Anthropocene declared officially

The offical declaration of a new geological epoch is reported in a number of press articles at the end of August 2016:

The Anthropocene Is Here: Humanity Has Pushed Earth Into a New Epoch

The epoch is thought to have begun in the 1950s, when human activity set global systems on a different trajectory

The Anthropocene Epoch has begun, according to a group of experts assembled at the International Geological Congress in Cape Town, South Africa this week.

After seven years of deliberation, members of an international working group votedunanimously on Monday to acknowledge that the Anthropocene—a geologic time interval so-dubbed by chemists Paul Crutzen and Eugene Stoermer in 2000—is real.

The epoch is thought to have begun in the 1950s, when human activity, namely rapid industrialization and nuclear activity, set global systems on a different trajectory. And there’s evidence in the geographic record. Indeed, scientists say that nuclear bomb testing, industrial agriculture, human-caused global warming, and the proliferation of plastic across the globe have so profoundly altered the planet that it is time to declare the 11,700-year Holocene over.

Here is a reflection on the above news. It raised the issue that humans are now co-creators of the planet that gave rise to organic life. The passengers of Spaceship Earth are now unwittingly re-making their spacecraft through their expansionist behaviour designed to satify their passion for growth, irrespective of the long-term consequences for future generations.

Climate change denial’s new tag

Brexit was a tag that led to a vote for the UK to leave the EU. Now the doggedly persistent climate change deniers have coined their campaign “CLEXIT” which is a catchy tag that they hope will  advance their desire to curb concerns about greenhouse gas emissions and anthropgenic global warming and to ‘exit’ from policies designed to ameliorate emissions from fossil fuels generally thought to  be responsible for climate disruption. See this link to  their dissenting views.
