Negotiations began on Monday to approve a UN science report which will anchor high level summits later this year, charged with boosting climate action worldwide.

The assessment comes as record-breaking heat waves, devastating floods and drought struck across three continents in recent weeks.

Intergovernmental Panel on Climate Change (IPCC) Chair, Hoesung Lee, told the opening session of the meeting that this report, has been prepared in exceptional circumstances, and this is an unprecedented IPCC approval session.

The report, Climate Change 2021: the Physical Science Basis, by IPCC Working Group, brings together the latest advances in climate science and multiple lines of evidence to provide an up-to-date physical understanding of the climate system and climate change.
