As a long-term nature observer and gardener, there are many signs of climate change. The most striking are extreme weather patterns. Predicted by a number of climate change models, variability in rainfall and temperatures may be the most telling indicators. In my part of the world, we've seen warmer winters (in night-time lows), drought and deluge (definitely yes), and drier summers (certainly in the recent decade of drought).
Is this 'normal'?
Maybe, but it seems to indicate that increasingly, human-induced inputs are affecting global climatic patterns in unprecedented ways.
I'm glad to lend a voice to Blog Action Day efforts to promote awareness on this issue.
