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…
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…
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…
From the DOE/Pacific Northwest National Laboratory, a new paper in GRL saying something that doesn’t make much sense to me. As shown in the diagram above, thunderstorms transport heat from the lower troposphere upwards. The heat source at the base of the atmosphere (at the surface) is the absorption of sunlight by the surface of…
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…
From DOE/Pacific Northwest National Laboratory, probably the biggest load of crap I’ve seen in quite some time. I realize that’s harsh, and I don’t think I’ve ever used that sentence to describe a scientific study, but there’s really no other way to say it when we have massive imports of fruits and vegetables from other…
UPDATE: After I sent an email to Dr. Steve Ghan, RC has suspended comments. See below. My thanks and kudos to them for doing so. – Anthony It strikes me as very odd, and very, very, tacky, that Real Climate would run this today, especially since Dr. Spencer’s book has been out for quite some…
As most readers know, clouds are still poorly understood and under-represented in climate models. This new research may help. From: DOE/Pacific Northwest National Laboratory Effect of cloud-scattered sunlight on earth’s energy balance depends on wavelength of light Accounting for wavelength effects will likely improve climate models RICHLAND, Wash. — Atmospheric scientists trying to pin down…
From PNNL: Worldwide sulfur emissions rose between 2000-2005, after decade of decline Shipping, China top emissions growth in new analysis of 150 years of emissions COLLEGE PARK, Md. – A new analysis of sulfur emissions appearing in the journal Atmospheric Chemistry and Physics shows that after declining for a decade, worldwide emissions rose again in…
