Carbon-Free Sailors Saved by Carbon-Heavy Oil Tanker

The BBC reports:

An expedition team which set sail from Plymouth on a 5,000-mile carbon emission-free trip to Greenland have been rescued by an oil tanker.
…
The team, which left Mount Batten Marina in Plymouth on 19 April in a boat named the Fleur, aimed to rely on sail, solar and man power on a 580-mile (933km/h) journey to and from the highest point of the Greenland ice cap.

The expedition was followed by up to 40 schools across the UK to promote climate change awareness.

So an environmentalist stunt designed to indoctrinate children about the wonders of a green economy turns into a lesson about the dependability and necessity of carbon based energy. One might call it irony. We like to think of it as justice.
