Breaching 1.5 degrees may only be temporary, the WMO said. Countries pledged in the Paris Climate Agreement to limit global warming to well below 2 degrees – and preferably to 1.5 degrees – compared to pre-industrial temperatures. Scientists consider 1.5 degrees of warming as a key tipping point, beyond which the chances of extreme flooding, drought, wildfires and food shortages could increase dramatically. “This report does not mean that we will permanently exceed the 1.5 degrees Celsius level specified in the Paris Agreement which refers to long-term warming over many years. However, WMO is sounding the alarm that we will breach the 1.5 degrees Celsius level on a temporary basis with increasing frequency,” said WMO Secretary-General Professor Petteri Taalas, in a statement.
