This is Not Cool. Heatwave 2011.
Peter Sinclair talks about the current heat wave - there are important things to watch for that are good indicators of man made CO2 warming.
The first is that the average overnight temperature is rising, there’s no better demonstration of the Greenhouse effect outside of an actual greenhouse.
The second is that this year’s heat wave comes without a corresponding El Nino warming current — we are in a neutral period without an El Nino to warm or a La Nina to cool.
