U.N. Climate-Change Alarms Cast Little Light on Heat

This article investigates the temperature reduction impact of major climate policy proposals implemented by 2030, using the standard MAGICC climate model. Even optimistically assuming that promised emission cuts are maintained throughout the century, the impacts are generally small. The impact of the US Clean Power Plan (USCPP) is a reduction in temperature rise by 0.013°C by 2100. The full US promise for the COP21 climate conference in Paris, its so-called Intended Nationally Determined Contribution (INDC) will reduce temperature rise by 0.031°C.

Headlines from around the world tell us of hundreds of deaths caused by recent heat waves. The stories invariably blame climate change and admonish us to tackle it urgently. But they mostly reveal how one-sided climate-alarmist reporting leaves us badly informed.

The stories contain a kernel of truth: Global warming is a real, manmade problem that needs addressing. As temperatures increase, so will the frequency and severity of heat waves. But the media fail to report the full story and thus lose focus on the most effective ways to help.

Two years after the Paris climate agreement was signed, the French capital this month again attracted the world’s good and great, who gathered for President Emmanuel Macron’s One Planet Summit. In turns blasting US President Donald Trump for withdrawing from the Paris accord and telling each other that it remains on track, politicians formed a self-congratulatory huddle with celebrity campaigners and business leaders.
