Don't be entirely duped by this sky - it was getting warm by mid-afternoon (and I don't just mean indoors, as a result of the mended boiler), but it still looks very brown and grey and barren outside. This is the same dryness that, together with strong winds, is causing the terrible fires in Oklahoma and the Texas panhandle. Global warming? Well, let's just say that I was really grateful to be introduced to the website I See Change - a "community climate and weather journal" - thanks to a program on NPR. This is a form of crowd-sourced observation, recording all the tiny signs of change in nature - like mosquitoes appearing unseasonably early - and real testimony to the importance of detailed observation when it comes not just to knowing detail, but understanding its relationship to a whole.
