Abrupt climate change in the computer: is it real?
نویسندگان
چکیده
Models suggest that dramatic changes in the ocean circulation are responsible for abrupt climate changes during the last ice age and may possibly alter the relative climate stability of the last 10,000 years.

Interactive comment on “Transition process of abrupt climate change based on global sea surface temperature over the past century” by Pengcheng Yan et al
relatively standard. Thus, when an abrupt change in one grid is detected, it means that the difference between the two states before and after the abrupt change of this moment has the biggest amplitude by comparing with the other moment. Taking fig. A3 for example, we know that both the two series have two abrupt changes in moment t1 and t2 respectively. However, when we detect the abrupt chang...
متن کاملمدلسازی اثر تغییر اقلیم بر انتشار دی‌اکسیدکربن خاک در مراتع خشک (جنوب ایران)
Introduction: Carbon stored in soils particularly in arid rangelands soils is the most significant carbon sink in terrestrial ecosystems. In arid rangelands, Soils have special places in both carbon sequestration and mitigate global warming. Therefore, any small change in the soil organic carbon (SOC) leads to a significant impact on the CO2 concentration in the atmosphere. Studies have shown t...
متن کاملEvaluation of Climate Change Impacts on Hydrological Characteristics of Watershed (Case study: Aji- Chai Watershed)
Studying climate change impact on hydrological variables such as runoff has attracted more attention over recent years mainly due to the imposed imbalance in climate system by greenhouse gas emission. Hence, initially in this research, the trend and abrupt changes of hydro – climatic variables were studied using data mining approaches in 18 stations over 40 years (1972-2011) in Aji-Chai waters...
متن کاملAbrupt climate change.
Large, abrupt, and widespread climate changes with major impacts have occurred repeatedly in the past, when the Earth system was forced across thresholds. Although abrupt climate changes can occur for many reasons, it is conceivable that human forcing of climate change is increasing the probability of large, abrupt events. Were such an event to recur, the economic and ecological impacts could b...
متن کاملClimate Change Impact on Precipitation Extreme Events in Uncertainty Situation; Passing from Global Scale to Regional Scale
Global warming and then climate change are important topics studied by researchers throughout the world in the recent decades. In these studies, climatic parameters changes are investigated. Considering large-scaled output of AOGCMs and low precision in computational cells, uncertainty analysis is one of the principles in doing hydrological studies. For this reason, it is tried that investigati...
