Map showing the physical imprint and consequences of extreme summer heat across the Pacific Northwest in 2021. The June-August (JJA) 2021 seasonally averaged temperature anomalies (t2m) over North America calculated from the 1951-1980 mean of ERA5 Reanalysis, with the Pacific Northwest region (PNW; 42–53 °N, 124–115 °W, dark blue box) highlighted. The year 2021 (dashed black line) is shown relative to the distribution (black line) and probability density (red line) curves of JJA t2m values over the period 1950–2021 for the PNW region. White exes indicate the locations of all tree-ring chronology predictors used in the subsequent JJA t2m reconstruction. Graphic: Heeter, et al., 2023 / npj Climate and Atmospheric Science

The summer of 2021 was the Pacific Northwest’s hottest in a millennium – “The tree scorch was shocking. The average summer temperatures were extraordinarily away from the norm.”

By Sid Perkins 14 April 2023 (Science News) – A two-week-long heat wave in the Pacific Northwest in 2021 helped make that summer a record breaker for the region (SN: 7/7/21). Now, tree ring data from the area’s forests reveal that the summer of 2021 was also the region’s hottest of the last millennium. The average temperature […]

The surface of the ocean is now so hot it’s broken every record since satellite measurements began

By Stephanie Pappas 14 April 2023 (Live Science) – Ocean surface temperatures have hit an all-time high this month, breaking every record since satellite measurements began in the 1980s. Temperatures reached a global average of 69.98 Fahrenheit (21.1 degrees Celsius) in the first days of April. The previous record of 69.9 F (21 degrees C) […]

Munich Re: Climate change and La Niña driving losses – “Climate change is taking an increasing toll. The natural disaster figures for 2022 are dominated by events that, according to the latest research findings, are more intense or are occurring more frequently.”

10 January 2023 (Munich Re) – With overall losses of around US$ 270bn (previous year US$ 320bn) and insured losses of roughly US$ 120bn (previous year US$ 120bn), 2022 joins the recent run of years with high losses. Overall losses were close to the average for the last five years, while insured losses were significantly […]

Map showing significant economic loss events in 2022. Direct economic losses resulting from natural disasters in 2022 are estimated at $313 billion. This is close to the 21st century average, after adjusting actual incurred damage to today’s dollars using the U.S. Consumer Price Index. Though 2022 was far from record-breaking in terms of overall losses, it saw many impactful and costly events across the globe. Visualizing the geographic distribution of 2022 events allows for distinguishing certain patterns, including higher frequency of medium-sized Severe Convective Storm (SCS) events in the U.S. and Europe, and the prevalence of flooding events in Africa, Southeast Asia and Oceania. The map primarily shows the economic impact, which to some extent correlates with concentration of wealth — this is not a result of a reporting bias. What this map does not highlight is the humanitarian crises and displaced communities, as many events with significant human impacts do not necessarily translate into a high financial toll in terms of direct damage. Note that significant price inflation throughout the year already resulted in notable increases of per-event losses. Graphic: Aon

U.S. billion-dollar climate disaster events, 1980-2022. Storms, floods, wildfires and droughts caused a total of $165 billion in damages in the US last year, $10 billion more than the 2021 total and the third most costly year since records of major losses began in 1980, according to new US government data. With 18 disasters costing at least $1 billion in damages, 2022 was only marginally behind 2020 and 2021 in terms of the number of severe events. A total of 474 people died last year from these major calamities. Graphic: NCEI / NOAA

Extreme weather left 474 people dead and cost $165 billion in the U.S. in 2022 – “It does not seem likely that these trends will reverse. Perhaps we need to be more prepared for a future that has rapidly become our present.”

By Oliver Milman 10 January 2023 (The Guardian) – The US endured a particularly painful year as communities wrestled with the growing impacts of the climate crisis, with 18 major disasters wreaking havoc across the country as planet-heating emissions continued to climb. Storms, floods, wildfires and droughts caused a total of $165 billion in damages […]

The last 8 years were the hottest on record – “The rare event now would be to see a really cold year”

By Henry Fountain and Mira Rojanasakul 10 January 2023 (The New York Times) – The world remained firmly in warming’s grip last year, with extreme summer temperatures in Europe, China, and elsewhere contributing to 2022 being the fifth-hottest year on record, European climate researchers said on Tuesday. The eight warmest years on record have now […]
