A presentation was launched last month by the UK climate ministry. It is a Google Earth (*.KML file or plugin) which ‘highlights some of the changes that may occur if the global average temperature rises by 4°C above the pre-industrial climate average.’
It spurns us, not just in the UK or the US – where a potential congressional climate bill was recently abandoned due to mostly right wing opposition – but everywhere to make sure we do our part not only at the ballot box but by our daily actions to help alleviate or eliminate such bleak future scenarios.
