Short summary
Ice drilled from deep inside Antarctica reveals how climate changed over hundreds of thousands of years. However, the ice sheet itself rises and sinks over time, which can distort temperatures read from the ice. Using three computer simulations covering the last two million years, we show that drilling sites rose and sank by up to 240 metres and their summits shifted by up to 120 kilometres, and we estimate how this biases climate records, including potential for the oldest ice.

A new 10-member ensemble simulation with the state-of-the-art Earth system model was employed to study the long-term climate response to sustained greenhouse warming through to the year 2500. The findings show that the projected changes in the forced mean state and internal variability during 2101–2500 differ substantially from the 21st-century projections, emphasizing the importance of multi-century perspectives for understanding future climate change and informing effective mitigation strategies.

Based on a series of storm-resolving greenhouse warming simulations conducted with the AWI-CM3 model at 9 km global atmosphere and 4–25 km ocean resolution, we present new projections of regional climate change, modes of climate variability, and extreme events. The 10-year-long high-resolution simulations for the 2000s, 2030s, 2060s, and 2090s were initialized from a coarser-resolution transient run (31 km atmosphere) which follows the SSP5-8.5 greenhouse gas emission scenario from 1950–2100 CE.

To quantify the sensitivity of the earth system to orbital-scale forcings, we conducted an unprecedented quasi-continuous coupled general climate model simulation with the Community Earth System Model, which covers the climatic history of the past 3 million years. This study could stimulate future transient paleo-climate model simulations and perspectives to further highlight and document the effect of anthropogenic CO2 emissions in the broader paleo-climatic context.

Short summary
A large ensemble of simulations with 100 members has been conducted with the state-of-the-art CESM2 Earth system model, using historical and SSP3-7.0 forcing. Our main finding is that there are significant changes in the variance of the Earth system in response to anthropogenic forcing, with these changes spanning a broad range of variables important to impacts for human populations and ecosystems.

Short summary
A longstanding conundrum regarding the stable oxygen isotope (δ18O) proxy for hydroclimate in speleothems from the Korean Peninsula, which, unlike records from East Asia (e.g., China), do not exhibit isotopic shifts in response to precession forcing. Using Korean speleothem records spanning several orbital-scale segments of the last ~550,000 years and paleoclimate simulations, the present study proposes a plausible role of the oceanic and continental moisture mixing in suppressing δ18O signals.
