The 15th century Arctic warming in coupled model simulations with data assimilation
Arctic warming dimensional climate model data assimilation
2009/12/3
An ensemble of simulations of the climate of the past millennium conducted with a three-dimensional climate model of intermediate complexity are constrained to follow temperature histories obtained f...
The warming trend of the last decades is now so strong that it is discernible in local temperature observations. This opens the possibility to compare the trend to the warming predicted by comprehen...
UChicago climate scientists share concerns about global warming at EPA hearings
UChicago climate scientists global warming EPA hearings
2009/12/8
Two University of Chicago scientists last week appeared at EPA hearings in Rosemont, Ill., to offer support for proposed new regulations on carbon-dioxide emissions from large power plants.The comment...
Explicit calculation of indirect global warming potentials for halons using atmospheric models
Explicit calculation halons atmospheric models
2009/11/19
The concept of Global Warming Potentials (GWPs) has been extensively used in policy consideration as a relative index for comparing the climate impact of an emitted greenhouse gas (GHG), relative to c...
Disrupted seasonal clockwork in the population dynamics of a freshwater copepod by climate warming
Disrupted seasonal clockwork the population dynamics freshwater copepod climate warming
2014/4/17
Life history responses are expected to accompany climate warming, yet little is known how long-term effects of climate and environmental change affect the seasonal dynamics of planktonic organisms. We...
The physics of the warming of Lake Tanganyika by climate change
The physics of the warming Lake Tanganyika climate change
2014/4/17
Climate warming over the 20th century has increased the density stratification and stability of Lake Tanganyika, a deep rift valley lake. Here we examine the physical processes involved in and affecte...

2009/8/28
By using the summer torrential rain days data in Ningxia, the Yinchuan sounding data and the NCEP/NCAR reanalyzed data, the evolutional characteristics and the cause of torrential rain days in Ningxia...
Railway Construction Techniques Adapting to Climate Warming in Permafrost Regions
Qinghai-Tibet Railway climate warming railway construction
2009/8/28
The climate warming, which has an evident effect on the warm/ice-rich permafrost, should be considered in the engineering design of the Qinghai-Tibet Railway in permafrost areas. Based on the rule men...
Low-level clouds are involved in a positive feedback mechanism that could exacerbate global warming — according to a study of cloud and temperature records from the north-eastern Pacific Ocean. Scient...
Satellite observations and modeling of transport in the upper troposphere through the lower mesosphere during the 2006 major stratospheric sudden warming
Satellite observations upper troposphere lower mesosphere major stratospheric sudden warming
2009/7/23
An unusually strong and prolonged stratospheric sudden warming (SSW) in January 2006 was the first major SSW for which globally distributed long-lived trace gas data are available covering the upper t...
Stratospheric warming in Southern Hemisphere high latitudes since 1979
Stratospheric warming Southern Hemisphere high latitudes
2009/7/15
In the present study, we show evidence of significant stratospheric warming over Southern Hemisphere high latitudes and large portions of the Antarctic polar region in winter and spring seasons, with ...
New findings predict that global temperature increases will be twice as high by the end of the century as previously forecast, unless international policy action is taken. That is the prediction of sc...
Climate change odds much worse than thought-New analysis shows warming could be double previous estimates

The study uses the MIT Integrated Global Systems Model, a detailed computer simulation of global economic activity and climate processes that has been developed and refined by the Joint Program on the...
Springtime warming and reduced snow cover from carbonaceous particles
Springtime warming snow carbonaceous particles
2009/5/7
Boreal spring climate is uniquely susceptible to solar warming mechanisms because it has expansive snow cover and receives relatively strong insolation. Carbonaceous particles can influence snow cover...
