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 […]

More than 90 percent of rainforest carbon offsets by biggest certifier are worthless, analysis shows – “It’s disappointing and scary”

By Patrick Greenfield 18 January 2023 (The Guardian) – The forest carbon offsets approved by the world’s leading certifier and used by Disney, Shell, Gucci and other big corporations are largely worthless and could make global heating worse, according to a new investigation. The research into Verra, the world’s leading carbon standard for the rapidly growing $2bn (£1.6bn) […]

Saving a Belize village from man-made erosion – “I don’t want to see more graves go to the sea”

8 January 2023 (UN News) – “My grandma and my grandfather are now washed out in the sea,” says Mario Muschamp, gazing out at the coast near his close-knit Creole community. “You know, their graves are gone. That really hurts.” This is the reality for the inhabitants of Monkey River, who have watched on, powerless, […]

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

Network map showing followers for key amplifiers of climate disinformation during COP27, grouped by common traits or identifying factors. Network mapping around COP26 showed that, among accounts following key climate misinformers on Twitter, 7.5 percent were primarily focused on climate - for COP27 the cluster constitutes a mere 0.33 percent. The shift reveals how right-wing ‘culture war’ influencers are becoming the most prominent voices in spreading climate misinformation. Such content drives an ecosystem in which environmental issues, including COP summits, can more easily be framed and amplified as a polarising topic - a trend covered in depth by a recent peer-reviewed paper in Nature Climate Change. Overall, the audience for key misinformation influencers has a similar composition to last year’s COP26 network. Accounts in the ‘U.S. Conservative’ cluster comprise the largest portion of the map, including highly influential pundits like Dinesh D’Souza (2.9m followers) and Tom Fitton (1.9m followers) alongside elected officials like House Rep. Lauren Boebert (2m followers) who focus on broadly right-wing “culture war” issues. Taken together, the US, UK, and Canada Conservative clusters make up 72.25 percent of the overall network. While climate issues do not dominate their content strategy, these accounts do share related misinformation during key climate-related events, including COP, or as part of wider outputs. Climate content regularly features alongside other misleading, disproven and/or unsubstantiated claims on an array of topics, including around electoral fraud, vaccinations, the COVID-19 pandemic, migration, and child trafficking rings run by so-called ‘elites’ Graphic: Climate Action Against Disinformation / Graphika

John Hornewer picked up a quarter […]

Estimated ocean parasite populations in the Puget Sound, 1880-2019. The count per host of ocean parasites that obligately require three or more hosts declined through time, while that of two- and one-host parasites remained stable. Shown are model predictions between the years 1880 and 2019 from phase 1 analysis. Predictions are for the “average” parasite species within each group (i.e., within 1-host parasites, 2-host parasites, and 3+-host parasites) where average is defined as “the parasite species with the abundance that is closest to the average abundance of all parasite species.” Graphic: Wood, et al., 2023 / PNAS

Warming oceans have decimated marine parasites, and that’s not a good thing – “If this can happen unnoticed in an ecosystem as well studied as this one, where else might it be happening?”

By Hannah Hickey 9 January 2023 (UW News) – More than a century of preserved fish specimens offer a rare glimpse into long-term trends in parasite populations. New research from the University of Washington shows that fish parasites plummeted from 1880 to 2019, a 140-year stretch when Puget Sound — their habitat and the second […]

Cognitive differences between groups of people who were directly exposed to the Camp Fire in 2018, people who were indirectly exposed (who witnessed the fire but were not directly impacted), and age- and gender-matched non-exposed controls. Event-related potential responses (ERPs) elicited on the interference processing task and their relationship to behavior. (A) Group averaged ERPs ± standard error are shown at frontal (F3, F4) and parietal (P3, P4) channels corresponding to the directly exposed (red), indirectly exposed (blue) and unexposed control (green) groups. Red and orange bars depict significant peak amplitude differences between the directly exposed vs. control group, and the directly exposed vs. indirectly exposed group (p

Greta Thunberg: It’s “absurd” to think oil companies causing the climate crisis have a solution to it – “As long as they can get away with it, they will continue to invest in fossil fuels, they will continue to throw people under the bus”

By Rachel Koning Beals 19 January 2023 (MarketWatch) – Swedish climate campaigner Greta Thunberg, age 20 and arguably the face of a generation that wants to roll back decades of reliance on oil and gas by means of alternative energy sources, had a message Thursday as she mingled with the corporate and political bigwigs meeting […]
