Jet contrails affect surface temperatures

Researchers found that jet contrails depress daytime-highs and nighttime-lows, mimicking the effect of ordinary clouds, with a 5-6 degree Fahrenheit reduction in daily temperature range in regions like the South and Midwest.

Africa, from a CATS point of view

The Cloud-Aerosol Transport System (CATS) instrument has provided a detailed profile of the atmosphere above Africa, revealing particles in the air at different heights. The data will help scientists model dust plumes and interactions with clouds and aerosols, improving our understanding of climate change.

Cost of cloud brightening for cooler planet revealed

A new study has found that the 'Rayleigh Jet' technique can increase cloud reflectance by 5% with minimal energy consumption, using 30 megawatts of power, about equivalent to two large ships. This method is a reversible geoengineering approach proposed to mitigate rising global temperatures.
