Other voices on climate change

“The first 50 parts per million of CO2 operates as a powerful greenhouse gas. After that, CO2 has done its job, which is why there has been no runaway greenhouse in the past when CO2 was far higher.During previous times of high CO2, there were climate cycles driven by galactic forces, the sun, Earth’s orbit, tides and random events such as volcanoes. These forces still operate. Why should such forces disappear just because we humans live on Earth?

“The fundamental questions remain unanswered. A change of 1 per cent in cloudiness can account for all changes measured during the past 150 years, yet cloud measurements are highly inaccurate. Why is the role of clouds ignored? Why is the main greenhouse gas (water vapour) ignored? The limitation of temperature in hot climates is evaporation yet this ignored in catastrophist models.

“Why are balloon and satellite measurements showing cooling ignored yet unreliable thermometer measurements used? Is the increase in atmospheric CO2 really due to human activities? Ice cores show CO2 increases some 800 years after temperature increase so why can’t an increase in CO2 today be due to the medieval warming (900-1300)? If increased concentrations of CO2 increase temperature, why have there been coolings during the past 150 years?”

“The tide on climate change is starting to turn.  The Australian government is becoming more cautious.

“It is rare to read a new book likely to make a huge difference to public opinion.  Professor Ian Plimer’s 500-page book with 2,300 footnotes “Heaven and Earth.  Global Warming: The Missing Science” is
such a book.  30,000 copies were sold in its first month.

“Plimer is not a climate change denier, because history shows the planet is dynamic and the climate is always changing, sometimes drastically.Ice Ages have come and gone and we don’t know why.  History has seen glaciers at the equator and at one time Scandinavia was under 5 kilometres of ice.  Sea levels have been 130 metres lower than today. Some consolation comes from the fact that ice sheets predominated for
only 20 per cent of the earth’s history.

“Plimer demonstrates that a considerable amount of scientific evidence has been produced to counter the still predominant view that human activity, especially through industry, has polluted the atmosphere with carbon dioxide, which will produce disastrous climate changes including a rise in temperature, a melting of the ice caps and rising sea levels.

“Contrary evidence is already changing the debate.  Australia, with its tiny economy, is no longer aiming to lead the world.  The threat of massive job losses and increasing awareness of new evidence will
provoke even greater caution in the future. Originally we were warned about the “greenhouse effect”; then it was “global warming”, followed in turn by “climate change”.  Now we talk about reducing the “carbon footprint”.  The light is dawning and 30 per cent of scientists are sceptics or deniers.

“The final question that arises is what prediction has the AGW made that has been demonstrated, and that strongly supports the theory. It appears that there is NO real supporting evidence and much disagreeing evidence for the AGW theory as proposed. That is not to say there is no effect from Human activity. Clearly human pollution (not greenhouse gases) is a problem. There is also almost surely some contribution to the present temperature from the increase in CO2 and CH4, but it seems to be small and not a driver of future climate. Any reasonable scientific analysis must conclude the basic theory wrong.”

“Global climate models are unable to produce an output that is verifiable. In other words the output can neither be proved nor disproved. What grounds do those who use these models have to refute observations made by others to the effect that there is no believable evidence of the postulated dramatic adverse changes produced by the models? … The whole climate change issue is about to fall apart. Heads will roll.”

“As the clock ticks down towards December’s historic UN Copenhagen conference on climate change, the frenzied efforts of the warmists to panic us over all that vanishing Arctic and Antarctic ice are degenerating into farce.

“That great authority Ban Ki-moon, the UN’s Secretary-General, solemnly tells us that the polar ice caps are “melting far faster than was expected just two years ago”. Yet the latest satellite information from the US National Snow and Ice Data Center (passed on by the Watts Up With That blog) shows that, after the third slowest melt of April Arctic ice in 30 years, the world’s polar sea ice is in fact slightly above its average extent for early May since satellite records began in 1979.”
