Recent findings from the MIT Sloan School of Management reveal that the financial impacts of climate change are already being felt by American households. This study highlights the tangible costs incurred due to climate inaction and extreme weather events.
Impact on Household Finances
As extreme weather events become more common, Americans face rising expenses, with climate change adding hundreds of dollars annually to household costs. This comes at a time when many are already concerned about increasing food and energy prices. The research, detailed in “Who Bears the Burden of Climate Inaction?,” was published in the Brookings Papers on Economic Activity by MIT Sloan professors Christopher Knittel and Catherine Wolfram, along with Kimberly Clausing from UCLA School of Law.
“A lot of the ways in which we discuss climate now are kind of abstract and in the future — maybe these impacts happen in 2050 or 2100 — but we really wanted to emphasize that this is already occurring and it’s having negative financial implications for households,” said Wolfram.
Geographic and Economic Disparities
Expenses linked to climate change are not evenly distributed across the country. Approximately 10% of U.S. counties face annual climate-related costs exceeding $1,300 per household. Regions such as the West, Midwest, and Southeast, including wildfire-prone California and flood-prone Gulf Coast states, are particularly affected. Lower-income households often feel the financial strain more severely, as these added costs represent a larger percentage of their budgets.
“The impacts are not evenly distributed,” Wolfram said. “Where you live and your income level both play a major role in how much the costs are affecting you.”
Contributing Factors to Rising Costs
Extreme weather, rather than rising temperatures, is a significant driver of household expenses. Natural disasters, which are becoming more frequent, have resulted in inflation-adjusted billion-dollar damages, reaching approximately $1,500 per capita in recent years. These events have been linked to over 2,500 deaths in the last five years.
Christopher Knittel noted, “U.S. households are experiencing the financial effects of climate change in ways that aren’t always obvious. These costs show up across different parts of people’s budgets, and over time they can become pretty significant.”
Energy and Insurance Costs
Energy expenses have risen due to increased usage, production disruptions, and damage to utility infrastructure. From 2020 to 2024, households spent an average of $35 more annually on electricity. Higher-income households experienced larger increases, but the relative burden on lower-income families is greater. Insurance costs have also climbed, with climate change contributing to an average $360 rise in premiums from 1990 to 2023.
Wolfram commented, “I think people realize it’s harder to get insurance, but they might not tie it directly to climate, especially if they themselves haven’t experienced extreme weather.”
Government and Other Costs
Government expenses passed on to households often involve repairs to infrastructure damaged by natural disasters, averaging nearly $150 per household from 2017 to 2021. Additional factors may include rising home prices in safer areas and increased food costs due to crop damage.
These findings underscore the growing financial burden climate change imposes on households, emphasizing the need for policymakers to consider both the costs of inaction and potential solutions that mitigate these economic impacts.
