Climate change denial won’t even benefit oil companies soon | The Guardian

The damage caused by our addiction to burning fossil fuels will be so widespread that nobody stands to gain

he year 2018 is on track to be the fourth warmest on record, beaten only by 2016, 2015 and 2017. In other words, we have had the warmest four-year run since we started measuring. According to data from the US National Oceanic and Atmospheric Administration (NOAA), June 2018 is the 402nd consecutive month with temperatures above the 20th-century average. The UK’s Environmental Audit Committee has warned that we could see summer temperatures reaching 38C by the 2040s, leading to a potential 7,000 heat-related deaths a year.

One hot summer does not a changing climate make, but the trend in the global data is now irrefutable. When Michael Mann published the “hockey stick” graph back in 1998, there was vociferous public pushback, yet the observed temperature rises match what Mann had predicted. Today’s hockey stick graph isn’t a forward projection but a historical record. The world has been getting hotter, and it will continue to do so. The only question now is how much hotter it gets.

The mechanisms behind this are not difficult to understand. Over a period of millions of years, carbon became trapped in deposits under the Earth’s crust, as coal, oil and natural gas. As the great engines of industrialisation came online across the planet, humanity developed an insatiable hunger for this trapped carbon. Burning it powered the machines that drove economic growth and development, which in turn raised the demand for more machines and more carbon. Carbon that took millions of years to trap has been released into the atmosphere at a rate that is, in geological terms, almost instantaneous.
