Scanning the cosmos for signs of alien technology

Physics World

While neither idea was ever implemented, both were examples of a “technosignature” or a “technomarker” – a tell-tale indication of past or present technological activity, pointing out the existence of an advanced planetary civilization. Frank is looking at what kind of signature a planet’s technology might leave in its spectra.

This Climate Debate is a lot of Hot Air

Legal Planet

We’ve been hearing a lot lately about geoengineering – the various scientific theories and governance ideas that could eventually lead to technological interventions to help cool the planet. In fact, the academic sources that this story describes as “supporters” simply support the goal of further studying geoengineering.

Why UCS Supporters Are Pressing EPA to Let California Enforce Its Truck Pollution Rules

Union of Concerned Scientists

The direct emissions of nitrogen oxides (NO X ) associated with truck pollution exacerbates asthma , and NO X leads to the formation of ozone, which shows clear evidence for reduced lung function and increased mortality. We in Colorado have many days of problematic ozone. California is leading the way, but states are ready to follow.

EPA Grant Program Helps to Accelerate Transition to Cleaner Ports

Union of Concerned Scientists

The types of projects eligible under the CPP range widely, but notably the agency is focused on already proven zero-emission technologies, like electric tractor trucks, tugboats, and cargo handling equipment. The program is squarely focused on zero-emission equipment and projects – combustion technologies are explicitly ineligible.

The agency’s air quality modeling indicates that most areas would receive an ozone reduction of less than 0.1 These air quality impacts are minimal compared with the major ozone reductions resulting from the 1998 SIP Call, which resulted in more than 80,000 megawatts of coal capacity being retrofitted with SCRs. ppb by 2025.
