U.S. Geoengineering Projects — What’s Active and What’s Hidden?

🇺🇸 U.S.-Based Geoengineering Projects (2025)

Here’s a breakdown of major geoengineering projects based in the United States, from public academic research to speculative black budget programs.

✅ Known Public Projects

NOAA – Earth Radiation Budget Initiative

• Type: Government research (non-deployment)
• Focus: Solar radiation, cloud/aerosol interaction
• Oversight: Federal
• Status: Active research, no field trials

Harvard Solar Geoengineering Research Program (SGRP)

• Key Proposal: Stratospheric Controlled Perturbation Experiment (SCoPEx)
• Status: Canceled due to public backlash
• Focus: Aerosol modeling and ethics
• Funding: Private philanthropy

Project Vesta

• Type: Coastal carbon removal via olivine weathering
• Sites: Planned in New York and North Carolina
• Goal: Sequester CO₂ through enhanced ocean alkalinity

Arctic Ice Project

• Type: Arctic albedo restoration
• Method: Reflective silica microspheres on sea ice
• Status: Small-scale trials, lab simulations

U.S. DOE & National Labs

• Role: Modeling, climate simulation, aerosol physics
• Agencies: Lawrence Livermore, Oak Ridge, etc.
• No active deployment

🕵️ Could There Be Classified Projects?

There’s no public proof, but based on history and strategic interests:

• Precedent: U.S. ran weather modification in Vietnam (Operation Popeye) and other atmospheric programs (HAARP, Project Stormfury).
• Motivation: National security, disaster mitigation, weather dominance.
• Concealment: Classified funding through DARPA, CIA, or DOD could obscure such programs.

🚨 Bottom Line: While no classified geoengineering projects are confirmed, it’s highly plausible that undisclosed modeling or dual-use tests exist.
