Study projects net cooling of climate from ship emissions through 2050

Green Car Congress

A recent study by an international team calculated that shipping causes a net cooling of climate across all parametrizations of the indirect aerosol effect (IAE) and scenarios throughout the period 1900?2050. Shipping-induced global temperature change in 2050 using different parameterizations of Indirect Aerosol Effect (IAE).

How Ted Hoff Invented the First Microprocessor

Cars That Think

Soon Mazor, then a research engineer at Intel, joined him, and the two pursued Hoff’s ideas, developing a simple instruction set that could be implemented with about 2000 transistors. The Intel marketing department they estimated that sales [of microprocessors] might total only 2000 chips a year. You’re crazy.” But word went out.
