Köppen-Geiger climate maps of Europe reveal zones migrating hundreds of kilometers north from 1930 to 2099. Mediterranean climate expands into France and interior Iberia, subarctic retreats in Scandinavia, continental shifts northeast, and Alpine tundra vanishes from lower peaks under ssp2-4.5 scenario.

Köppen-Geiger climate maps of New Zealand reveal mountain climate zones disappearing from 1930 to 2099. Cool-summer oceanic climate (Cfc) vanishes from North Island, tundra patches (ET) disappear from Southern Alps peaks, subarctic zones (Dfc) shrink dramatically, and cold steppe (BSk) contracts under ssp2-4.5 scenario.

Köppen-Geiger climate maps of Australia reveal desert expansion from 1930 to 2099. Hot desert (BWh) and steppe (Bsh) zones spread hundreds of kilometers toward Sydney, Brisbane, Melbourne, and Perth. Habitable climate zones supporting population centers get compressed coastward under ssp2-4.5 scenario.

Köppen-Geiger climate maps of the British Isles reveal mountain climate zones disappearing from 1930 to 2099. Tundra patches in the Grampians vanish by the 2070s, extreme cold zones disappear by the 2090s, and the Pennines lose their cool-summer classification entirely under the ssp2-4.5 scenario.

Köppen-Geiger climate maps of Canada reveal dramatic northward shifts from 1901-1930 to 2077-2099. Animated comparisons show tundra retreating to Arctic islands, subarctic zones moving hundreds of kilometers north, tree line advancing, and southern continental climates warming under the ssp2-4.5 scenario.

New Köppen-Geiger climate maps of the United States reveal dramatic shifts from 1901-1930 to 2077-2099. Watch animated comparisons showing how tundra retreats in Alaska, continental zones move north, and arid regions expand in the West under the ssp2-4.5 climate scenario.

People often prefer Mediterranean climates for their gentle seasons and reliable weather. From the Mediterranean Basin to California, central Chile, South Africa’s fynbos and Australia’s mallee, the same seasonal pattern gives rise to distinctive shrublands and woodlands.

Earth’s seas are rising today, but the long-term future holds both floods and droughts on a planetary scale. See maps I created showing what our world would look like if all ice melted, if alien oceans were added, and when Earth eventually runs dry.

Remember when October actually felt cool? Those days are fading. New climate data reveals every US county now has warmer falls than in 1970. The Southwest saw the biggest jumps – Reno warmed by 7.7°F (4.3°C). Explore interactive maps to see exactly how much your area changed.

If all the ice covering Antarctica, Greenland, (Antarctica would make about 60 meters of sea-level rise, Greenland about 60 meters) and in mountain ice caps around the globe were to melt, sea level would rise about 70 meters (230 feet) and cover all seaside cities.

Over the past 30 years, the Arctic has warmed at roughly twice the rate as the entire globe, a phenomenon known as Arctic amplification. Most scientists agree that this rapid warming is a signal of human-caused climate change.

Many of the world’s cities will face sharply different climates by 2050. I tried to visualize how climate change will affect 6,000 world cities. London could feel as hot as Paris by 2050, with Paris’s climate more like San Francisco. San Francisco feels like Melbourne and New York City like Bologna (Italy). The climate of Moscow will be similar to that of Boston.

The hottest years on record globally have occurred in recent times, with years like 2016, 2019, and 2020 being among the warmest due to the ongoing trend of global warming.
