With the intense heat and fires now raging in Australia, parts of the country have been dealing with "pyrocumulonimbus" clouds - weather systems generated by the intense heat of the fires themselves, which bringing little rain but are packed with lightning that can spark new fires.

Even if the birds escaped the blazes, it's unclear whether they'll survive now that their habitat has been destroyed by the fires.
And many hot spots on the island continue to burn.
She said she is now writing the final chapter of the thesis she began in 2016, but that suddenly everything has changed.
