The real question here is how does the climate change relate to the growing size of the blue whales? But the answer is rather simple.
Climate change and the sudden glaciation that marked the Ice Ages reshaped the food supply for the blue whales.
As we all know, the blue whale, one of 12 species of baleen whales, feeds on planktonic crustaceans called krill. And with their filter-feeder system, they are able to obtain the huge amounts of prey that is high in nutrients.
So when glaciation began, it washed krill into coastal waters, where the blue whales live, boosting their food supplies. And given the fact that they take 125% of their body weight, it's no wonder they have grown so big.

If there is one thing we have learned from this research that would certainly be how climate change can influence a life on this planet.
Going back to the Ice Ages, we saw the change that turned blue whales into giants. And today, with a climate constantly changing, let's just hope that they don't reduce in both size and the number.
