UN analysts said on Tuesday a report from the world’s climate scientists addressing the impacts of accelerating climate change is due out on August 9.
“We are now observing climate change with our own eyes in ways we did not broadly before,” said the University of East Anglia climate scientist Corinne Le Quere who is also an author of the upcoming assessment by the Intergovernmental Panel on Climate Change (IPCC).
The report is compiled by the world’s top scientists and signed off by governments. It examines physical changes caused by climate change and predicts future impacts.
It is expected the report confirms the Paris Agreement on climate change will not be met soon and that the current effort to hold global warming to 1.5 degrees Celsius above preindustrial times is insufficient.
The report estimates the possibility of future “black swan” events or events of low probability with high impacts such as the melting of major ice sheets that increase global sea levels.
“The fact we’re starting to see some of the impacts of climate change… really ought to be a wake-up call for global governments that this isn’t something they can ignore,” University of Cambridge climate scientist Emily Shuckburgh.
“We’re seeing the impacts here and now today, and the impacts are going to get worse unless we take immediate action,” she added.
According to Le Quere, the report will show that human activities are driving climate change at a rate higher than that of the one recorded in the previous flagship report in 2013.
She added that as the emissions of greenhouse gasses and global average temperature are still on the rise, “obviously [the conviction] will be stronger than what we had in the past”.
