Two-thirds of global heating caused by richest 10%, study suggests | Climate crisis | The Guardian

Výzkumníci z Mezinárodního institutu pro aplikovanou systémovou analýzu (IIASA) se v nové studii pokusili zmapovat, jak se příjmové nerovnosti a s nimi spojená vyšší či nižší spotřeba podílejí na klimatické změně.

Zjistili, že desetina nejbohatších lidí na světě je odpovědná za dvě třetiny globálního oteplení zaznamenaného od roku 1990.

Desetina nejbohatších přispěla sedmkrát více než průměr k celosvětovému nárůstu měsíčních extrémních teplot, jedno procento nejbohatších dokonce 26krát.

Zato 50 procent nejchudších obyvatel se na globálních emisích podílelo pouze z jedné desetiny.

Jak napsal server The Guardian, předchozí studie již dříve prokázaly, že skupiny s vyššími příjmy do atmosféry vypouštějí neúměrně velké množství skleníkových plynů. Nová studie se ale poprvé snaží určit, zda se tato příjmová nerovnost nějakým způsobem promítá do odpovědnosti za klimatickou krizi.

„Naše studie ukazuje, že extrémní klimatické dopady nejsou jen důsledkem abstraktních globálních emisí, ale můžeme je přímo spojit s naším životním stylem a investičními rozhodnutími, která zase souvisejí s bohatstvím,“ uvedla pro The Guardian Sarah Schöngartová, analytička klimatického modelování a hlavní autorka studie.

World faces new danger of ‘economic denial’ in climate fight, Cop30 head says | Cop30 | The Guardian
https://www.theguardian.com/environment/2025/may/28/andre-correa-do-lago-cop30-interview-climate-crisis

The world is facing a new form of climate denial – not the dismissal of climate science, but a concerted attack on the idea that the economy can be reorganised to fight the crisis, the president of global climate talks has warned.

André Corrêa do Lago, the veteran Brazilian diplomat who will direct this year’s UN summit, Cop30, believes his biggest job will be to counter the attempt from some vested interests to prevent climate policies aimed at shifting the global economy to a low-carbon footing.

“There is a new kind of opposition to climate action. We are facing a discredit of climate policies. I don’t think we are facing climate denial,” he said, referring to the increasingly desperate attempts to pretend there is no consensus on climate science that have plagued climate action for the past 30 years. “It’s not a scientific denial, it’s an economic denial.”

This economic denial could be just as dangerous and cause as much delay as repeated attempts to deny climate science in previous years, he warned in an exclusive interview with the Guardian.

Global Temperatures

April 2025 was the second-warmest April globally, with an average ERA5 surface air temperature of 14.96°C, 0.60°C above the 1991-2020 average for April.
April 2025 was 0.07°C cooler than the record April of 2024, and 0.07°C warmer than the third warmest of 2016.
April 2025 was 1.51°C above the estimated 1850-1900 average used to define the pre-industrial level and was the 21st month* in the last 22 months for which the global-average surface air temperature was more than 1.5°C above the pre-industrial level.
The 12-month period of May 2024 – April 2025 was 0.70°C above the 1991-2020 average, and 1.58°C above the pre-industrial level.

Large Cloud Feedback Confirms High Climate Sensitivity
https://mailchi.mp/caa/large-cloud-feedback-confirms-high-climate-sensitivity

Earth is getting darker, reflecting back to space a decreasing portion of the sunlight incident on Earth. This provides crucial information on cloud changes and climate sensitivity. See - 14 May Large Cloud Feedback Confirms High Climate Sensitivity -

“Earth’s albedo (reflectivity) declined over the 25 years of precise satellite data, with the decline so large that this change must be mainly reduced reflection of sunlight by clouds. Part of the cloud change is caused by reduction of human-made atmospheric aerosols, which act as condensation nuclei for cloud formation, but most of the cloud change is cloud feedback that occurs with global warming. The observed albedo change proves that clouds provide a large, amplifying, climate feedback. This large cloud feedback confirms high climate sensitivity, consistent with paleoclimate data and with the rate of global warming in the past century.”

Leon Simons (looking up)

“The Greenhouse Gas CO₂ equivalent concentration is now about 573 ppm.

Which would take 206% of preindustrial CO₂!

That's a stronger GHG forcing change than occured between the Last Glacial Maximum (LGM, when global sea levels were ~130 meters lower than today) and 1750!”

Vzhledem k tomu, že 10% je 800 000 nejbohatších, tedy v podstatě s velkou pravděpodobností i my všichni (třeba každý druhý na Západě?) se obávám, že to může být i pravda.

Over the past 12 months, cat bonds have returned approximately 13%, significantly outperforming both US Treasuries (up 5%) and the S&P 500 (down 5%), according to data from the Swiss Re Global Cat Bond Performance Index. Year-to-date, cat bonds are up around 1%, compared to a 15% drop in the S&P 500, underscoring their resilience as EU and Chinese retaliation against US tariffs intensifies pressure on global equity markets.

With over $50bn in outstanding issuance, the catastrophe bond market is attracting increased interest from hedge funds seeking non-correlated returns. Issuance hit a record high last year, driven by rising demand from insurers and reinsurers looking to transfer climate-related risks—such as hurricanes and wildfires—to capital markets.

“Cat bonds don’t trade with equity or credit markets,” noted Fermat. “They are a pure play on natural catastrophe risk, which is why they continue to act as a shock absorber in diversified portfolios.”

The Copernicus Climate Change Service (C3S) has published its latest climate bulletin for March 2025.

This data visualisation, based on C3S data, shows the total precipitation anomaly in Europe for the month.

It highlights that most of southwestern Europe was affected by above average levels of precipitation, particularly over the Iberian Peninsula.

This region was hit by a series of severe weather events which led to widespread flooding.

On the other hand, in the UK, Ireland, and a section of central Europe expanding southward to the Black Sea, Greece, and Türkiye, the month was drier than average.

C3S provides open data, which is essential for monitoring global climate trends. This information provides evidence-based insights for the creation and implementation of climate strategies.

Trump’s new 10% universal tariffs – which are higher for many major economies – are wreaking havoc on the global economy and are expected to increase consumer prices in the US. But the levies will not apply to many fossil fuel products, including liquefied natural gas imports, crude oil from Canada, and materials needed for making petrochemicals.

Dramatic cuts in China’s air pollution drove surge in global warming | New Scientist

A recent surge in the rate of global warming has been largely driven by China’s efforts to reduce air pollution, raising questions about how air quality regulations are influencing the climate and whether we fully understand the impact of removing aerosols from the atmosphere. This extra warming, which was being masked by the aerosols, accounts for 5 per cent of global temperature increase since 1850.
