Concentrations of key gases in the atmosphere that are driving up global temperatures reached a new high in 2017. In their annual greenhouse gas bulletin, the World Meteorological Organization (WMO) says there is no sign of reversal in this rising trend. Carbon dioxide levels reached 405 parts per million (ppm) in 2017, a level not seen in 3-5 million years. Researchers also note the resurgence of a banned gas called CFC-11.

Cooling the Earth by injecting sun-blocking particles into the stratosphere could be “remarkably inexpensive”, according to the most detailed engineering analysis to date. The fear of a rogue nation or military force unilaterally taking control of the global climate is unfounded, the researchers added, as the many thousands of high-altitude flights needed to affect global temperatures could not escape detection. The new research estimated the technology costs of putting millions of tonnes of sulphate particles high into the atmosphere. This form of geoengineering mimics major volcanic eruptions, which have significantly reduced global temperatures in the past.

A UN report has revealed that wealthy donor countries are more than $20bn short of their 2020 target to help poorer nations combat climate change, as the host of next month’s international climate summit warned that funding will be a contentious issue. Rich nations delivered about $55bn in climate-related public aid in 2016, or more than $70bn if private capital is included, according to the report seen by the Financial Times. But both figures fall short of the $100bn per year that rich countries have been promising poorer countries for nearly a decade. Michal Kurtyka, the Polish minister presiding over the summit in the city of Katowice, said funding will be one of the main sticking points in the negotiations that begin on December 3. “There is a very big debate around the issue of mobilisation of funding,” he said.
