The choice for Climate Change as the subject on Blog Action Day implies there is consensus about climate change, at least that the climate is actually changing to an extent it is affecting our world. There is no full consensus though, nor has there been in the past. There is and has been always, a battle of facts.
A good source for getting informed on the issue, unfortunately, is a podcast lecture series from UCSD, that has been taken off line. It will be back though at some time in the future and therefore I'd advice you to keep your eyes open for it: BILD 18, Human impact on the environment. Last summer, when the course ran and the lectures were available, lecture 10 paid attention to the problems the early believers in climate change had to get their voice heard. Even today, the speaker notes, speaking of climate change and the specifics of fatal pollution, will find politically and ideologically motivated blockades.
Alternately, now that there is a much wider consensus the climate actually IS changing, those who are not so convinced are finding it difficult to be heard. And just as the previous speaker marked how political, ideological and mostly business interests battled the facts, the other side speaks of alarmists. On the UChannel Podcast, one such speaker was Lord Lawson and he not only downplays the actual change of the climate, also he claims that whatever change is there is not human caused change, nor is it as harmful as usually is projected.
Next, I will write about the battle of the price - how much is climate change going to cost and who will pay?
