Climate Change - Evidence, Attribution, Projections and Remedies
Climate change from the 1970s to June 2026: the measured surface-temperature record (HadCRUT5, NASA GISTEMP, NOAA, Berkeley Earth) and cryosphere proxies (NSIDC sea-ice, snow cover, glacier mass balance, ocean heat content), biodiversity feedbacks, attribution to fossil-fuel carbon, and forward projections under current-trend and modelled scenarios (IPCC AR6, CMIP6 SSPs), through to the evidence base for remedies from ocean and land carbon sinks to solar geoengineering, weighting recent authoritative sources (IPCC, PNAS, Nature Climate Change, Copernicus/ECMWF) over older ones.

Full brief
Read the synthesised summary→
The climate story split into two registers over the past eighteen months. The physical science kept producing records, and the financial system started pricing them. In 2024 the planet crossed 1.5°C above pre-industrial for a full calendar year for the first time, confirmed by five independent science agencies, and…

The surface temperature record from five independent datasets, HadCRUT5, NASA GISTEMP, NOAA GlobalTemp, Berkeley Earth, and ECMWF ERA5, converges on 2024 as the warmest year in the 175-year instrumental record, at approximately 1.55 to 1.62 degrees C above…

The most prominent Substack voice on the instrumental record is James Hansen's Climate Uncensored, where Hansen, Kharecha, Morgan and Vest published December 2025 analysis projecting the 2023–2025 mean at +1.5°C relative to 1880–1920, and arguing that an…

Financial Press
The financial press framing of climate change through 2025 and into 2026 has shifted decisively from long-run scenario planning towards the measurement of present-day economic damage. Bloomberg's January 2025 feature confirmed that 2024 was the first calendar…

VC & Analyst Reports
The most consistent signal from VC and analyst coverage in 2024 and 2025 is a two-speed market: overall climate tech venture funding contracted sharply while a small set of sectors, chiefly grid technology, nuclear, and direct air capture, attracted…
