Opinions v facts
CLIMATE alarmist Ken Moore said current climate changes are unprecedented and quotes the ice cores as evidence (Gatton Star, 7/10).
He has obviously not checked the ice core records. These show clearly that current temperatures and sea levels are not extreme and are more stable than they were as the last ice age ended just 12,000 years ago.
At that time, global temperature increased quickly, the great ice sheets melted, sea levels rose rapidly (130 metres), and the warming seas expelled much of their dissolved carbon dioxide into the atmosphere.
As a result of this natural global warming and the additional moisture and carbon dioxide plant food in the atmosphere, plant life recovered and the great forests and grasslands were re-established.
Not one coal-fired power station, diesel truck or feedlot of belching bovines contributed to those massive climate changes; and resident witch-doctors were unable to prevent flooding of coastal settlements with human sacrifice. Then, as now, nature ruled the climate.
More recent evidence from ice cores, sediment layers and even historical records show that for the last 7000 years Earth’s climate has been relatively stable.
Even more recently, satellite records show that global temperatures have not risen significantly for nearly 20 years and the tide gauges surrounding the Pacific show that sea levels are barely rising. Our climate is NOT changing rapidly, no matter how many alarmists repeat it.
Just one stubborn fact or careful observation will beat 97 opinions.
Ken should heed Senator Moynihan’s advice: “You are entitled to your opinion. But you are not entitled to your own facts”. Viv Forbes, Rosewood
