Hot words on climate: Letters to editor

Climate emergency editorial

On August 7, both the editorial and a letter suggested there is a climate emergency. I beg to differ. The climate has been changing for millions of years, with extremes beyond those currently being experienced and we are still here with no adverse effects. The claim of climate alarmists is that human activity is causing big changes in temperature that will have adverse consequences. The truth is that there has been an average (which is meaningless) increase in temperature of 1 degree C over the last 100 years which we, including those of us of advanced years, have not really noticed. Another 1 degree increase over the next 100 years will similarly pass with us being unaware and no adverse consequences. The claim that human activity, particularly the burning of coal, is predominantly responsible for temperature change is wrong. Human activity contributes only 3% of the total CO2 in the atmosphere and has negligible effect. As a scientist I refute the claim by your correspondent that 99 per cent of scientists world wide agree we are in a climate emergency. Wrong.
