Melanie Stansbury on Geoengineering, Cloud Seeding, and Climate Change Science

Understanding Cloud Seeding

• 💡 Cloud seeding is a technology based on the physics of clouds, aiming to make water droplets heavy enough to fall as precipitation.
• 🔬 Experimentation with introducing particles into the atmosphere to induce precipitation has occurred since the 1940s, but research on its efficacy is ongoing.
• 📊 While some studies suggest it may increase precipitation probability, more data and robust analysis are needed.

The Reality of Climate Change

• 🌍 The scientific community has a consensus that global carbon emissions have increased, leading to observable rises in global and regional temperatures.
• 📈 Data clearly shows an increase in temperature and a decrease in precipitation over the last 30 years, particularly in regions like the American Southwest.
• ⚠️ The current drought conditions are the most intense seen in recorded history, a fact supported by observational data.

Carbon as a Pollutant and EPA Regulation

• 🏭 Scientists agree that carbon is a pollutant originating from industrial activity, impacting the shared atmosphere.
• ⚖️ The EPA regulates the emission of carbon based on scientific consensus, recognizing its contribution to atmospheric changes and measurable ground effects.
• 🚫 The regulation of carbon emissions by the EPA was previously removed but is seen as crucial for addressing climate change.

Distinguishing Weather Events from Climate Change

• 💨 While individual weather events like hurricanes or atmospheric rivers are massive in scale, it's difficult to attribute them to a single entity or pollution source.
• 🌐 Climate change, however, involves a fundamental shift in global atmospheric chemistry and physics, influencing the distribution of weather events worldwide.
• 🤝 Addressing this global challenge requires international climate agreements and collective action, as pollution in one region affects the entire global commons.
