Wilson and colleagues found that extremes of heat, extremes of cold, oxygen deprivation, and oxidative stress all produce higher rates of mutation in the regions of human DNA that are most prone to mutation. Climate stresses have a unique pathway to produce mutations that involve the stimulation of DNA rereplication. The researchers found that limiting the availability of replication origin-licensing factor CDT1 reduced the rate of mutation.
Comment: There certainly is climate 'change'. The global 'warming' hoax is being exposed and more scientists are warning of global 'cooling'.
The effects of climate and oxygen extremes are seen in normal cells and in disease cells. The effects can promote the increase of disease in normal cells and can speed up the spread of disease in diseased cells and disease producing cells like cancer. The mutation rate due to climate extremes and oxygen availability is also indicated to have played a role in human evolution.
In the event that climate change does produce the extremes of heat that are predicted, then mutation rates in humans will increase. The majority of the mutations will be detrimental to humans. There is the possibility that higher mutation rates could produce positive mutations that could produce "supermen" at least in some aspects of physical or mental ability. The result of climate extremes has been shown to have produced a genetic change in the Sherpa people of Tibet and Nepal in that their muscles retain more oxygen at high altitudes than other people.
Of the many and serious threats to humanity at this time there is one over-riding issue: Fukushima
Name one subject more critical to humanities future - you can't!
Not that there aren't a couple dozen contenders for that throne, it's just that even the worst of them simply cannot match the future legacy of Fukushima. It makes me wonder if people would behave differently towards Fukushima if they could see the radiation, as well as its effects. I wonder. This is the worst surrealistic nightmare ever, with humanity playing Nero as earth burns in Fukushima sunshine.
