Prof. Katharine Hayhoe engagement report
@KHayhoe - 225K followers on X
Measured over 10 original posts from a 30-day window, last computed on October 2, 2026.
Engagement
A typical post picks up 182 interactions against 225K followers, an engagement rate of 0.081%. Measured over 10 original posts, its engagement rate beats 55% of 20,444 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 5.1K times each, and 3.57% of those impressions turn into an interaction. That is about 2.27% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.43 posts a day over the last 30 days, though only 37% of days saw any activity at all. Most posts go out around 15:00 UTC, and Wednesday is the busiest day of the week. Of the 10 posts sampled, 60% carry an image or video and 100% link out. The account's strongest tracked post pulled 10K interactions, about 47x its own typical post.

Compared with accounts its own size
Prof. Katharine Hayhoe's engagement rate beats 55% of the tracked X accounts closest to it in follower count (20,444 accounts, accounts of similar size (decile 9 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 79% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.
Where this sits in the catalog
At 0.081%, Prof. Katharine Hayhoe sits above the 25th percentile of the 205,782 accounts in this comparison. That places it in the below the median band, which runs 0.024% to 0.143%.

Posting timing
This account posts most often around 15:00 UTC, and Wednesday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 60% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 100% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 60% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 100% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts, so a large share of this account's output sits in the weakest bucket we measure.
- Its average post runs 792 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

This article says climate change is “believed to have played a role” in the UK's extreme heat this week. As a climate scientist, let me fact-check that. First, climate change is not a religion. No belief is required. It is about evidence. And the evidence has been crystal clear for more than two decades: climate change is making heat waves hotter, longer, more frequent and more dangerous. In fact, science has advanced far beyond saying climate change merely “played a role.” Today, we can quantify how much more likely and how much hotter climate change made a specific event. Here's the bottom line: Climate is changing. Humans are responsible. And we are experiencing the impacts now. That’s the bad news. The good news is that solutions already exist, and the majority of people care - 89%, around the world! But meaningful action depends on helping people understand not just what is happening: we need to know how it affects our lives (this heat wave being example A today) and what we can do about it. That’s the opportunity this reporting missed. https://t.co/vYfPDKcWWf

Climate change is canceling July 4 celebrations. Philadelphia, the birthplace of American independence, just called off its 250th birthday parade because it's too hot to march. Yesterday tied Philadelphia's all-time record of 103°F and with humidity, it feels like 118°F there right now, according to AccuWeather. First, organizers shortened the route; then they moved up the start time before finally sending out the notice overnight. (Floats alone were allowed to drive down the street, and Historic District venues have stepped up and are hosting as many events indoors as they can.) In DC, the Great American State Fair has closed until 5pm due to extreme heat. Heat waves aren't new. But I'm a climate scientist, and I can tell you heat waves like this are virtually impossible without fossil fuel pollution. Not only that, but when extreme weather hits, research shows that connecting it to climate change helps people understand why it matters. And you know who the most trusted people to do that are? Not scientists. You! Yes, people we know are the most effective messengers to have these conversations. So if you're worried about what's happening and how extreme heat puts us at risk -- talk about it! https://t.co/hvQCeplmeW

Hi 👋 I'm a climate scientist and notorious troll blocker. And whenever extreme heat hits, the same comments show up: “It’s just summer.” “It’s been hotter before.” “Just tough it out.” In this episode of Cold Facts, Hot Takes, I take on the myths and explain what the science actually says about today’s heat waves.

I've heard thousands of climate denial arguments over the last few decades. But do you know they all fall into one of 5 categories? 1. Climate isn't changing 2. Humans aren't responsible 3. The impacts aren't bad 4. We can't fix it 5. It's fake Too often we get encouraged when someone goes from category 1 to 2; or 2 to 3; or even 3 to 4. At least they admit it's real and human-caused, we think! But I don't get encouraged. Because I know that every type of argument above has the same goal: to delay climate action as long as possible. The only way forward is to abandon this list entirely. If someone brings up an argument, answer it briefly then pivot immediately to how climate solutions will give us a better future, and we all want that. https://t.co/FXXewiFFto

The headlines this summer make it easy to feel as if nothing can be done: record heat and wildfires continue, while fossil fuel companies rake in billions. But feeling powerless is exactly the trap, and this week there's new science on how to avoid it. Read on! 🧠 Good news: Watching a short "prebunking" video helps people across the political spectrum spot debilitating climate doom for what it is, and share it less. 🛢️ Not-so-good news: The same fossil fuel emissions driving this summer's heat and wildfires are making their producers richer than ever, with Oxfam projecting that six major oil companies will earn a combined $45 billion in Q2 of 2026, nearly double their Q1 earnings. 🗣️ What you can do: Use your voice: talk about the unfairness at the heart of this story, where a handful of companies earn billions while families pay through higher bills, lost work, and worse health. When we change social norms, we activate societal tipping points. Your voice is more powerful than you think 💚 https://t.co/32mnJwLnzw

I never expected one class to redirect my life. But that’s the thing about curiosity: you never know where one question will lead, do you? I took a class on climate change to fulfill a breadth requirement - and was surprised to learn that climate change isn’t just an environmental issue. It affects our health, our future, and every aspect of our lives. I also learned that while climate change affects us all, it doesn’t affect us equally. Those who’ve done the least to cause it bear the brunt of its impacts, and that’s not fair. We need to fix that: so that’s why I became a climate scientist & why I’m joining @MIT for #CuriosityOnAMission. We need scientists to keep asking big questions, and university science helps make that possible. Visit https://t.co/c1Ogox4NmE for more. #CuriosityPartner #sponsored

For the first time on record, solar generated more electricity than coal across the entire U.S. - despite active federal policy pushing the other direction. ☀️ Good news: The UK shut off its last coal plant in 2024. China now installs more wind and solar annually than the rest of the world combined. And last month, the U.S. crossed a milestone that seemed impossible five years ago: solar beat out coal on the national grid, for the first time in history. 🌡️ Not-so-good news: A super El Niño is set to supercharge heatwaves, droughts, and floods in the coming year. These in turn impact everything from coral bleaching risks to food price spikes worldwide. 🌈 What you can do: Find the warming stripes for your city at Show Your Stripes, share them, and use them to start one conversation.

- What is Prof. Katharine Hayhoe's engagement rate on X?
- Prof. Katharine Hayhoe (@KHayhoe) has an engagement rate of 0.081%, based on the median interactions across 10 original posts from the last 30 days against 225,025 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.081%, Prof. Katharine Hayhoe sits above the 25th percentile of the 205,782 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @KHayhoe have real engagement?
- Its engagement rate beats 55% of the tracked X accounts closest to it in follower count (20,444 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @KHayhoe post?
- Most posts go out around 15:00 UTC, and Wednesday is its busiest day, at roughly 0.43 posts per day across the measured window.
