The Climate Show #20: the boys are back (on Tuvalu) - Hot Topic

Gareth Renowden Oct 20, 2011

Battling against rural broadband that resembled digital molasses (or the bunker oil being pumped out of the Rena), Gareth returns to NZ and joins Glenn Williams and John Cook to discuss drought in Tuvalu, the El Niño Southern Oscillation (ENSO), floods and sea level falls, ocean cooling (that isn’t), solar towers of power and much, [...] … Read More
