| Serious answer, the earth's magnetic field weakening is accelerating [1] [2]. It began declining in 1859 [3] but the changes have increased in recent times, with the magnetic pole shifting significantly such that even airport runways had to be renumbered [4]. The weakening geomagnetic field leaves earth more vulnerable [5] to inclement space weather [6]. It has been shown in mice, the negative behavioral effects of increased space radiation [7]: "Studies in murine models have shown that exposure to high-energy 56Fe particles, which are the largest effective dose contributor in the space radiation environment, impairs cognitive function. These impairments include deficits in spatial learning and memory, object recognition, and operant conditioning, which parallel the cognitive decline observed in aged animals. [...] These behavioural studies, taken together with investigations into low dose HZE radiation effects on neurons and neural tissue, illustrate the risks that space radiation may pose to human health." and [8]: "Acute and chronic tissue alterations arise from the damaging effects of highly energetic charged particles that penetrate the spacecraft and traverse though the tissues of the body. These fully ionized nuclei are derived chiefly from solar ejection events (e.g. protons) or galactic cosmic rays (GCR) composed of light and heavy ions (Z from 1 to 26) Past work with rodents has demonstrated that whole body and/or brain exposure to charged particles can elicit various behavioral decrements that can be linked to impairments in the hippocampus, amygdala, basal forebrain, medial prefrontal cortex (mPFC), and other brain domains." If this model holds true, we can expect things to get worse and worse at an increasing rate in the coming years/decades until the field strengthens.
