How do you know it's hot in Australia?
Because pictures of cuddly koalas accosting humans and begging them for water are circulating on the web again.
Well, that and all the news reports about how it's obscenely hot in Australia.
But back to the koalas for a moment.
Koalas don't even drink that much water. They usually get what hydration they need from eucalyptus leaves.
But with Australia bracing for some of the hottest October days on record, these adorable icons of Down Under are being forced into compromising positions.
Here, one little guy was so thirsty, he found the courage to stop a cyclist and ask for a swig off his water bottle.
And this little guy couldn't help but trespass in someone's garden looking for a drink.
The pictures, from what we can tell, aren't new. They seem to have originated in the late 2000s and resurface along with the heatwave in Australia every year.
But they nonetheless convey the current climate in Australia, and illustrate, albeit in a humorous fashion, the extreme lengths to which animals are going to cope with global warming.
Some are getting skinny or changing what they eat. Some are changing where they live and when they migrate. And some are just like, "you, with the water bottle, give it here."
Temperatures have been creeping so high in Australia in recent months that the Bureau of Meteorology had to invent new colors for its weather forecasting chart — deep purple and pink now mean, koalas be dang thirsty.
