Global warming view under attack | Stuff.co.nz

A storm has broken out over research saying human activities are not the main factor behind climate change.

The two-year study published in last week's American Geophysical Union's Journal of Geophysical Research by Auckland University climate scientist Chris de Freitas, academic Bob Carter, of James Cook University, Townsville, and Melbourne scientist John McLean concludes that in the past 50 years the average global temperature in the lowest layer of the atmosphere has risen and fallen in agreement with El Nino or La Nina conditions, and not because of increasing greenhouse-gas levels.

De Freitas said yesterday he had received congratulatory messages from overseas about the peer-reviewed research.

However, he was expecting a backlash this week from those who believed greenhouse gases were responsible for climate change.
