How we did this

This Pew Research Center analysis focuses on public opinion of climate change and its effects in nine middle-income countries. Opinions surrounding climate change are examined in the context of long-term trend data.

This analysis draws on nationally representative surveys of 12,375 adults conducted from Jan. 8 to April 21, 2025. Surveys were conducted face-to-face in Argentina, Brazil, India, Indonesia, Kenya, Mexico, Nigeria, South Africa and Turkey.

For the purpose of comparing educational groups across countries, we standardize education levels based on the United Nations’ International Standard Classification of Education (ISCED). The lower education category is lower secondary education or below and the higher category is upper secondary or above in middle-income countries (as defined by the World Bank).

Here are the questions used for this analysis, along with responses, and the survey methodology.

A new survey of nine middle-income nations finds widespread concerns about climate change. Large majorities in these countries say global climate change is affecting the area where they live. In the three Latin American nations polled, around half of adults or more say it is affecting their community
a great deal.

Most people in these countries also say they are willing to make at least some adjustments to the way they live and work to reduce the effects of climate change. And most have at least some confidence in the international community to address this issue.

Impact of climate change

A median of 56% of adults across nine middle-income countries say they are very concerned that global climate change will harm them personally in their lifetime. About six-in-ten or more hold this view in Argentina, Indonesia, Kenya and South Africa, compared with about a third in Turkey.

While many continue to express concern that climate change will harm them personally, the share saying this has decreased since 2015 in Argentina, Brazil, India, Mexico and Nigeria. Concern is up, on the other hand, in Indonesia (+18 percentage points), South Africa (+13) and Turkey (+7). Opinion is largely unchanged in Kenya.

When asked which of four possible effects of climate change concerns them most, respondents named droughts or waters shortages more than twice as often as any other option. Fewer say long periods of unusually hot weather, floods or intense storms, or rising sea levels concern them most.

Since 2015, the share pointing to droughts as their biggest concern is up in Indonesia, Mexico, South Africa and Turkey.

Dealing with climate change

Most people across the middle-income countries surveyed – a median of 80% – are willing to make at least some changes to how they live and work to help reduce the effects of climate change. A median of 18% say they would be willing to make only a few or no changes at all. The shares saying they would make a lot of changes range from 17% in Turkey to 53% in Kenya.

And most – a median of 62% – express confidence in the international community’s ability to significantly reduce the effects of climate change. Seven-in-ten adults or more in India, Indonesia and Kenya have at least some confidence that the actions of the international community will reduce effects of climate change. But around half or fewer agree in Argentina, Mexico and Turkey.

One major international actor is the United Nations, which has been targeting environmental issues since the 1970s. In six of the nine middle-income countries surveyed, people with a favorable view of the UN are more likely than those with an unfavorable view to have confidence in actions taken by the international community.

We also asked people which factor should matter more in deciding a country’s responsibility to address climate change: its wealth or its carbon emissions. A 59% median say carbon emissions are the more important consideration. On balance, this is the most common view in every country except Turkey, where opinion is divided.

Young adults more willing to make lifestyle changes to reduce climate change

Age is a factor in views of the impact of climate change and how to handle it. Across most of the nine middle-income countries, younger people (ages 18 to 34) are more likely than older people (ages 50 and older) to say they would be willing to make some or a lot of changes to the way they live and work to help reduce the effects of climate change.

Young adults in India, Indonesia, Turkey and Mexico are also more likely than older people to be concerned that climate change will harm them in their lifetime.

(In India, older adults were less likely to provide a response on both questions.)

In five countries, younger people are more likely than older people to say the amount a country contributes to carbon emissions should matter more than how wealthy a country is in deciding what to do to address climate change, though older adults in these countries are less likely to provide an answer.

At the center of the conflict between Big Tech and Big Auto is CarPlay Ultra, the newest version of the popular CarPlay system that can mirror a user’s iPhone interface on a screen within a vehicle. Announced earlier this year, CarPlay Ultra is going a step further by also displaying car functions like fuel level and speed. It also lets drivers control the air conditioning, radio, and driving modes, all from the same screen. Aston Martin is the only automaker that has fully integrated CarPlay Ultra into its vehicles.

While Ford is committed to Apple, CEO Farley said “We don’t like the execution of Ultra in round one.” 

“I’ve talked to Tim [Cook] many times about this. Ford does not have the right, in our opinion, to disrupt someone’s digital life when they get in their car,” Farley told The Verge in an interview.

Farley later said Apple needs to make a decision on how much it wants to encroach into a vehicle’s systems. Giving an outside company power over a car’s mechanics could be a slippery slope, he added.

“How far do you want the Apple brand to go? Do you want the Apple brand to start the car? Do you want the Apple brand to limit the speed? Do you want the Apple brand to limit access?” asked Farley.

The conflict over Apple CarPlay heated up earlier this year when GM CEO Mary Barra said the company’s future vehicles would no longer support Apple CarPlay or its Google counterpart, Android Auto. The company first began phasing out compatibility for both systems in its EVs in 2023. 

Since the release of CarPlay Ultra, other automakers, including Audi, Mercedes-Benz, Polestar, Volvo, and Renault, currently have no plans to integrate the new system into their cars, the Financial Times reported, despite Apple touting them as committed in a 2022 WWDC announcement. 

Carmakers are in a tough spot as Apple CarPlay and Android Auto are considered must-haves for many new car buyers, according to preliminary data from research firm AutoPacific. A McKinsey report from 2023 found that 85% of car owners who had CarPlay or a similar system preferred it over the carmaker’s operating system.

Still, the data hasn’t yet persuaded carmakers enough to give up control of the dash. Mercedes introduced its own Mercedes‑Benz Operating System (MB.OS) that combines infotainment and car functions. Other car companies like Toyota and Volvo are also developing their own systems, according to the Daily Mail.

Whatever Ford ultimately decides on CarPlay Ultra, it is clear to Farley that a car’s digital experience is quickly becoming one of its most important specs.

“The difference between car companies where you have a software-defined vehicle is not going to be what your sheet metal looks like. It won’t be how powerful your EV motor is. That’s all math. All the cars look nice. It’s going to be this digital experience that says why someone buys this or that,” he said.
