Climate change is a major crisis, don’t get me wrong, and it’s something that needs to be discussed extensively in both scientific and policy circles. We’re pumping carbon dioxide into the atmosphere at rather too high a rate, and getting something done about that is a key priority.
It’s possible, though, to take the obsession on climate and CO_2 a little too far, though. Such as this news story from Physics World:
A cosmic gamma-ray burst striking the Earth could be harmful to ocean plankton at depths of up to 75 m, according to a team of Cuban researchers. These organisms account for up to 40% of the ocean’s photosynthesis, so such an event could have a serious impact on Earth’s carbon dioxide levels.
You know, call me crazy, but I suspect that in the wake of a gamma-ray burst striking the Earth with enough radiation to damage plankton at a depth of 75m, we’ll have problems a little more immediate than the carbon dioxide level of the atmosphere…
And on that cheery note, have a nice weekend!
