Major cities with the biggest projected temperature changes by 2050tradville // Shutterstock
September 2020 was the hottest recorded month worldwide, with 2020 representing the second-hottest year ever recorded. Every one of the top-five hottest years have occurred since 2015.
From meteorologists to ecologists, researchers are closely monitoring the effects of climate change and using that data to help better predict changes to come. Chief among those effects are temperature swings: Winters and summers are expected to be warmer in virtually every city by 2050. But just how extreme those increases will be varies by location.
Nestpick ranked 20 cities facing the biggest temperature increases in the next 30 years. The rankings come from Nestpick's own study that looks at how climate change is projected to affect 85 cities around the world by 2050. Findings reveal which cities are most vulnerable when it comes to potential sea-level rise, temperature increases, water shortages, and even which income levels will be most affected. Ties were broken by the projected average annual temperature in 2050. Cities are listed from lowest temperature increase (#20) to highest (#1).
Even small average temperature increases can wreak havoc on local economies, culture, and ecology. Baked into averages are more aggressive weather events and "weather whiplash," from droughts and wildfires to heavy rainstorms and flooding. Higher temperatures mean bigger energy bills and potential for power outages, while persistent heat waves and droughts spell trouble for agriculture and fish populations.
These scenarios, while already underway, assume that fossil fuels are burned at the same rate. Mitigation efforts could avoid worst-case scenarios, while infrastructure plans in cities will help manage the effects if they should come to full fruition. Keep reading to learn more about the 20 cities globally with the biggest projected temperature increases by 2050.

The Pacific Northwestern United States is known for its mild climate. Summer high temperatures average around 72 degrees Fahrenheit, but it’s estimated that the city will see more and more 90-degree (32.2 C) days in the years to come. Heat can be deadly, particularly for the elderly—and especially in a city where infrastructure isn’t already in place to support cooling off its residents. Meanwhile, sea levels in Seattle have risen 6 inches over the past century and are expected to rise 10 more inches by 2050.

On the other side of the United States, Boston is also heating up as sea levels rise. It ranks 21st in the world for worst sea level rise, with 6 more inches expected in the next 15 years alone. The city is focusing on preparing their waterfronts by restoring marshes in waterfront parks and encouraging flood-resistant developments. It’s not totally clear why Boston and the rest of New England are slated to get disproportionately warmer under climate change, but climatologists suspect it relates to warming seas and its location related to the jet stream and Gulf Stream.

With oceans warming and glaciers melting, St. Petersburg has long been prone to floods from rising sea levels. Construction on a $3.85 billion floodgate across the Gulf of Finland was begun in 1979 to protect the historic city and UNESCO World Heritage Site from storm surges. The project was not completed until 2011 and has held since, but officials noted that the Neva Bay is freezing over later each year which increases the chance for early winter storm surges.

The first inland city to make the list, this urban center in northwest Africa is already warm and getting warmer. Rising temperatures in Morocco are expected to bring increased drought and decreases in water supplies for residents. Rainfall is expected to drop at least 18% and snow cover at least 38%, which would significantly deplete groundwater stores. Marrakesh hosted the 2016 United Nations Climate Change Conference, the first meeting after the Paris Agreement of 2015.

Top of mind in Kiev and surrounding areas is what effects warming temperatures and drought will have on agriculture. Ukraine lost an estimated 1.4 million acres of winter crops such as wheat to drought last winter, after rainfall dropped to 8% below normal. 2019 broke local records for the hottest year on record in Kiev, only to be outdone by 2020. The city broke 36 different temperature records that year, including 12 in March.

The temperature projections for Washington D.C. are expected to double, if not triple, the number of dangerously hot days the city sees each summer by 2050. Although the U.S. Capital is about 30 miles inland from the Chesapeake Bay and 100 miles from the open ocean, it borders two tidal rivers, the Potomac and Anacostia, which are susceptible to sea-level rise. The two water bodies rose 11 inches in the past 90 years, and are expected to rise 3.4 more feet by 2080. Several underground Metro rail stations already experience flooding, and above-ground transit stations are at risk from storms and extreme heat.

Budapest forms a major heat island, with temperatures in the city center averaging 2.7 degrees Fahrenheit (1.5 C) warmer than the outskirts. Temperatures have already risen by that amount since 1970, and are continuing to rise even more. The city is working on its green infrastructure in hopes that pocket parks, which increase the amount of green space per capita, will cool off the heat island as well as mitigate air pollution.

Ottawa pledged in 2020 to commit $100 million to reduce the oil and gas industry's greenhouse gas emissions by 100 megatons by 2033. The city is bracing for more heat-related illnesses in the summer, home damage and power outages from more frequent severe storms, strained sewer systems from increased rainfall, and damage to roads and other infrastructure from more frequent freeze-thaw cycles. Spring floods are of particular concern to property owners. Ottawa's government rolled out an ambitious goal of reaching zero greenhouse gas emissions by 2050.

Officials in Stockholm estimated in 2010 that a mean annual temperature shift of 4 degrees Celsius would increase total summer mortality by 5% from heat waves and increases in infectious diseases, though there may be a parallel drop in cold-induced deaths in winter as it warms. Sweden is working toward carbon neutrality, aiming for a 100% reduction in emissions by 2040. Sea levels in the Baltic Sea around Stockholm have risen, but the land has been rising just as fast as it decompresses after becoming ice-free which has kept the coastlines dry.

Like the other cities on this list, Chicago is bracing for scorching summer heat and other extreme weather events. It’s expected the area will see longer dry spells interspersed with heavy rainfall events. The city has already started planting new trees that can withstand warmer climates, installing permeable pavements to improve stormwater management, and installing green roofs and reflective roofs to cool buildings. It recently planted more than 500,000 trees over a 15-year period, and all new buildings since 2001 have had to meet the reflective roof standards.

One of the biggest climate events to get the attention of Nashville, Tennessee, residents was the flood in 2010. A record-breaking 17 inches of rainfall—13 inches in 48 hours—fell on the area, causing $2 billion in property damage and killing 11 people. Extreme rainfall patterns and flooding are expected to become increasingly common, as are high heat days during the summer months. What’s more, in a southern state like Tennessee, more warm days mean a longer mosquito season, which increases the risk of the Zika virus and other mosquito-borne illnesses.

Philadelphia expects hotter temperatures and more rainfall to be its biggest concerns in the near future. A 2015 study from the Philadelphia Department of Public Health found that some areas of the city can be up to 22 degrees (12.2 C) hotter than other neighborhoods. More precipitation means more rain in summer and snow in winter, as well as more extreme storms, hurricanes, and flooding. The city’s climate adaptation plan includes engaging citizens and support for local food networks.

The city’s Disaster Preparedness and Planning Project (DP3) was launched in 2013 to lead the efforts in creating a more resilient city. High tides already breach the popular Inner Harbor area, cutting off access to its businesses. By 2045, it’s expected these high tide flood events will be 10 times more common.

It’s been written that Cincinnati is putting forward an outsized effort in the fight against climate change, but perhaps that’s because the city is at such a high risk for rising temps. In 2020, it contracted a new solar farm that will be the largest in the country. The city is aiming for 100% renewable energy by 2035—a faster goal than even Stockholm’s 100% by 2040.

Topping this list is Ljubljana, the largest city and capital of Slovenia. It’s the fastest-warming city in the world, thanks to its topographical position in a basin that leads to weak air circulation with the surrounding landscape. The city is already rather small and loaded with green spaces, which will keep its warming from being even greater. The city government reported in 2019 that it has implemented 2,000 different projects to care for the environment, including planting 50,000 trees, energy efficient building renovations and more.

Some warm-blooded animals are experiencing shifts in their body shapes, likely as a response to the pressures of climate change, according to a new review of existing research.
Animals are getting larger beaks, legs and ears that allow them to better regulate their body temperatures as the planet gets hotter, with birds particularly affected, said Sara Ryding, a researcher at Deakin University in Australia and one of the authors of the research that published on Tuesday in the journal Trends in Ecology & Evolution.
The biggest shifts in appendage size in the more than 30 animals they looked at in the review were among some Australian parrot species, which saw their beak size increase by 4% to 10% on average since 1871.
“It means animals are evolving, but it does not necessarily mean that they are coping with climate change. We can see that some species have increased in appendage size so far, but we don’t know if they will be able to keep up as the climate crisis worsens,” Ryding said via email.
“We also don’t know whether these shape-shifts actually aid in survival (and therefore are beneficial) or not. This phenomenon of shape-shifting shouldn’t be seen as a positive, but rather it is alarming that climate change is pushing animals to evolve like this, under such a relatively short timeframe.”
She said that the changes were subtle and unlikely to be immediately noticeable but could be “functionally important.”
While climate warming was a “compelling argument” as the driving force behind these changes in shape, the study said that it was difficult to “establish causality with confidence” given the multifaceted effects climate change has on the environment.
Smaller bodies, bigger appendages
Within an animal species, individuals in warmer climates have larger appendages, such as wings and beaks — a pattern known as Allen’s rule, with the greater surface area allowing the animals to control their temperature more easily, the study noted.
At the same time, body sizes tend to shrink, since smaller bodies hold onto less heat.
In the United States, a recent study of 70,716 migratory birds representing 52 species showed that they have been getting smaller over the past four decades, and their wingspan wider. The birds all died when hitting high-rise buildings in Chicago during migration and were collected by the city’s Field Museum.
“Both of our studies look at how animals respond to climate change by altering their surface area to volume ratio,” explained Ryding.
While most research on morphological change over time has focused on birds, the paper noted that shrews and bats have increased their relative ear, tail, leg and wing sizes.
It said that more research on different species and in different ecosystems was needed to determine how wide the phenomenon was and could help predict which species might shape-shift in the future.
“Previous studies have shown cases where shape-shifting is happening, but these have focused on individual species or groups. Our review paper combines all of these to show how widespread this phenomenon seems to be,” Ryding said.
