Al Gore’s contribution to the global climate change debate is not in question and he has, along with the IPCC, been awarded the 2007 Nobel Peace Prize for his work in raising awareness. If you haven’t seen his film “An inconvenient truth” then do get hold of the DVD – it may just be the most interesting PowerPoint presentation you will ever see! However, does he really understand the nature of the debate? The article below suggests that he has not yet taken account of the most fundamental trade-off in dealing with climate change – the trade-off between our own quality of life and that of our descendants in the future.

Cement may be quietly emerging as one of the biggest obstacles to lowering carbon emissions to reduce the extent of global warming. The cement industry rarely features in media analysis of the ‘worst polluters’, but in fact the industry is responsible, because of the high energy requirements of manufacture, for more than 5% of carbon dioxide emissions. A building boom globally has fuelled demand for the material. Concrete is the second most used product on the planet, after water, so what can be done to reduce the impact of the industry on the environment?

The rapid growth in the use of overseas and agency staff for many lower paid jobs has been a contentious issue for many in the trade union movement. Unions have demanded the same rights for agency staff as for permanent staff, but the government is reluctant to do this, arguing that the use of agency staff encourages flexibility in the workforce.
