods of the last 430 000 years, surface fires are closely linked to the larch taiga forest with its moss–lichen ground vegetation that isolates the permafrost. They have reduced in warm–wet, spruce–dominated and cool–dry steppe environments.

We present a new detailed pollen and isotope record from Lake Van (Turkey) spanning the period from 250 to 128 ka. In contrast to SW Europe, all three terrestrial warm intervals at Lake Van are characterized by clear interglacial conditions. The largest forest expansion occurred during MIS 7c instead of MIS 7e. Our record also reveals high oscillations between 193 and 157 ka followed by low variations (157 to 131 ka) that highlighted Dansgaard–Oeschger-like events during the penultimate glacial.

We compare eight pollen records reflecting environmental change in the tropical Andes over the past 30 000 years. Our analysis focuses on the signature of millennial-scale climate variability in the tropical Andes: Heinrich stadials (HS) and Greenland interstadials (GI). We identify rapid responses of the tropical vegetation, with downslope upper forest line (UFL) migrations and cooling during HS and the Younger Dryas.

We analyze the vegetation and climate in northwestern Turkey during the last ca. 31 000 years based on a new pollen data set from lacustrine sediment cores. The study reveals vegetation responses to long-term and rapid climate changes. Moreover, it documents human activities in the catchment of Lake Iznik and shows a clear anthropogenic impact on the vegetation since the Early Bronze Age.

We present a review of chronological dating from ca. 1100 fossil pollen records in Central and South America. Additionally, a temporal quality assessment is implemented on 292 records from northwest South America, which include recalibrating 234 age models. This method evaluates uncertainties for inferred sample ages and chronologies. Important time windows on centennial-millennial climate variability are discussed for sample resolution (estimated years/sample) and temporal uncertainty.
