Tag Alignment is the Name of the Game

Across the whole file, the source reads as a single continuous argument. It opens with: "The IPCC Sixth Assessment Report concludes that human influence has unequivocally warmed the atmosphere, ocean and land." Its centre of gravity: "Confidence in the long-term trend is very high because independent datasets, produced with different sampling and homogenisation methods, converge within a narrow envelope.". The through-line closes on: "Uncertainty in the preindustrial baseline itself (~0.1 °C) is the dominant contribution to uncertainty in stated anomalies for near-1.5 °C thresholds."

At the wide scope, grouped sections trace a broad thematic arc. It opens with: "Overview The IPCC Sixth Assessment Report concludes that human influence has unequivocally warmed the atmosphere, ocean and land." Its centre of gravity: "Confidence in the long-term trend is very high because independent datasets, produced with different sampling and homogenisation methods, converge within a narrow envelope.". The wide arc closes on: "Uncertainty in the preindustrial baseline itself (~0.1 °C) is the dominant contribution to uncertainty in stated anomalies for near-1.5 °C thresholds."

At the medium scope, one section speaks in its own voice. It opens with: "Overview The IPCC Sixth Assessment Report concludes that human influence has unequivocally warmed the atmosphere, ocean and land." Its centre of gravity: "Confidence in the long-term trend is very high because independent datasets, produced with different sampling and homogenisation methods, converge within a narrow envelope.". The section point closes on: "Uncertainty in the preindustrial baseline itself (~0.1 °C) is the dominant contribution to uncertainty in stated anomalies for near-1.5 °C thresholds."

At the narrow scope, a single passage crystallises the claim. It opens with: "Overview The IPCC Sixth Assessment Report concludes that human influence has unequivocally warmed the atmosphere, ocean and land." Its centre of gravity: "Global surface temperature in the decade 2011–2020 was 1.09 °C higher than 1850–1900, with a larger increase over land (1.59 °C) than over the ocean (0.88 °C).". The close reading closes on: "Global surface temperature in the decade 2011–2020 was 1.09 °C higher than 1850–1900, with a larger increase over land (1.59 °C) than over the ocean (0.88 °C)."
