"There’s a piece of gardening lore in my hometown which has been passed down
for generations: never plant your tomatoes before Show Day, which, in Tasmania,
is the fourth Saturday in October. If you’re foolhardy enough to plant them
earlier, your tomato seedlings will suffer during the cold nights and won’t
grow.
But does this kind of seasonal wisdom still work as the climate warps? We often
talk about climate change in large-scale ways – how much the global average
surface temperature will increase.
Nations are trying to keep the temperature rise well under 2℃. Taken as an
average, that sounds tiny – after all, the temperature varies much more than
that when day gives way to night. But remember – before the industrial
revolution, the world’s average surface temperature was 12.1℃. Now it’s almost
a degree hotter – and could be up to 3℃ hotter by the end of the century if
high emissions continue.
For many of us, climate change can seem abstract. But the natural world is very
sensitive to temperature change. Wherever we look, we can see that the seasons
are changing. Gardening lore no longer holds. Flowering may happen earlier.
Many species have to move or die. Here’s what you might notice."
