Keeping it simple, here’s the elevator speech for climate marchers, excerpted from a more lengthy article linked below.
Expect more craziness this weekend. Earth Day is Saturday. This year’s theme: Government must “do more” about climate change because “consequences of inaction are too high to risk.”
They make it sound so simple:
1) Man causes global warming.
2) Warming is obviously harmful.
3) Government can stop it.
Each claim is dubious or wrong.
1) Man’s greenhouse gases contribute to warming, but scientists don’t agree on how much. Of 117 climate models from the 1990s, 114 overpredicted warming.
2) Warming is harmful. Maybe.
But so far it’s been good: Over the last century, climates warmed, but climate-related deaths dropped. Since 1933, they fell by 98 percent. Life expectancy doubled.
Much of that is thanks to prosperity created by free markets. But some is due to warming. Cold kills more people than heat.
Carbon dioxide is also good for crop growth. Even The New York Times admits, “Plants have been growing at a rate far faster than at any other time in the last 54,000 years.”
3) Nothing we do today will stop global warming. The Obama regulations that Trump recently repealed, horrifying the Earth Day crowd, had a goal that amounted to a mere 1 percent reduction in global CO2. And that was just the goal.
Of course, some think any cut is better than nothing. But cuts are costly. They kill jobs, opportunity. All to accomplish… nothing the earth will notice.
If warming does become a problem, we’re better off if our economy is very strong when the science tells us clearly that action will make a difference.
We should be especially wary of expensive government projects given how often alarmists were wrong in the past.
The alarmists claim they’re marching for “science,” but they’re really marching for a left-wing religion. Instead we should celebrate human progress and our ability to use energy to improve everyone’s quality of life.
