Climate Change – What Does the Science Say?
Climate change is widely accepted as an issue, but it is not always intuitive. How is a substance as invisible and harmless as Carbon Dioxide (CO2) able to wreak havoc on earth at a scale being claimed – after all, is CO2 not what we naturally produce when we breathe, and what fuels the existence of the beautiful greeneries of the earth? If the reports from a few months ago claim that we are headed towards some of the hottest heatwaves Britain has seen, how, then, are we experiencing one of the coldest winters in recent years? Yet, climate change is an issue that has been well-understood by the scientific community for decades; it is the nuances that are difficult to communicate. These nuances are often lost in headline statements such as ‘keeping 1.5 ˚C within reach’ or ‘reach net-zero by 2050,’ fuelling much scepticism, or rather a lack of urgency, among the public. This article aims to inform the reader of the key concepts underpinning climate change science and clarify common misconceptions.
