No Wind of Change?

The UN has reported that there has been no sign at all that the rate of release of 'greenhouse gases' is declining (https://www.theguardian.com/environment/2019/nov/25/climate-heating-greenhouse-gases-hit-new-high-un-reports). In fact, the current levels have reached a new high for post-industrial times which, if continued, would lead to the average temperature rise doubling the arbitrary 'safe' limit (pulled out of thin air at the Paris summit) of 1.5 degrees Celsius. The finding strongly suggests that the major polluters are making little meaningful attempt to fulfil their pledges. A little urgency may be required.
