Weather stations which produced data pointing towards man-made global warming may have been compromised by local conditions, a new report suggests.

The report co-written by Anthony Watts, an American meteorologist and climate sceptic, shows photographs of weather stations near heat-generating equipment which could be distorting their readings.

Some are next to air-conditioning units or on waste-treatment plants, while one sits alongside a waste incinerator. A weather station at Rome airport was found to catch the hot exhaust fumes emitted by taxiing jets.
