For example: "There are warnings of a new El Nino and the latest drought statement released by the Bureau of Meteorology shows the last three months were the warmest ever." Ever? I think they mean since they first started taking records. At least they don't invoke global warming, which is my beef with the Breakfast story. As far as I understand dimming it's an issue no matter where you are on the globe - it doesn't just affect polluted areas. It is also a similar effect in some respects to what you get from water vapour. Which may provide a clue as to why we've had such a hot summer, without having to invoke greenhouse to explain it (I don't deny the greenhouse effect by the way, I'm just sceptical of some of the claims). I've noticed that the temperature has been hotter. I've also noticed that the spread between maxima and minima over the course of a day has tended to be larger than the standard 10 degrees that we normally get. This would be consistent with there being less cloud cover. Clouds tend to reflect sunlight upwards, similarly to global dimming, making maxima less pronounced, and they tend to reflect heat downwards, making minima higher. My understanding of the reason for there being less rain is that it is related to El Nino, which is not affected, as far as I am aware, by greenhouse. So, assuming the above is correct, then our hotter temperatures are likely to be related to El Nino rather than greenhouse, adn so offer no support to the Kiribati story.

As far as I understand dimming it’s an issue no matter where you are on the globe – it doesn’t just affect polluted areas.
