Climate change is altering the seasonal accumulation and ablation of snow across mid-
latitude mountainous regions in the Northern Hemisphere with profound implications for the …

Recent studies of snow climatology show a mix of trends but a preponderance of evidence
suggest an overall tendency toward decreases in several metrics of snow extremes. The …

2 Chapter 2 assesses observed large-scale changes in climate system drivers, key climate
indicators and 3 principal modes of variability. Chapter 3 considers model performance and …

The AR5 concluded that human influence on the climate system is clear, evident from
increasing greenhouse gas concentrations in the atmosphere, positive radiative forcing …

This chapter assesses the causes of observed changes assessed in Chapters 2 to 5 and
uses understanding of physical processes, climate models and statistical approaches. The …

The first issue of WRR appeared eight years after the launch of Sputnik, but by WRR's 25th
anniversary, only seven papers that used remote sensing had appeared. Over the journal's …

The last few years have seen an explosion of interest in extreme event attribution, the
science of estimating the influence of human activities or other factors on the probability and …

Notwithstanding the large availability of data and models, a consistent picture of the snow
cover extent and duration changes in global mountain areas is lacking for long-term trends …

The global climate continues to change rapidly compared to the pace of the natural
variations in climate that have occurred throughout Earth's history. Trends in globally …

Seasonal snow is a critical component of the surface energy balance and hydrologic cycle,
yet global maps of seasonal snow boundaries are not readily available. Snow persistence …
