Mercurius Golstein’s letter (NDL, August 26), commenting on mining, shows that he has little understanding or knowledge of the issue of global warming and climate change.

In the past 70 years, since carbon dioxide emissions have been increasing significantly, global temperatures have increased for only 20 years (1978-1998). This increase was half a degree.
Before and after this period, global average temperatures did not change significantly, even though carbon emissions were increasing.
European countries have done the most in converting to renewable energy, but it hasn’t had any effect in reducing global carbon emissions.
There is no guarantee that reducing or eliminating carbon emissions will have any effect on global warming, but it would certainly impoverish the world, especially developing countries.
Of the 11,944 abstracts of peer-reviewed journal articles, which included the terms “climate change” or “global warming”, two thirds expressed no position on human induced global warming.
Of the remaining one third that did have an opinion, only 4 per cent responded to a request to give a more detailed opinion. Of this 4 per cent, 97 per cent agreed that climate change was real and human-caused.
Hence only 4 per cent of the authors of these peer-reviewed abstracts support the theory that human activity is causing significant climate change.
This widely used claim of 97 per cent scientific support for significant human-induced climate change is totally false.
The geological history of global warming and climate change is universally ignored by climate change alarmists.
It is known that atmospheric carbon levels were many times greater in the past than they are today, and plant life flourished at that time. Increasing atmospheric carbon dioxide will likewise benefit agriculture today.
In the past 2000 years there have been two periods when global temperatures were similar to today’s – the Roman period and the Middle Ages.
These were both periods of improved progress in human civilisation.
The use of coal for cheap energy during the past 200 years has been the major cause of lifting industrialised countries out of poverty to prosperity. It would be immoral to deprive developing countries the use of coal to improve their living standards and prosperity.
While the possible detrimental effects of global warming and increasing atmospheric carbon levels have been grossly exaggerated, the significant beneficial effects are ignored.
The money spent on the regular international talkfests on climate change would be better spent on meeting the health and nutritional needs of the world’s poor.
The world is embarking on a dangerous path in its misinformed efforts to decarbonise its economies.
