Diagramme météo suisse indiquant les anomalie de T° et de précipitations des quadrimestres avril-juillet depuis 1901 (observations) par rapport à la normale 1991-2020. Les cercles vides montrent des valeurs simulées dans le cadre d'un réchauffement climatique global de 1,5 °C.  Le réchauffement a atteint (en 2025) 1,4 °C à l'échelle globale et environ 3,0 °C en Suisse, en comparaison avec la moyenne préindustrielle 1871-1900.  Dans ces conditions climatiques, l'année 2026 serait également considérée comme particulièrement sèche et chaude. Néanmoins, les données montrent aussi que des étés encore plus chauds et secs seraient déjà possibles aujourd’hui.

Carbon capture and storage is the subject of considerable hype – but as it stands, very little CO2 is being captured and stored.
Annual global CO2 emissions from fossil fuels, compared to amount captured and stored. A square chart visually compares total fossil CO2 at 38.1bn to a tiny 0.06bn captured and stored. CCS projects currently capture less than 0.2% of the world's fossil-fuel emissions. Source: IEA, Global Carbon Budget.

European summer temperature, June to August, over 10°W-40°E, 30-50°N, the region Stott et al. used for the 2003 heatwave, relative to 1961-1990. The black line shows ERA5 observations from 1950 to 2025, rising from about zero in the mid-twentieth century to 2.75°C in 2024. Grey shading is the 5-95% range of 34 CMIP6 models over the historical period, blue shading the same models under SSP2-4.5 to 2100, with the running median in white. Two dotted lines mark the 2003 summer at 2.06°C and the 2024 summer at 2.75°C, each dropping to the year the model median reaches that level: 2027 and 2045. Model region approximated by the IPCC AR6 Mediterranean and West & Central Europe regions, weighted 0.75 to 0.25.
