> [!important] Interaction with [[marshallpittman]]
> - **Oct 27–29, 2026:** Marshall bookmarked the methane post and wrote **12 replies** in its thread, all aimed at **@JrmeBrwnCt** (who had answered Wielicki "Happer proved you wrong"). The first 11 also tag @MatthewWielicki. First reply, Oct 27, 3:20 PM CT: "Cryptic posts with no explanation (and thus, no relevance)."

## Identity
- **Display name:** Dr. Matthew M. Wielicki · **Handle:** [@MatthewWielicki](https://x.com/MatthewWielicki) · **User ID:** 1324336290159071232
- **Bio (verbatim):** "Director - United States Global Change Research Program (@usgcrp), husband, father, Polish immigrant, https://t.co/oHJwRZwFmu (Personal account not official)"
- **Joined:** Nov 5, 2020 · **Location (profile):** United States · **Verified:** blue check
- **Public role:** appointed in July 2026 to direct the **U.S. Global Change Research Program**, which coordinates federal climate research and produces the National Climate Assessment ([Politico, Jul 9](https://www.politico.com/news/2026/07/09/the-administration-has-a-new-climate-change-office-its-headed-by-a-climate-critic-00990916); [Washington Post, Jul 10](https://www.washingtonpost.com/climate-environment/2026/07/10/white-house-appoints-climate-science-critic-lead-key-climate-program/); [Eos](https://eos.org/research-and-developments/a-climate-skeptic-will-oversee-the-national-climate-assessment)). Coverage describes him as a climate-science critic. On Sept 21, 2026 Rep. Zoe Lofgren asked OSTP to remove him, arguing the statute requires a permanent federal employee (from an earlier search summary ⚠️).
- **Background:** PhD geochemist and former University of Alabama geology professor who now writes the "Irrational Fear" Substack ⚠️ (background from memory, not re-checked this run).

| Theme | Items | Likes | Views |
|---|---:|---:|---:|
| Feuds and replies to critics | 16 | 35 | 5,589 |
| Energy: oil, gas, coal, nuclear, hydrogen | 13 | 1,051 | 24,619 |
| Climate-claim rebuttals | 7 | 492 | 13,688 |

| Methane and greenhouse physics | 4 | 512 | 25,148 |
| "On this day" weather history | 4 | 62 | 5,836 |
1. **Feuds and replies to critics.** Short replies, often sharp, in threads such as his Oct 26 exchanges with meteorologist @ChrisGloninger. Low reach each.
2. **Energy.** Defending oil and gas profits ("Exxon and Chevron earned $26.5 BILLION in three months…", Oct 26, 322 likes), skepticism of hydrogen (JCB engine post, Oct 26, 287 likes), and reposts of the Energy Department and Energy Secretary Chris Wright on coal and the Palisades nuclear restart.
3. **Climate-claim rebuttals.** Graphs and comments arguing that warming, wildfire or extreme-weather claims are overstated.
4. **Politics and media.** His top post in the sample answered Bernie Sanders ("Bernie, just FIVE of these companies employ roughly ONE MILLION people worldwide…", Oct 24, 476 likes).
5. **Methane and greenhouse physics.** The analyzed post (474 likes, 23K views, the most-viewed item in the sample) and his "Super pollutant?" reply to the NYT.
6. **"On this day" weather history.** Historical heat, cold and storm records, posted as context against attributing events to climate change.
**Style.** Confident, short, often sarcastic replies; longer posts read like lecture notes. He often cites a chart without a source. He posts heavily: 66,016 lifetime posts since Nov 2020 is about 30 a day.
## Fact-check scorecard (this project)
| Post | Verdict |
|---|---|
| [[Users/@MatthewWielicki/Post Analyses/Post Analysis - MatthewWielicki on Methane and Water Vapor Saturation (2026-10-27)\|Oct 27: methane and water-vapor saturation]] | ❌/🟡 misleading. Methane band misplaced at 10 µm; overlap is real but forcing is 0.54 W/m² (AR6) and even Happer gets +0.7–0.8 W/m² for a doubling |

## Gaps
- Only 50 timeline items (Oct 24–30, 2026) were sampled from 66,016 posts.
- Earlier Wielicki threads Marshall may have joined were not searched.
- Background details (Alabama career, Substack) are from memory ⚠️; the Lofgren letter is from a search summary, not re-read.
