Conservative city councillor Len Clark has been urged to resign over comments he made on climate change.
Labour councillor Kath Hartley (Ladywood), shadow cabinet member for Transportation and Street Services, said Coun Clark (Con Quinton) was "making a fool of himself" by suggesting that global warming did not exist.
Her attack was based on Coun Clark's response to a interim scrutiny report by Labour Councillor Steve Bedser (Longbridge).
The report criticised Birmingham City Council's approach to sustainability as under-resourced, poorly led and lagging behind other local authorities.
Coun Clark described the report as defining virtuous behaviour which was "going down the politically correct route of the usual left-wing Liberal-Labour mob which usually ends up with the Government whacking us over the head with taxes".
In a later interview, Coun Clark said he was suspicious of the scientific evidence behind global warming and believed that it was being used as a ruse by Government to raise taxes.
But last week, Conservative Party headquarters distanced itself from Coun Clark's comments, claiming they were not representative of the party.
Coun Hartley said: "Len Clark is making a fool of himself. He calls for the theories on global warming to be tested. Perhaps he had better look at the UK temperature records for the last three hundred years, or ask the residents of Moseley and King’s Heath about tornados, or New Orleans about flooding.
Coun Clark was not the only critic of Coun Bedser's sustainability report, which was presented to the council earlier this month.
A suggestion that the council should not promote "gas-guzzling" 4x4 vehicles was criticised by deputy Labour group leader Ian Ward (Shard End) as against the interests of Land Rover workers.
Councillor Carl Rice (Lab Ladywood) said the inquiry had produced evidence from council officers who wanted to "build empires more than achieve things".
But Coun Hartley said she believed Labour councillors had wholeheartedly supported Coun Bedser's report.
Instead she lashed out at the Conservative/Liberal coalition's poor recycling record. She said: "Last year Birmingham City Council failed to achieve their recycling target.
"Last council they overturned our motion asking them to review their poor future targets for recycling in the new waste management strategy as they were particularly unchallenging."
Birmingham achieved 17 per cent recycling and composting during 2005/06 – below it's 18 per cent target. This compared to a 2005/06 recycling rate of 18.1 per cent in Coventry and 19 per cent in Manchester. Coun Clark declined to comment
