It is now Earth Hour, where people who worship Gaia over God are supposed to turn off their lights and sit in the dark for one hour.

Which accurately describes the environmentalist movement. Human progress has been the large result of technology and not the Luddites, unless you don’t believe this Facebook post:

I grew up in perpetual earth hour due to crumbling infrastructure. We also had no heating oil in winter, and extremely polluted air. All thanks to central planning in a statist economy. I do not wish that on anyone, but Democrats deserve it.

The Republican Security Council makes a related point:

Hillary Clinton and Bernie Sanders disagree on several key issues but they both agree with President Obama on climate change. They consider it to be our greatest national security threat.
We have been hearing this for a decade. In 2009, former Vice President Al Gore predicted the entire northern polar ice caps would very likely be ice free in 5-7 years.
The reverse has happened and they set a record in 2015 for maximum ice coverage.
Gore predicts sea levels will rise 20 feet over a century, but his Nobel partner, the UN IPCC, is saying it will be 8 inches. The fact is that when it comes to predicting the actual results of climate change, the uncertainty is extremely high.
Nobody has any idea whether any of the policy proposals would have any effect, much less any sizable effect, on the problems predicted by many regarding climate change.
Talking about climate change as a security threat, makes it appear that an unsafe world is safe.
The Democrats need to realize that the real problems are the Islamic State, North Korea, Russia, Iran, China and elsewhere. Wishing these real threats away in favor of climate change doesn’t make them go away.
