So what is wrong with the latest story out of Japan? The problem is the assertion that the annual occurrence of jellyfish off the coast of Japan is special. There are two things to note:
1. They were there 40 years ago, so its not such a stretch to go from one year to a few.
2. More importantly, we can see from the chart above that the Earth's global average temperature is lower than it was in 900AD, a period which pre-dates human impact on the climate, and that we can expect warmer temperatures for the next 50-100 years, and that would be perfectly within the pattern of previous cycles.
3. Warmer temperatures are actually conducive to greater oxygen production, as its the planets way of adjusting to such rises in CO2 levels, if it were a concern.
The issue of whether humanity could long term impact on the climate (even if there is no evidence of a current impact) is addressed in the presentation in the previous post by Woods (2008).
The emptiness of such assertions are balanced by more 'neutral' reporting. This journalist from the UK Telegraph suggests little is known about these jellyfish. Nice to have an honest confession. But at least he highlights something about the erratic nature of their numbers and migration.
