CLIMATE CHANGE

JOHN SCALES AVERY—Today, human greed and folly are destroying the global environment. As if this were not enough, there is a great threat to civilization and the biosphere from an all-destroying thermonuclear war. Both of these severe existential threats  are due to faults our inherited emotional nature.

Our emotions have an extremely long evolutionary history. Both lust and rage are emotions that we share with many animals. However, with the rapid advance of human cultural evolution, our ancestors began to live together in progressively larger groups, and in these new societies, our inherited emotional nature was often inappropriate. What once was a survival trait became a sin which needed to be suppressed by morality and law.

GEORGE WUERTHNER—Much of what is burning in the large California fires as well as elsewhere in the West is not forest at all, but chaparral, grasslands, sagebrush, and non-forested habitat. So “active forest management” would have no influence upon much of the acreage currently in flames.

TIM RADFORD—An international team of scientists brings bad news about Arctic heating: the polar ocean is warming not only faster than anybody predicted, it is getting hotter at a rate faster than even the worst case climate scenario predictions have so far foreseen.

Such dramatic rises in Arctic temperatures have been recorded before, but only during the last Ice Age. Evidence from the Greenland ice cores suggests that temperatures rose by 10°C or even 12°C, over a period of between 40 years and a century, between 120,000 years and 11,000 years ago.

MAX BLUMENTHAL—t is hard to think of an American film that provoked a greater backlash in 2020 than “Planet of the Humans.” Focused on the theme of planetary extinction and fanciful proposals to ward it off, the documentary was released for free on YouTube on April 21. The date was significant not only because it was the eve of the 50th anniversary of Earth Day, but because a global pandemic was tearing through America’s social fabric and exposing the human toll of the country’s globalized, growth-obsessed economic model.“The Michael Moore-produced ‘Planet of the Humans’ faced a coordinated suppression campaign led by professional climate activists backed by the same ‘green’ billionaires, Wall Street investors, industry insiders and family foundations skewered in the film.”
