4 Billion Years On

Country & Region Updates

Monthly climate updates for 248 places - every continent, plus countries, US climate regions, US states and UK regions. Temperature, rainfall and emissions trends from NOAA, Copernicus ERA5, GPCC and the Met Office. In Sep 2026, 97% of the 169 countries tracked were warmer than their 1961–1990 baseline.

FAQs

FAQs

What is on the Country & Region Updates page?

A monthly climate update for every continent, country, US climate region, US state and UK region we track, plus the global record. Each place has its own page with its temperature, rainfall, shifting seasons, records and climate history, set against established baselines, and for countries their emissions and electricity mix.

How do I move between places?

Search, browse a section or click the map on this page to open a place. On every place page, the trail under the title (for example Country & Region Updates › Europe › France) leads back up, and Change place opens the same search, list and map to jump straight to another. Coming back here returns you to the section, search and scroll position you left.

Which regions are covered?

Every country with full climate records, every US state, every UK home nation (England, Scotland, Wales, Northern Ireland) and every English region (South East, North West, Midlands, London and the rest). Continental groups (Europe, Africa, Asia, North America, South America, Oceania) and the US climate regions are also covered.

Where does the data come from?

Country and continent temperatures: Copernicus ERA5 (C3S), with Our World in Data as a fallback. Rainfall: GPCC (DWD), with World Bank CCKP / CRU TS filling gaps. Global temperature, US states and US climate regions: NOAA NCEI. UK nations and regions: the Met Office UK Regional Series. Emissions: Global Carbon Project via Our World in Data.

How often is it updated?

Most underlying datasets refresh on a monthly cadence, and the climate hub refreshes at the same cadence - typically within days of the previous month's figures being released. Live indicators (CO₂, methane, sea ice, ENSO state) update more frequently from their source APIs.

Where can I see the rankings or methodology?

The full league table is on the Climate Rankings (sortable 1-month, 3-month and 12-month anomaly for every region we track). The Methodology & Sources details every data source, baseline and refresh cadence used on the site.
