Tony Abbott has ordered his troops to focus on the government during what will be a protracted climate change debate and to shelve their personal views so they do not become distracted by an internal fight over whether global warming is real.

Mr Abbott issued the edict to his party room yesterday as the independent MP, Tony Windsor - one target of Mr Abbott's call for a ''people's revolt'' - revealed he had received death threats.

Mr Windsor told the Seven Network that unless the harsh language of the debate so far was toned down, inside Parliament and on talkback radio, there could be another shooting like that of the Arizona congresswoman Gabrielle Giffords.

''We're getting very close … to going over the edge,'' he said.

Mr Abbott called yesterday for ''tens of thousands of people'' to ''bombard'' Labor and independent MPs with emails, phone calls and letters, and to bail them up in the street.
