The weather at any spot is usually defined by max/min temperatures, humidity, precipitation and wind strength/direction. Weather varies hourly, daily, season-to-season and place-to-place. These weather measurements at any place can be averaged over various time periods.
Once again, the high priests of the UN/IPCC have forecast world starvation unless we mend our wicked ways. According to them, unless we curb our use of oil, gas, coal and meat, the carbon dioxide levels in the atmosphere will soar, the globe will heat up, and food production will plummet.
A month ago an arsonist lit a bush-fire that spread into the Morwell open cut coal mine in Victoria. Residents of the nearby town lived for weeks in choking polluted air.
The Climate Change Authority wants Australians to cut their production of carbon dioxide to 19% below 2000 levels by the year 2020.
In 2007 a computer model predicted that the Arctic would be free of ice by 2013. But in 2013, Arctic ice was abundant.
Every day some place in the world has “wild weather”. And in recent times, human industry gets the blame. “It’s all caused by man-made global warming” (generally shortened to “global warming”, or GW by alarmists).
Germany’s wind and solar power generation came to a standstill late last year. More than 23,000 wind turbines ran out of wind and most of the one million photovoltaic systems ran out of sunlight. For a whole week, coal nuclear and gas-powered plants generated an estimated 95 percent of Germany’s electricity.
Apart from a tad of geothermal heat and a wisp of heat from nuclear power generators, every bit of surface energy (including coal and biomass) comes directly or indirectly from the sun. There is no other source of surface heat--- everything else just stores, releases or re-directs solar energy.
The current heatwave in Australia will inflame the carbonistas who will claim it is caused by wicked humans exhaling and exhausting carbon dioxide.
To compete in today’s world we need to score well on resource availability, capital assets, energy costs, tax burden and workforce/management. It also helps to have secure property rights and a sound currency. Today’s Australia scores poorly on all counts.
For at least fifty years, agitated academics have been predicting the end of the Great Barrier Reef. Now international “experts” are also sprouting coral calamity. But despite the alarms, the reef is still there.
