The dry and windy Asian glacials during the mid-Pleistocene transition were probably due to the Northern Hemisphere ice sheet expansion, suggest records of grain size and magnetic susceptibility from the Chinese Loess Plateau and model simulations.

The fastest sea-ice decline has been observed in the western Arctic, but the underlying mechanisms are still unclear. Here, the authors show that the Pacific North American pattern plays an important role in western Arctic sea-ice variability.

Marine records indicate a greenhouse to icehouse climate transition at ~34 million years ago, but how the climate changed within continental interiors at this time is less well known. Here, the authors show an orbital climate response shift with arid

Amplification of heat extremes by plant CO2 physiological forcing

Autor: Christopher B. Skinner, Christopher J. Poulsen, Justin S. Mankin

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-11 (2018)

The effect of plants on future extreme heat events under elevated carbon dioxide (CO2) is unclear. Here, the authors show that CO2 plant physiological effects lead to increases in heat waves within a suite of climate model simulations, suggesting tha

The last two decades have seen a dramatic decline and strong year-to-year variability in Arctic winter sea ice, especially in the Barents-Kara Sea (BKS), changes that have been linked to extreme midlatitude weather and climate. It has been suggested
