The Conservatives don’t debate climate change until the Wednesday of their conference here in Blackpool but in the packed corridors and bars of the Imperial Hotel on the seaside resort’s front there is one common complaint - the heat.
Perhaps it’s a testament to the power of human bodies to generate their own warmth, but the atmosphere in the crowded rooms during fringe debates is near-tropical.
Conservative party delegates tend to dress more formally than their Labour or Liberal Democrat counterparts, but in side-meetings here jackets are carried over sleeves or shoulders as their red-faced owners fan themselves with policy handouts and brochures.
One enterprising organisation has even produced folding fans imprinted with their message to keep the party activists cool.
The heavy climate adds to the political temperature, but there is little evidence delegates are taking it out on the party leadership.
In a BBC-sponsored debate on Sunday evening, provocatively titled “David Cameron — Out Of Touch With His Own Party?”, members refused to take the bait and criticise their leader.
Instead they had to be restrained from turning the event into an attack on what they claimed was the broadcaster’s bias against the Tories.
Despite a robust defence by BBC radio host Martha Kearney, it was Spectator columnist Peter Oborne who won the meeting’s biggest round of applause for a dig at the broadcaster.
He said the BBC would have “massacred” any conservative minister who called, as Prime Minister Gordon Brown did last week, for British jobs for British workers and for the repatriation of criminals.
MP Jeremy Hunt, the party’s media spokesman, weighed in with his own warning to the broadcaster.
“It is very important for the BBC to understand that it doesn’t just report political culture, it creates the political culture,” he said.
“If your view about politicians is that we are all lying bastards, then in the end that is the view that the country will start to adopt.”
After the heat of the meeting it was time for the conference traffic jam, with delegates from two other events ending at the same time turning the narrow wood-panelled corridor outside into a solid, unmoving block of perspiring delegates, waiters and food trolleys.
“It’s worse than the Tower of London in here,” one delegate commented. But no crown jewels — just the warmth and close press of fellow activists.
