The really valuable thing about documenting coral bleaching is that it is this straight, very direct visual indicator of how hot the oceans are getting. If the temperature of the water passes a certain threshold, the corals turn white. It's that simple. There's nothing natural about the cycle that's going on right now. In 2016, we lost 29 percent of the Great Barrier Reef. So 29 percent of the Great Barrier Reef died in a single year, because the water was hot.

The question is not, "Is climate change happening?" Nor is the question, "Is climate change man-made?" Rather, we need to realize itʼs already here, and start asking, "What are we going to do about it?"

We can and must use our combined skills at every opportunity available to address climate change.

Climate change isnʼt a distant threat. Itʼs already changing the way we live.

I believe deeply that every one of us has an individual talent or trait that can be used to make a difference in some way.

I feel a responsibility to get the truth out into the world.
