Geoengineering: ‘computer-based virtual worlds’ tell us how much sunblock Earth needs

From the Pacific Northwest National Laboratory: Earth sunblock only needed if planet warms easily Planet’s sensitivity to greenhouse gases will determine how much shading could be needed to slow temperature rise RICHLAND, Wash. – An increasing number of scientists are studying ways to temporarily reduce the amount of sunlight reaching the earth to potentially stave…

Ship sprayed seawater cloud making V2.0

Willis covered this before on WUWT, with Every Silver Lining Has A Cloud. Its baaaack. Figure 1. Artist’s conception of cloud-making ships. Of course, the first storm would flip this over immediately, but heck, it’s only a fantasy, so who cares? SOURCE From the University of Washington  and the Royal Society Experiment would test cloud geoengineering…

Texas A&M says freshwater hurricanes grow stronger

From Texas A&M University , a claim that fresh water intensifies hurricanes. At first blush, the concept seems wonky to me, as I don’t think there’s much difference between the heat content potential of fresh -vs- saltwater. Though, it might simply be that freshwater deltas have higher temperature of outflowing water to start with, exacerbated…

Linked: aerosol pollutants and rainfall patterns

From the University of Maryland Rising air pollution worsens drought, flooding, UMD-led study shows COLLEGE PARK, Md. – Increases in air pollution and other particulate matter in the atmosphere can strongly affect cloud development in ways that reduce precipitation in dry regions or seasons, while increasing rain, snowfall and the intensity of severe storms in…
