Intensive agriculture influences U.S. regional summer climate, study finds

Energy-efficient encryption for the internet of things

But that won't work in the internet of things, an envisioned network that would connect many different sensors — embedded in vehicles, appliances, civil structures, manufacturing equipment, and even livestock tags — to …

Of course, we know the fossil fuel (FF) industry is the big winner. Individuals in a climate debate, regardless of side, gain very little if anything
