TL;DR: In this paper, the authors evaluated temperature and precipitation extremes and their potential future changes in an ensemble of global coupled climate models participating in the Intergovernmental Panel on Climate Change (IPCC) diagnostic exercise for the Fourth Assessment Report (AR4).

TL;DR: It is shown that anthropogenic forcing has had a detectable influence on observed changes in average precipitation within latitudinal bands, and that these changes cannot be explained by internal climate variability or natural forcing.

TL;DR: These guidance notes are intended to assist the Lead Authors of the Fifth Assessment Report (AR5) in the consistent treatment of uncertainties across all three Working Groups as discussed by the authors, which can be used broadly for developing expert judgments and for evaluating and communicating the degree of certainty in findings of the assessment process.

TL;DR: A review of late-Holocene palaeoclimaoclimatology represents the results from a PAGES/CLIVAR Intersection Panel meeting that took place in June 2006 as mentioned in this paper, emphasizing current issues in their use for climate reconstruction; various approaches that have been adopted to combine multiple climate proxy records to provide estimates of past annual-to-decadal timescale Northern Hemisphere surface temperatures and other climate variables, such as large-scale circulation indices; and the forcing histories used in climate model simulations of the past millennium.

TL;DR: In this article, a number of climate models representing possible future climate states have been used to predict weather and climate extremes, such as a greater frequency of extreme warm days and lower frequency of extremely cold days associated with a warmer mean climate, a decrease in diurnal temperature range associated with higher nighttime temperatures, increased precipitation intensity, midcontinent summer drying, decreasing daily variability of surface temperature in winter, and increasing variability of northern midlatitude summer surface temperatures.
