In Bulgaria, 37% say earning money is the most important role of a man. In Poland, just 22% think it’s acceptable for men to cry. I mapped all of it from Special Eurobarometer 545.

Take that first question. Sweden: 95%. Poland: 22%. The EU average is 51%, meaning the continent is genuinely split on this. And nearly every other question in the survey produces the same geographic shape.

In the Netherlands, 3% see earning money as a man’s primary role and 2% see homemaking as a woman’s primary role. Bulgaria comes in at 37% and 35%. On whether men are naturally less competent at household tasks, Denmark records 3% and Bulgaria 28%.

On financial independence being equally important for both sexes, Poland lands at 40% and Sweden at 90%.

The communist period explains more of this than might initially seem obvious. Communist governments across Eastern Europe pushed women into the workforce at high rates. Female labor participation across much of the Eastern Bloc was genuinely substantial by the 1970s. But they left the household entirely alone. From the mid-1950s onward, state-ordained women’s organizations promoted a vision in which working women had to juggle their commitment to the workplace with their obligations toward the family, managing what became known as the “double burden.” The system encouraged women to hold full-time jobs while leaving domestic authority exactly where it had always been. The fall of those regimes and the economic difficulties of the 1990s did not lead to restructuring in most households.

Sweden and Denmark spent those same decades differently. Parental leave that fathers were expected to take, subsidized childcare, labor markets built around the assumption that women would work throughout their adult lives. Daily life organized that way, over enough decades, shifts what feels normal at home.

The countries on the conservative end of these maps (Bulgaria, Romania, Poland, Slovakia) also share strong Orthodox or Catholic traditions. Norris and Inglehart documented a consistent link between religious conservatism and stronger gender role distinctions in Sacred and Secular (Amazon link). Those same countries also largely overlap with the former Eastern Bloc, so working out which factor carries more weight is genuinely difficult.

One question breaks from the geographic pattern. On whether feminism has gone too far, Cyprus leads at 35%, Slovenia follows at 29%, then Spain at 27%. Spain, which records some of the lowest scores in this survey on breadwinner expectations and household decision-making.

Spain is a different case. The country pushed through an unusually large amount of gender legislation in a short period, a sexual consent law in 2022, mandatory gender quotas for party lists in 2023, and various other reforms in between. Laura Nuño Gómez, a political scientist at King Juan Carlos University in Madrid, noted that in Spain “as progress has been faster, the opposition to gender equality policies has also been more intense and animated.” Vox, whose campaign was built substantially around opposing feminist policy, took 12.4% of the national vote in 2023. That political context is probably where the 27% comes from, not from the same conservatism you’d find in Bulgaria or Slovakia. Portugal, worth noting, scores conservatively on financial independence (46%) but records just 5% on this question, the lowest in the EU.

Population has never moved in a straight line. Pandemics hollowed out cities in weeks. Colonization nearly erased entire continents. The Industrial Revolution compressed what should have been centuries of growth into a few decades.

10,000 BCE

The 10,000 BCE map created puts 26% of all humanity in North America and another 24% in South America. Half the world in the Americas!

The total global population was 4.5 million. Europe, for all its land area, held only 481,000 people. Africa, despite being where our species spent its first hundred thousand years, had just 228,000. There were no cities anywhere. Most people were hunter-gatherers, spread in small bands across six inhabited continents — and the two largest concentrations were in the Americas.

The Plague of Justinian (541–549 CE)

500 CE. The world holds 253.4 million people, and 70% of them live in Asia — 176.6 million, accumulated over thousands of years in the river valleys running from the Indian subcontinent east to China. In 541, that changed.

Emperor Justinian himself caught the plague and survived, which is how it got its name. Byzantine chroniclers recorded between 5,000 and 10,000 deaths per day in Constantinople at the outbreak’s height, with mass graves filling faster than gravediggers could keep pace. Historians still argue about the exact figures. What nobody disputes is that nothing in any earlier written record comes anywhere close.

The pathogen killed most efficiently where merchants and travellers crossed paths — ports, market towns, the roads connecting them. Rural Asia sat largely outside those networks and was mostly spared. Europe’s count fell from 28.6 million to 24.6 million by 600 CE. Alexandria and Antioch had been Mediterranean commercial anchors for centuries before 541; both shrank after it and never returned to their earlier scale. Asia grew from 176.6 million to 195.1 million.

A century after the outbreak, 18 million more people were alive globally than in 500 CE. The regions the plague couldn’t reach had kept adding up. The Byzantine Empire was a different matter — it never recovered the territorial control it had held before 541.

The Black Death (1347–1351)

In 1347, Yersinia pestis was back. The death toll over the following four years was on a scale the Justinianic outbreak never reached. Between a third and more than half of Europe’s entire population died. Some regions lost close to three-quarters of their people in under four years.

In 1300, the world held 456.2 million people. Asia stood at 279.8 million (59%). Europe had grown to 83.3 million, 18% of the global total, built on centuries of agricultural expansion and slow urban growth. The Americas, still entirely cut off from Old World pathogens, held around 50 million people combined.

By 1400, the world total had fallen to 442.3 million and Asia’s count had dropped from 279.8 to 270.8 million. Parts of England, France, and Italy lost between a third and half their people in a matter of years. Whole villages were abandoned. The labour shortages that followed broke open power relationships across Europe that had held for generations.

A net global decline of 3%. Unremarkable in percentage terms, historically significant as the first recorded instance of world population going backward, produced by a single pathogen moving along trade routes. The effects on European society outlasted the pandemic by centuries. The Church’s authority over ordinary life weakened sharply in the aftermath. Landowners who had never negotiated wages found themselves with no leverage. The intellectual response to the Black Death fed directly into the medical and philosophical shifts of the Renaissance. Population event and civilizational turning point — the two are genuinely hard to separate here.

The Americas, 1492–1600

Tenochtitlan, the Aztec capital, held between 200,000 and 300,000 people in 1500. No European city was that size. The Inca road network covered more than 40,000 kilometres. North America held 30.5 million people and South America 29.9 million. By 1600, North America was down to 3.8 million.

South America to 6.4 million. About 50 million people were gone in one century.

The primary mechanism was not conquest, though warfare was real. It was disease. Smallpox spread through populations with no prior immunity, often traveling indigenous trade networks before any colonizer arrived in person. Some communities were already devastated before they ever encountered a European.

Over that same century, the world’s total population edged up from 503 million to 516 million. Europe, Asia, and Africa more than covered the loss.

In 1500, the Americas held nearly one tenth of all humanity. In 1600, they held less than 1% of a larger world.

The Industrial Revolution (Late 1700s–1800)

In 1700, there were 595.5 million people on Earth. In 1800, there were 983.1 million. A 65% increase in one century — which doesn’t fully register until you consider that it had taken from the first Homo sapiens until approximately 1700 CE to reach 595 million. The following hundred years added 388 million more.

Improved agriculture, better food supply, and early gains in sanitation all played a role, though the gains were very unevenly distributed. Europe grew from 115.4 million to 192.9 million (67%). Asia from 386.9 million to 683.2 million (77%). North America grew from 6.8 million to 14.8 million, almost entirely through European immigration. Indigenous populations remained severely diminished and contributed little to that number. Africa added only about 2.7 million people across the whole century, going from 78.6 million to 81.3 million, even while the transatlantic slave trade was forcibly removing tens of millions from the continent.

The 1800 cartogram is the first in this series that looks anything like the world we know. Asia dominates, Europe is substantial, the Americas are beginning to refill. The billion mark arrived a few decades later. Each subsequent billion came faster than the one before it, and the intervals have kept compressing.

The Map Today

Asia has 4.8 billion people today, 59% of humanity. Africa 1.5 billion (18%), Europe 747 million (9%), North America 608.8 million (8%), South America 433 million (5%), Oceania 45.6 million (1%).

North America’s trajectory across these maps is the most dramatic of all. In 1600, the continent held fewer than 4 million people. It now holds 608 million, rebuilt through immigration. Indigenous populations never came close to recovering their pre-1492 numbers. Most of Africa’s growth happened after 1950. Asia’s share has been declining gradually as birth rates fall — particularly in East and South Asia.

Continental Peak Shares: Who Held the Highest Proportion of Humanity, and When

Asia’s all-time peak of 71.8% came in 600 CE, directly after the Plague of Justinian had gutted the Mediterranean world while leaving much of rural Asia intact. Europe peaked in 1908, after industrialization and colonial-era demographics had placed roughly a quarter of all humanity within European-origin populations. That share has declined in every decade since.

Africa at 18.3% in 2023 has never been higher in the dataset. It is the only major region where the peak is almost certainly still ahead.

The Population Peak

The UN currently puts the likely global peak somewhere around 10.3 billion, expected to arrive in the mid-2080s. In a growing number of countries, birth rates have already fallen below replacement level. At some point after the peak, the global total may start drifting downward as populations in parts of Europe and East Asia begin to shrink outright.

Africa is the only major region growing fast enough to shift the cartogram substantially in the coming decades. Asia’s share is already edging down. Europe’s absolute population is projected to shrink within decades. The 2100 map will almost certainly show an Africa larger than at any point in the 12,000 years covered here.

The post From 4.5 Million to 8 Billion: How Earth’s Population Changed Over 12,000 Years appeared first on Vivid Maps.

Before the 20th century, roughly a quarter of children in most parts of the world didn’t reach their fifth birthday. In some regions and periods it was closer to half.

Industrialization pushed childhood mortality down. Then 20th-century public health accelerated it — mass vaccination, cleaner water supplies, antibiotics. But families didn’t immediately start having fewer children just because fewer were dying. It took a generation, sometimes two, before birth rates adjusted. During that lag, population grew faster than at any point in recorded history.

Green countries are above 2.1 children per woman — the rate at which a population can hold steady without immigration. Red is below it. Africa and much of Central Asia are green. Most of the rest of the world is not.

The whole of Sub-Saharan Africa sits well above 2.1. Chad is at 5.94, Somalia 5.91, DR Congo 5.90. The region is still in that lag period: child mortality has improved significantly over recent decades, but the economic and social conditions that eventually pull birth rates down — access to education for girls, urbanization,
contraception — are running on a different timeline than they did in, say, South Korea or Iran a generation ago.

Europe and East Asia have been below replacement for a long time. Japan has been below 2.1 for close to forty years. Governments across Southern and Eastern Europe have handed out cash payments for new babies, built more daycare centers, extended parental leave — Italy is at 1.20 now, Spain 1.21. South Korea
has spent more on incentivizing births per capita than almost any country on Earth and is down to 0.75, the lowest rate of any sovereign nation in this dataset.

Iran is at 1.67. Brazil 1.60, Argentina 1.51. Mexico is at 1.87. These are countries that spent decades being associated with rapid population growth. India crossed below 2.1 around 2020 and is at 1.94 now. The Philippines was at 6.0 in the early 1960s and is at 1.88 today. The perception of these places as high-fertility countries has simply not kept pace with the data.

The world average is 2.24. Above 2.1, yes, but not by much, and without Sub-Saharan Africa it would already be below replacement.

Interestingly, Israel is at 2.75 — high for a country at its income level, the product of religious demographics anddecades of active government support for larger families. Kazakhstan is at 2.95, Uzbekistan 3.45, Tajikistan 2.99. Most of these countries are still heavily rural, and in practice it’s urbanization that pulls birth rates down more consistently than any policy. Bangladesh is at 2.11, essentially sitting on the line. Lebanon is at 2.21 and has been falling for years.

For most of the 20th century, the population concern dominating political thinking was overpopulation — too many people pressing against limited food and resources. In parts of the world where birth rates are still high, that concern is still real. But in most of Europe, East Asia, and now growing parts of Latin America, the actual problem governments are dealing with is the opposite: workforces shrinking faster than pension systems can absorb, and smaller cities losing residents with nothing reversing it. China ended the one-child policy in 2015 and has been running incentives to have more children ever since, with almost nothing to show for it. No country has worked out how to meaningfully raise a fertility rate once it has dropped this far.

By 2035, a lot more of this map will be red.

Russia and Kazakhstan are treated as Asian countries here, since most of their territory is in Asia.

Europe comes out at 4.08 countries per million km². South America is at 0.67, roughly six times less. South American territories came out of independence roughly the size they went in and never really fragmented. In Europe, small principalities and kingdoms spent centuries competing and surviving, and a few of them are still sitting in the table below as fully sovereign nations today.

Population data by continent follows.

North America (23 countries)

Three countries hold almost all the weight here. Past Canada, the table shifts into a different category entirely — mostly small Caribbean island nations, some with populations a large university would match.

South America (12 countries)

Brazil alone covers roughly half the continent in both territory and population. Guyana and Suriname are each larger than the United Kingdom yet together have only about 1.4 million people. The Caribbean subregion of North America ended up with more sovereign states than all of South America.

Europe (43 countries)

Monaco covers 2 km². Vatican City has 882 residents and Rome surrounds it on all sides. San Marino and Liechtenstein are under 200 km² each. All four are fully recognized sovereign nations. Ukraine is Europe’s largest country by area, Russia aside, and France ranks second.

Africa (54 countries)

[INSERT AFRICA TABLE HERE]

Algeria is bigger than all of Western Europe. São Tomé and Príncipe covers about 1,000 km². Nigeria, which takes up a relatively small fraction of the continent visually, has 230 million people in it.

Asia (49 countries)

Bangladesh has 173 million people packed into an area smaller than Greece. Mongolia’s territory is four times Germany’s size, with 3.5 million people in it. India and China together approach 3 billion, more than all the other 47 countries in this region combined.

Oceania (14 countries)

Australia and Papua New Guinea together account for the vast majority of the region’s population. The remaining 12 countries are all island nations, most with populations under a million.

The post How Many Countries Does Each Continent Have? appeared first on Vivid Maps.

Massachusetts topped the list in 2000. Homes there averaged $192,616. Hawaii was next at $191,347. California came in at $185,997. Scan through the data for all fifty states and you’ll notice something. None of them broke $200,000.

Twenty-five years pass and that’s completely changed. Just Mississippi and West Virginia have averages below $200,000 now. Everyone else crossed it.

Looking at raw numbers doesn’t tell you much by itself. A dollar bought more in 2000 than it does now. I adjusted all the old prices for inflation so we’re comparing actual purchasing power, not just watching digits get bigger.

Look at Hawaii. Homes there averaged $191,347 in 2000. Fast forward to today and you’d expect them to cost around $367,386 just from inflation doing its normal thing. But they’re actually at $816,383. That’s 122% higher than inflation alone would explain. Homeowners gained almost $449,000 in real purchasing power per home.

California’s similar. Those $185,997 homes should be around $357,115 if they’d only matched inflation. They’re at $755,330 instead. Real gain of $398,216 per home, which is 111.5% above inflation.

The expensive northeastern states got even more expensive. Massachusetts hit $636,412, which is 72% beyond inflation. New York’s at $498,383 (up 72.76% in real terms). New Jersey reached $556,462, gaining 72.57%.

Idaho caught me off guard. It’s always been the affordable western state. Prices there jumped 97.3% above inflation. A $122,253 house in 2000 costs $463,123 now. Maine climbed 97%. New Hampshire went up 95.67%. These places don’t have the same geographic constraints as coastal markets, but they still saw massive appreciation.

The Mountain West shows a different pattern. Colorado’s combination of mountain communities and the Denver metro pushed state averages to $529,754, up 58.27% in real terms. Utah gained 64.63% above inflation. Montana and Wyoming don’t have 2000 data available, but their 2026 averages sit well above $350,000.

The Midwest barely moved. Illinois went up 15.08% in real terms. Michigan gained 15.02%. Ohio rose 18.92%. Over a 25-year span, those are tiny increases. Maybe these states built enough housing to keep up with demand. Or maybe their economies struggled in ways that kept prices flat. Probably some combination of both.

Louisiana is the only state where prices actually fell compared to inflation. It dropped 0.57%. Those $108,003 homes from 2000 would be worth $207,366 if they’d tracked with inflation. They’re at $206,193 instead. Katrina hit in 2005 and the housing market there just never bounced back. Twenty years later and you can still see it in the data.

The South had moderate but steady gains. Florida went up 80.43% above inflation even with hurricane season every year. Texas rose 37.29%. Tennessee climbed 52.1%. All beat inflation but didn’t match what happened on the coasts.

Why did different regions end up so far apart? Geography plays a big role. You can’t build more beachfront no matter how much demand there is. Tech companies concentrated in certain metros and started paying people ridiculous salaries. Remote work changed everything in the 2020s. People could suddenly live anywhere and keep their high-paying jobs. Some moved to Idaho, others to Maine. Meanwhile certain cities had zoning rules that basically prevented new construction. Each state got its own mix of these pressures.

Someone who bought a Massachusetts home in 2000 gained $266,589 in real purchasing power without lifting a finger. Just owned the property. Someone in Mississippi gained $16,118. Someone in Louisiana lost money in real terms. Housing worked as a geographic lottery for building wealth.

Affordability in 2000 looked completely different. Mississippi averaged $88,614 for a home. West Virginia sat at $72,434. Families with median incomes could actually buy houses in these places. Today even the cheapest states have crossed $165,000, and that’s just the average.

Only two states still have averages under $200,000. Mississippi’s at $186,256. West Virginia’s at $168,655. Every other state needs six figures to hit the average price. A $200,000 house from 2000 should run about $384,000 now if it just kept pace with inflation. Most markets went way past that.

The Carolinas are worth mentioning because they managed to grow without going crazy. North Carolina went up 33.83% above inflation. Homes there average $327,663 now. South Carolina’s at $296,981 after a 36.76% real increase. Both attracted new residents but avoided the price explosions you see in other growing states.

The American housing market got completely reorganized over these 25 years. Broad affordability turned into regional stratification. States that already cost more in 2000 mostly pulled further ahead. Some cheap markets suddenly weren’t cheap anymore, pushing out people who’d lived there for generations.

Africa has 754 million Christians. Europe has 552 million, and North America has 401 million. If you add up the numbers, Africa has more Christians than Europe and North America combined.

In 1900, Africa had maybe 10 million Christians. Now, just 120 years later, the number has grown about 75 times!

South America comes in second globally with 400 million. Brazil alone has 185 million Catholics. That’s more Catholics than any other country in the world.

Asia has 417 million despite being home to more than half the world’s population. The Philippines holds 93 million of Asia’s Christians, basically a quarter of the continent’s total. Three centuries of Spanish rule left their mark.

Russia is home to 105 million of Europe’s Christians. Without Russia, the number of Christians in Europe would be much lower. In many Western European countries, especially among people under 40, church attendance has become less common.

The religion started with a handful of people in Jerusalem. Now there are churches on Arctic ice and underground house churches in places where it’s illegal to practice.

Technology opened things up first with submarines and icebreakers and satellites. At the same time the climate warmed and the calendar of ice shortened. Satellites have watched summer ice shrink since 1979, losing on average about 12 percent every decade. Routes that used to be blocked for months at a time are now open longer. Russia already moves cargo along the Northern Sea Route for much of the year. Some climate models still point to summers with almost no ice by 2030.

Why the scramble? Treasure and transit. According to the U.S. Geological Survey, the Arctic seabed holds tens of billions of barrels of oil and over a thousand trillion cubic feet of gas. Greenland is also believed to have about 1.5 million tonnes of rare earths, which are important for batteries and electronics. Shipping through the Arctic can cut almost three weeks off the journey from Asia to Europe compared to using the Suez Canal. When time is money, those savings add up fast.

Six countries have drawn territorial claims.

Russia reopened over 50 military bases since 2014. Thirteen airfields, 10 radar stations. They’ve got eight nuclear icebreakers running. Everyone else combined? Three, maybe. Year-round Arctic access while others can’t.

Canada says the Northwest Passage is theirs. The U.S. calls it international waters. Both run military drills there now.

Greenland matters because China makes 60% of the world’s rare earths. Denmark filed their Arctic claim in December 2014. It overlaps with Russia’s claim.

The map shows 90°N falls outside everyone’s 200-mile zones. International law says that’s open ocean. Countries keep filing claims anyway, saying underwater ridges connect to their land.

Russia filed for the Lomonosov Ridge in February 2023. It’s an 1,800-kilometer (1,118-mile) underwater mountain range. They say it extends from Siberia. Canada filed in December 2022 saying it’s connected to North America. Denmark sided with Canada. The U.N. checks the geology but won’t pick sides. Countries have to negotiate directly. That takes decades.

Ice keeps melting. The 1980s had 7 million square kilometers (2.7 million sq mi) of summer ice. Now? Under 4 million square kilometers (1.54 million sq mi). Greenland dumps 280 billion tons yearly.

Norway approved Arctic drilling for 2025. Sweden’s LKAB found 1+ million tons of rare earth oxides near Kiruna in 2023. Norway found bigger deposits at Fen Carbonatite. China built polar icebreakers and calls itself “near-Arctic” despite being nowhere close.

Russia’s icebreakers run all year. Their bases cover the whole Arctic coast. The U.S. talks expansion but hasn’t built the ships. Finland and Sweden joining NATO added northern territory, but Russia already had their infrastructure up.

Who controls the Arctic? Whoever can operate ships and bases up there. Russia’s got that now. Trump wants Greenland’s rare earths and location. China’s building icebreakers anyway. Trillions in resources guarantee this keeps going.

The post Who Controls the North Pole? appeared first on Vivid Maps.

What creates such extremes? The Himalayas run for thousands of kilometers, acting as this massive wall basically. Air coming from the south hits it and releases all its rain on India’s side, leaving Tibet really dry. Distance from the sea is key too – coastal spots stay milder with ocean moisture, while inland areas get extreme temps. Monsoons change course every season, dumping tons of rain in summer and leaving vast areas dry come winter. And yeah, Asia spans from nearly the Arctic Circle right down to the equator.

But these setups are changing now. I tracked how Asian climate zones have moved since 1930 and where they’re going by 2099 using data from Beck et al. (2023) at 1-kilometer resolution. The changes vary by region but add up to major reorganization. For climate codes and what they mean, check my earlier post on global classifications.

Today’s map shows Asia’s extremes. Up along the northern coast of Siberia, you’ve got Arctic tundra (ET), and the islands have polar ice (EF). Then there are these huge stretches in Siberia and northern Russia that are subarctic (stuff like Dfc, Dfd, Dwc, Dwd). Hot deserts (BWh) and cold deserts (BWk) fill Arabia, and chunks of central Asia. Tibet and Mongolia have cold desert and steppe (BWk, BSk). Southeast Asia and southern India hold tropical rainforest (Af). Those rainforests are bordered by savanna (Aw) and monsoon (Am) zones. Over in eastern China and bits of India, it’s humid subtropical (Cfa, Cwa). Then up north in China, along with Korea and Japan, things turn to humid continental (Dfa, Dfb, Dwa, Dwb).

A Century of Movement

Climate zones have been shifting for decades.

Take a look at this slider comparing the early 1900s (1901–1930) to right now (1991–2020).

You can see the Arctic tundra pulling away from Siberia’s coast.

Subarctic zones have retreated southward, replaced by warmer classifications moving north. Central Asian deserts have shifted their boundaries. The Tibetan Plateau has warmed, pushing some cold zones higher up. Tropical zones in Southeast Asia have seen their boundaries shift. Monsoon patterns have changed in timing and strength in some areas, affecting where climate boundaries fall.

Projections to Century’s End

For the future, I used the SSP2-4.5 scenario where emissions plateau by mid-to-late century.

Now versus the late 21st century (ssp2-4.5).

By 2099, changes come from multiple directions. Arctic tundra shrinks dramatically along Siberia’s coast, squeezed back to the northernmost strips and islands. Subarctic zones contract substantially, replaced by continental and temperate zones moving north. Desert zones in Arabia and central Asia expand in some areas. The Tibetan Plateau keeps warming, pushing cold zones to higher elevations where some just run out of mountain. Tropical zones show complex changes with some expansion and some areas drying out. Humid subtropical zones expand north in China. Continental zones in northern China and Mongolia shift toward warmer classifications.

From 1930 to 2099.

Over this span, the reorganization is huge. Siberia’s coldest zones pull back hundreds of kilometers northward. What was tundra becomes subarctic. What was subarctic becomes continental. Central Asia sees complex changes in where deserts and steppes meet. The Himalayas and Tibet lose their coldest high-altitude zones as temperatures rise. Southeast Asia’s tropical climates shift along the edges where they meet other zones. East Asia’s subtropical zones expand northward into areas that were continental.

Billions of folks rely on these climate setups. Glaciers in the Himalayas supply water to major rivers such as the Ganges, Indus, Brahmaputra, Yangtze, and Mekong, which flow across nations including India, Pakistan, Bangladesh, China, and parts of Southeast Asia. Unfortunately, these glaciers are shrinking much faster now. Regions suitable for rice farming are relocating due to evolving temps and precipitation. In Siberia, permafrost is defrosting, releasing stored ancient carbon while making the soil unstable, leading to crumbling roads, pipelines, and structures. And deserts are slowly taking over arable land.

Monsoons might hit at unexpected times or dump unusual amounts, screwing up age-old farming routines. And species? They’re struggling to adapt in time.

I also threw together some maps for 1931–1960 and 2041–2070. Full sequence here:

The post How Asia’s Climates Are Shifting: Köppen-Geiger Maps from 1930 to 2099 appeared first on Vivid Maps.

The Gulf Stream brings warm water northeast from the tropics, so London is milder than Calgary even though it is farther north. Mountains like the Alps and Pyrenees block weather systems, creating wet slopes on one side and dry rain shadows on the other. Your distance from the Atlantic or Mediterranean determines whether you get maritime moderation or the wild temperature swings of a continental interior. Latitude controls how much sunlight reaches you. Latitude affects how much sunlight you get.

These patterns aren’t staying put. I made maps showing how European climate zones have moved since 1930 and where they’re going by 2099. The data comes from Beck et al. (2023) at 1-kilometer resolution. A general northward migration is the current trend. For climate codes and their meanings, check my earlier post on global classifications.

Today’s map shows what most Europeans recognize. According to the map, Portugal’s coast is surrounded by a Mediterranean climate (Csa, Csb). Oceanic climate (Cfb) blankets Britain, Ireland, France, Western Germany, and the Atlantic-facing coasts. Northern Italy and parts of the Balkans get humid subtropical (Cfa). Central and eastern Europe from East Germany through Poland and into Russia have humid continental (Dfb). Northern Scandinavia and Russia have subarctic (Df). The Alps, Pyrenees, and Carpathians hold cool mountain climates (Cfc) with tundra patches (ET) on the highest summits. Spain’s interior plateau and areas around the Black Sea and Caspian Sea show semi-arid zones (BSk).

A Century of Northward Movement

Climate zones have been on the move for decades.

The early 1900s (1901–1930) versus today (1991–2020).

The Mediterranean climate has shifted north into southern France and expanded in the Balkans. Oceanic zones have moved into areas that used to be more continental. Humid continental climates have shifted northeast. Subarctic zones in Scandinavia have pulled back northward. Mountain tundra has retreated to higher elevations.

Projections to Century’s End

For the future, I used the most possible SSP2-4.5 scenario where emissions plateau by mid-to-late century.

Today versus late this century (SSP2-4.5).

By 2099, the movement speeds up. The Mediterranean climate extends deep into southern France and spreads into more of the Balkans and Spain’s interior. Humid subtropical zones expand northward from Italy and the Balkans toward Poland. Continental climates shift further northeast, with cooler variants pushed into areas that are currently subarctic. Subarctic zones retreat dramatically in Scandinavia and Russia. Mountain tundra disappears from all but the highest Alpine peaks. The UK and Ireland see their oceanic climate become warmer. Some southern European areas cross from Mediterranean into semi-arid steppe.

From 1930 through 2099.

Over this timespan, climate zones migrate hundreds of kilometers northward. In 1930, Mediterranean stayed on the Mediterranean. By 2099, it’s in southern France. What was oceanic becomes Mediterranean. What was continental becomes oceanic. What was subarctic becomes continental. Some areas that were Mediterranean become semi-arid as temperatures rise and precipitation patterns shift.

The coldest zones contract toward the Arctic coast or disappear. This changes agriculture, water supplies, forests, and what kinds of buildings you need. Wine regions migrate north. Forests adapted to cooler conditions struggle with heat. Rivers change when they flood. Buildings designed for one climate face another. Species that need specific conditions either lose habitat or expand their ranges.

I made maps for 1931–1960 and 2041–2070 too. The full sequence:

Data and Methods: Maps use the 1 km Köppen-Geiger dataset from Beck, H.E., et al. (2023), “High-resolution (1 km) Köppen-Geiger maps for 1901–2099 based on constrained CMIP6 projections,” Scientific Data 10, 724 (https://www.nature.com/articles/s41597-023-02549-6).

But elevation and rain shadows create exceptions. The mountains have cool-summer oceanic climate (Cfc). South Island’s Southern Alps hold patches of subarctic climate (Dfc) and even tundra (ET) on the highest peaks. Around Canterbury and into Central Otago on South Island, the mountains block enough rain to create New Zealand’s only dry zone: cold steppe (BSk). Parts of inland South Island get cold enough for humid continental climate (Dfb).

These cooler and drier zones are changing. I made maps tracking how New Zealand’s climate zones have moved since 1930 and where they’re going by 2099, using high-resolution Köppen-Geiger data from Beck et al. (2023) at 1-kilometer resolution (for climate codes and their meanings, see my earlier post on global classifications).

Today’s map shows oceanic climate (Cfb in green) covering most of both islands. This is the mild, damp climate New Zealand is known for. In the mountains, you find cool-summer oceanic (Cfc) where elevation keeps temperatures lower. The Southern Alps on South Island hold small areas of subarctic (Dfc) and tiny patches of tundra (ET) on the highest peaks. Central Otago shows the country’s only semi-arid zone: cold steppe (BSk) where the mountains create a rain shadow. Parts of inland South Island have humid continental climate (Dfb) with colder winters than the coast.

Changes Since 1930

Over the past century, the cooler and drier zones have contracted.

Comparing the early 1900s (1901–1930) with modern times (1991–2020).

Since 1930, the cold steppe (BSk) in Otago has expanded and become more pronounced. But the cool climates have shrunk. Cool-summer oceanic (Cfc) has contracted in the mountains. Humid continental (Dfb) zones have gotten smaller. Subarctic (Dfc) areas have pulled back to higher elevations.

Projections to Century’s End

For future projections, I used a more realistic SSP2-4.5 scenario.

Today’s climate versus projections for the late 21st century (ssp2-4.5).

By 2099, the changes become more dramatic. Cool-summer oceanic climate (Cfc) disappears from North Island entirely. On South Island, Cfc, Dfc, and ET all shrink substantially. Even the cold steppe (BSk) in Otago contracts. The tundra patches on the highest peaks would vanish or become extremely restricted. The subarctic zones would retreat to only the very highest remaining areas.

The full span: 1930 to 2099.

From 1930 to 2099, New Zealand loses much of its climate diversity. The cool mountain climates that create distinct ecosystems and support unique species contract dramatically.

New Zealand’s mountain ecosystems depend on these cool climates. Alpine plants adapted to cold conditions lose habitat as zones move upslope. Snow cover decreases, affecting rivers fed by mountain snowmelt. Glaciers continue retreating.
