By 2010 the global temperature has gone up by 3 degrees F, and water levels have risen by over a foot. Two million have died by starvation. A temperature rise of 5F is forecast for 2020.

In that decade, there is greater concentration on local energy systems. Societies are reorganizing into smaller communities instead of big cities. Forestry is a major career.

Water is a greater problem. Major rivers in the US and Russia have gone dry. Sea walls are going up to protect coastal cities. Though there is grain growing in the far north, and being transported through newly opened Arctic waters, there is severe drought in the US. And despite the ongoing transformation, the effects of past greenhouse gas emissions continue to multiply and create feedback loops. Ocean plankton, which now absorbs CO2, begins dying because of the hotter water temperatures, and that CO2 is no longer being absorbed.

Without plankton, the only hope for absorbing CO2 becomes the forests. When several South American nations fail to halt deforestation, the PMA organizes a sea and land blockade to force enforcement. Because of the land required for cattle that had resulted in decades of deforestation, beef is so highly taxed that it disappears from most tables.

Still…by 2020 the temperature has risen 5.4 degrees. The sea has risen 2 feet. Between 2025-2040 it has risen 3 feet, breaking into sewage treatment plants and toxic waste dumps, and spreading disease. In 2050, the PMA assesses its half century of crisis management. There have been 20 million deaths by starvation, but only one nuclear exchange (in the Middle East.) Kansas and the Riviera are arid, there are palm trees in Massachusetts. But the civilized world is very different than it was in 2000, and carbon neutrality has been achieved.

But then data from the deep ocean comes in, indicating that melting ice and rain in the far north has added so much fresh water to the oceans that the great ocean conveyor—the deep currents snaking in a particular pattern that sets our climate—is slowing down. The result of warmer water is less carbon being absorbed, so the globe is heating twice as fast. The PMA concludes that carbon emissions will have to be reduced to almost pre-industrial levels of the year 1800.

FutureBurke, who has been upbeat throughout, and lives in a prosperous looking if conspicuously energy efficient dwelling with lots of computerized technology, now mentions that the prospects beyond 2050 could have been a lot better if humanity had used that 20 years---between 1980, when global warming became apparent, and 2000, when the PMA was established—to start action instead of arguing.

He ends with a joke from our era. The one about the man who falls from the top of a skyscraper. As he passes the 17th floor somebody asks him how he’s doing. “So far, so good,” he replies.

So here we are. There seems little use in reciting again what has already happened and is happening now: the hundreds of millions of people displaced by drought and natural disasters, the melting of the Arctic and Antarctic, the slowing down of ocean circulation below the Arctic Circle, the dying and migrations of animal and plant species everywhere, the increase of pest-borne diseases with increased heat. The droughts, the storms, the heat waves—they’ve all become background noise. We’ve had many hotter summers after Greenhouse summer. Flying coast to coast in the US is becoming increasingly difficult because of weather-related delays and cancellations, but it’s just one more of those things, like the idiocy of removing our shoes for Homeland Security.

Clearly there is increasing concern, and even increasing political pressure. Al Gore says that no matter who is elected President in 2008, dealing with the Climate Crisis will be high on his or her agenda. But time is increasingly the problem.

As for our future, a similar speculative program would differ in details, both in terms of what could happen and what the responses would be. But in outline, it's striking how little would be that different. The time scale would probably be extended in some instances, while phenomena we're already seeing isn't predicted. In terms of response, probably no PMA, and maybe new technologies not conceived in 1989 or even now, could be applied. But the basic transformation of energy, society and economies looks realistic---for a scenario that, if it isn't exactly the Best Case, is somewhere in the middle of likelihoods and possibilities.

But we’ve let more than those 20 years go by. Thanks to the Bushies and the soporific effect they’ve had on the media and the public, we’ve lost critical time since 2000, when Bush reversed his campaign pledge to seek mandatory carbon caps, and began the disinformation campaign to question the premise of global heating. How critical? Another speculative view of the Climate Crisis future, next time.
