Dr John Cameron's letter, 'Climate change report alarmism, not science' (Write Back, February 2), was useful in that it drew the public's attention to the UK Climate Change Risk Assessment Report. But his letter was recklessly useless in its comment on it.
Dr Cameron makes a number of claims about climate science, but offers no credible sources for his point of view.
The Committee of Climate Change, who publish the report, draw upon peer-reviewed scientific papers in their work. Their conclusions are based on facts and evidence. Some indisputable facts about climate change are: global temperature has increased 0.85°C since 1880, global sea level has risen an average of 0.19m in 100 years and CO2 levels in the atmosphere have increased almost 30% since 1958. The last time the CO2 levels were above 400 parts per million was four million years ago.
The impacts of climate change are severe: Arctic sea ice, glaciers and the Greenland ice sheet are melting fast; deadly heatwaves are more likely; severe flooding is increasing, for example Storm Desmond and the Paris flood of 2016 were more likely because of climate change; and climate-related disasters raise the risk of conflict such as the Syrian civil war.

I hope that, in this era of "post-truth" and "alternative facts" (ie lies), readers will be sceptical of hearsay and baseless opinion.
