Good morning. The climate crisis is a hot topic today as the world gears up for virtual summit of 40 world leaders, where new commitments from the biggest carbon emitters are expected to meet the Paris agreement's ambitions.

Australia will not be able to fly under the radar" over climate crisis policies. International pressure on the government is expected to increase as other countries make new pledges to cut greenhouse gas emissions over the next 10 years. In the US Joe Biden has promised to unveil his plan to cut emissions by 2030 before he hosts a virtual summit of 40 national leaders on Thursday.

Scott Morrison said his government would not sacrifice our traditional industries" in regional areas by taxing emissions to reach the goal.
