News on how global warming is affecting garden produce.

I’m not in denial about global warming — far from it.
I’ve thought it likely that human activity was heating up
the Earth since I read the proceedings of a 1970s hearing
on the subject run by then-Senator Al Gore.

So by now I’m convinced that our dangerously ignorant
species is pushing up the thermostat on the only planet we
have and that global warming is affecting garden produce. But I find it hard to keep that reality uppermost
when I’m under the spell of raspberries, though we’re at
the edge of winter.

For the past few seasons, the fall raspberry plants that
regularly indulge me from August into October have
continued to fruit through strangely warm Novembers; more
improbably, the early bearers are rejoining the party.
Following horticultural orders, I pruned out their fruiting
canes when they finished bearing in July, leaving the new
canes to generate foliage and energy for next year’s crop.
Instead, those newcomers are fruiting now — putting out
small clumps of double-lobed fruit that seem vulnerably out
of season.

It’s tempting to relax and enjoy them, but we all know
there’s a warning underneath the pleasure. When we talked
about this odd weather, Barbara reported the devastations
of Arizona’s worst drought in recorded history — dying
desert animals dragging themselves into back yards,
desperately seeking food and water. There and elsewhere,
wildfires raged throughout the fire season, which we once
called summer.

Here on the East Coast, the fifth year of a prolonged
drought threatened our ability to garden last summer. The
vagaries of climate change now intermittently scorch us,
drench us with unprecedented floods and plunge us into
untimely freezes. That’s the real face of global warming
and what we’ll need to expect in the
future — chronically unstable weather, marked by
extremes of temperature and moisture that will allow us to
produce food normally only part of the time.
