That's the number of position categories currently available for Amazon’s expanding drone research operation in Cambridge, UK, home of the famous university there. After an acquisition of a voice technology company there two years, Amazon decided to also use that base to also significantly expand its drone research in Cambridge, under its Amazon Prime Air banner. Available positions as of today include office manager, flight operations engineers, senior research scientists, software developers and more. Not much detail on how much any of these pay, but Amazon promises "an iterative fast-paced environment where you can drive innovation, apply state-of-the-art technologies to solve extreme-scale real world challenges, and provide visible benefit to end-users," we assume pitching to millennials in search of more meaning in their jobs.

The year in which China has "promised" its carbon emissions will peak, under a new accord between the US and China announced this week after some 9 months of talks. It is also the year by which China has committed to have 20% of its energy coming from "clean" sources such as wind and solar. Meanwhile, the US announced in parallel that it would set a target to reduce its CO2 emissions by 26-28% from 2005 levels by 2025, double the pace of reduction it targeted for the period from 2005 to 2020. While much of the press has been characterizing the agreement as "historic," the goals are non-binding, and as the liberal Daily Beast notes, the announcement "is largely a restatement of existing American and Chinese carbon emission trajectories, topped with a new red ribbon." In other words, the deal won’t really generate any new initiatives or changes beyond existing plans and trends.
