Scientists warn world will miss key climate target


Leading climate scientists have warned that the Earth is perilously close to breaking through a 1.5C upper limit for global warming, only eight months after the target was set.

The decision to try to limit warming to 1.5C, measured in relation to pre-industrial temperatures, was the headline outcome of the Paris climate negotiations last December. The talks were hailed as a major success by scientists and campaigners, who claimed that, by setting the target, desertification, heatwaves, widespread flooding and other global warming impacts could be avoided.

However, figures – based on Met Office data – prepared by meteorologist Ed Hawkins of Reading University show that average global temperatures were already more than 1C above pre-industrial levels for every month except one over the past year and peaked at +1.38C in February and March. Keeping within the 1.5C limit will be extremely difficult, say scientists, given these rises.

These alarming figures will form the backdrop to the Intergovernmental Panel on Climate Change talks in Geneva this month, when scientists will start to outline ways to implement the climate goals set in Paris. Dates for abandoning all coal-burning power stations and halting the use of combustion engines across the globe – possibly within 15 years – are likely to be set.
“If the world puts all its resources into finding ways to generate power without burning fossil fuels, and if there were international agreements that action must happen instantly, and if carbon emissions were brought down to zero before 2050, then a rise of no more than 1.5C might just be achieved,” said Dr Ben Sanderson of the National Center for Atmospheric Research in Boulder, Colorado. “That is a tall order, however.”

Action is needed – on power generation, transport, housing – but will anything be done? Will we carry on flying, driving just as we always do?
