Our responsibility to our children

UN-CLIMATE-ENVIRONMENT-GRETA THUNBERG

Greta Thunberg’s speech at the UN has sparked a discussion about our deeper responsibilities to our future generations. When we made the huge effort to fight World War II, did we ask “how much will this cost?” We face the same existential threat and should make the same commitment. We can do this cost effectively, and avoid making most stupid decisions, but asking whether this effort is worth it is now beyond question. We will have to consider how to compensate those who have invested their money or their livelihoods in activities that we now recognize as damaging to the climate, and that will be an added cost to the rest of us. (And we may see this as unfair.) But we really have no choice.

J. Frank Bullit posted on “Fox and Hounds” a sentiment that reflects the core of opposition to such actions:

What if the alarmists are wrong, yet there is no counter to the demands of enacting economic and energy policies we might regret?”

So our energy costs might be a bit more than it would have otherwise, but we get a cleaner environment in exchange. And even now, renewable energy sources are competing well on a dollar to dollar basis.

On the other hand, if the “alarmists” are correct, the consequences have a significant probability of being catastrophic to our civilization, as well as our environment. We all have insurance on our houses for events that we see as highly unlikely. We pay that extra cost on our house to gain assurance that we will recover our investments if such unlikely events occur. These are costs that we are willing to accept because we know that the “alarmists” have a point about the risks of house fires. We should be taking the same attitude towards climate change assessments. It’s not possible to prove that there is no risk, or even that the risk is tiny. And the data trends are sufficiently consistent with the forecasts to date that the probabilities weigh more towards a likelihood than not.

Unless opponents can show that the consequences of the alarmists being wrong are worse than the climate change threat, we have to act to mitigate that risk in much the same way as we do when we buy house insurance. (And by the way, we don’t have another “house” to move to…)
