"In the Goddard Institute for Space Studies (GISS) climate model, when global warming due to higher CO2 levels was sufficiently advanced, and the effect of aerosols on cloud cover included, the North Atlantic overturning ocean circulation shuts down. It stayed off for about 1,000 years and then suddenly resumed."

Economic, environmental, and social performance indicators of sustainability reporting: Evidence from the Russian oil and gas industry

"The findings suggest that companies with a share of foreign ownership disclose more transparent sustainability information than companies owned only by local investors. Additionally, companies that prepare sustainability reports only in Russian provide more valuable sustainability information than companies that publish reports in both English and Russian."

Palaeoclimatology

On the mechanisms of warming the mid-Pliocene and the inference of a hierarchy of climate sensitivities with relevance to the understanding of climate futures (open access)

"We find that two-thirds of the warming pervasive during the mid-Pliocene, compared to the preindustrial, could be attributed to the reduction in the planetary emissivity owing to the higher concentrations of the greenhouse gases CO₂ and water vapor, and the remaining one-third to the reduction in planetary albedo. We also find that changes to the orography and the pCO₂ are the leading causes of the warming with each contributing in roughly equal parts to a total of 87?% of the warming and changes to the polar ice sheets responsible for the remaining warming." ... "on the short timescale, owing to the influence of fast feedback processes, the climate sensitivity is 3.25?°C per doubling of CO₂; sensitivity increases to 4.16?°C per doubling of CO₂ on an intermediate timescale as the ice–albedo feedback becomes active, and then sensitivity further increases to 7.0?°C per doubling of CO₂ on long timescales due to the feedback from the glacial isostatic adjustment of the Earth's surface in response to the melting of the polar ice sheets. Finally, once the slow feedbacks have stabilized, the sensitivity of the system drops to 3.35?°C per doubling of CO₂."

Large-scale, millennial-length temperature reconstructions from tree-rings

"Whereas the reconstructions agree on several important features, such as warmth during medieval times and cooler temperatures in the 17th and 19th centuries, they still exhibit substantial differences during 13th and 14th centuries. We caution users who might consider combining the reconstructions through simple averaging that all reconstructions share some of the same underlying tree-ring data, and provide four recommendations to guide future efforts to better understand past millennium temperature variability."
