The frog in the future!

Due to global warming things are changing, animals are changing, cities are sinking. Everything is weird but what most importantly, what will happen to animals? Will they die off or will they adapt? Well let's say they adapt to the environment, for example the frog. Let's say our frog is blue and has black spots and it's poisonous. It lives in the Amazon Rainforest and lives off of bugs. This frog is adapted to how the Earth was million years ago. But now it has to adapt to be able to survive in hotter and drier weather. Usually it takes about one million years to adapt, but let's say it can adapt in 20,000 years. The frog would turn to look like a lizard, long and small. It would adapt to this due to it not being fast enough to catch food, but when it's a lizard it's faster.
