ABC hails hot day in Brisbane as "climate change" Global warming alarmism on the ABC's Insiders: BARRIE CASSIDY: And I understand the temperature will reach at least 40 degrees in Brisbane today, so climate change has arrived certainly in more ways than one it seems at this conference. Would Cassidy have said the same if the G20 had been held in the US instead: Record-setting cold continues for another day on Thursday in the Central U.S., where frigid temperatures are hovering to 45 degrees below average. Casper, Wyo., fell to a low temperature of minus 27 degrees on Wednesday night, which breaks the record for all-time November low temperature of minus 21 degrees, set in 1985. Overnight lows in Denver, Colo., plummeted to 14 degrees below zero, which ties the record for second coldest temperature in November.
