P J House (Letters, 20 June) is not correct to call climate change a “fairy story”.
Side issues of our naturally variable weather and the extent to which natural cycles and the sun’s varying output affect our climate do not alter the scientific facts.
Burning fossil fuels puts carbon dioxide into the atmosphere, carbon dioxide is a greenhouse gas which traps heat from the sun that would otherwise radiate back into space (a phenomenon known since the 19th century) and more heat means higher temperatures.
If this science is wrong, we will have spent some unnecessary money, but if P J House is wrong the costs of coping with the resulting climate chaos will be immeasurably larger.
ANGELA COTTON, Southampton.
