Case study

Connecting the dots on climate change

The power of local media in reaching audiences and driving awareness on climate change during extreme weather events

Introduction

Understanding local media’s reach during extreme weather events

Nielsen collaborated with Climate Central, a policy-neutral non-profit climate science organization, to assess the presence of accurate and informative climate reporting in local media to engage communities affected by extreme weather events.

Objective

Highlight local media’s role in driving climate change awareness

According to the American Meteorological Society, local weather broadcasting is extremely effective in raising awareness about climate change. Climate Central collaborated with Nielsen to analyze local TV newscasts for climate change content and measure the audience reach associated with those broadcasts.

Challenge

Engaging local media stations to educate audiences about climate change

Despite increasing public concern about the link between climate change and extreme weather, only 28% of people in the U.S. say they hear about global warming in the media at least once a week. This suggests that media, including local media, frequently misses opportunities to increase public understanding and awareness of extreme weather and climate change.

Solution

Create a climate content metric for reports using audience reach and context analysis

Using Nielsen Local TV View (NLTV), Nielsen Grabix and the PPM Analysis Tool, Nielsen analyzed local television news and radio coverage in the top 50 U.S. DMAs related to four extreme weather events from 2022-2023 that could appropriately be connected with climate change. These events were Hurricane Ian, the Canadian wildfires, the Phoenix heat streak and Tropical Storm Hilary. The data was used to understand if, when and how coverage discussed the event in the context of climate change and was turned into a public report detailing viewership and content analysis of local TV news segments during those four notable extreme weather events.

Key findings

17M

Total reach

Broadcast segments during extreme weather events have high reach and impact. Nationwide, over 17 million people in the Top 50 DMAs were exposed to segments connecting the extreme weather event to climate change.

48%

Understand segments

Extreme heat was most often connected to climate change. About 48% of all climate contextualized segments were about the Phoenix heat streak of 31 days of >110℉ temperatures.

395%

Increased reach

During Hurricane Ian, the average reach for local news streaming apps in Orlando among people ages 25-54 increased 395% over the previous week. Local TV viewership also had exponential increases, doubling in the Orlando market for Hurricane Ian and in Los Angeles for Tropical Storm Hilary.

Results

The Climate Content Analysis proved the value and opportunity of climate reporting

This collaboration resulted in a climate content analysis used to assess the presence of climate contextualization in local TV coverage of extreme weather, meeting the public’s growing appetite for accurate information on the causes and impacts of extreme weather.

Conclusion

Nielsen’s content analysis unlocks local media programming insights during extreme weather events

Nielsen’s audience and content analysis tools powered the creation of a new metric that sets the standard for assessing climate reporting in media. This metric identifies where local media stations can provide clear weather reporting to increase awareness about climate change and its links to extreme weather events.

Nielsen’s data, and the content analysis it generated, delivered critical insights into how local media provides the public with vital information needed to help communities prepare and stay safe during times of extreme weather.
