Albedo modification (AM) is sometimes characterized as a potential means of avoiding climate threshold responses, including large-scale ice sheet mass loss. Previous work has investigated the effects of AM on total sea-level rise over the present century, as well as AM's ability to reduce long-term (Gt103 yr) contributions to sea-level rise from the Greenland Ice Sheet (GIS). These studies have broken new ground, but neglect important feedbacks in the GIS system, or are silent on AM's effectiveness over the short time scales that may be most relevant for decision-making (<103 yr).
Geo-engineering schemes like reflecting solar radiation or sucking CO2 out of the sky will not be a feasible way to reduce emissions for the next several decades, a new EU-funded report has warned.
Urban agriculture requires local water to replace 'hydrologic externalities' associated with food produced outside of the local area, with an accompanying shift of the water footprint (WF) for agricultural production from rural to urban areas. Water requirements of urban agriculture have been difficult to estimate due to the heterogeneity of shading from trees and buildings within urban areas.

In this paper, we investigate the coagulation of interstitial aerosol particles (particles too small to activate to cloud droplets) with cloud drops, a process often ignored in
Australians no longer believe a tan is something to aspire to, but too many still get sunburnt and put themselves at risk of potentially deadly skin cancers, the Cancer Council says.
Around 30 million cases of skin cancer will be prevented by 2030, thanks to successful implementation of the Montreal Protocol and its amendments says this new report produced by the Environmental Effects Assessment Panel (EEAP) of the Montreal Protocol. The report details various effects of UV radiation on human health, ecosystems, biogeochemical cycles, air quality and materials.
