Climate change is one of the greatest threats that humankind faces in the 21st century. The next hundred years could see coastlines and islands submerged, and a surge in heatwaves, hurricanes, droughts, floods and therefore in pests, disease, famine and displacement. While government and industry dither, this book argues, we could all cut our personal greenhouse gas emissions by 60% - the level necessary to halt the current trend according to the Intergovernmental Panel on Climate Change. After summarising today's state of affairs, scientifically and politically, climatologist Dave Reay explores the climate impact of housing, gardening, food, money, work, transport, death even. Packed with provocative case studies, calculations, and lifestyle comparisons, this entertaining and authoritative book makes the complexities of climatology tractable and challenges readers to rethink their notions of 'doing their bit'.
