TLDR
In this article, the authors show that decadal variations in the number of U.S. heat and cold waves do not correlate well with the observed global warming during the last century, and the analysis of trends in river flooding is multiyear and even multidecadal variability likely caused by both large-scale atmospheric circulation changes and basin-scale "memory" in the form of soil moisture.Abstract:
Weather and climate extremes have been varying and changing on many different time scales. In recent decades, heat waves have generally become more frequent across the United States, while cold waves have been decreasing. While this is in keeping with expectations in a warming climate, it turns out that decadal variations in the number of U.S. heat and cold waves do not correlate well with the observed U.S. warming during the last century. Annual peak flow data reveal that river flooding trends on the century scale do not show uniform changes across the country. While flood magnitudes in the Southwest have been decreasing, flood magnitudes in the Northeast and north-central United States have been increasing. Confounding the analysis of trends in river flooding is multiyear and even multidecadal variability likely caused by both large-scale atmospheric circulation changes and basin-scale “memory” in the form of soil moisture. Droughts also have long-term trends as well as multiyear and decadal variability...read more

TL;DR: Using a range of ocean temperature data including global records of daily satellite observations, daily in situ measurements and gridded monthly in situ-based data sets, this work identifies significant increases in marine heatwaves over the past century.

Changes in Ecologically Critical Terrestrial Climate Conditions
TL;DR: The likelihood of continued changes in terrestrial climate is reviewed, including analyses of the Coupled Model Intercomparison Project global climate model ensemble, to create potential 21st-century global warming comparable in magnitude to that of the largest global changes in the past 65 million years but is orders of magnitude more rapid.

A review on the scientific understanding of heatwaves—Their measurement, driving mechanisms, and changes at the global scale
TL;DR: In this paper, the authors present a review of the recent advances in the scientific understanding of heatwaves, including how heatwaves are measured, their driving mechanisms, observed and projected changes, and quantifying the anthropogenic influence behind these changes.

TL;DR: The results suggest that scientifically durable operational attribution is possible but they also highlight the importance of carefully diagnosing and testing the physical causes of individual events.

TL;DR: There is evidence of within-species genetic variation in thermal tolerance, which could be important to exploit in production forestry systems and critically important for understanding how tree species will be affected by climate change.

TL;DR: The first volume of the IPCC's Fourth Assessment Report as mentioned in this paper was published in 2007 and covers several topics including the extensive range of observations now available for the atmosphere and surface, changes in sea level, assesses the paleoclimatic perspective, climate change causes both natural and anthropogenic, and climate models for projections of global climate.

TL;DR: A review of the ecological impacts of recent climate change exposes a coherent pattern of ecological change across systems, from polar terrestrial to tropical marine environments.
The relationship of drought frequency and duration to time scales
TL;DR: The definition of drought has continually been a stumbling block for drought monitoring and analysis as mentioned in this paper, mainly related to the time period over which deficits accumulate and to the connection of the deficit in precipitation to deficits in usable water sources and the impacts that ensue.

An Introduction to Statistical Modeling of Extreme Values
TL;DR: This paper presents a meta-modelling framework that automates the very labor-intensive and therefore time-heavy and therefore expensive and expensive process of manually cataloging and modeling extreme value values in sequences.
