Rather than switch off lights to show their support for Earth Hour on Saturday from 8:30 to 9:30 pm local time, the public should switch off Earth Hour. While the event has expanded from its original focus on the impossible goal of ‘stopping climate change,’ global warming is still a primary rationale.
Earth Hour activists seem not to know that climate has been changing, at times far faster than today, for billions of years, and it will continue to change no matter what we do. Yet their spokespeople have insisted that natural climate drivers such as changes in cloud cover, ocean currents and the Sun are dwarfed by the impact of carbon dioxide (CO2) emissions from fossil fuels, the source of most of world’s energy consumption. They have told us that climate catastrophe lies ahead unless we spend vast sums to change the way we generate energy.
