Like predators on the Serengeti, critics will zero-in on the weakest parts. Ozone depletion over the Antarctic could expose whales to damaging solar radiation, which could impact on future whale stocks. The problems with that statement are numerous beginning with the obvious. Solar radiation is fundamentally necessary for whales. It's called summer.
Solar radiation gets the food pyramid started.
Without it, carbon-based life forms have no source of energy. Additionally, the most recent report on the ozone hole suggests the hole is actually shrinking. Numerous global temperature oscillations occurred in between with a half dozen warming trends occurring just in the past 10,000 years, each more significant than our current state. We are now in just another relatively minor warming trend. A significant climate change may genetically isolate some stocks leading to spearate species.
