Climate change realities
In a perplexing, worthwhile, but quite long, article on The New Yorker, Bill McKibben describes the reality of the world’s situation towards climate change. If the second half tends to go nowhere as interesting as the title promises, they are some good bits to be shared here. A quick selection:
Late in 2017, a United Nations agency announced that the number of chronically malnourished people in the world, after a decade of decline, had started to grow again—by thirty-eight million, to a total of eight hundred and fifteen million,” largely due to the proliferation of violent conflicts and climate-related shocks.”
Then this one:
Two centuries ago, the concentration of CO2 in the atmosphere was two hundred and seventy-five parts per million; it has now topped four hundred parts per million and is rising more than two parts per million each year. The extra heat that we trap near the planet every day is equivalent to the heat from four hundred thousand bombs the size of the one that was dropped on Hiroshima.
An old classic:
Nine of the ten deadliest heat waves in human history have occurred since 2000.
By 2070, tropical regions that now get one day of truly oppressive humid heat a year can expect between a hundred and two hundred and fifty days, if the current levels of greenhouse-gas emissions continue.
By 2050, if temperatures rise by two degrees a quarter of the earth will experience serious drought and desertification. The early signs are clear: São Paulo came within days of running out of water last year, as did Cape Town this spring. In the fall, a record drought in Germany lowered the level of the Elbe to below twenty inches and reduced the corn harvest by forty per cent.
Alex Steffen, an environmental writer, coined the term “predatory delay” to describe “the blocking or slowing of needed change, in order to make money off unsustainable, unjust systems in the meantime.” The behaviour of the oil companies, which have pulled off perhaps the most consequential deception in mankind’s history, is a prime example.
And the kicker:
This past May, a team of scientists from the University of Illinois reported that there was a thirty-five-per-cent chance that, because of unexpectedly high economic growth rates, the U.N.’s “worst-case scenario” for global warming was too optimistic. “We are now truly in uncharted territory.
Worrisome to say the least.
