It was supposed to be the climate change election. It hasn't turned out that way so far, even if it is a sign of progress that all the parties have detailed climate proposals in their manifestos, says Joseph Curtin, a climate change expert working in the NGO sector and a member of the Climate Change Advisory Council.
