What Effect Will Climate Change Have on The Economy?
Takeaway: By studying millions of Americans who permanently relocate across different climate zones, researchers found that warmer temperatures reduce worker earnings far less than leading climate-economy models predict.
Key Points
Short-term shocks vs. long-term climate: Traditional climate models often infer future economic damage from temporary weather spikes, which overstate long-run harm because they ignore human adaptation.
Minimal wage penalty: Workers who move to locations that are 1°C warmer see wage gains that are only 0.14% to 0.18% lower—an effect an order of magnitude smaller than existing low-end estimates of climate damage.
Taxes and amenities explain the gap: Once take-home pay (after taxes) and workers' preference for warmer weather are accounted for, the tiny wage penalty largely disappears.
How much will climate change drag down future economic growth? Estimates among economists vary wildly. Some models predict modest losses of roughly 2% of GDP per degree Celsius of warming, while other recent studies project staggering drops of up to 20% per degree.
The difference is enormous: one scenario implies a brief pause in growth, while the other implies a severe collapse in living standards.
A core challenge in measuring climate damage is accounting for adaptation. If an unexpected heatwave hits a town today, factory output might temporarily plunge because workers and buildings are unprepared.
But if a region warms gradually over decades, businesses install air conditioning, adjust work hours, and alter supply chains. Inferring the cost of long-term warming from short-term weather shocks is like judging a city's economic potential based on how poorly it functions during a sudden, unexpected snowstorm.
Research
To isolate permanent climate exposure from temporary weather disruptions, economists Jonathan Berk, Jules van Binsbergen, and Cem Kozanoglu studied American workers who permanently moved between U.S. states and metropolitan areas.
Using U.S. Census job-flow data linked with National Oceanic and Atmospheric Administration (NOAA) climate records from 2000 to 2023, the researchers tracked millions of workers changing jobs within the same industry. Because moving across states exposes a worker to a permanent shift in temperature—often spanning differences of 5°C to 15°C—their subsequent pay changes offer a direct window into how climate impacts individual labor productivity.
Findings
The researchers found that while changing jobs generally raises a worker’s pay by about 9%, moving to a warmer destination yields a slightly smaller wage bump than moving to a cooler one. However, the effect is remarkably small: relocating to a location that is 1°C warmer is associated with a wage increase that is only about 0.14% to 0.18% lower.
Applied to global warming projections, a 2°C increase in temperature would imply a productivity loss of less than 0.5% of GDP—a figure far below the 4% to 40% drops suggested by traditional models. Furthermore, when the authors evaluated take-home pay after adjusting for state and federal income taxes, this tiny wage penalty vanished completely, as many warmer U.S. states feature lower income tax rates.
Limitations and Context
The authors note that wages reflect multiple economic forces beyond pure productivity, including worker preferences and local amenities. Americans consistently demonstrate a "revealed preference" for warmer climates, voluntarily moving toward milder weather.
In labor economics, attractive amenities lead to lower wages because workers are willing to accept slightly less cash in exchange for a more pleasant environment. Consequently, the small negative wage gradient observed in the data likely acts as an upper bound, meaning the true impact on pure worker productivity is even closer to zero.
Why It Matters
These findings do not suggest that climate change is harmless, nor do they measure total environmental damage, such as sea-level rise or severe storm destruction. However, they strongly indicate that direct drops in local worker productivity are not the primary driver of major economic vulnerability.
For policymakers and business leaders, this research demonstrates that assuming heat inherently destroys workplace output overstates long-run economic damage, highlighting the crucial role that human adaptation plays over time.

Economic Concept: Compensating Differentials
A compensating differential is an adjustment in wages that offsets the non-monetary characteristics of a job or location.
If a job involves unpleasant or dangerous conditions—such as high-altitude construction—employers must pay a wage premium to attract workers. Conversely, if a city offers highly desirable non-financial perks—such as mild winters, natural beauty, or rich cultural amenities—workers are often willing to accept lower pay to live there.
When analyzing geographic pay differences, economists must distinguish between low wages caused by poor worker productivity and low wages resulting from desirable local amenities that workers are happy to enjoy.
