I've recently finished reading David Wallace-Wells' book The Uninhabitable Earth. It is a sobering, terrifying, and absolutely essential book. It also offers a potent counter to the many lies that we hear and tell ourselves about global warming.
Lie Number 1: This is an issue about prior and future generations.
More than half of all greenhouse gasses released into the atmosphere have been released since 1990. Some changes and warming are already unavoidable. But, if we do not make radical reductions in human emissions by 2050, the damage will be catastrophic and irreversible.
The vast majority of greenhouse admissions have happened and will continue to happen during our lifetimes. Most of it has occurred since we became aware of the dangers of global warming. And it will continue to compound indefinitely. If we do not act then we will condemn all of humanity for every future generation. That sounds like a ridiculous exaggeration. It isn't one.
We, the people alive today, have the only chance to address this problem.
Lie Number 2: It won't be that bad. "Nature lovers" might care, but humanity will be fine.
We are already beginning to see the effects of a warming world: more hurricanes, more wildfires, flooding, heat waves, etc... This is the very beginning. It will continue and it will continue to get worse. As the temperatures rise, year after year, tiny increases - fractions of a degree in a global average - will have a compounding and relentless effect.
Wildfires will continue to eradicate communities. Higher temperatures will render much of the earth essentially uninhabitable. Storms will overwhelm and flood areas where people live on a regular basis - including many of our largest and most populous cities. Water supplies will dry up. Heat waves and droughts will endanger much of the world's food supply. Season after season.Year after year. Without end. The cumulative effect will lead to massive migration, dislocation, and unrest.
Our current path puts us on course for a world that is very different from the one we live in. This is not in some far-flung future. We are seeing it now. We'll continue to see the effects accumulate in the years and decades to come. By the end of this century, the world could be violently transformed. And the changes will continue.
Lie Number 3: We have bigger problems right now.
With most policy, political, and societal issues we can make changes. Politicians serve limited terms. They can be voted out. Their policies can be reversed. Tax policies can be altered. Health care plans can be enacted. The process of change can be slow, partial, and infuriating. But with time and enough dissatisfied voters, it can happen.
Or sometimes change doesn't happen. We muddle along for decades dealing with inefficiencies, sub-optimal conditions, and even gross injustice. But, we can. We do. We muddle along. Life goes on. And when the conditions are finally right for a change, it can happen.
Global warming is not like that. If the good people of 2040 or 2062 or 2087 decide that they have had enough - it will be too late. If they decide, only then, to get serious, then we will be on the wrong side of irreversible. Dramatic action in future years can prevent an even worse fate. It won't allow them to un-melt the glaciers, refill aquifers, or turn parched fallow fields back into fertile land.
The time to act to is now. We can continue to strive for progress elsewhere. But we really don't have more important issues to work on.
Lie number 4: This is a partisan issue.
Nobody will escape the effects of catastrophic climate change. It doesn't matter where you live. Rural, urban, north, south, coastal, inland - everyone will be affected. We're all in this together. And everything and everyone you care about is under threat.
We know that tribalism has an extremely powerful pull. We can see that the human capacity for rationalization is limitless. You can find reasons to look away, to ignore the problem, to oppose the solutions, to wait-and-see. There is no shortage of people offering convenient excuses and lies.
But you can choose to see the truth. You can choose to confront it and all of it's terrible implications. You can support, request, require, and demand action. And when you do, you can do so knowing it the right and necessary thing to do.
Lie number 5: It's already too late
It is not too late to act. We've been slow to act. At this point, some warming is inevitable. But it's not too late to achieve a stable, sustainable world. It's not too late to leave our children and grandchildren a world that is recognizably similar to the one we inherited.
We have the technology today. And that technology will continue to improve. We can see the extent of the problem. The solutions are known. Changes will be needed. We'll all be asked to make sacrifices. There will be costs. But the cost of inaction will greatly exceed of costs of doing what needs to be done.
This is the fundamental challenge of our time. But it's not too late to embrace it.
