The Prime Minister cast a doubt over the very science of climate change only last week, asking how can we possibly have any certainty over what's happening in the climate over decades if we can't predict the weather next week. That seems to me an irresponsible comment, considering the incredible amount of research that's gone into this and your own admission that it is an important and pressing problem. Why would such irresponsible comments be coming from the leadership of your government over such an important issue?
