It seems clear now that the effects of human industry and civilization of shaping the Earth’s climate as never before. The fruits of scientific forecasting permit us a glimpse of the next 84 years of our planet’s ecological and biophysical history. One thing seems certain-it promises to be a strange, even frightening, new world.
Europe experiences an increased incidence of flash flooding; meanwhile, agricultural yields decrease by up to 50% in some parts of the world due to less rainfall.
5 billion people face periodic water shortages. Melting permafrost in the Arctic releases 190 gigatons of greenhouse gases, further amplifying the current warming trend.
Ocean acidification destroys 18% of the planet’s coral reefs; in Asia alone, coral loss amounts to 30% meanwhile, temperate glaciers disappear altogether on the equatorial mountains of Africa, and the Arctic sea is now completely ice-free in the summer.
The period of the so-called “climate departure” -a point of no return, when average temperatures become so impacted by the evolving climate that a feedback loop obtains, and the “old” climatic conditions disappear entirely.
Fully a quarter of the world’s plant and vertebrate animal species face extinction; and ocean acidification kills off most remaining coral reefs. Small alpine glaciers disappear completely, and large glaciers shrink by up to 70%. Meanwhile, horrendous heat waves prove fatal in major cities throughout the world.
Warmer, drier conditions lead to more frequent and longer droughts, heat waves and fire-seasons. Drought causes decrease in world hydropower electricity production; total European hydroelectric capacity declines 6%, while in the Mediterranean the decrease is up to 50%.
Some parts of the world are desiccated, others are Inundated; sea levels around New York City rise by more than three feet. 100 million people experience coastal flooding each year; between 1.1 and 3.2 billion people experience water shortages.
The “boosting” of tropical climate zones into higher latitudes greatly expands the geographical reach of numerous tropical disease vectors; pathogens like Dengue fever, Zika and West Nile virus now have access to much of humankind.
Atmospheric carbon dioxide reaches 840 ppmv, its highest level in the past 650, 000 years. New climate zones appear on up to 39% of Earth’s land surface, transforming the planet’s surface features increased droughts create “Dust Bowl” environments throughout the world.
In response to the multiplying threats confronting mankind, the world governments make common cause to halt and reverse global climate change. Using space-based sunshades cloud-seeding technologies, and chemical carbon sequestration, Earth’s fever abates and begins to recede..
