ENERGY A DRIVER OF OUR CLIMATE

The earth-atmosphere energy balance is achieved as the energy received from the Sun balances the energy lost by the Earth back into space. In this way, the Earth maintains a stable average temperature and therefore a stable climate. You have learned that Earth’s surface absorbs and emits radiation at the same rate. This balance in the […]

EARTH TEMPERATURE FOREVER 59 F

One of the scientists, Dr. James E. Hansen of the National Aeronautics and Space Administration’s (NASA) Institute  for Space Studies in Manhattan, in 1988, said he used the 30-year period 1950-1980, when the average global temperature was 59 degrees Fahrenheit, as a base to determine temperature variations. This was remarkably accurate given the state of […]

THE NET ZERO NATURAL GAS PLANT

Included in a group of technologies known as carbon capture and sequestration (CCS), zero-emission fossil fuel plants have been a dream never realized in practice, adding between 5¢ and 10¢ per kWh. This is probably because most attempts just add on another step after the traditional electricity generation steps, almost as an afterthought. But this […]

PEDESTRIAN CROSSING WAS AXED

The four corner elevated circular cycling and pedestrian crossing was to be built at the intersection of Doncaster Road/Williamsons Road/Tram Road, designed by Manningham Council, to maintain traffic flow and to link directly to the Westfield expansion and the public transport interchange located to the north. The overpass was an outstanding concept in design at […]

THE ATMOSPHERE ENERGY BALANCE

The earth-atmosphere energy balance is achieved as the energy received from the Sun balances the energy lost by the Earth back into space. In this way, the Earth maintains a stable average temperature and therefore a stable climate. The average surface temperature of the moon, which has no atmosphere, is 0°F (-18°C). By contrast, the […]
