Surprised by the sun

El Niño

There has been much talk of another El Niño occurring here in 2015.

What that means for South Australians is a hotter, drier summer season,
with the attendant drought and bushfire risks.

This winter, all the flowering plants (native and non-native)
seem to be flowering early.

It’s pretty, if a little unsettling.

I wonder:
Can plants sense this kind of thing before it happens?
