Map of the UK showing weather stations where June temperature records were broken. The stations are marked by triangles; the taller the peak, the bigger the gap between the old record and the new one. More than 170 weather stations broke their previous temperature record, mainly across England and Wales. A few local records were also broken in Scotland and Northern Ireland. The biggest record-breaking margin was Lingwood in Norfolk, which broke its previous June record by 6 degrees Celsius.
New York Times Sankey diagram of oil and gas flow through the Strait of Hormuz, rotated horizontally
Satellite image shows 20km long oil spill next to Strait of Hormuz, and a zoom on the Iranian drone carrier that was hit by US strike on 6 March.
gallery of 9 satellite images from 3 January 2025 to 1 March 2026 showing A23a iceberg becoming smaller and smaller as smaller icebergs break away, and melt ponds appear on the surface.
Map of Antarctica's elevation beneath the ice. Blue areas indicate land below sea level, and brown areas indicate land above sea level. Large regions, especially in West Antarctica, lie below sea level. The new map reveals with more detail what landscape hides beneath the ice, with some corresponding photographs of similar landscapes in other parts of the world today, such as Alpine mountains, plateaus dissected by deep glacier-carved valleys, and flat plains.

Map of sea surface temperatures in the Mediterranean Sea showing parts of it reached 30C such as off the coast of Calabria, and the islands of Majorca and Sicily. Below the map is a chart showing daily maximum temperature at a buoy next to Majorca where it reached 30C for the first time this early in the season.

Map showing South Georgia island and the bathymetry around it, with overlaid the position of A23a iceberg, grounded on shallow seafloor south west of the island, about 80km away from it.
Two maps showing sea-ice concentration on 12 February 2025 for both Antarctica and the Arctic. For each map, the median extent for the 1981-2010 period is shown and areas of missing sea-ice are visible.
Two multiple line charts showing daily sea-ice extent for the Arctic on one side, and Antarctica on the other side. Each line is a year, with 2025 line breaking a record daily low for the Arctic for the time of year, and just shy of the 2023 record daily low for Antarctica.
Multiple line chart showing daily sea-ice extent for Antarctica and the Arctic combined. Each line is a year, with 2025 line breaking a record low on latest data of 13 February, breaking the previous record set in 2023.
Map of Northern Europe showing how temperatures would change after eventual AMOC collapse. Cities like London, Reykjavik or Bergen would chill drastically, by almost 15C for some.
Satellite image from 10 January 2025 shows long oil spill of at least 25 km in the Kerch Strait
Map of the iceberg journey from where it broke off from in Antarctica, to where it currently is. Points are coloured by year. It was stuck on seafloor for 30 years, but got on the move in 2022, and moved along the seafloor ridge to now less than 300km of South Georgia island.
Satellite image from DSCOVR EPIC showing the whole globe, with South America, Africa and Antarctica in view. Iceberg A23a is visible as a small white dot off the coast of Antarctica. A zoom in image from MDIS shows how close it is to South Georgia island.
Maps of air temperature anomaly foe each year since 1970 to 2024. Little maps are getting from blue to red with the last 10 years all very red as it is getting warmer than normal.
Ridgeline chart showing the distribution of global daily air temperature differences from the pre-industrial reference period (1850-1900), for every year between 1940 and 2024. Each individual year resembles a hill, shaded in a darker shade of red and further to the right for warmer years. The trend is clearly towards warmer years, with 2024 standing out as first year above 1.5C.
