On October 9, 1913, President Woodrow Wilson opened the Panama Canal by dynamiting the final dikes holding the water at bay.

He did it from the comfort of the White House, keying a telegraph transmitter that set off the explosion from over 2,000 miles away.

In the 103 years since Wilson pushed that button, the Panama Canal has become an international shipping bottleneck, as container ships grew too large for its aging locks.

Jail climate deniers

Nowhere is the battle for hearts and minds more fierce than in the climate field – Kath sends this:

Global warming deniers are similar to corporate criminals such as Enron executives – and the government should consider jailing them.

TV scientist Bill Nye – aka Bill Nye the Science Guy – voiced this controversial opinion in an interview released on YouTube, which will feature in a new documentary, Climate Hustle.

He was responding to previous calls from activists for climate change deniers to be jailed – and said, ‘Well, we’ll see what happens.’

Nye asks, ‘Was it appropriate to jail the guys from Enron? Was it appropriate to jail people from the cigarette industry who insisted that this addictive product was not addictive and so on?

Jailed for denying a beat-up, eh? Why do we not incarcerate those idiots in New York who continue their racism, attacking Trump for their own faults?…
