Flash floods in Pakistan kill at least 27
Good news from the Carribean as 1st named storm of the season largely by-passes Haiti - although Ana had been downgraded to a tropical depression, so winds were not especially strong, the concern was about how much rain it would drop - Haiti being one of the countries worst affected by massive deforestation and consequent flooding and landslides. Meanwhile Hurricane Bill strengthens on track to Bermuda.
Agricultural methods of early civilisations may have altered global climate - or maybe not. I'm with those who think that such actions were not on nearly a big enough scale to have any major effect (though obviously in places they had significant local consequences, especially regarding rainfall and desertificiation).
Ancient climate: the greenhouse gas that saved the world - a new solution to the Faint Young Sun Paradox?
