Australia refuses to commit to net zero emission in next 30 years

The Australian prime minister on Tuesday refused to commit to the UN target of net zero emissions by 2050.

Speaking to reporters, Scott Morrison said: "I won't be signing a blank cheque on behalf of Australians to targets without plans."

“Australians deserve to know the implications and the costs and what the plans are," Morrison added.

On Monday, the UN's Intergovernmental Panel on Climate Change (IPCC) has warned that over the next 20 years, the global temperature is expected to reach or exceed 1.5 degrees Celsius.

A report by the IPCC experts projected that in the coming decades climate changes will increase in all regions, saying for 1.5 degrees Celsius of global warming, there will be increasing heat waves, longer warm seasons and shorter cold seasons.

“At 2°C of global warming, heat extremes would more often reach critical tolerance thresholds for agriculture and health,” the report added.
