TL;DR: In this article, the authors present some indications from observations concerning how climatic extremes may have changed in the past and how they could change in the future either due to natural climate fluctuations or under conditions of greenhouse gas-induced warming.

TL;DR: The state of knowledge regarding trends and an understanding of their causes for a specific subset of extreme weather and climate types is presented in this paper for severe convective storms (tornadoes, hailstorms, and severe thunderstorms).

TL;DR: This paper found that most of the upward trends found in financial losses are due to societal shifts leading to ever growing vulnerability to weather and climate extremes, and geographic locations of the large loss trends establish that population growth and demographic shifts are the major factors behind the increasing losses from weather-climate extremes.

TL;DR: This paper found that the largest increases in storms occurred in areas experiencing the greatest population growth (west, southwest, south, and southeast) and that shifts in atmospheric variables (particularly in the frequency of extratropical cyclones) explained most of the 1949-94 fluctuations found in the intensity of catastrophic storms (losses divided by storm frequency).

TL;DR: In this article, a 100-year period, 1896-1995, derived from carefully screened records of 66 first-order stations distributed across the United States, were assessed for temporal fluctuations and trends.
