BRUSSELS, June 1 (Reuters) - The outcomes of most of the United Nations' ​recent COP climate summits have ‌fallen short of the more ambitious action scientists say is needed ​to address climate change, said ​EU climate commissioner Wopke Hoekstra ⁠on Monday.

"If you look at ​what the problem actually needs ​and where the bar should then be, and what most of the COPs ​of the last five, six, ​seven, eight years have delivered, then you ‌just ⁠have to admit that that was underwhelming," Hoekstra told an event hosted by Politico in ​Brussels.
