How often in discussions and informal chats with gardeners, and other people who notice the ebb and flow of nature, have I heard comments over recent years to the effect that things are changing, signs of spring are appearing earlier. I would be surprised if there was anything but a significant majority of gardeners agreeing with the science that global warming is real and happening now.
In a recent letter my brother-in-law in Canada, not only a keen gardener, but also a meteorologist expressed concern that, if anything, the message getting through to most of us isn't stark and horrendous enough in its warnings.
