These findings show how extreme weather can spark bottom-up political engagement—even in authoritarian settings.

Incorporating citizen perspectives can strengthen adaptation policy—especially where top-down, technocratic approaches (e.g., costly but ineffective “sponge city” pilot) dominate.

Concern over the flood and disaster preparedness spilled over beyond Henan—prompting petitions in unaffected provinces that explicitly referenced the 2021 Henan flood.

9/10

The 2021 Henan flood stands out for the scale of destruction—and its political aftermath.

Other major, but less devastating, floods did not trigger comparable surges in adaptation-related petitions on the LLMB.

Topic modeling shows that appeals focused on concrete, localized vulnerabilities—demands that weren’t framed as “climate” issues but were functionally aligned with adaptation.

7/10

Using a dynamic DiD model, I find a sustained rise in adaptation-related requests in Henan.

These estimates are likely conservative, given:

1️⃣ Spillover effects in other provinces
2️⃣ Concurrent but less severe flooding elsewhere

6/10

The flood triggered a sharp rise in climate adaptation petitions across Henan—a surge that persisted for months.

The 2021 Henan flood was among the deadliest floods in recent 🇨🇳 history.

Official source found that anthropogenic climate change increased rainfall intensity by 7.5%: doi.org/10.1016/j.sc...

In authoritarian regimes, public sentiment carries less direct political weight.

But state-sanctioned petition platforms can still channel bottom-up pressure.

This study focuses on one such system: China’s Local Leaders’ Message Board (LLMB).

Why study the Global South and authoritarian regimes?

1️⃣ They face acute climate risks but often lack capacity and resources.
2️⃣ The focus has largely been on politicians and bureaucrats—not citizens.
3️⃣ Studies on public response often rely on commercial social media and are mainly descriptive.

We conduct an extensive set of robustness checks—see the full paper for details.

Although the empirical case is situated in an authoritarian context, the theory should be applicable to democratic settings as well.
