Two years ago, we were all getting very excited in the run-up to the United Nations Framework Convention on Climate Change at Copenhagen. Its perceived failure was a big disappointment. Now, we are barely three weeks away from the start of this year's equivalent COP - 17 - to be held in Durban: nobody seems to be holding their breath, but that doesn't mean to say people shouldn't be praying for a positive outcome this time round. And that's the purpose of Hope for Creation, a day of prayer - today - for action on climate change: Christians in 60 countries around the world have signed up.
Right on cue, I read yesterday of both good news and bad news: the latter first - a record rise in greenhouse gas emissions is reported, putting global warming ahead of the worst-case scenarios envisaged by scientists.
And the good news? China's lightbulb moment. Incandescent bulbs are being phased out in the Peoples' Republic over a five-year period, which is more than the US is committed to.
I photographed this fennel head just over a week ago: it has self-seeded in amongst the carrots.
