Summary: The 2022 Indian heatwave had a significant impact on wheat production in northwestern and central India, resulting in an expected 4.5% decrease in national wheat production. Through the use of historical data and statistical relationships, we provided spatially disaggregated estimates of wheat yield losses, demonstrating the feasibility of using real-time weather data to estimate end-of-season crop yields.

Summary: The study found that there were 1921 additional deaths during the 2020 heatwaves in France, the highest number since 2003, with less than 100 deaths attributed to COVID-19. The exceptionally high temperatures driven by climate change, combined with health inequities exacerbated by the COVID-19 outbreak, may have increased vulnerability to heat in 2020.

Summary: This study evaluates different methods to quantify extreme heat in New Zealand and discusses further research priorities to better understand the impacts of extreme heat in New Zealand over the coming decades. It introduces a new method of quantifying extreme heat, detects previously unidentified heatwaves, and identifies locally significant increases in extreme heat and the potential lengthening of summer months after only 0.5 degrees C of global warming.

Summary: Adaptation is crucial in reducing the social burden caused by heatwaves, but our understanding of adaptation capacity across different socioeconomic levels is incomplete. Observed heatwave trends in the past four decades have been most significant in the poorest regions, resulting in over 40% higher exposure from 2010 to 2019 compared to the richest regions. Lower-income regions have reduced adaptative capacity to warming, which amplifies the impacts of higher heatwave exposure. In addition, contiguous heatwaves have engulfed larger areas in recent years compared to the 1980s. Widespread heatwaves can overwhelm the power grid and nullify electricity-dependent adaptation efforts, even in regions with higher adaptation capacity.

Summary: This study develops a probabilistic framework to explore heatwave events and applies it to climate change research in Iran. The results show a significant increase in heatwave hazard across Iran, with shorter heatwaves being more intensified.

Summary: Persistent heat extremes in Europe have severe impacts on ecosystems and societies, and the heatwave trends in Europe have been accelerating compared to other regions. The increase in the persistence of double jet events over Eurasia is found to be a major driver of this acceleration. These findings have important implications for risk management and potential adaptation strategies.

Summary: Citizens in many countries are currently experiencing record-breaking heatwaves that have been exacerbated by anthropogenic climate change. The question of whether similar heatwaves could have occurred in pre-industrial climates, which was traditionally a central focus of attribution research, is becoming increasingly irrelevant. The next frontier for attribution science is to provide information for adaptation decision-making in the face of unprecedented future heat.

Summary: The study reveals that the 2021 heatwave in the Pacific Northwest was extremely rare, occurring with a frequency of approximately one in a hundred thousand years. Although historical data does not indicate a faster warming rate in the upper tail of temperature compared to the mean, future projections show a significant positive trend in the probability of the most extreme events for locations with similar climatological characteristics.

Summary: In this study, the researchers examine the impacts of ocean warming on the growth, metabolic rate, and gene expression of clownfish larvae. They find that larvae reared at higher temperatures grow and develop faster, exhibit higher metabolic rates, and have differential gene expression. These results indicate that future warming could alter clownfish development and have implications for larval dispersal and settlement time.

Summary: Compounded weather events such as sequential heatwaves are likely to have an increasing impact on freshwater ecosystems, especially lakes. During a double heatwave event in 2019, deep and medium depth lakes in higher latitudes showed a synchronous increase in chlorophyll-a concentration with temperature, while shallow lakes displayed a less synchronous response.

Summary: Heatwaves are a significant cause of climate-related deaths. The communication of health risks based solely on temperature maps may not provide an accurate perception of danger. Recent heatwaves in Europe, the United States, and Asia showed variations in peak values of temperature and heat stress indices, indicating the need to reevaluate how these events are communicated. Collaboration between climate and medical communities is necessary to develop and implement effective heat stress indicators for public awareness.

Summary: Extreme weather events are occurring at a faster rate than expected, changing our understanding of the climate system and climate change issues. While some changes can be attributed to rising greenhouse gas emissions, further research is needed to explain other counterintuitive changes.

Summary: A record-breaking heatwave hit a large area including parts of Argentina, Bolivia, Chile, Paraguay, and Uruguay in late November and early December 2022. The heatwave was influenced by human-caused climate change, which made it about 60 times more likely. The early summer heatwaves pose a significant risk to human health and highlight the importance of attribution studies in a region vulnerable to climate change.

Summary: This study analyzes the impact of global warming on the upper extremes of daily temperatures in Spain. It proposes the use of record tests to compare the occurrence of extreme events in observed series and a stationary climate. The results show significant evidence of increasing occurrence of upper extremes in most regions of Spain, with seasonal and spatial variations.
